It consists of a simple script language, in which you can create, combine and transform audio sources. Its design makes liquidsoap flexible and easily extensible. .

Added support for multiple metadata fields in ogg and flac metadata - Added support for track-level REM ALBUM in cue file parsing (#4381) Changed: - Added `"pic"` to list of excluded metadata for automatic charset conversion. - Added `settings.charset.max_string_length` setting to prevent automatic charset conversions of strings over that length. Fixed: - Optimized CPU usage (#4369, #4370) - Fixed empty initial HLS segment (#4401) - Fixed support for `duration` metadata in image decoder (#4397) - Fixed cue-out bug in cue file parsing (#4381) - Bring back parse error location. (#4362) - Fixed SRT encoding when restarting a stream with reverse data flow (#4399) - Make sure that audioscrobbler `on_track`/`on_end` operations are sent to a asynchronous task queue. - Fixed resources accumulation leading to catchup when using `crossfade` (#4419, #4410) - Fixed source reselection logic issue that was causing crashes when using `switch` and `fallback` operators (#4420) - Fixed self-sync logic with pulse audio outputs (#4429) - Fixed script caching on windows. --- # 2.3.1 (2025-02-05) New: - Added support for address resolution preference in SRT (#4317) - Added global address resolution settings for SRT and Icecast (#4317) - Added support for parsing and rendering XML natively (#4252) - Added support for `WAVE_FORMAT_EXTENSIBLE` to the internal wav dexcoder. - Added optional `buffer_size` parameter to `input.alsa` and `output.alsa` (#4243) - Reimplemented audioscrobbler support natively using the more recent protocol (#4250) - Added boolean getter to disable/enable normalization (#4308) Changed: - Make alsa I/O work with buffer size different than liquidsoap internal frame (#4236) - Reimplemented CUE file parser in native liquidsoap script, added support for multiple files and EAC non-compliant extension (#1373, #4330) - Make `"song"` metadata mapping to `"title"` metadata in `input.harbor` disabled when either `"artist"` or `"title"` is also passed. Add a configuration key to disable this mechanism. (#4235, #2676) - `output.icecast` now re-sends the last metadata when connecting to the remote server unless explicitly disabled using the `send_last_metadata_on_connect` option (#3906) - Add full explicit support for `ipv4` vs. `ipv6` resolution in SRT inputs and outputs, add global `settings.srt.prefer_address` and `settings.icecast.prefer_address` (#4317) - Added generic SRT socket get/set API. Added new socket options, including `latency` and `ipv6only`. Fixed: - Fixed request resolution loop when enabling both `autocue` and `replaygain` metadata resolvers (#4245, fixed in #4246) - Fixed `flac` encoding segfault (#4286, #4274) - Fixed source `last_metadata` not being properly updated (#4262) - Convert all ICY (icecast) metadata from `input.http` to `utf8`. - Fixed `inotify` unwatching due to GC cleanup (#4275) - Fixed `delay` initial conditions (#4281) --- # 2.3.0 (2024-11-27) New: - Rewrote the streaming API to work with immutable frame content. This should greatly impact impredictable side-effect of the previous models w.r.t. track marks, content sharing and more. This also impacts multiple operators behavior. Mostly, things should be roughly the same with differences around behaviors related to track marks (`source.on_track` and etc). (#3577) - Added script caching layer for faster script startup time. See: https://www.liquidsoap.info/blog/2024-06-13-a-faster-liquidsoap/ for details (#3924, #3949, #3959 and #3977) - Rewrote the clock/streaming loop layer. This prepares our streaming system to support multicore when the OCaml compiler is mature enough to allow it. Clocks are now attached to sources via their `clock` methods. Returned value is a stripped down `clock` variable. Users can use the `clock` function to retrieve the full methods, e.g. `s = sine(); c = clock(s.clock)`. This value has advanced functions for clock control such as `start`/`stop`, `ticks` and `self_sync` to check for `self-sync`. (#3781) - Allow frames duration shorter than one video frames, typically values under `0.04s`. Smaller frames means less latency and memory consumption at the expense of a higher CPU usage (#3607) - Change default frame duration to `0.02s` (#4033) - Optimized runtime (#3927, #3928, #3919) - Added NDI output support (#4181) - Added `finally` to execute code regardless of whether or not an exception is raised (see: #3895 for more details). - Added support for Spinitron submission API (#4158) - Removed gstreamer support. Gstreamer's architecture was never a good fit for us and created a huge maintenance and debugging burden and it had been marked as deprecated for a while. Most, if not all of its features should be available using `ffmpeg`. (#4036) - Removed `taglib` support. It is superseded by the internal `ocaml-metadata` module and taglib, with its dependency on the C++ runtime library, has been causing issues with binary builds portability and crashes with the (not yet supported) OCaml 5 compiler. (#4087) - Added `video.canvas` to make it possible to position video elements independently of the rendered video size ([#3656](https://github.com/savonet/liquidsoap/pull/3656), [blog post](https://www.liquidsoap.info/blog/2024-02-10-video-canvas-and-ai/)) - Added cover manager from an original code by @vitoyucepi (#3651) - Added non-interleaved API to `%ffmpeg` encoder, enabled by default when only one stream is encoded. - Allow trailing commas in record definition (#3300). - Added `metadata.getter.source.float` (#3356). - BREAKING: Added `duration` and `ticks` to metadata available when computing HLS segment names (#4135) - Added optional `main_playlist_writer` to `output.file.hls` and derivated operator (#3484) - Added `is_nan`, `is_infinite`, `ceil`, `floor`, `sign` and `round` (#3407) - Added `%track.drop` to the `%ffmpeg` encoder to allow partial encoding of a source's available tracks (#3480) - Added `let { foo? } = ...` pattern matching (#3481) - Added `metadata.replaygain` method to extract unified replay gain value from metadata (#3438). - Added `metadata.parse.amplify` to manually parse amplify override metadata. - Added `compute` parameter to `file.replaygain` to control gain calculation (#3438). - Added `compute` parameter to `enable_replaygain_metadata` to control replay gain calculation (#3438). - Added `copy:` protocol (#3506) - Added `file.touch`. - Added support for sqlite databases (#3575). - Added `string.of_int` and `string.spaces`. - Added `list.assoc.nullable`. - Added `source.cue` (#3620). - Added `string.chars` (#4111) - Added atomic file write operations. - Added new `macos_say` speech synthesis protocol. Make it the default implementation for the `say:` protocol on `macos`. - Added `settings.request.timeout` to set the request timeout globally. Changed: - Reimplemented `request.once`, `single` and more using `source.dynamic`. Removed experiment flag on `source.dynamic`. The operator is considered stable enough to define advanced sources but the user should be careful when using it. - Mute SDL startup messages (#2913). - `int` can optionally raises an error when passing `nan` or `infinity`, `int(infinity)` now returns `max_int` and `int(-infinity)` returns `min_int`. (#3407) - Made default font a setting (#3507) - Changed internal metadata format to be immutable (#3297). - Removed `source.dump` and `source.drop` in favor of safer `request.dump` and `request.drop`. `source.{dump, drop}` can still be implemented manually when needed and with the proper knowledge of what's going on. - Allow a getter for the offset of `on_offset` and dropped the metadata mechanism for updating it (#3355). - `string.length` and `string.sub` now default to `utf8` encoding (#4109) - Disable output paging when `TERM` environment variable is not set. - Allow running as `root` user inside `docker` container by default (#3406). - Run `check_next` before playlist's requests resolutions (#3625) - Set `force` to `true` by default in `file.copy` to make operator behave as expected. - BREAKING: Float comparison now follows the expected specs, in particular: `nan == x` is always `false` and `nan != x` is always `true`. Use `float.is_nan` to test if a float is `nan`. - BREAKING: `replaygain` no longer takes `ebu_r128` parameter (#3438). - BREAKING: assume `replaygain_track_gain` always stores volume in _dB_ (#3438). - BREAKING: protocols can now check for nested static uri. Typically, this means that requests for an uri of the form: `annotate:key="value",...:/path/to/file.mp3` is now considered infallible if `/path/to/file.mp3` can be decoded. - Added `parents` option of `file.mkdir` (#3600, #3601). - Added `forced_major_collections` record field to the result of `runtime.gc.stat()` and `runtime.gc.quick_stat()` (#3783). - Changed the port for the built-in Prometheus exporter to `9599` (#3801). - Set `segments_overheader` in HLS outputs to disable segments cleanup altogether. - Added support for caching LV2 and LADSPA plugins (#3959). - Pulseaudio input and output now restart on pulseaudio errors (#4174). Fixed: - Fixed type generalization on values returned from function applications. Most notably, this should help with HTTP endpoint registration (#3303, fixed in #4030) --- # 2.2.5 (2024-05-01) (Mayday!) New: - Added `enable_autocue_metadata` and `autocue:` protocol to automatically compute cue points and crossfade parameters (#3753, #3811, @RM-FM and @Moonbase59) - Added various ffmpeg timestamps when exporting ffmpeg metadata from filters. - Added `db_levels` method to `blank.*` sources (#3790) - Added `excluded_metadata_resolvers` to `request.create` to make it possible to selectively disable specific metadata resolvers when resolving requests. - Normalized expected API from `autocue`, allow multiple implementation and adapt `cross`/`crossfade` to work with it out of the box with workaround for short tracks. - Added private and swapped memory reporting when compiled with `mem_usage`. - Added priorities to metadata deocoders, allows finer-control of metadata overriding. (#3887) Changed: - Allow to disable `http.*` url normalization. Add warning when url normalization changes the url (#3789) - Add `namespace` and optional source IDs to `mix`. Fixed: - Prevent request metadata from overriding root metadata (#3813) - Fixed `source.drop` and `source.dump` clock initialization. - Fixed bogus report of non-monotonous PTS content when using raw ffmpeg content. - Fixed streaming errors when disconnecting `input.harbor`. - Fixed issues with rendered id3v2 frame that contain binary data (#3817) - Fixed memory leaks with SRT listen socket polling callbacks. - Fixed `%ffmpeg` copy muxer logic with some audio/video streams (#3840) - Fixed `duration` metadata calculation in the presence of `cue_in`/`cue_out` metadata. --- # 2.2.4 (2024-02-04) New: - Added support for `id3v2` metadata in `output.*.hls` when using `%mp3`, `%shine` or `%fdkaac` encoders (#3604) - Added option to set preferred address class (`ipv4`, `ipv6` or system default) when resolving hostnames in http transports and `output.icecast` - Added `self_sync` option to `input.srt` to accommodate for streams in file mode (#3684) - Added `curve` parameter to fade functions and `liq_fade_{in,skip,out}_curve` metadata override (#3691) - Added `delay` parameter to fade functions to make it possible to add delay before fade happens. Add `liq_fade_{in,skip,out}_delay` metadata override. - Added `single_track` option to allow `sequence` to play each source until they are unavailable while keeping track marks. Changed: - `cue_cut` operator has been removed. Cueing mechanisms have been moved to underlying file-based sources. See migration notes for more details. Fixed: - Fix pop/click at the end of fade out/in (#3318) - Fix audio/video synchronization issues when decoding live streams using ffmpeg. - Fix issues with TLS connecting clients not being properly timed out (#3598) - Make sure reconnection errors are router through the regulat `on_error` callback in `output.icecast` (#3635) - Fixed discontinuity count after a restart in HLS outputs. - Fixed file header logic when reopening in `output.file` (#3675) - Fixed memory leaks when using dynamically created sources (`input.harbor`, `input.ffmpeg`, SRT sources and `request.dynamic`) - Fixed invalid array fill in `add` (#3678) - Fixed deadlock when connecting to a non-SSL icecast using the TLS transport (#3681) - Fixed crash when closing external process (#3685) --- # 2.2.2 (2023-11-02) New: - Added `string.escape.html` (#3418, @ghostnumber7) - Add support for getters in arguments of `blank.detect` (#3452). - Allow float in source content type annotation so that it possible to write: `source(audio=pcm(5.1))` Changed: - Trim urls in `input.ffmpeg` by default. Disable using `trim_url=false` (#3424) - Automatically add HLS-specific ffmpeg parameters to `%ffmpeg` encoder (#3483) - BREAKING: default `on_fail` removed on `playlist` (#3479) Fixed: - Allow `channel_layout` argument in ffmpeg encoder to set the number of channels. - Improved support for unitary minus, fix runtime call of optional methods (#3498) - Fixed `map.metadata` mutating existing metadata. - Fixed reloading loop in playlists with invalid files (#3479) - Fixed main HLS playlist codecs when using `mpegts` (#3483) - Fixed pop/clicks in crossfade and source with caching (#3318) - Fixed pop/clicks when resampling using `libsamplerate` (#3429) - Fixed gstreamer compilation. Remember that gstreamer features are DEPRECATED! (#3459) - Fixed html character escaping in `interactive.harbor` (#3418, @ghostnumber7) - Fixed icecast not reconnecting after erroring out while closing connection in some circumstances (#3427) - Fixed parse-only mode (#3423) - Fixed ffmpeg decoding failing on files with unknown codecs. - Fixed a crash due to `wait_until` timestamp being in the past when using `posix-time2` - Make sure that temporary files are always cleaned up in HLS outputs (#3493) --- # 2.2.1 (2023-09-05) Changed: - BREAKING: on HLS outputs, `on_file_change` events are now `"created"`, `"updated"` and `"deleted"`, to better reflect the new atomic file operations (#3284) - Added `compact` argument to the `http.response.json` function. `http.response.json` will produce minified JSON by default. Added a newline symbol to the end of the JSON data produced by `http.response.json`. (#3299) - Bumped internal ogg decoder to make sure that it is used over the ffmpeg decoder whenever possible. FFmpeg has issues with metadata in chained streams which needs to be fixed upstream. Unfortunately, `input.http` can only use the ffmpeg decoder at the moment. - Cleanup `output.file` encoding and file handling logic (#3328) - Added `ratio` to `source.{dump,drop}` to make it possible to control its CPU peaks. - Enhanced clock error reporting (#3317) Fixed: - Fixed slow memory leak in muxer operator (#3372, #3181, #3334) - Fixed discontinuity logic error in HLS outputs after a restart. - Fixed HTTP response status in `output.harbor` (#3255) - Make sure main HLS playlist is regenerated after being unlinked (#3275) - Fixed hard crash on icecast disconnection errors. - Fix `output.harbor` encoder header when encoding with `%ogg`, `%vorbis` and etc. (#3276) - Fixed quality argument parsing in ffmpeg encoders (#3267) - Make all HLS file write atomic (#3284) - Allow seek and cue operators to work with muxed sources using a single underlying source (#3252) - Fixed export of cover art metadata (#3279) - Remove use of `stereo:` protocol in `say:` protocol: this is now handled automatically by the decoder and generates latency via high CPU usage peak. - Fixed `output.file` reopening with flac encoding (#3328) --- # 2.2.0 (2023-07-21) New: - Added support for less memory hungry audio formats, namely `pcm_s16` and `pcm_f32` (#3008) - Added support for native osc library (#2426, #2480). - SRT: added support for passphrase, pbkeylen, streamid, added native type for srt sockets with methods, moved stats to socket methods, added `socket()` method on srt input/outputs (#2556) - HLS: Added support for ID3 in-stream metadata (#3154) and custom tags (#2898). - Added support for FLAC metadata (#2952) - Added support for YAML parsing and rendering (#2855) - Added support for the proprietary shared stereotool library (#2953) - Added TLS support via `ocaml-tls` (#3074) - Added `video.align`. - Added `string.index`. - Added support for ffmpeg decoder parameters to allow decoding of raw PCM stream and file (#3066) - Added support for unit interactive variables: those call a handler when their value is set. - Added support for id3v2 `v2.2.0` frames and pictures. - Added `track.audio.defer` to be used to buffer large amount of audio data (#3136) - Added `runtime.locale.force` to force the system's locale (#3231) - Added support for customizable, optimized `jemalloc` memory allocator (#3170) - Added `source.drop` to animate a source as fast as possible.. - Added in house replaygain computation: - `source.replaygain.compute` to compute replaygain of a source - `file.replaygain` to compute the replaygain of a file - Added support for ImageLib to decode images. - Added support for completion in emacs based on company (#2652). - Added syntactic sugar for record spread: `let {foo, gni, ..y} = x` and `y = { foo = 123, gni = "aabb", ...x}` (#2737) - Added `file.{copy, move}` (#2771) - Detect functions defining multiple arguments with the same label (#2823). - Added `null.map`. - References of type `'a` are now objects of type `(()->'a).{set : ('a) -> unit}`. This means that you should use `x()` instead of `!x` in order to get the value of a reference. Setting a reference can be done both by `x.set(v)` and `x := v`, which is still supported as a notation (#2881). - Added `ref.make` and `ref.map`. - Added `video.board`, `video.graph`, `video.info` (#2886). - Added the `pico2wave` protocol in order to perform speech synthesis using [Pico TTS](https://github.com/naggety/picotts) (#2934). - Added `settings.protocol.gtts.lang` to be able to select `gtts`' language, added `settings.protocol.gtts.options` to be able to add any other option (#3182) - Added `settings.protocol.pico2wave.lang` to be able to select `pico2wav` language (#3182) - Added `"metadata_url"` to the default list of exported metadata (#2946) - Added log colors! - Added `list.filter_map` and `list.flatten`. - Added `medialib` in order to store metadata of files in a folder and query them (#3115). - Added `--unsafe` option (#3113). This makes the startup much faster but disables some guarantees (and might even make the script crash...). - Added `string.split.first` (#3146). - Added `string.getter.single` (#3125). Changed: - Switched to `dune` for building the binary and libraries. - Changed `cry` to be a required dependency. - Changed default character encoding in `output.harbor`, `output.icecast` `output.shoutcast` to `UTF-8` (#2704) - BREAKING: all `timeout` settings and parameters are now `float` values and in seconds (#2809) - BREAKING: in `output.{shoutcast,icecast}`: - Old `icy_metadata` renamed to `send_icy_metadata` and changed to a nullable `bool`. `null` means guess. - New `icy_metadata` now returns a list of metadata to send with ICY updates. - Added `icy_song` argument to generate default `"song"` metadata for ICY updates. Defaults to ` - ` when available, otherwise `artist` or `title` if available, otherwise `null`, meaning don't add the metadata. - Cleanup, removed parameters that were irrelevant to each operator, i.e. `icy_id` in `output.icecast` and etc. - Make `mount` mandatory and `name` nullable. Use `mount` as `name` when `name` is `null`. - `reopen_on_error` and `reopen_on_metadata` in `output.file` and related operators are now callbacks to allow dynamic handling. - Added `reopen` method to `output.file`. - Added support for a Javascript build an interpreter. - Removed support for `%define` variables, superseded by support for actual variables in encoders. - Cancel pending append when skipping current track on `append` source. - Errors now report proper stack trace via their `trace` method, making it possible to programmatically point to file, line and character offsets of each step in the error call trace (#2712) - Reimplemented `harbor` http handler API to be more flexible. Added a new node/express-like registration and middleware API (#2599). - Switched default persistence for cross and fade-related overrides to follow documented behavior. By default, `"liq_fade_out"`, `"liq_fade_skip"`, `"liq_fade_in"`, `"liq_cross_duration"` and `"liq_fade_type"` now all reset on new tracks.

Changed: - Send data in-memory in `http.{post,put}.file` when input data is already in memory. This allows to use plain `Content-Length` instead of `chunked` transfer encoding in these case, though `libcurl` seems to always prefer `chunked` encoding for `put` requests. - Better error message when an encoder is not available on windows (#2665) - Create output directory in HLS outputs when it does not exist using newly introduced `perms` permission argument (#2725) - Removed `restart_on_error` argument on `output.url` and added `restart_delay` which implements a delayed restart.

For instance, you can now write ``` s = (single("file.mp4") : source(video(width=300,height=200))) ``` in order to force the decoding of a file to be performed at the 300×200 resolution (#2212). - Video images are now _canvas_, which means that they do not directly contain the images, but are constituted of multiple images placed at various positions. This should make much more efficient operations such as making videos from multiple ones, adding a logo, etc. (#2207) - `output.youtube.live` renamed `output.youtube.live.rtmp`, remove `bitrate` and `quality` arguments and added a single encoder argument to allow stream copy and more. - `source.on_metadata` and `source.on_track` now return a source as this was the case in previous versions, and associated handlers are triggered only when the returned source is pulled (#2103). - Made `streams_info` parameter of `output.file.hls` a record (#2173). - Disable scrolling by default in `video.add_text`.

It brings several important fixes, but also some nice novelties. The most outstanding difference concerns `output.icecast()`: its restart and `restart_delay` parameters are gone, replaced by a new `on_stop` handler which is called on every error (failed connection or disconnection) and returns the new restart delay. The `on_error` handler receives a string describing the error which enables user-friendly reporting, adaptative delays, etc. Note that `on_error` defaults to `fun(_)->3`. which is equivalent to having restart=true, restart_delay=3. in previous versions, NOT the same as the former restart=false default. As a result, liquidsoap won't fail to startup if an initial connection attempt fails. Fixes: - LS-532,527: avoid freeze after errors in streaming threads or source initialization routines - LS-542: race condition in `playlist*()` breaking randomness - LS-489: double expiration lead to illegal queue length and freeze of request-based sources - Avoid multiple simultaneous reloading in `playlist*()`, thanks to Fabio Costa for his help on this one! - Pass charset information to icecast server to avoid encoding bugs - LS-555: timeout for icecast connection attempts - LS-559: permanent stop after disconnection on Ogg streams - LS-565: efficient and crash-free error handling in `input.http/harbor()` when the input stream has an invalid number of channels - LS-431: proper handling of duration in `blank()` avoids abusive empty tracks - LS-556: rework conversion operators, optimizations used to be unsafe & broken - LS-574: silent MIDI synthesis operators - LS-396: `drop*()`'s types reflect that they don't support variable arities - LS-442: allow comments not terminated by newline at end of file New: - `on_error` handler in `output.icecast()`, see above - New msg param in %mp3 for marking frame headers, defaults to version string - `output.file()`: new `on_close` parameter, may be used to write exact duration - %mp3.vbr/abr for variable bitrate MP3, %mp3 is now a synonym of %mp3.cbr - MP3 encoders now support ID3v2 tags - `input.http()`: new "status" command - LS-556: `mux_mono()` for adding a single audio channel into a stream - `video.add_text()` using libgd (gd4o) for environments without X Dependency on graphics can be disabled (to work around erreneous detection) - script language: add infix operator mod (patch by Fabio Costa) - `delay()` now has an "initial" parameter - LS-557: "server.timeout" setting can now be disabled by setting it to -1 - LS-532: `source.init()` for selective init with a way to handle errors, plus settings "clock.allow_streaming_errors" and "init.force_stat" (or --force-start on the command line) for easing dynamic uses of liquidsoap Enhancements: - Panic crash to avoid frozen liquidsoap after duppy crashes - Text-to-speech: festival and sox are now only runtime dependencies - LS-475,516: better support for dynamic URL change in `input.http()` - LS-484: display user-friendly error messages in interactive mode - LS-308: use seconds internally in request sources, avoid overflow and display more user-friendly debug messages - Cleanup `visu.volume()` and `video.vis_volume()` - LS-573: replace " " by "\_" in identifiers to make them valid in the server - Script syntax: unary minus now usable without parenthesis after semicolon - Two generic queues by default, to avoid deadlocks in advanced situations - Documentation, build & install system, etc. # 1.0.0 beta3 (05-08-2011) - Feature: Added `of_json` to parse json data. Depends on json-wheel. - Feature: Added file.exists and is_directory. - Feature: Added timeout options for: telnet, harbor (server), input.icecast - Enhancement: finer-grained timeout detection for `input.harbor` and `input.http` - Fix: deadlock when disconnecting harbor users through server/telnet command. - Fix: dynlink detection in native mode with old versions of ocaml - Fix: deadlock when an exception is raised during startup while the clock is owned by a source (e.g. `input.alsa`). See LS-527 for more details. # 1.0.0 beta2.1 (07-07-2011) - Fix: `playlist.safe()` was unusable in beta2, as a side effect of removing duplicate "timeout" parameter in `playlist()`. - Minor enhancements to documentation, settings and reference. # 1.0.0 beta2 (04-07-2011) This release introduces lots of fixes and cleanup, but also some new features. Major novelties: support for fast seeking and cue points, FLAC and improved AAC+ support, introduction of the liquidsoap yellowpages "flows", plugin support and improved messages for scripting errors Compatibility warning: `insert_metadata` has changed, and `clock.assign_new()` should be used instead of `clock()` to avoid some of the new static checks Decoders: - New support for seeking and fast computation of durations in most formats - New decoders: FLAC (native & Ogg) and images using Camlimages - Fixes in Ogg decoding: LS-515 (loss of data) and LS-537 (segfault). - Fix LS-337: periodical failures when decoding AAC(+) streams - AAC(+): use new ocaml-faad with builtin mp4ff, easier to build - New detection mechanism mixing extensions and MIME types (when available), with corresponding settings `decoder.file_extensions.<format>` and `decoder.mime_types.<format>`. - Decoder order can be user-defined thanks to new settings "decoder.file_decoders", "decoder.stream_decoders" and "decoder.metadata_decoders". - Indicate which decoder is used in the "decoder" metadata - More helpful log for various errors - Fix segfault with SdlImage image decoder Encoders: - New FLAC encoders %flac (native) and %ogg(%flac) - New AAC+ 2.0 and vo-aacenc - New settings to theora: keyframes make files much smaller! - New settings for WAV encoding: headerless, samplesize. - Fix segfaults with ocaml-aacplus - Enhancement LS-441: filter metadata before encoding, based on the "encoder.metadata.export" setting. - Rework infrastructure of encoded outputs to fit all formats, outputs and styles of metadata handling, file reopening (#386) Harbor: - New: `output.harbor()` which acts as a mini icecast server, accepting listeners directly. Encoding is shared among users, and is only performed when needed. - New: ability to register HTTP GET/POST handlers to create simpler web services, using `harbor.http.register/remove()`. - Make all settings local: port, user and password can be set independently for each `input.harbor()` source - New: "metadata_charset" and "icy_metadata_charset" in `input.harbor()` - Fix: race condition possibly leading to abusive "source taken" (LS-500) Icecast: - Add support for streaming native flac, only works when streaming to `input.harbor()`, not supported by actual Icecast servers - Fix bugs in ICY protocol support (header parsing, user name) - Use ICY metadata updates when streaming AAC(+) - New: "encoding" parameter for `output.icecast()`, used for recoding metadata Defaults to "latin1" with shoutcast servers - New: `icy.update_metadata()` function for manual updates - Enhance default "song" metadata, avoiding " - " when unnecessary (#467) Input/output: - New experimental `input.v4l/v4l2()` for webcams - New experimental `input/output.udp()` for unchecked UDP streaming, available with most formats (at your own risk) - Restore `output.pipe.external()`, now called `output.external()` - New parameters for most outputs and inputs (start, on_start, on_stop, fallible); cleanup and uniformize implementations (LS-365) - New ALSA settings alsa.alsa_buffer, alsa.buffer_length and alsa.periods Setting periods=0 allows to not attempt to set the number periods, which is impossible on some devices - New preference order in `input/output.preferred()`: pulseaudio, portaudio, oss, alsa, ao, dummy Operators: - New: support for cue points with `cue_cut()` - Change `insert.metadata()` which is now more script friendly, returning an insertion function rather than register a server command. The old functionality is available as `server.insert_metadata()`. - New: `rms()` operator for getting RMS of a stream, and `server.rms()` which makes this information available as a server command. - New: `track_sensitive` mode for blank detection operators - New: `playlist.reloadable()` for playing a list once, with a command for restarting it. - Remove `id.*()` which can be replaced by type annotations Scripting API: - New: OSC support through `osc.bool()`, `osc.float()` and `osc.float_pair()` - New: JSON export `json_of()` - New: `http.get()` and `http.post()` - New: `url.encode/decode()`, `base64.encode/decode()` - New: `string.recode()` for charset conversions using camomile - New: `notify_metadata()` and `osd_metadata()`, suitable for use with `on_track()` and `on_metadata()` - New: `request.metadata()` for getting a request's metadata - New: `string.length()` - Enhance `log_clocks()` with parameter for delaying startup - Enhance `get_clock_status()` with "uptime" reference time Server interface: - Print the playlist's URI when calling `<playlist>.uri` without an argument. - Enhance `<queue>.ignore` now works also in the primary queue - New command for changing the URL of an `input.http()`, ref #466. The command is `<id>.url` and it needs a restart (`<id>.stop`, then start) to take effect. - Fixed double registration of server commands which resulted in broken "help" command (LS-521) Script language: - Option "-i" doesn't show types for pervasives anymore - Pretty printing of types (LS-474) with indentation, also used in the documentation - Enhanced type errors (LS-459): no more traces, only the relevant part of types is displayed, plus a few special friendly messages. - Enhanced static checks (LS-123) thanks to the introduction of the `active_source` subtype, for unused variables and ignored values This should avoid common errors, help troubleshooting If needed, advanced users can work around errors using --check-lib and --errors-as-warnings General: - Do not attempt to install "daemon" files if user/group have not been set, unless forced using "make INSTALL_DAEMON= install" - Fix several core "source protocol" bugs, causing assert failures and other crashes: LS-460 (source becomes not ready without operator knowing) #403 (information about being ready is not precise enough) - Fix incorrect image accesses (LS-430) by introducing a safer VFrame API Applies to most video operators ( `video.fade()`, `video.text()`, effects...) - Cleanup resource (de)allocation, which is becoming critical with dynamic reconfigurations (e.g., dynamic output creation, `source.dynamic()`) Enforce that server commands are always deallocated (LS-495) Attempt to stop sources when initialization fails, so they cleanup as much as possible (LS-503) Avoid deadlocks upon crashes in IoRing-based operators Share code for stoppable feeding threads, use it in `input.harbor()` Avoid useless initialization of SDL systems - Dynamic loading of lame and aacplus libraries, making it possible to ship them as separate binary packages. This is particularly useless for non-free libraries and for those that depend on X (e.g., SDL) which is often undesirable on servers - Support for separate compilation of most optional features as plugins Use `--enable-<feature>-dynamic-plugin` in ./configure and --dynamic-plugins-dir in liquidsoap - Better Win32 support, more version checks, separate compilation of C files and compliance with Debian's OCaml standards - Externalize many audio and video functions in the new ocaml-mm library Factorize and optimize various conversions - Rewrite harbor and server code using the new Duppy monad, introducing camlp4 into the build system - New regression tests (make test) - More user-friendly exception printing - Avoid problems preventing backtrace printing Miscellaneous: - Update liguidsoap, make microphone input optional (LS-496) - Do not crash upon charset-recoding failures [LS-473] - Fix in `source.dynamic()`: missing source re-selection [LS-354] - Avoid deadlock on startup in daemon mode [LS-229] - Fixes in LADSPA and SDL causing early freezing of Frame parameters. - Fullscreen mode for `output.sdl()` - Fix: SIGPIPE used to cause crashes (LS-53,LS-287) - Fix: `video.volume()` could crash upon some end-of-track situationos - Fix: properly escape filenames in external file duration methods - Rework timeout management for various sockets (notably icecast & harbor) Set nodelay, remove `TCP_*TIMEOUT` [LS-508,LS-509] # 1.0.0 beta1 (06-09-2010) This beta version introduces two major new features: heterogeneous stream types and clocks. New: - Different sources can carry different types of content. - Encoding formats have been introduced to help infer stream content types. This brings static checking for bounds in encoding parameters. - Introduce conversions between stream contents (mono, stereo, drop audio, video, etc) and muxing. - Allow explicit type annotations in scripts. - Introduce clocks, cleanly allowing for the coexistence of different time flows, and avoiding inconsistencies that can result from it. Soundcard I/O and cross-based operators notably make use of it. - Remove root.sync, replaced by attaching a source s to clock(sync=false,s). - Enable dynamic source creation and `source.shutdown()`. - Extend and adapt MIDI and video operators. - Introduce purely metadata streams (audio=video=midi=0 channels) and metadata stream decoder. - Support WAV streams in `input.http/harbor()`. - Introduce static image decoder using SDL image. - Remove bound of request identifies (RID). - Experimental: `source.dynamic()` for advanced dangerous hacking. - Make path relative to script in `%include "PATH"`, and introduce `%include <...>` where path is relative to liquidsoap library directory. - Add `channels_matrix` parameter to `output.ao()`. - Add `on_(dis)connect` hooks in `input.harbor()`. Cleanup and fixes: - Lots of cleanup and fixes as with all major code rewriting. - Optimize video and stabilize it a little bit... still not perfect. - Rewrite stream and file decoding API, as well as file format detection. - Enhance shutdown and error message reporting, notably for icecast and request-based sources. - Avoid quasi-infinite loop in failed request resolving. # 0.9.3 (04-09-2010) This release is a bugfix of the latest snapshot (0.9.2). It will be the last bugfix before 1.0. Bugs fixed: - Add "audio/mpegurl" to the list of mime-type for basic playlist parsing. - Decode arguments passed to `input.harbor`. - Use Camomile framework to try to recode arguments and user/password passed to `input.harbor`. - Support Theora 1.1 API via ocaml-theora 0.2.0. - Fixed `input.lastfm`. - Fixed SDL output. - Allow magic file type detection to follow symlinks. # 0.9.2 (29-10-2009) This release is a SNAPSHOT of upcoming features. It also contains several important bugfixes. As a snapshot, it contains experimental or unpolished features, and also breaks compatibility with previous versions. You should in particular notice the two "New" items below: - `random(strict=true)` is now called `rotate()`; - request sources (`playlists`, `request.*`) have a new queuing behavior, check the doc (request-sources.html) or revert to conservative=true. Bugs fixed: - Ogg encoder now muxes pages according to their ending time. - Support "ogg/audio" and "ogg/video" mime types for HTTP ogg streams. - Changed external encoder's "restart_encoder" to the more relevant "restart_on_new_track". Added optional "restart_after_delay" to restart the encoder after some delay. Also completely rewrite stop mechanism. Stop operation now waits for the encoding process to finish, allowing proper restart_on_new_track like for ogg encoded data. - Factorized buffered I/O code. Also added a blocking API, which avoids "no available frame" and "reader not ready" messages and audio glitches. It enforces that `root.sync` be deactivated for these sources, such that synchronization is done by the source. (#203) - Factorized file decoding code. - Fixed reversed order when parsing playlists using `playlist.parse()`. - Avoid bad crashes when resources lack, e.g. no more memory. - Tighten and enforce the inter-source protocol. - All outputs: fix the autostart server command. With the former code, a modification of the autostart parameter was only taken into account one start/stop cycle later. - `on_blank()`: fix a bug that prevented the first call to on_noise. - Fixed estimated remaining samples on ogg files, fixes issues with operators relying on this value, in particular `crossfade()` and request-based sources when operating in non-conservative mode. - Fixed socket descriptor leak in `input.http`. (#318) - Fixed deadlock at init when an exception was raised at wake_up phase. (#319) - Fix `delay()` which could sometimes incorrectly declare itself ready, and thus try to get some data from its unavailable input source. - Bug in queue duration estimation led to infinite feeding of the queue, until all request IDs are taken. - Several fixes enforcing clean (non-deadlocking) sleep/shutdown. New: - The operator `rotate()` replaces random(strict=true), and `random()` does not have a strict parameter anymore. - Switch to new behaviour in request-based sources. Use conservative=true to get to the old behaviour. - `on_blank()`: provide an `on_noise` handler. - `playlist*()`: add server commands for reloading the playlist and changing its URI. - Fallible outputs: all outputs now have a fallible mode, in which they accept fallible sources, and automatically start/stop when the child fails to stream. - EXPERIMENTAL ogg/dirac encoding support. - `output.*.aacplus()`: native outputs encoding in AAC+ using ocaml-aacplus. - Switched to a custom implementation of the various shout protocols. It notably allows arbitrary content-type settings which enables AAC+ streaming. Enabled wrappers for external encoders for AAC+ format aacplusenc (#220 and #136). Also added custom IRC, AIM and ICQ headers to shoutcast wrappers (#192). - Harbor now supports Shoutcast/ICY headers properly. This allows in particular the use of any supported data format for the source client. - Harbor sources now also consider "song" field when updating metadata. - Added built-in support for m4a audio files and metadata. Made external support optional through enable_faad. - Added optional resampling for output.external operators (#273). - Added optional host and port parameters for audioscrobbling submissions. Allows to use alternate systems, such as libre.fm of jamendo's compatibility API. Added nowplaying submission, and various wrappers, including a full submission process (now playing at beginning, submit some times before the end). - New variables in the script language: `liquidsoap.version` and `configure.{libdir,pidfile,logdir}`. - Added built-in support for replay_gain, through the replay_gain protocol (enabled by default) and the replay gain metadata resolver (to be enabled using `enable_replaygain_metadata()`). (#103 & #317) - Reverse DNS operations can be disabled using settings keys `server.telnet.reverse_dns` and `harbor.reverse_dns`. Experimental: - MIDI: file decoding, synthesis, virtual keyboard. Removed: - RTP input and output. - Removed decoders using ocaml-natty. Slow, unmaintained and superseded by the mplayer decoder. # 0.9.1 (18-06-2009) Bugs fixed: - Fixed request task not ending properly for request-driven sources (playlist, request.queue, request.equeue). Fixes a problem reported when reloading an empty playlist multiple times. (#269) - Fixed math.h usage in rgb_c.c. - Fixed append operator. (#284) - Fixed OSS compilation for non-linux systems. - Disconnect idle harbor sources after timeout has expired. Thanks to Roman Savrulin for reporting and fixing ! - Taglib metadata resolver is only used on files decoded by the MP3 decoder. New: - Get a node's striping status when stripping blank with `strip_blank` (#260). - `on_connect` function for `input.harbor` now receives the list of headers given by the connected source (#266). - Added `on_end` operator, to execute a handler when a track ends. - Added estimated remaining time in the queue length for request-driven sources (`request.{equeue,queue}`, `playlist`). This allows these sources to prepare less files in advance. In particular, primary queue may only contain the file currently played. Default behaviour has been set to the old behaviour, and a conservative option has been added to switch to the new behaviour. New behavivour will be the default for the next release. fixes #169, references #146 # 0.9.0 (01-03-2009) Bugs fixed: - Fixed byte swapping function. - Fixed unix server socket failure (#160). - Fixed mp3 audio glitches when decoding files with picture id3v2 tags using ocaml-mad (#162). - Fixed liquidsoap crash on weird telnet and harbor input (#164). - Fixed `request.queue()` not considering initial queue on wake-up (#196). - Fixed source leak in `append()`. - Fixed `after_output` propagation in the transitions of switches (#208). - Fixed compilation for ocaml 3.11 (#216). - Fixed (again) Vorbis mono output (#211). - Avoid crashing on broken symlinks when parsing directories (#154). - Use random temporary file in liGuidsoap. - Fixed liGuidsoap to use the (not so) new metadata field initial_uri. - Fix bugs in the life cycle (sleep/wake_up) of queued request sources, which made `say_metadata` unfunctional. - Remove buggy unbuffered `{input,output}.jack`. (#231) - Fixed audio information sent to icecast. (#226) - Fixed global reset starting inactive sources. (#227) - Fixed shoutcast source initial answer in harbor. (#254) - Fixed frame and metadata duplication in cross operators. (#257) - Fixed several sources (outputs, external streams) that were not going to sleep correctly. Changes: - Warning: `interactive_float()` is now `interactive.float()`. New: - Compatible with OCaml 3.09. - Faster shutdown. - Rewrote ogg decoding, for files and streams. - Support for ogg skeletons, currently only used for theora. - Cleanup icecast class hierarchy and restart mechanism, especially with respect to the encoder. - Support for breaks and metadata in generators. As a result, `input.http()` and `input.harbor()` now fully support them. See new_track_on_metadata parameters there. - Switch operators (fallback,random and switch) can now replay the metadata of a source that has been left in the middle of a track. - New `force_mime` parameter for `input.http()`. - New `insert_missing` parameter for `append()`. - Multi-line strings in liq scripts, with a caml-like syntax. - Slight modification of the scripting syntax, handling unary minus. - Added `user_agent` parameter for `input.http` and `input.lastfm` - Added speex support for files and HTTP streams. - Added EXPERIMENTAL support for AU, AIFF and NSV mp3 audio files using ocaml-natty. - Added "prefix" parameter to the playlist operators.

Fixes #157 - Added "primary_queue" and "secondary_queue" commands to request.queue and request.equeue sources. Also set the metadata "queue" to either "primary" or "secondary" for each request in the queue. Documented it too. - Insert latest metadata for a node of a switch source when switching back to it in a middle of a track. - Added a 'conservative' parameter to cross, smilar to the one in smartcross. Internal: - Enhanced liqi documentation parser to build the website. # 0.3.7 (03-06-2008) Bugs fixed: - Now works on FreeBSD and hopefully other unices that are stricter than Linux about Mutex usage. - `input.http()` now has a `bind_address` parameter. - Harbor socket now has a timeout for lost connections. - `smartcross()` is now more compliant with the inter-sources protocol, fixes several "get frame didn't change the buffer" bugs. - Ogg packeting bugs. - Buffering policy in `input.http/harbor()`. - No "." in IDs and labels. - Resources: FD leaks, useless threads (threads leaks?) in `input.http()`. - `fade.out()` used to run into infinite loops when the delay was 0. New: - New documentation system and website. - Self-documenting server with a more helpful "help" command. - Moved to duppy: less threads, lighter load, and an configurable scheduler. - Moved to Taglib for more reliable access to MP3 metadata. - MIME types, notably for playlists and MP3 files. - New Jack support. The old one has been renamed to `in/output.jack.legacy()`. - Harbor: per-mount passwords and the stop command to kick a source client. - Official Last.FM client. - Metadata is no more punctual but interval-based, which suppresses some surprising behaviours. - Perfected daemon behaviour. - All `output.file.*()` now have the features that used to be only in `output.file.vorbis()`, notable re-opening.

Now, `rewrite_metadata()` is a simple specialization of `map_metadata()`, written in utils.liq. - Dynamic amplification factor in `amplify()`, e.g. useful for replay gain. - Lots of new functions in the scripting API: for lists, requests, system interaction, shutdown, command-line parsing, scripted server commands, etc. As always: - code cleanup, style, etc. # 0.3.6 (17-12-2007) Bugfix release: - Close Http socket - Add http socket timeout - Close playlist file after reading its content - Fix http redirect support for lastfm files - Fix file open leak in camomile support - Fix playlist uri ending with "/" # 0.3.5 (08-11-2007) Bugfix release: - Fixed #57: scpls and mpegurl playlist parsing - Fixed #46: Late cross-scripts bindings # 0.3.4 (25-09-2007) Notation: "-" stands for a change, "+" for an addition. - Language - Support for polymorphism, subtyping and basic ad-hoc polymorphism, which allows a much simpler API, notably for maths and serialization. * Added `interactive_*()` for mutable values. - The right syntax for settings is now set("var", value) and can be used anywhere in the scripts. - The volume parameters of most operators are now in dB. - Many builtin functions added. - Nicer type error messages. - Sources - Added `input.lastfm()` to relay last.fm streams. - Added `input.harbor()` to received Icecast2 source streams. - Added `noise()` to generate white noise * Reimplemented playlist support, added various xml and text formats. * Added mpd protocol to find files using mpd. - Operators - New effects: `compress()`, `flanger()`, `pan()`. - New filters: `filter.fir.*()`, `filter.iir.*()`, `filter.biquad.*()`, `comb()`. - Added support for LADSPA effects. - Added `eat_blank()` to remove blanks. - Outputs - Added non-default restart option for `output.icecast.*()`. - Added the possibility to tweak some settings at runtime. - Split `output.icecast.vorbis()` into `output.icecast.vorbis.*()` to distinguish between encoding modes -- and similarly for output.file.vorbis and mp3. - Better handling of Icecast disconnections. - IO - Added portaudio support. * Jack support is now somewhat working. - As usual, lots of bug fixes, careful polishing & much more... # 0.3.3 (06-06-2007) - Major cleanup of the core stream representation; moved to float arrays, removing several back-and-forth conversions and enhancing the perfs a lot; reviewed all sources and operators, made many minor enhancements btw. - Lots of sound processing operators: compand, compress, normalize, pitch, bpm, soundtouch, saw, square, etc. Add more shapes to `fade.*()`. - New track processing operators: insert_metadata, on_track. - Smart cross: allows to select a transition based on the volumes around the end-of-track. - Support for AAC encoding/decoding. - Several fixes to output.icecast.mp3 in order to support shoutcast servers. - Automatic format recognition for `input.http()`, support for playlists. - OSS I/O. - Unbuffered ALSA I/O for low latency. - Server interface via UNIX domain sockets. - Better output.file.vorbis with support for re-opening the file, appending, interpolate strftime format codes, etc. - Add pre-processing and math primitives to the language, new `_[_]` notation for `assoc()`, ruby-style anti-quotation `("..#{..}..")`, `add_timeout()`, `execute()`, `log()`... - Ability to tweak the internal PCM stream format. - Classify sources and operators in categories for more structured doc. - Started a few visualization operators, text and graphics based. - Several bug fixes: request leaks, sine frequency, switch, etc. # 0.3.2 (16-03-2007) - New portable output to speakers using `libao()`. - Updated liGuidsoap to use it until ALSA gets enhanced. - Implemented a decent estimation of the remaining time in a track. - Added the `cross()` operator allowing cross-fading. - Generalized `say_metadata()` into `append()` and `prepend()`. - Per-track settings for `cross()`, `fade.*()`, `prepend()` and `append()` using requests' metadatas. - Implemented `input.http.mp3()`, including support for icy metadata. - New `pipe()` operator which allows one to filter the raw audio through an external program. However, sox and other common tools aren't suitable for that because they don't flush their output often enough. - New `on_blank()` operator for calling a callback on excessive blanks. - Restart outputs on insane latencies. - Type checkings for settings. - Setting for not starting the internal telnet server. - Now handles old and new versions of Camomile correctly. - Internal fixes and polishing (switches' cached selection, empty tracks..) # 0.3.1 (17-11-2006) - More standards-compliant tarball - Generate doc with locally built liquidsoap - Try to cope with ill-formed mp3 - Updated for newer versions of Camomile - So-called "strict" random-mode # 0.3.0 (27-08-2006) - Many minor and major fixes at every level! - Conversion of metadata to UTF8. - Got rid of too many threads by scheduling all download tasks in a single thread, and handling all of the server's clients in another single thread. - Simplified the time interval syntax and integrated it to the script language. - New protocol: Wget for FTP, HTTP and HTTPS. - Ability to define a new protocol from the script, typically using an external app/script for resolution, such as bubble. - Ability to use an external app/script for dynamically creating requests. - New `on_metadata` operator for performing arbitrary actions (typically a call to an external script) when metadata packets occur in a stream. - MP3 encoding, to file or shout. - API renamings and simplification. - Supports transition, as functions of type (source,source) -> source in all switching operators: schedule, random, fallback. - Restart icecast2 outputs on failures. - Major changes to the scripting language which is more uniform and flexible, has functions, a helpful (?) type inference, and a simple Ruby-like syntax. - Timing constraints and synchronization are managed by Root in a centralized way, no more by the many outputs which need it. - Audio decoding is no more based on file extensions, but on the existence of a valid decoder. - Added the equeue operators which allows interactive building of playlists, supporting insertion and moving of queued requests -- queue only allows you to push requests and cancel queued requests. - A Python-Gtk GUI for controlling operators, or more specifically as a console for creating your live show -- to be updated, still unstable. - Alsa input and output. - Blank detection, automatically skips on too long blanks, or strip them. - Http ogg/vorbis relay, the way to relay live shows. - Interactive mixer. - The request system was mostly rewritten to really fulfill its specification. - The server is no more associated to the queue operator but is now something external, in which all operators can plug commands. This much more logical design lead to many more interactive controls. The syntax of command outputs was also simplified for easier automated processing. - Dynamic loading of plugins. - Outputs are now operators. It makes it possible to output different streams in a single instance of Liquidsoap, which RadioPi needed. As a consequence we removed the restriction that one source must have at most one father, without any extra burden for the user. # 0.2.0 (20-04-2005) - Proper initial release. # 0.1.0 (2004) - Release for academic demonstration, not functional. ������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/CITATION.cff�����������������������������������������������������������������������0000664�0000000�0000000�00000001455�14773033502�0015573�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������cff-version: 1.2.0 message: "In order to reference this software, please cite it as below." abstract: "Liquidsoap is a powerful and flexible language for describing your streams.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. <one line to give the program's name and a brief idea of what it does.> Copyright (C) <year> <name of author> This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. <signature of Ty Coon>, 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. ������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/Makefile���������������������������������������������������������������������������0000664�0000000�0000000�00000000060�14773033502�0015330�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������all: build build install clean test: @dune $@ ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/README�����������������������������������������������������������������������������0000777�0000000�0000000�00000000000�14773033502�0016026�2README.md�������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/README.md��������������������������������������������������������������������������0000664�0000000�0000000�00000020047�14773033502�0015156�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Liquidsoap Liquidsoap is a swiss-army knife for multimedia streaming, notably used for netradios and webtvs. It has tons of features, it's free and it's open-source! Liquidsoap is a powerful and flexible language for describing your streams. It offers a rich collection of operators that you can combine to create and transform streams. Liquidsoap is very light and easy to use, in the Unix tradition of simple strong components working together.

Versions with only bugfix version changes **should be** compatible Please note that liquidsoap is a complex framework with a lot of operators and advanced implementations. For this reason, it is possible that a bugfix actually fixes the behavior of an operator the way it was intended to be and may break scripts that previously relied on incorrect implementations. Therefore, we **strongly** recommend maintaining a `staging` environment that makes it possible to test new versions before using them in production. In this context, the semantic versioning above should guide you in knowing how much scrutiny you should put into a new release before validating it in your staging environment. ### Assets Release assets are provided at: https://github.com/savonet/liquidsoap/releases. Published, versioned releases are available using their published tag, i.e. `vx.y.z`. We also provide **rolling releases**. A rolling release is a snapshot of a current, unpublished release. It can be a future stable release or a future bugfix release for a given major/minor version. For both types of releases, we reserve the right to update, delete and add assets to the release at any time. If you are looking for permanent links to release assets, you should grab them from https://github.com/savonet/liquidsoap-release-assets/releases, which reflects all our releases but whose artifacts are never modified/deleted. ## Tooling | | | | ----------- | -------------------------------------------------------------------------------------------------------------------------------------------------- | | Formatting | [liquidsoap-prettier](https://github.com/savonet/liquidsoap-prettier) | | VSCode | [vscode-liquidsoap](https://marketplace.visualstudio.com/items?itemName=savonet.vscode-liquidsoap) | | Tree Sitter | [tree-sitter-liquidsoap](https://github.com/savonet/tree-sitter-liquidsoap), [nvim-treesitter](https://github.com/nvim-treesitter/nvim-treesitter) | | CodeMirror | [codemirror-lang-liquidsoap](https://github.com/savonet/codemirror-lang-liquidsoap) | | Playground | [https://www.liquidsoap.info/try/](https://www.liquidsoap.info/try/) | ## Documentation HTML documentation is available on our [website](http://liquidsoap.info) We also have written _the Liquidsoap book_ which is [available online](http://www.liquidsoap.info/book/book.pdf) and in [physical version](https://www.amazon.com/dp/B095PVTYR3). ## Contributing Contributions are more than welcome: you can submit [issues](https://github.com/savonet/liquidsoap/issues) if you find some, or contribute to the code through [pull requests](https://github.com/savonet/liquidsoap/pulls).

This should run the tests and prepare all the assets. [] Update the versioned dependencies in `liquidsoap.opam`, release pending dependent bindings (see below on how to publish to `opam`). [] Update copyright years in headers and check that all files have license headers. [] Fill-in CHANGES, with the release date. Opam packages ------------- Packages can be published to opam using `opam publish`. Make sure to check upstream for improvement made on the package files before sending the updates. `opam` versioning for version suffix is: `x.y.z~suffix`. It is not compatible with liquidsoap's `configure` based version detection so make sure to avoid depending on version-suffixed packages. �������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/ROADMAP.md�������������������������������������������������������������������������0000664�0000000�0000000�00000005140�14773033502�0015301�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������## Backlog - Explore new compiled backends - Update the book - Romain to document new internals - Write article for ICFP - support for ffmpeg subtitles - use OCaml 5 (after it has matured) - use native (as in native.liq) implementation of switch (based on source.dynamic) - reimplement video.tile in native liq - rework buffer.adaptative - use source getters for switch in order to be able to play two tracks ever day (#2880) ### Maybe TODO: - remove requests and use sources instead everywhere (a request is a source with one track [or more]) (weak maybe) - Precise scheduling with queue.push, etc.: we could make the track available at some precise time if requests were sources... - this may allow stuff like `append` more easily - Add support for modules, load minimal API by default - Simple mechanism to tell source how much data will be expected in advance (e.g. 10s with cross) to allow automatic buffer management. - Redefine switch-based transitions. ### Nice to have - refine video support in order to have next liquidshop running on Liquidsoap (dogfooding) - use row variables for methods, using Garrigue's _Simple Type Inference for Structural Polymorphism_ - can we reimplement something like [melt](https://www.mltframework.org/)? - support for WebRTC using WHIP / WHEP - support decorations on a subtitle image track - make bindings to pipewire to support webcams and screensharing ## For 2.2 ### Done - ~~Separate language core (#2397)~~ - ~~Online version (#2397)~~ - ~~Available at: https://www.liquidsoap.info/try/~~ - ~~Needs some cleanup, definition of a minimal JS library.~~ - ~~Switch to `dune`~~wh - ~~Separate standard library (in pure liq)~~ - ~~support for multi-track audio~~ - ~~live switch with ffmpeg encoded content~~ - ~~deprecate "!" and ":=" in favor of x.get / x.set~~ - ~~switch to immutable content for metadata~~ - ~~Add script tooling, prettier etc.~~ - ~~switch to immutable content for frames (#2364)~~ - ~~frame should be changed to extensible arrays (a bit like `Strings`) instead of filling a buffer~~ - ~~take the opportunity to change the handling of track boundaries (currently boundary = we have a partial fill, which has quite messy corner cases)~~ ## For 2.3 ### Done: - ~~Rewrite streaming loop~~ - ~~rewrite the clock system~~ - ~~the code is unreadable and overengineered ⇒ simplify it~~ - we want to get rid of the assumption clock = thread (Feasible but problem with OCaml 5) - ~~Optimize runtime: start time, typing and memory usage~~ - ~~javascrtipt/browser support using [WebCodecs](https://developer.mozilla.org/en-US/docs/Web/API/WebCodecs_API)!~~ ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/SECURITY.md������������������������������������������������������������������������0000664�0000000�0000000�00000002446�14773033502�0015473�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Security Policy ## Supported Versions Currently, we provide active support for the following versions of liquidsoap: | Version | Supported | | ------- | ------------------ | | `2.2.x` | :white_check_mark: | | `2.1.x` | :x: | | `2.0.x` | :x: | | `1.4.x` | :x: | | `< 1.4` | :x: | If you find a vulnerability in an unsupported version, please tell us.

You will also need to adjust the playout gain per track (ReplayGain). In that case you would better have a music library queried by Liquidsoap. In this section we'll do this with [Beets](http://beets.io/). Beets holds your music catalog, cleans tracks' tags before importing, can compute each track's ReplayGain, and most importantly has a command-line interface we can leverage from Liquidsoap. The following examples may also inspire you to integrate another library or your own scripts. After installing Beets, enable the `random` plug-in (see [Beets documentation on plug-ins](https://beets.readthedocs.io/en/stable/plugins/index.html#using-plugins)). To enable gain normalization, install and configure the [`replaygain`](https://beets.readthedocs.io/en/stable/plugins/replaygain.html) plug-in. To easily add single tracks to you library, you might also be interested in the [drop2beets](https://github.com/martinkirch/drop2beets#drop2beets) plug-in. The following examples suppose you defined a `BEET` constant, which contains the complete path to your `beet` executable (on UNIX systems, find it with `which beet`). For example: ``` BEET = "/home/radio/.local/bin/beet" ``` Before creating a Liquidsoap source, let's see why Beets queries are interesting for a radio. ## Beets queries Queries are parameters that you usually provide to the `beet ls` command : Beets will find matching tracks. The `random` plug-in works the same, except that it returns only one track matching the query (see [the plug-in's documentation](https://beets.readthedocs.io/en/stable/plugins/random.html)). Once your library is imported, you can try the following queries on the command line by typing `beet ls [query]` or `beet random [query]`. To test quickly, add the `-t 60` option to `beet random` so it will select an hour worth of tracks matching your query. Without selectors, queries search in a track’s title, artist, album name, album artist, genre and comments. Typing an artist name or a complete title usually match the exact track, and you could do a lovely playlist just by querying `love`. But in a radio you'll usually query on other fields. You can select tracks by genre with the `genre:` selector. Be careful that `genre:Rock` also matches `Indie Rock`, `Punk Rock`, etc. To select songs having english lyrics, use `language:eng`. Or pick 80s songs with `year:1980..1990`. Beets also holds internal meta-data, like `added`: the date and time when you imported each song. You can use it to query tracks inserted over the past month with `added:-1m..`. Or you can query track imported more than a year ago with `added:..-1y`. Beets also lets you [set your own tags](https://beets.readthedocs.io/en/stable/guides/advanced.html#store-any-data-you-like). You can use the `info` plug-in to see everything Beets knows about title(s) matching a query by typing `beet info -l [query]`. See also [the Beets' documentation](https://beets.readthedocs.io/en/stable/reference/query.html) for more details on queries operators. All these options should allow you to create both general and specialized Liquidsoap sources. ## A source querying each next track from Beets As of Liquidsoap 2.x we can create a function that creates a dynamic source, given its `id` and a Beet query. We rely on `request.dynamic` to call `beet random` (with `-f '$path'` option so beets only returns the matching track's path) every time the source must prepare a new track: ```{.liquidsoap include="beets-source.liq" from="BEGIN" to="END"} ``` Note that - `query` can be empty, it will match all tracks in the library. - we set `retry_delay` to a second, to avoid looping on `beet` calls if something goes wrong. - The final type hint (`:source`) will avoid false typing errors when the source is integrated in complex operators. ## Applying ReplayGain When the [`replaygain` plug-in](https://beets.readthedocs.io/en/stable/plugins/replaygain.html) is enabled, all tracks will have an additional metadata field called `replaygain_track_gain`. Check that Beet is configured to [write ID3 tags](https://beets.readthedocs.io/en/stable/reference/config.html#importer-options) so Liquidsoap will be able to read this metadata - your Beet configuration should include something like: ``` import: write: yes ``` Then we only need to add `amplify` to our source creation function. In the example below we also add `blank.eat`, to automatically cut silence at the beginning or end of tracks. ```{.liquidsoap include="beets-amplify.liq" from="BEGIN"} ``` This is the recommended Beets integration ; such source will provide music continuously, at a regular volume. ## Beets as a requests protocol If you're queueing tracks with `request.queue`, you may prefer to integrate Beets as a protocol. In that case, the list of paths returned by `beet random -f '$path'` fits directly what's needed by protocol resolution: ```{.liquidsoap include="beets-protocol.liq" from="BEGIN"} ``` Once this is done, you can push a beets query from [the telnet server](server.html): if you created `request.queue(id="userrequested")`, the server command `userrequested.push beets:All along the watchtower` will push the Jimi Hendrix's song. With this method, you can benefit from replay gain metadata too, by wrapping the recipient queue in an `amplify` operator, like ```liquidsoap userrequested = amplify(override="replaygain_track_gain", 1.0, request.queue(id="userrequested") ) ``` ���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/blank.md���������������������������������������������������������������0000664�0000000�0000000�00000002657�14773033502�0017536�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Blank detection [Liquidsoap](index.html) has three operators for dealing with blanks. On GeekRadio, we play many files, some of which include bonus tracks, which means that they end with a very long blank and then a little extra music. It's annoying to get that on air. The `blank.skip` operator skips the current track when a too long blank is detected, which avoids that. The typical usage is simple: ```liquidsoap # Wrap it with a blank skipper s = blank.skip(s) ``` At [RadioPi](http://www.radiopi.org/) they have another problem: sometimes they have technical problems, and while they think they are doing a live show, they're making noise only in the studio, while only blank is on air; sometimes, the staff has so much fun (or is it something else ?) doing live shows that they leave at the end of the show without thinking to turn off the live, and the listeners get some silence again. To avoid that problem we made the `blank.strip` operators which hides the stream when it's too blank (i.e. declare it as unavailable), which perfectly suits the typical setup used for live shows: ```{.liquidsoap include="blank-sorry.liq"} ``` If you don't get the difference between these two operators, you should learn more about liquidsoap's notion of [source](sources.html). Finally, if you need to do some custom action when there's too much blank, we have `blank.detect`: ```{.liquidsoap include="blank-detect.liq" from="BEGIN" to="END"} ``` ���������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/book.md����������������������������������������������������������������0000664�0000000�0000000�00000001014�14773033502�0017363�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# The Liquidsoap book Together with the release of Liquidsoap 2.0, we have written _the Liquidsoap book_ which covers in details the language and the process of building a radio.

The software relies on an up-to date OCaml compiler, as well as a bunch of OCaml modules and, for most of them, corresponding C library dependencies. Our recommended way of installing liquidsoap is via [opam](http://opam.ocaml.org/). `opam` can take care of installing the correct OCaml compiler, optional and required dependencies as well as system-specific package dependencies. The `opam` method is described in details in the [documentation](doc/content/install.md). We recommend that any interested user head over to this link to install the software via `opam`. The remainder of this document describes how to compile liquidsoap locally for developers. ## Overview Liquidsoap is compiled using [dune](https://dune.readthedocs.io/en/stable/), which is the most popular OCaml build system at the moment. `dune` is tightly integrated with `opam` so, even if you are installing from source using `dune`, `opam` remains an important tool. Generally speaking, compiling from source may require the latest version of the liquidsoap code as well as its dependencies. Some of its dependencies are optional and can be ignored at first and some are not. Keep in mind that, although `opam` is generally aware of required minimal version for dependencies, `dune` is not. If a dependency is outdated, `dune` compilation will simply fail, at which point your may have to figure out if you need to update a dependency. Each branch of liquidsoap is compiled using [github actions](https://github.com/savonet/liquidsoap/actions). When trying to build a specific branch, if the CI passes with it then, most likely, you are missing a dependency, or it is not the latest version. ## `opam` pinning `opam` pinning is a mechanism to update `opam` with the latest version of a package, even before it is published to the official opam repository. This is the easiest way to update a dependency to its latest version. You can pin directly from a local git repository checkout: ```shell git clone https://github.com/savonet/ocaml-metadata.git cd ocaml-metadata opam pin -ny . ``` You can also pin directly using a git url: ```shell opam pin -ny git+https://github.com/savonet/ocaml-cry ``` See `opam pin --help` for more details about the available options. ## Dependencies The best way to figure out what dependencies are required or optional and their versions is to use the latest `opam` package. Since `liquidsoap` development is using `dune` and `opam`, the dependencies are kept in sync via the local liquidsoap opam package(s) and this serves as the de-facto list of dependencies and their versions. First, you should pin the latest liquidsoap code: ```shell opam pin -ny git+https://github.com/savonet/liquidsoap ``` Then, ask `opam` to list all the dependencies for `liquidsoap`: ```shell opam info liquidsoap opam info liquidsoap-lang ``` This should give you a (long!) list of all dependencies. Then, you can query `opam` to see what each dependency does. This is particularly useful for optional dependencies on `liquidsoap-core` which provide opt-in features. For instance `opam info soundtouch` will let you know that this package provides functions for changing pitch and timestretching audio data. Lastly, there are two types of dependencies: - Dependencies maintained by us - Dependencies not maintained by us For dependencies not maintained by us, most of the time, we rely on the latest published version. Very rarely should you have to fetch/pin the latest version of these dependencies. For dependencies maintained by us, we may break their API during our development cycle, and you maybe have to fetch/pin the latest version when compiling the latest `liquidsoap` code. You may also have to check out a specific branch when compiling `liquidsoap` from a specific development branch when the changes in the liquidsoap code are paired with changes in one of our dependencies. Typically, this happens a lof with the `ffmpeg` binding. ## Environment variables When compiling Liquidsoap from source, certain environment variables can be set to control the build process and customize the build configuration. Here’s a brief overview of the relevant environment variables and their purposes: - `IS_SNAPSHOT`: Set this variable to indicate whether you are building a snapshot version of Liquidsoap. It affects the version suffix and whether the Git commit is displayed. - `LIQ_GIT_SHA`: Override Git commit hash (SHA) if the build system cannot automatically extract it from the repository. - `LIQ_VERSION`: Override the displayed version of Liquidsoap. - `LIQUIDSOAP_ENABLE_BUILD_CONFIG`: Determines whether the build configuration details are displayed during the build process. - `LIQUIDSOAP_BUILD_TARGET`: Controls the runtime lookup paths for Liquidsoap components. - Set to `default`: Uses paths detected in the OPAM switch directory. - Set to `standalone`: Uses paths relative to the binary location, ideal for self-contained deployments. - Set to `posix`: Configures paths to standard system directories. ## Compiling Once you have all dependencies installed, you should be able to compile via: ```shell dune build ``` If an error occurs, you may need to see if you need to update a dependency. Hopefully, with a short iteration of this cycle, you will end up with a successful build! Once you have a successful build, you can also use the top-level `liquidsoap` script. This script builds the latest code and executes it right away. It works as if you were calling the `liquidsoap` binary after installing it: ```shell ./liquidsoap -h output.ao ``` From here, you can start changing code, testing script etc. Happy hacking! ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/clocks.md��������������������������������������������������������������0000664�0000000�0000000�00000031057�14773033502�0017721�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Clocks In the [quickstart](quick_start.html) and in the introduction to liquidsoap [sources](sources.html), we have described a simple world in which sources communicate with each other, creating and transforming data that composes multimedia streams. In this simple view, all sources produce data at the same rate, animated by a single clock: at every cycle of the clock, a fixed amount of data is produced. While this simple picture is useful to get a fair idea of what's going on in liquidsoap, the full picture is more complex: in fact, a streaming system might involve _multiple clocks_, or in other words several time flows. It is only in very particular cases that liquidsoap scripts need to mention clocks explicitly. Otherwise, you won't even notice how many clocks are involved in your setup: indeed, liquidsoap can figure out the clocks by itself, much like it infers types. Nevertheless, there will sometimes be cases where your script cannot be assigned clocks in a correct way, in which case liquidsoap will complain. For that reason, every user should eventually get a minimum understanding of clocks. In the following, we first describe why we need clocks. Then we go through the possible errors that any user might encounter regarding clocks. Finally, we describe how to explicitly use clocks, and show a few striking examples of what can be achieved that way. ## Why multiple clocks The first reason is **external** to liquidsoap: there is simply not a unique notion of time in the real world. Your computer has an internal clock which indicates a slightly different time than your watch or another computer's clock. Moreover, when communicating with a remote computer, network latency causes extra time distortions. Even within a single computer there are several clocks: notably, each soundcard has its own clock, which will tick at a slightly different rate than the main clock of the computer. Since liquidsoap communicates with soundcards and remote computers, it has to take those mismatches into account. There are also some reasons that are purely **internal** to liquidsoap: in order to produce a stream at a given speed, a source might need to obtain data from another source at a different rate. This is obvious for an operator that speeds up or slows down audio (`stretch`). But it also holds more subtly for `cross`, `cross` as well as the derived operators: during the lapse of time where the operator combines data from an end of track with the beginning of the other other, the crossing operator needs twice as much stream data. After ten tracks, with a crossing duration of six seconds, one more minute will have passed for the source compared to the time of the crossing operator. In order to avoid inconsistencies caused by time differences, while maintaining a simple and efficient execution model for its sources, liquidsoap works under the restriction that one source belongs to a unique clock, fixed once for all when the source is created. The graph representation of streaming systems can be adapted into a good representation of what clocks mean. One simply needs to add boxes representing clocks: a source can belong to only one box, and all sources of a box produce streams at the same rate. For example, ```liquidsoap output.icecast(fallback([crossfade(playlist(...)),jingles])) ``` yields the following graph: ![Graph representation with clocks](/assets/img/graph_clocks.png) Here, clock_2 was created specifically for the crossfading operator; the rate of that clock is controlled by that operator, which can hence accelerate it around track changes without any risk of inconsistency. The other clock is simply a CPU-based clock, so that the main stream is produced following the ``real'' time rate. ## Error messages Most of the time you won't have to do anything special about clocks: operators that have special requirements regarding clocks will do what's necessary themselves, and liquidsoap will check that everything is fine. But if the check fails, you'll need to understand the error, which is what this section is for. ### Disjoint clocks On the following example, liquidsoap will issue the fatal error `a source cannot belong to two clocks`: ```liquidsoap s = playlist("~/media/audio") output.alsa(s) # perhaps for monitoring output.icecast(mount="radio.ogg",%vorbis,crossfade(s)) ``` Here, the source `s` is first assigned the ALSA clock, because it is tied to an ALSA output. Then, we attempt to build a `crossfade` over `s`. But this operator requires its source to belong to a dedicated internal clock (because crossfading requires control over the flow of the of the source, to accelerate it around track changes). The error expresses this conflict: `s` must belong at the same time to the ALSA clock and `crossfade`'s clock. ### Nested clocks On the following example, liquidsoap will issue the fatal error `cannot unify two nested clocks`: ```liquidsoap jingles = playlist("jingles.lst") music = rotate([1,10],[jingles,playlist("remote.lst")]) safe = rotate([1,10],[jingles,single("local.ogg")]) q = fallback([crossfade(music),safe]) ``` Let's see what happened. The `rotate` operator, like most operators, operates within a single clock, which means that `jingles` and our two `playlist` instances must belong to the same clock. Similarly, `music` and `safe` must belong to that same clock. When we applied crossfading to `music`, the `crossfade` operator created its own internal clock, call it `cross_clock`, to signify that it needs the ability to accelerate at will the streaming of `music`. So, `music` is attached to `cross_clock`, and all sources built above come along. Finally, we build the fallback, which requires that all of its sources belong to the same clock. In other words, `crossfade(music)` must belong to `cross_clock` just like `safe`. The error message simply says that this is forbidden: the internal clock of our crossfade cannot be its external clock -- otherwise it would not have exclusive control over its internal flow of time. The same error also occurs on `add([crossfade(s),s])`, the simplest example of conflicting time flows, described above. However, you won't find yourself writing this obviously problematic piece of code. On the other hand, one would sometimes like to write things like our first example. The key to the error with our first example is that the same `jingles` source is used in combination with `music` and `safe`. As a result, liquidsoap sees a potentially nasty situation, which indeed could be turned into a real mess by adding just a little more complexity. To obtain the desired effect without requiring illegal clock assignments, it suffices to create two jingle sources, one for each clock: ```liquidsoap music = rotate([1,10],[playlist("jingles.lst"), playlist("remote.lst")]) safe = rotate([1,10],[playlist("jingles.lst"), single("local.ogg")]) q = fallback([crossfade(music),safe]) ``` There is no problem anymore: `music` belongs to `crossfade`'s internal clock, and `crossfade(music)`, `safe` and the `fallback` belong to another clock. ## The clock API There are only a couple of operations dealing explicitly with clocks. The function `clock.assign_new(l)` creates a new clock and assigns it to all sources from the list `l`. For convenience, we also provide a wrapper, `clock(s)` which does the same with a single source instead of a list, and returns that source. With both functions, the new clock will follow (the computer's idea of) real time, unless `sync=false` is passed, in which case it will run as fast as possible. The old (pre-1.0.0) setting `root.sync` is superseded by `clock.assign_new()`. If you want to run an output as fast as your CPU allows, just attach it to a new clock without synchronization: ```liquidsoap clock.assign_new(sync="none",[source]) ``` This will automatically attach the appropriate sources to that clock. Another important use case of this operator is if your script involves multiple sources from the same external clock, typically multiple ALSA input or output from the same sound card or multiple jack input and output. By default (the so-called `clock_safe` mode), liquidsoap will assign a dedicated clock to each of those sources, leading either to an error or forcing the use of an unnecessary `buffer` (see below). Instead, you can allocate each source with `clock_safe=false` and assign them a single clock: ``` s1 = input.jack(clock_safe=false, ...) s2 = input.jack(clock_safe=false, ...) clock.assign_new([s1,s2]) ``` However, you may need to do it for other operators if they are totally unrelated to the first one. The `buffer()` operator can be used to communicate between any two clocks: it takes a source in one clock and builds a source in another. The trick is that it uses a buffer: if one clock happens to run too fast or too slow, the buffer may empty or overflow. Finally, `get_clock_status` provides information on existing clocks and track their respective times: it returns a list containing for each clock a pair `(name,time)` indicating the clock id its current time in _clock cycles_ -- a cycle corresponds to the duration of a frame, which is given in ticks, displayed on startup in the logs. The helper function `log_clocks` built around `get_clock_status` can be used to directly obtain a simple log file, suitable for graphing with gnuplot. Those functions are useful to debug latency issues. ## External clocks: decoupling latencies The first reason to explicitly assign clocks is to precisely handle the various latencies that might occur in your setup. Most input/output operators (ALSA, AO, Jack, OSS, etc) require their own clocks. Indeed, their processing rate is constrained by external sound APIs or by the hardware itself. Sometimes, it is too much of an inconvenience, in which case one can set `clock_safe=false` to allow another clock assignment -- use at your own risk, as this might create bad latency interferences. Currently, `output.icecast` does not require to belong to any particular clock. This allows to stream according to the soundcard's internal clock, like in most other tools: in `output.icecast(%vorbis,mount="live.ogg",input.alsa())`, the ALSA clock will drive the streaming of the soundcard input via icecast. Sometimes, the external factors tied to Icecast output cannot be disregarded: the network may lag. If you stream a soundcard input to Icecast and the network lags, there will be a glitch in the soundcard input -- a long enough lag will cause a disconnection. This might be undesirable, and is certainly disappointing if you are recording a backup of your precious soundcard input using `output.file`: by default it will suffer the same latencies and glitches, while in theory it could be perfect. To fix this you can explicitly separate Icecast (high latency, low quality acceptable) from the backup and soundcard input (low latency, high quality wanted): ```liquidsoap input = input.oss() # Icecast source, with its own clock: icecast_source = mksafe(buffer(input)) clock.assign_new(id="icecast", [icecast_source]) # Output to icecast: output.icecast(%mp3,mount="blah",icecast_source) # File output: output.file( %mp3,{time.string("record-%Y-%m-%d-%H-%M-%S.mp3")}, input) ``` Here, the soundcard input and file output end up in the OSS clock. The icecast output goes to the explicitly created `"icecast"` clock, and a buffer is used to connect it to the soundcard input. Small network lags will be absorbed by the buffer. Important lags and possible disconnections will result in an overflow of the buffer. In any case, the OSS input and file output won't be affected by those latencies, and the recording should be perfect. The Icecast quality is also better with that setup, since small lags are absorbed by the buffer and do not create a glitch in the OSS capture, so that Icecast listeners won't notice the lag at all. ## Internal clocks: exploiting multiple cores Clocks can also be useful even when external factors are not an issue. Indeed, several clocks run in several threads, which creates an opportunity to exploit multiple CPU cores. The story is a bit complex because OCaml has some limitations on exploiting multiple cores, but in many situations most of the computing is done in C code (typically decoding and encoding) so it parallelizes quite well. Typically, if you run several outputs that do not share much (any) code, you can put each of them in a separate clock. For example the following script takes one file and encodes it as MP3 twice. You should run it as `liquidsoap EXPR -- FILE` and observe that it fully exploits two cores: ```liquidsoap def one() s = single(argv(1)) clock.assign_new(sync="none",[s]) output.file(%mp3,"/dev/null",s) end one() one() ``` ���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/complete_case.md�������������������������������������������������������0000664�0000000�0000000�00000003573�14773033502�0021250�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# A complete case analysis We will develop here a more complex example, according to the following specifications: - play different playlists during the day; - play user requests -- done via the telnet server; - insert about 1 jingle every 5 songs; - add one special jingle at the beginning of every hour, mixed on top of the normal stream; - relay live shows as soon as one is available; - and set up several outputs. Once you've managed to describe what you want in such a modular way, you're half the way. More precisely, you should think of a diagram such as the following, through which the audio streams flow, following the arrows. The nodes can modify the stream using some basic operators: switching and mixing in our case. The final nodes, the ends of the paths, are outputs: they are in charge of pulling the data out of the graph and send it to the world. In our case, we only have outputs to icecast, using two different formats. ![Graph for 'radio.liq'](/assets/img/liqgraph.png) Now here is how to write that in [Liquidsoap](index.html). ```{.liquidsoap include="complete-case.liq"} ``` To try this example you need to edit the file names. In order to witness the switch from one playlist to another you can change the time intervals. If it is 16:42, try the intervals `0h-16h45` and `16h45-24h` instead of `6h-22h` and `22h-6h`. To witness the clock jingle, you can ask for it to be played every minute by using the `0s` interval instead of `0m0s`. To try the transition to a live show you need to start a new stream on the `live.ogg` mount of your server. You can send a playlist to it using examples from the [quickstart](quick_start.html). To start a real live show from soundcard input you can use `darkice`, or simply liquidsoap if you have a working ALSA input, with: ```liquidsoap liquidsoap 'output.icecast(%vorbis, \ mount="live.ogg",host="...",password="...",input.alsa())' ``` �������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/cookbook.md������������������������������������������������������������0000664�0000000�0000000�00000034360�14773033502�0020251�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Cookbook The recipes show how to build a source with a particular feature. You can try short snippets by wrapping the code in an `output(..)` operator and passing it directly to liquidsoap: ```liquidsoap liquidsoap -v 'output(recipe)' ``` For longer recipes, you might want to create a short script: ```liquidsoap #!/usr/bin/liquidsoap -v log.file.path := "/tmp/<script>.log" log.stdout := true recipe = # <fill this> output(recipe) ``` See the [quickstart guide](quick_start.html) for more information on how to run [Liquidsoap](index.html), on what is this `output(..)` operator, etc. See also the [ffmpeg cookbook](ffmpeg_cookbook.html) for examples specific to the ffmpeg support. ## Files A source which infinitely repeats the same URI: ```{.liquidsoap include="single.liq"} ``` A source which plays a playlist of requests -- a playlist is a file with an URI per line. ```{.liquidsoap include="playlists.liq" to="END"} ``` When building your stream, you'll often need to make it unfallible. Usually, you achieve that using a fallback switch (see below) with a branch made of a safe `single`. Roughly, a single is safe when it is given a valid local audio file. ## Transcoding [Liquidsoap](index.html) can achieve basic streaming tasks like transcoding with ease. You input any number of "source" streams using `input.http`, and then transcode them to any number of formats / bitrates / etc. The only limitation is your hardware: encoding and decoding are both heavy on CPU. If you want to get the best use of CPUs (multicore, memory footprint etc.) when encoding media with Liquidsoap, we recommend using the `%ffmpeg` encoders. ```{.liquidsoap include="transcoding.liq"} ``` ## Re-encoding a file As a simple example using a fallible output, we shall consider re-encoding a file. We start by building a source that plays our file only once. That source is obviously fallible. We pass it to a file output, which has to be in fallible mode. We also disable the `sync` parameter on the source's clock, to encode the file as quickly as possible. Finally, we use the `on_stop` handler to shutdown liquidsoap when streaming is finished. ```{.liquidsoap include="re-encode.liq"} ``` ## Generating CUE files When making backups of streams in audio files, it can be useful to generate CUE files, which store the times where the various tracks occur along with their metadata (those could then be used later on to split the file for instance). This can be achieved using the `source.cue` operator: ```{.liquidsoap include="source-cue.liq" from="BEGIN" to="END"} ``` which will generate a CUE file of the following form ``` TITLE "My stream" PERFORMER "The performer" FILE "backup.mp3" MP3 TRACK 01 AUDIO TITLE "Title 1" PERFORMER "Artist 1" INDEX 01 00:00:00 TRACK 02 AUDIO TITLE "Title 2" PERFORMER "Artist 2" INDEX 01 01:12:67 ``` ## RTMP server With our [FFmpeg support](ffmpeg.html), it is possible to create a simple RTMP server with no re-encoding: ```{.liquidsoap include="rtmp.liq"} ``` ## Transmitting signal It is possible to send raw PCM signal between two instances using the [FFmpeg encoder](ffmpeg.html). Here's an example using the SRT transport protocol: Sender: ```{.liquidsoap include="srt-sender.liq" from="BEGIN"} ``` Receiver: ```{.liquidsoap include="srt-receiver.liq" to="END"} ``` ## Scheduling ```{.liquidsoap include="fallback.liq" to="END"} ``` ```{.liquidsoap include="scheduling.liq" from="BEGIN" to="END"} ``` ## Generating playlists from a media library In order to store all the metadata of the files in a given directory and use those to generate playlists, you can use the `medialib` operator which takes as argument the directory to index. On first run, it will index all the files of the given folder, which can take some time (you are advised to use the `persistency` parameter in order to specify a file where metadata will be stored to avoid reindexing at each run). The resulting object can then be queried with the `find` method in order to return all files matching the given conditions and thus generate a playlist: ```{.liquidsoap include="medialib.liq"} ``` The parameter of the `find` method follow the following convention: - `artist="XXX"` looks for files where the artist tag is exactly the given one - `artist_contains="XXX"` looks for files where the artist tag contains the given string as substring - `artist_matches="XXX"` looks for files where the artist tag matches the given regular expression (for instance `artist_matches="(a)+.*(b)+"` looks for files where the artist contains an `a` followed by a `b`). The tags for which such parameters are provided are: `artist`, `title`, `album` and `filename` (feel free to ask if you need more). Some numeric tags are also supported: - `year=1999` looks for files where the year is exactly the given one - `year_ge=1999` looks for files where the year at least the given one - `year_lt=1999` looks for files where the year at most the given one The following numeric tags are supported: `bpm`, `year`. If multiple arguments are passed, the function finds files with tags matching the conjunction of the corresponding condition. Finally, if you need more exotic search functions, the argument `predicate` can be used. It takes as argument a _predicate_ which is a function taking the metadata of a file and returning whether the file should be selected. For instance, the following looks for files where the name of the artist is of length 5: ```{.liquidsoap include="medialib-predicate.liq" from="BEGIN" to="END"} ``` The default implementation of `medialib` uses standard Liquidsoap functions and can be pretty expensive in terms of memory. A more efficient implementation is available if you compiled with support for sqlite3 databases. In this case, you can use the `medialib.sqlite` operator as follows: ```{.liquidsoap include="medialib.sqlite.liq"} ``` (we also support more advanced uses of [databases](database.html)). ## Force a file/playlist to be played at least every XX minutes It can be useful to have a special playlist that is played at least every 20 minutes for instance (3 times per hour). You may think of a promotional playlist for instance. Here is the recipe: ```{.liquidsoap include="regular.liq" from="BEGIN" to="END"} ``` Where promotions is a source selecting the file to be promoted. ## Play a jingle at a fixed time Suppose that we have a playlist `jingles` of jingles and we want to play one within the 5 first minutes of every hour, without interrupting the current song. We can think of doing something like ```{.liquidsoap include="fixed-time1.liq" from="BEGIN" to="END"} ``` but the problem is that it is likely to play many jingles. In order to play exactly one jingle, we can use the function `predicate.activates` which detects when a predicate (here `{ 0m-5m }`) becomes true: ```{.liquidsoap include="fixed-time2.liq" from="BEGIN" to="END"} ``` ## Handle special events: mix or switch Add a jingle to your normal source at the beginning of every hour: ```{.liquidsoap include="jingle-hour.liq" from="BEGIN" to="END"} ``` Switch to a live show as soon as one is available. Make the show unavailable when it is silent, and skip tracks from the normal source if they contain too much silence. ```{.liquidsoap include="switch-show.liq" from="BEGIN" to="END"} ``` Without the `track_sensitive=false` the fallback would wait the end of a track to switch to the live. When using the blank detection operators, make sure to fine-tune their `threshold` and `length` (float) parameters. ## Unix interface, dynamic requests Liquidsoap can create a source that uses files provided by the result of the execution of any arbitrary function of your own. This is explained in the documentation for [request-based sources](request_sources.html). For instance, the following snippet defines a source which repeatedly plays the first valid URI in the playlist: ```{.liquidsoap include="request.dynamic.liq" to="END"} ``` Of course a more interesting behaviour is obtained with a more interesting program than `cat`, see [Beets](beet.html) for example. Another way of using an external program is to define a new protocol which uses it to resolve URIs. `protocol.add` takes a protocol name, a function to be used for resolving URIs using that protocol. The function will be given the URI parameter part and the time left for resolving -- though nothing really bad happens if you don't respect it. It usually passes the parameter to an external program ; it is another way to integrate [Beets](beet.html), for example: ```{.liquidsoap include="beets-protocol-short.liq"} ``` When resolving the URI `beets:David Bowie`, liquidsoap will call the function, which will call `beet random -f '$path' David Bowie` which will output the path to a David Bowie song. ## Dynamic input with harbor The operator `input.harbor` allows you to receive a source stream directly inside a running liquidsoap. It starts a listening server on where any Icecast2-compatible source client can connect. When a source is connected, its input if fed to the corresponding source in the script, which becomes available. This can be very useful to relay a live stream without polling the Icecast server for it. An example can be: ```{.liquidsoap include="harbor-dynamic.liq"} ``` This script, when launched, will start a local server, here bound to "0.0.0.0". This means that it will listen on any IP address available on the machine for a connection coming from any IP address. The server will wait for any source stream on mount point "/live" to login. Then if you start a source client and tell it to stream to your server, on port 8080, with password "hackme", the live source will become available and the radio will stream it immediately. ## Play a short silence when transitioning out of `input.harbor` If the live connection is unstable, for instance when streaming through a roaming phone device, it can be interesting to add an extra `5s` of silence when transitioning out of a live `input.harbor` to give the input some chance to reconnect. This can be done with the `append` operator: ```{.liquidsoap include="append-silence.liq" to="END"} ``` ## Dump a stream into segmented files It is sometimes useful (or even legally necessary) to keep a backup of an audio stream. Storing all the stream in one file can be very impractical. In order to save a file per hour in wav format, the following script can be used: ```{.liquidsoap include="dump-hourly.liq" from="BEGIN"} ``` Here, the function `time.string` generates the file name by replacing `%H` by the hour, etc. The fact that it is between curly brackets, i.e. `{time.string(...)}`, ensures that it is re-evaluated each time a new file is created, the changing the file name each time according to the current time. In the following variant we write a new mp3 file each time new metadata is coming from `s`: ```{.liquidsoap include="dump-hourly2.liq" from="BEGIN"} ``` In the two examples we use [string interpolation](language.html) and time literals to generate the output file name. In order to limit the disk space used by this archive, on unix systems we can regularly call `find` to cleanup the folder; if we can to keep 31 days of recording: ```{.liquidsoap include="archive-cleaner.liq"} ``` ## Transitions There are two kinds of transitions. Transitions between two different children of a switch or fallback and transitions between tracks of the same source. ### Switch-based transitions The switch-based operators (`switch`, `fallback` and `random`) support transitions. For every child, you can specify a transition function computing the output stream when moving from one child to another. This function is given two `source` parameters: the child which is about to be left, and the new selected child. The default transition is `fun (a,b) -> b`, it simply relays the new selected child source. One limitation of these transitions, however, is that if the transition happen right at the end of a track, which is the default with `track_sensitive=true`, then there is no more data available for the old source, which makes it impossible to fade it out. If that is what you are expecting, you should look at crossfade-based transitions ### Crossfade-based transitions Crossfade-based transitions are more complex and involve buffering source data in advance to be able to compute a transition where ending and starting track potentially overlap. This does not work with all type of sources since some of them, such as `input.http` may only receive data at real-time rate and cannot be accelerated to buffer their data or else we risk running out of data. We provide a default operator named `cross.simple` transition which may be suitable for most usage. But you can also create your own customized crossfade transitions. This is in particular true if you are expecting crossfade transitions between tracks of your `music` source but not between a `music` track and e.g. some jingles. Here's how to do it in this case: ```{.liquidsoap include="cross.custom.liq" from="BEGIN" to="END"} ``` ## Alsa output delay You can use [Liquidsoap](index.html) to capture and play through alsa with a minimal delay. This particularly useful when you want to run a live show from your computer. You can then directly capture and play audio through external speakers without delay for the DJ ! This configuration is not trivial since it relies on your hardware. Some hardware will allow both recording and playing at the same time, some only one at once, and some none at all.. Those note to configure are what works for us, we don't know if they'll fit all hardware. First launch liquidsoap as a one line program ``` liquidsoap -v --debug 'input.alsa()' ``` Unless you're lucky, the logs are full of lines like the following: ``` Could not set buffer size to 'frame.size' (1920 samples), got 2048. ``` The solution is then to set liquidsoap's internal frame size to this value, which is most likely specific to your hardware. Let's try this script: ```{.liquidsoap include="frame-size.liq"} ``` The setting will be acknowledged in the log as follows: ``` Targeting 'frame.audio.size': 2048 audio samples = 2048 ticks. ``` If everything goes right, you may hear on your output the captured sound without any delay! If you experience problems it might be a good idea to double the value of the frame size. This increases stability, but also latency. ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/crossfade.md�����������������������������������������������������������0000664�0000000�0000000�00000002524�14773033502�0020411�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Crossfade ## Out of the box Liquidsoap provides a default `crossfade` operator out of the box. It is a simple operator that does the work and does it well! Over the years, we have realized that crossfading is a very sensitive topic and that people care a lot about specific details and how well it is done. Since release `2.2.5`, liquidsoap integrates an automated mechanism to compute crossfade transitions that was contributed by our users. If you have the `ffmpeg` bindings enabled, all you should need to do to enable this feature is adding the following to your script: ```liquidsoap enable_autocue_metadata() ``` This uses the default, internal implementation. If you want more control over the automated crossfade parameters, you can check out the external [autocue](https://github.com/Moonbase59/autocue) implementation and its associated documentation. ## Custom crossfades You can also define your own crossfade transitions if you want to be more specific about them! The base `cross` operator accepts a scripted transition function that, according to the average volume level (in dB) computed on the end of the ending track and the beginning of the new one, returns the transition that is desired. You can find its documentation in the [language reference](reference.html). Here's an example: ```{.liquidsoap include="crossfade.liq"} ``` ����������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/custom-path.md���������������������������������������������������������0000664�0000000�0000000�00000004700�14773033502�0020702�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Basics Starting with version `1.0.1`, it is possible to build a liquidsoap binary that can load all its dependencies from any arbitrary path. This is very useful to distribute a liquidsoap bundled binary, independent of the distribution used. You can enable custom path at configure time, by passing the `--enable-custom-path` configuration option. A custom loading path is a directory that contains the following file/directories: - `./camomile`: Camomile shared data. They are usually located in `/usr/(local/)share/camomile` - `./libs`: pervasive scripts. Their are located in `liquidsoap/scripts` in liquidsoap's sources - `./log`: default log directories - `./magic`: directory for magic files. See below for more details. - `./plugins`: default plugins directory (most likely empty) - `./run`: default runtime files directory # Adding liquidsoap binary In order to ship a liquidsoap binary which is independent of the distribution it will be run on, one need to also include its dynamic libraries, except for the most common. The following command may be used to list them: ``` ldd ./liquidsoap | grep usr | cut -d' ' -f 3 ``` Those libraries are usually copied into a `./ld` directory. Then, the `LD_LIBRARY_PATH` is used to point the dynamic loader to this directory. Finally, the `liquidsoap` library is usually added in `./bin/liquidsoap` # Configuration variables In the following, configuration variables may refer to either absolute or relative paths. If referring to a relative path, the path is resolved relatively to the directory where the `liquidsoap` binary is located at. In order to tell liquidsoap where its custom path is located, you need to set the `LIQUIDSOAP_BASE_DIR`. Another important variable is `MAGIC`. It tells liquidsoap where to load the libmagic's definitions and defaults to `../magic/magic.mgc`. Older versions of libmagic may require to use `magic/magic.mime` instead. # Full example For a fully-functional example, you can check our [heroku buildpack](https://github.com/savonet/heroku-buildpack-liquidsoap). Its layout is: ``` ./bin ./bin/liquidsoap ./camomile ./camomile/charmaps (...) ./ld ./ld/libao.so.2 (...) ./libs ./libs/externals.liq (...) ./log ./magic ./magic/magic.mime ./plugins ./run ``` Its configuration variables are set to: ``` LD_LIBRARY_PATH=/path/to/ld LIQUIDSOAP_BASE_DIR=.. MAGIC=../magic/magic.mime ``` As you can see, we use an old version of `libmagic` so we need to load `magic.mime` instead of `magic.mgc`. ����������������������������������������������������������������liquidsoap-2.3.2/doc/content/database.md������������������������������������������������������������0000664�0000000�0000000�00000010565�14773033502�0020210�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Database support Liquidsoap supports SQL databases through the sqlite library. If you build Liquidsoap by yourself, you should install the [SQLite3-OCaml](https://github.com/mmottl/sqlite3-ocaml) library, e.g. with `opam install sqlite3`{.bash}. In order to create or open a database, you should use the `sqlite` function, which takes as argument the file where the database is stored and returns an object whose methods can be used to modify or query the database: ```{.liquidsoap include="sqlite.liq" from="open-begin" to="open-end"} ``` table in the database can then be created by calling the `table.create` method on the object with as arguments the table name (labeled by `table`) and the list of columns specified by pairs consisting of the column name, and its type. Setting the `preserve` argument to `true`{.liquidsoap} allows not creating the table if one already exists under this name. In our example, we want to use our database to store metadata for files so that we create a table named `"metadata"`{.liquidsoap} with columns corresponding to the artist, title, etc.: ```{.liquidsoap include="sqlite.liq" from="create-begin" to="create-end"} ``` Inserting a row is then performed using the `insert` method, which takes as argument the table and a record containing the data for the row: ```{.liquidsoap include="sqlite.liq" from="insert-begin" to="insert-end"} ``` Since the field `filename` is a primary key, it has to be unique (two rows cannot have the same file name), so that inserting two files with the same filename in the database will result in an error. If we want that the second insertion replace the first one, we can pass the `replace=true`{.liquidsoap} argument to the `insert` function. We can query the database with the `select` method. For instance, to obtain all the files whose year is posterior to 2000, we can write ```{.liquidsoap include="sqlite.liq" from="select-begin" to="select-end"} ``` In the case where you want to use strings in your queries, you should always use `sqlite.escape` to properly escape it and avoid injections: ```{.liquidsoap include="sqlite.liq" from="select2-begin" to="select2-end"} ``` The `select` function, returns a list of rows. To each row will correspond a list of pairs strings consisting of - a string: the name of the column, - a nullable string: its value (this is nullable because the contents of a column can be NULL in databases). We could thus extract the filenames from the above queries and use those in order to build a playlist as follows: ```{.liquidsoap include="sqlite.liq" from="play-begin" to="play-end"} ``` This can be read as follows: for each row (by `list.map`{.liquidsoap}), we convert the row to a list of pairs of strings as described above (by calling the `to_list`{.liquidsoap} method), we replace take the field labeled `"filename"`{.liquidsoap} (by `list.assoc`{.liquidsoap}) and take its value, assuming that it is not null (by `null.get`{.liquidsoap}). Since manipulating rows as lists of pairs of strings is not convenient, Liquidsoap offers the possibility to represent them as records with constructions of the form ```liquidsoap let sqlite.row (r : {a : string; b : int}) = row ``` which instructs to parse the row `row`{.liquidsoap} as a record `r` with fields `a` and `b` of respective types `string`{.liquidsoap} and `int`{.liquidsoap}. The above filename extraction is thus more conveniently written as ```{.liquidsoap include="sqlite.liq" from="play2-begin" to="play2-end"} ``` Other useful methods include - `count` to count the number of rows satisfying a condition ```{.liquidsoap include="sqlite.liq" from="count-begin" to="count-end"} ``` - `delete` to delete rows from a table ```{.liquidsoap include="sqlite.liq" from="play-begin" to="play-end"} ``` - `table.drop` to delete tables from the database ```{.liquidsoap include="sqlite.liq" from="drop-begin" to="drop-end"} ``` - `exec` to execute an arbitrary SQL query which does not return anything: ```{.liquidsoap include="sqlite.liq" from="exec-begin" to="exec-end"} ``` - `query` to execute an arbitrary SQL query returning rows ```{.liquidsoap include="sqlite.liq" from="query-begin" to="query-end"} ``` Finally, if your aim is to index file metadata, you might be interested in the `medialib.sqlite`{.liquidsoap} operator which is implemented in the standard library as described above (see the [cookbook](cookbook.html)). �������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/documentation.md�������������������������������������������������������0000664�0000000�0000000�00000011044�14773033502�0021306�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Documentation index **How to use**: Start with the [quickstart](quick_start.html) and make sure you learn [how to find help](help.html).

The following gives an example of this. First some outlines: - This example is meant to create a new source and outputs. It is not easy currently to change a source being streamed - The idea is to create a new output using a telnet/server command. - In order for a Liquidsoap script to run without an active source at startup, it is necessary to include `settings.init.force_start := true` at the start of the script. In this example, we will register a command that dynamically create a new output based on an encoded stream and output it to an arbitrary url, as supported by the ffmpeg copy encoder. This script can be used to create a dynamic restreaming platform. Here's the code: ```{.liquidsoap include="dynamic-source.liq"} ``` After executing this script, you should see two telnet commands: - `restream.start <uri>` - `restream.stop <uri>` which you can use to create/destroy dynamically your sources. ������liquidsoap-2.3.2/doc/content/encoding_formats.md����������������������������������������������������0000664�0000000�0000000�00000021772�14773033502�0021767�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Encoding formats Encoders are used to define formats into which raw sources should be encoded by an output. Syntax for encoder is: `%encoder(parameters...)` or, if you use default parameters, `%encoder`. Please note that not all encoding formats are available at all time. Most of them require optional dependencies. If a format is not available, you should see an error like this: ```shell Error 12: Unsupported encoder: %sine(). You must be missing an optional dependency. ``` In particular, due to limitations with static linking on windows, only the `%ffmpeg` encoder is available with our windows build. However, this encoder provides a lot of codecs and formats, and it is quite likely that it can provide what you need. ## Formats determine the stream content In most liquidsoap scripts, the encoding format determines what kind of data is streamed. The type of an encoding format depends on its parameter. For example, `%mp3` has type `format(audio=pcm(stereo))`. The type of an output like `output.icecast` or `output.file` is something like `(...,format('a),...,source('a))->source('a)`. This means that your source will have to have the same type as your format. For example if you write ```liquidsoap output.file(%mp3,"/tmp/foo.mp3",playlist("~/audio")) ``` then the playlist source will have to stream stereo audio. In the case of audio format, liquidsoap tries its best to convert the format whenever possible. For instance, in the above, liquidsoap will convert mono files from the playlist to stereo files by duplicating the single audio channel in a mono file. Likewise, if the encoder requires mono audio, it will compute the mean of a stereo files. # List of formats and their syntax All parameters are optional, and the parenthesis are not needed when no parameter is passed. In the following default values are shown. As a special case, the keywords `mono` and `stereo` can be used to indicate the number of channels (whether is is passed as an integer or a boolean). ## MP3 Mp3 encoder comes in 3 flavors: - `%mp3` or `%mp3.cbr`: Constant bitrate encoding - `%mp3.vbr`: Variable bitrate, quality-based encoding. - `%mp3.abr`: Average bitrate based encoding. Parameters common to each flavor are: - `stereo=true/false`, `mono=true/false`: Encode stereo or mono data (default: `stereo`). - `stereo_mode`: One of: `"stereo"`, `"joint_stereo"` or `"default"` (default: `"default"`). Default means that the underlying library (`libmp3lame`) will pick the stereo mode based on compression ration and input channels. - `samplerate=44100`: Encoded data samplerate (default: `44100`) - `internal_quality=2`: Lame algorithms internal quality. A value between `0` and `9`, `0` being highest quality and `9` the worst (default: `2`). - `id3v2=true`: Add an `id3v2` tag to encoded data (default: `false`). Parameters for `%mp3` are: - `bitrate`: Encoded data fixed bitrate Parameters for `%mp3.vbr` are: - `quality`: Quality of encoded data; ranges from `0` (highest quality) to `9` (worst quality). Parameters for `%mp3.abr` are: - `bitrate`: Average bitrate - `min_bitrate`: Minimum bitrate - `max_bitrate`: Maximum bitrate - `hard_min`: Enforce minimal bitrate Examples: - Constant `128` kbps bitrate encoding: `%mp3(bitrate=128)` - Variable bitrate with quality `6` and samplerate of `22050` Hz: `%mp3.vbr(quality=7,samplerate=22050)` - Average bitrate with mean of `128` kbps, maximum bitrate `192` kbps and `id3v2` tags: `%mp3.abr(bitrate=128,max_bitrate=192,id3v2=true)` Optionally, liquidsoap can insert a message within mp3 data. You can set its value using the `msg` parameter. Setting it to `""` disables this feature. This is its default value. ## Shine Shine is the fixed-point mp3 encoder. It is useful on architectures without a FPU, such as ARM. It is named `%shine` or `%mp3.fxp` and its parameters are: ```liquidsoap %shine(channels=2,samplerate=44100,bitrate=128) ``` ## WAV ```liquidsoap %wav(stereo=true, channels=2, samplesize=16, header=true, duration=10.) ``` If `header` is `false`, the encoder outputs raw PCM. `duration` is optional and is used to set the WAV length header. Because Liquidsoap encodes a possibly infinite stream, there is no way to know in advance the duration of encoded data. Since WAV header has to be written first, by default its length is set to the maximum possible value. If you know the expected duration of the encoded data and you actually care about the WAV length header then you should use this parameter. ## FFmpeg See detailed [ffmpeg encoders](ffmpeg_encoder.html) article. ## Ogg The following formats can be put together in an Ogg container. The syntax for doing so is `%ogg(x,y,z)` but it is also possible to just write `%vorbis(...)`, for example, instead of `%ogg(%vorbis(...))`. All ogg encoders have a `bytes_per_page` parameter, which can be used to try to limit ogg logical pages size. For instance: ```liquidsoap # Try to limit vorbis pages size to 1024 bytes %vorbis(bytes_per_page=1024) ``` ### Vorbis ```liquidsoap # Variable bitrate %vorbis(samplerate=44100, channels=2, quality=0.3) % Average bitrate %vorbis.abr(samplerate=44100, channels=2, bitrate=128, max_bitrate=192, min_bitrate=64) # Constant bitrate %vorbis.cbr(samplerate=44100, channels=2, bitrate=128) ``` Quality ranges from -0.2 to 1, but quality -0.2 is only available with the aotuv implementation of libvorbis. ### Opus Opus is a lossy audio compression made especially suitable for interactive real-time applications over the Internet. Liquidsoap supports Opus data encapsulated into Ogg streams. The encoder is named `%opus` and its parameters are as follows. Please refer to the [Opus documentation](http://www.opus-codec.org/docs/) for information about their meanings and values. - `vbr`: one of `"none"`, `"constrained"` or `"unconstrained"` - `application`: One of `"audio"`, `"voip"` or `"restricted_lowdelay"` - `complexity`: Integer value between `0` and `10`. - `max_bandwidth`: One of `"narrow_band"`, `"medium_band"`, `"wide_band"`, `"super_wide_band"` or `"full_band"` - `samplerate`: input samplerate. Must be one of: `8000`, `12000`, `16000`, `24000` or `48000` - `frame_size`: encoding frame size, in milliseconds. Must be one of: `2.5`, `5.`, `10.`, `20.`, `40.` or `60.`. - `bitrate`: encoding bitrate, in `kbps`. Must be a value between `5` and `512`. You can also set it to `"auto"`. - `channels`: currently, only `1` or `2` channels are allowed. - `mono`, `stereo`: equivalent to `channels=1` and `channels=2`. - `signal`: one of `"voice"` or `"music"` ### Theora ```liquidsoap %theora(quality=40,width=640,height=480, picture_width=255,picture_height=255, picture_x=0, picture_y=0, aspect_numerator=1, aspect_denominator=1, keyframe_frequency=64, vp3_compatible=false, soft_target=false, buffer_delay=5, speed=0) ``` You can also pass `bitrate=x` explicitly instead of a quality. The default dimensions are liquidsoap's default, from the settings `frame.video.height/width`. ### Speex ```liquidsoap %speex(stereo=false, samplerate=44100, quality=7, mode=wideband, # One of: wideband|narrowband|ultra-wideband frames_per_packet=1, complexity=5) ``` You can also control quality using `abr=x` or `vbr=y`. ### Flac The flac encoding format comes in two flavors: - `%flac` is the native flac format, useful for file output but not for streaming purpose - `%ogg(%flac,...)` is the ogg/flac format, which can be used to broadcast data with icecast The parameters are: ```liquidsoap %flac(samplerate=44100, channels=2, compression=5, bits_per_sample=16) ``` `compression` ranges from 0 to 8 and `bits_per_sample` should be one of: `8`, `16`, `24` or `32`. Please note that `32` bits per sample is currently not supported by the underlying `libflac`. ## FDK-AAC This encoder can do both AAC and AAC+. Its syntax is: ```liquidsoap %fdkaac(channels=2, samplerate=44100, bandwidth="auto", bitrate=64, afterburner=false, aot="mpeg2_he_aac_v2", transmux="adts", sbr_mode=false) ``` Where `aot` is one of: `"mpeg4_aac_lc"`, `"mpeg4_he_aac"`, `"mpeg4_he_aac_v2"`, `"mpeg4_aac_ld"`, `"mpeg4_aac_eld"`, `"mpeg2_aac_lc"`, `"mpeg2_he_aac"` or `"mpeg2_he_aac_v2"` `bandwidth` is one of: `"auto"`, any supported integer value. `transmux` is one of: `"raw"`, `"adif"`, `"adts"`, `"latm"`, `"latm_out_of_band"` or `"loas"`. Bitrate can be either constant by passing: `bitrate=64` or variable: `vbr=<1-5>` You can consult the [Hydrogenaudio knowledge base](http://wiki.hydrogenaud.io/index.php?title=Fraunhofer_FDK_AAC) for more details on configuration values and meanings. ## External encoders For a detailed presentation of external encoders, see [this page](external_encoders.html). ```liquidsoap %external(channels=2,samplerate=44100,header=true, restart_on_crash=false, restart_on_metadata, restart_after_delay=30, process="progname") ``` Only one of `restart_on_metadata` and `restart_after_delay` should be passed. The delay is specified in seconds. The encoding process is mandatory, and can also be passed directly as a string, without `process=`. ������liquidsoap-2.3.2/doc/content/external_decoders.md���������������������������������������������������0000664�0000000�0000000�00000010217�14773033502�0022130�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������## Introduction You can use external programs in liquidsoap to decode audio files. The program must be able to output WAV data to its standard output (`stdout`) and, possibly, read encoded data from its standard input. Please note that this feature is not available under Windows. ## Basic operators External decoders are registered using the `decoder.add` and `decoder.oblivious.add` operators. They are invoked the following way: ### `decoder.add` ```liquidsoap decoder.add(name="my_decoder",description="My custom decoder", test,decoder) ``` `decoder.add` is used for external decoders that can read the encoded data from their standard input (stdin) and write the decoded data as WAV to their standard output (stdout). This operator is recommended because its estimation of the remaining time is better than the estimation done by the decoders registered using `decoder.oblivious.add`. The important parameters are: - `test` is a function used to determine if the file should be decoded by the decoder. Returned values are: - `0`: no decodable audio, - `-1`: decodable audio but number of audio channels unknown, - `x`: fixed number of decodable audio channels. - `decoder` is the string containing the shell command to run to execute the decoding process. ### `decoder.oblivious.add` `decoder.oblivious.add` is very similar to `decoder.add`. The main difference is that the decoding program reads encoded data directly from the local files and not its standard input. Decoders registered using this operator do not have a reliable estimation of the remaining time. You should use `decoder.oblivious.add` only if your decoding program is not able to read the encoded data from its standard input. ```liquidsoap decoder.oblivious.add(name="my_decoder",description="My custom decoder", buffer=5., test,decoder) ``` `decoder.add` is used for external decoders that can read the encoded data from their standard input (stdin) and write the decoded data as WAV to their standard output (stdout). This operator is recommended because its estimation of the remaining time is better than the estimation done by the decoders registered using `decoder.oblivious.add`. The important parameters are: - `test` is a function used to determine if the file should be decoded by the decoder. Returned values are: - `0`: no decodable audio, - `-1`: decodable audio but number of audio channels unknown, - `x`: fixed number of decodable audio channels. - `decoder` is a function that receives the name of the file that should be decoded and returns a string containing the shell command to run to execute the decoding process. ### `decoder.metadata.add` You may also register new metadata resolvers using the `decoder.metadata.add` operator. It is invoked the following way: `decoder.metadata.add(format,resolver)`, where: - `format` is the name of the resolved format. It is only informative. - `resolver` is a function `f` that returns a list of metadata of the form: `(label, value)`. It is invoked the following way: `f(format=name,file)`, where: - `format` contains the name of the format, as returned by the decoder that accepted to decode the file. `f` may return immediately if this is not an expected value. - `file` is the name of the file to decode. ## Wrappers On top of the basic operators, wrappers have been written for some common decoders. This includes the `flac` and `faad` decoders, by default. All the operators are defined in `externals.liq`. ### The FLAC decoder The flac decoder uses the `flac` command line. It is enabled if the binary can be found in the current `$PATH`. Its code is the following: ```{.liquidsoap include="decoder-flac.liq"} ``` Additionally, a metadata resolver is registered when the `metaflac` command can be found in the `$PATH`: ```{.liquidsoap include="decoder-metaflac.liq"} ``` ### The faad decoder The faad decoder uses the `faad` program, if found in the `$PATH`. It can decode AAC and AAC+ audio files. This program does not support reading encoded data from its standard input so the decoder is registered using `decoder.oblivious.add`. Its code is the following: ```{.liquidsoap include="decoder-faad.liq"} ``` ���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/external_encoders.md���������������������������������������������������0000664�0000000�0000000�00000006547�14773033502�0022155�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������## Introduction You can use any external program that accepts wav or raw PCM data to encode audio data and use the resulting compressed stream as an output, either to a file, a pipe, or even icecast. When using an external encoding process, uncompressed PCM data will be sent to the process through its standard input (`stdin`), and encoded data will be read through its standard output (`stdout`). When using a process that does only file input or output, `/dev/stdin` and `/dev/stdout` can be used, though this may generate issues if the encoding process expects to be able to go backward/forward in the file. ## External encoders The main operators that can be used with external encoders are: - `output.file` - `output.icecast` In order to use external encoders with these operators, you have to use the `%external` [encoding format](encoding_formats.html). Its syntax is: ```liquidsoap %external(channels=2,samplerate=44100,header=true, restart_on_crash=false, restart_on_metadata, restart_after_delay=30, process="progname") ``` The available options are: - `process`: this parameter is a function that takes the current metadata and return the process to start. - `header`: if set to `false` then no WAV header will be added to the data fed to the encoding process, thus the encoding process shall operate on RAW data. - `restart_on_crash`: whether to restart the encoding process if it crashed. Useful when the external process fails to encode properly data after some time. - `restart_on_metadata`: restart encoding process on each new metadata. Useful in conjunction with the `process` parameter for audio formats that need a new header, possibly with metadatas, for each new track. This is the case for the ogg container. - `restart_encoder_delay`: Restart the encoder after some delay. This can be useful for encoders that cannot operate on infinite streams, or are buggy after some time, like the `lame` binary. The default for `lame` and `accplusenc`-based encoders is to restart the encoder every hour. Only one of `restart_encoder_delay` or `restart_on_new_track` should be used. The restart mechanism strongly relies on the good behaviour of the encoding process. The restart operation will close the standard input of the encoding process. The encoding process is then expected to finish its own operations and close its standard output. If it does not close its standard output, the encoding task will not finish. If your encoding process has this issue, you should turn the `restart_on_crash` option to `true` and kill the encoding process yourself. If you use an external encoder with the `output.icecast` operator, you should also use the following options of `output.icecast`: - `icy_metadata`: send new metadata as ICY update. This is the case for headerless formats, such as MP3 or AAC, and it appears to work also for ogg/vorbis streams. - `format`: Content-type (mime) of the data sent to icecast. For instance, for ogg data, it is one of `"application/ogg"`, `"audio/ogg"` or `"video/ogg"` and for mp3 data it is `"audio/mpeg"`. ## Video support Videos can also be encoded by programs able to read files in avi format from standard input. To use it, the flag `video=true` of `%external` should be used. For instance, a compressed avi file can be generated with `ffmpeg` using ```{.liquidsoap include="external-output.file.liq" from="BEGIN"} ``` ���������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/external_streams.md����������������������������������������������������0000664�0000000�0000000�00000002460�14773033502�0022017�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������## Introduction You can use an external program to create a source that will read data coming out of the standard output (`stdout`) of this program. Contrary to the external file decoders, data will be buffered and played when a sufficient amount was accumulated. The program should output data in signed 16 bits little endian PCM (s16le). Number of channels and samplerate can be specified. There is no need of any wav header in the data, though it should work too. ## Basic operator The basic operators for creating an external stream are `input.external.wav`, `input.external.rawaudio`, `input.external.avi` and `input.external.rawvideo` (depending on the format of the data produced by the external program). The parameters for the two first are - `buffer`: Duration of the pre-buffered data. - `max`: Maximum duration of the buffered data. - `channels`: Number of channels. - `samplerate`: Sample rate. - `restart`: Restart the process when it has exited normally. - `restart_on_error`: Restart the process when it has exited with error. The last parameter is unlabeled. It is a string containing the command that will be executed to run the external program. ## Wrappers A wrapper, `input.mplayer`, is defined to use mplayer as the external decoder. Its code is: ```{.liquidsoap include="input.mplayer.liq"} ``` ����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/faq.md�����������������������������������������������������������������0000664�0000000�0000000�00000020755�14773033502�0017215�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Frequently Asked Questions ## What does this message means? ### Type error Liquidsoap might also reject a script with a series of errors of the form ` this value has type ... but it should be a subtype of ...` . Usually the last error tells you what the problem is, but the previous errors might provide a better information as to where the error comes from. For example, the error might indicate that a value of type `int` has been passed where a float was expected, in which case you should use a conversion, or more likely change an integer value such as `13` into a float `13.`. A type error can also show that you're trying to use a source of a certain content type (e.g., audio) in a place where another content type (e.g., pure video) is required. In that case the last error in the list is not the most useful one, but you will read something like this above: ``` At ...: Error 5: this value has type source(video=canvas(_),...) but it should be a subtype of source(audio=pcm(_),...) ``` Sometimes, the type error actually indicates a mistake in the order or labels of arguments. For example, given `output.icecast(mount="foo.ogg",source)` liquidsoap will complain that the second argument is a source (`source(?A)`) but should be a format (`format(?A)`): indeed, the first unlabelled argument is expected to be the encoding format, e.g., `%vorbis`, and the source comes only second. Finally, a type error can indicate that you have forgotten to pass a mandatory parameter to some function. For example, on the code `fallback([source.mux.audio(x),...])`, liquidsoap will complain as follows: ``` At line ...: Error 5: this value has type [(?id : _, audio : _) -> _] but it should be a subtype of the type of the value at ../libs/switches.liq, line 11, char 11-18 [source(_)] (inferred at ../libs/list.liq, line 102, char 29) ``` Indeed, `fallback` expects a source, but `source.mux.audio(x)` is still a function expecting the `audio` parameter. ### That source is fallible! See the [quickstart](quick_start.html), or read more about [sources](sources.html). ### Clock error Read about [clocks](clocks.html) for the errors `a source cannot belong to two clocks` and `cannot unify two nested clocks`. ### We must catchup x.xx! This error means that a clock is getting late in liquidsoap. This can be caused by an overloaded CPU, if your script is doing too much encoding or processing: in that case, you should reduce the load on your machine or simplify your liquidsoap script. The latency may also be caused by some lag, for example a network lag will cause the icecast output to hang, making the clock late. The first kind of latency is problematic because it tends to accumulate, eventually leading to the restarting of outputs: ``` Too much latency! Resetting active source... ``` The second kind of latency can often be ignored: if you are streaming to an icecast server, there are several buffers between you and your listeners which make this problem invisible to them. But in more realtime applications, even small lags will result in glitches. In some situations, it is possible to isolate some parts of a script from the latency caused by other parts. For example, it is possible to produce a clean script and back it up into a file, independently of its output to icecast (which again is sensitive to network lags). For more details on those techniques, read about [clocks](clocks.html). ### Unable to decode ``file'' as {audio=pcm}! This log message informs you that liquidsoap failed to decode a file, not necessarily because it cannot handle the file, but also possibly because the file does not contain the expected media type. For example, if audio and video is expected, an audio file with no video will be rejected. Liquidsoap is also able to convert audio channels in most situations. Typically, if stereo data is expected but the file contains mono audio, liquidsoap will use the single audio channel as both left and right channels. ### Runtime exceptions Liquidsoap scripts can raise runtime errors of the form: ``` At line 3, char 45: Error 14: Uncaught runtime error: type: not_found, message: "File not found!" ``` These are errors that the script programmer can catch and decide what to do when they occur. Such errors will typically occur when trying to read a file that does not exist and etc. The [language page](language.html) has more details about errors, how to raise them and how to catch them. You can head over there to get more information. ### Crashes Liquidsoap dies with messages such as these by the end of the log: ``` ... [threads:1] Thread "XXX" aborts with exception YYY! ... [stderr:3] Thread 2 killed on uncaught exception YYY. ... [stderr:3] Raised at file ..., line ..., etc. ``` Those internal errors can be of two sorts: - **Bug**: Normally, this means that you've found a bug, which you should report on the mailing list or bug tracker. - **User error**: In some cases, we let an exception go on user errors, instead of nicely reporting and handling it. By looking at the surrounding log messages, you might realize that liquidsoap crashed for a good reason, that you are responsible for fixing. You can still report a bug: you should not have seen an exception and its backtrace. In any case, once that kind of error happens, there is no way for the user to prevent liquidsoap from crashing. Those exceptions cannot be caught or handled in any way at the level of liquidsoap scripts. ## Troubleshooting ### Pulseaudio When using ALSA input or output or, more generally any audio input or output that is not using pulseaudio, you should disable pulseaudio, which is often installed by default. Pulseaudio emulates ALSA but this also generates bugs, in particular errors of this form: ``` Alsa.Unknown_error(1073697252)! ``` There are two things you may do: - Make sure your alsa input/output does not use pulseaudio - Disable pulseaudio on your system In the first case, you should first find out which sound card you want to use, with the command `aplay -l`. An example of its output is: ``` **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 ``` In this case, the card we want to use is: device `0`, subdevice `0`, thus: `hw:0,0`. We now create a file `/etc/asound.conf` (or `~/.asoundrc` for single-user configuration) that contains the following: ```liquidsoap pcm.liquidsoap { type plug slave { pcm "hw:0,0" } } ``` This creates a new alsa device that you can use with liquidsoap. The `plug` operator in ALSA is used to work-around any hardware limitations in your device (mixing multiple outputs, resampling etc.). In some cases you may need to read more about ALSA and define your own PCM device. Once you have created this device, you can use it in liquidsoap as follows: ```liquidsoap input.alsa(device="pcm.liquidsoap", ...) ``` In the second case -- disabling pulseaudio, you can edit the file `/etc/pulse/client.conf` and change or add this line: ``` autospawn = no ``` And kill any running pulseaudio process: ``` killall pulseaudio ``` Otherwise you may simply remove pulseaudio's packages, if you use Debian or Ubuntu: ``` apt-get remove pulseaudio libasound2-plugins ``` ### Listeners are disconnected at the end of every track Several media players, including renowned ones, do not properly support Ogg/Vorbis streams: they treat the end of a track as an end of file, resulting in the disconnection. Players that are affected by this problem include VLC. Players that are not affected include ogg123, liquidsoap. One way to work around this problem is to not use Ogg/Vorbis (which we do not recommend) or to not produce tracks within a Vorbis stream. This is done by dropping both metadata and track marks (for example using `source.drop.metadata_track_marks`). ### Encoding blank Encoding pure silence is often too effective for streaming: data is so compressed that there is nothing to send to listeners, whose clients eventually disconnect. Therefore, it is a good idea to use a non-silent jingle instead of `blank()` to fill in the blank. You can also achieve various effects using synthesis sources such as `noise()`, `sine()`, etc. ### Temporary files Liquidsoap relies on OCaml's `Filename.tmp_dir_name` variable to store temporary files. It is documented as follows: The name of the temporary directory: Under Unix, the value of the `TMPDIR` environment variable, or `"/tmp"` if the variable is not set. Under Windows, the value of the `TEMP` environment variable, or `"."` if the variable is not set. �������������������liquidsoap-2.3.2/doc/content/ffmpeg.md��������������������������������������������������������������0000664�0000000�0000000�00000026210�14773033502�0017702�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# FFmpeg Support Since the `2.0.x` release cycle, liquidsoap integrates a tight support of ffmpeg. This includes: - [Decoders](#decoders) - [Encoders](#encoders) - [Filters](#filters) - [Bitstream filters](#bitstream-filters) - [Encoded data tweaks](#encoded-data-tweaks) - [Examples](#examples) Ffmpeg support includes 3 types of content: - **Internal content**, that is content available to all liquidsoap operators: `PCM` audio and `YUV420p` video - **Raw content**, that is decoded content but stored as ffmpeg internal frame. This type of content is only available to ffmpeg filters and raw encoders. It can be used to avoid data copies back and forth between liquidsoap and ffmpeg. - **Copy content**, that is encoded content stored as ffmpeg internal packets. This type of content is only available to ffmpeg copy encoder and bitstream filters and requires a fairly good understanding of media codecs and containers. Copy contents can be used to avoid transcoding and pass encoded data end-to-end inside liquidsoap scripts. ## Enabling ffmpeg support FFmpeg support is available via the external [ocaml-ffmpeg](https://github.com/savonet/ocaml-ffmpeg) binding package. If you are using any binary asset from our release pages or via docker, this should already be included. If you are installing via [opam](https://opam.ocaml.org/), installing the `ffmpeg` package should do the trick: ```sh % opam install ffmpeg ``` ### fdk-aac support in ffmpeg One common question is how to install `ffmpeg` with `fdk-aac` support. This can get tricky because you need the _ffmpeg shared libraries_ compiled with `libfdk-aac`. This means that installing `libfdk-aac` alone will not be enough, you might also need to recompile `ffmpeg` to take advantage of it. When recompiling `ffmpeg`, make sure that the `--enable-shared` argument is passed to the `configure` script. Also, compiling the shared libraries is different than downloading the `ffmpeg` command line. Most `ffmpeg` downloads include a _static build_ of ffmpeg that is, one that does not use or provide shared libraries. On linux platforms, you can check what dynamic libraries liquidsoap is using using ```shell ldd /path/to/liquidsopap ``` On macos, you can use `otool -L`. In the list of libraries, you should see `libavcodec`. In turn, you should be able to use the same command to inspect the libraries required by the `libavcodec` used by the `liquidsoap` binary. If this includes `libfdk-aac`, you're good to go! On debian, you might be able to use [deb-multimedia.org](https://www.deb-multimedia.org/) to install a build of `ffmpeg` with `libfdk-aac` enabled. You are advised to follow the instructions on the website for the latest up-to date guide. You may also refer to [this conversation](https://github.com/savonet/liquidsoap/discussions/3027#discussioncomment-6072338). ## Decoders For the most part, you should never have to worry about the `ffmpeg` decoder. When enabled, it should be the preferred decoder for all supported media. When using raw or copied content, the decoder is able to produce the required content without the need of any intervention on the user part. Should you need to tweak it, here are a couple of pointers: The `settings.decoder.decoders` settings controls which decoders are to be used when trying to decode media files. You can use it to restrict which decoders are being used, for instance making sure only the ffmpeg decoder is used: ```liquidsoap settings.decoder.decoders := ["FFMPEG"] ``` Priority for the decoder is set via: ```liquidsoap settings.decoder.priorities.ffmpeg := 10 ``` You can use this setting to adjust whether or not the ffmpeg decoder should be tried first when decoding media files, in particular in conjunction with the other `settings.decoder.priorities.*` settings. For each type of media codec, the `settings.decoder.ffmpeg.codecs.*` settings can be used to tell `ffmpeg` which decoder to use to decode this type of content (there could more than one decoder for a given codec). For instance, for the `aac` codec: - `settings.decoder.ffmpeg.codecs.aac.available()` returns the list of available decoders, typically `["aac", "aac_fixed"]`. - `settings.decoder.ffmpeg.codecs.aac` can be used to choose which decoder should be used, typically: `settings.decoder.ffmpeg.codecs.aac := "aac"` When debugging issues with `ffmpeg`, it can be useful to increase the log verbosity. ```liquidsoap settings.ffmpeg.log.verbosity := "warning" ``` This settings sets the verbosity of `ffmpeg` logs. Possible values, from less verbose to more verbose are: `"quiet"`, `"panic"`, `"fatal"`, `"error"`, `"warning"`, `"info"`, `"verbose"` or `"debug"` Please note that, due to a technical limitation, we are not yet able to route `ffmpeg` logs through the liquidsoap logging facilities, which means that `ffmpeg` logs are currently only printed to the process's standard output and that the `settings.ffmpeg.log.level` is currently not used. ### Decoder arguments In some cases, for instance when sending raw PCM data, it might be required to pass some arguments to the ffmpeg decoder to let it know what kind of format, codec, etc. it should decode. There are two ways to do that: - For _streams_, the `content_type` argument can be used. The convention is to use `"application/ffmpeg;<arguments>"`. - For _files_, the `ffmpeg_options` metadata can be used, for instance using the `annotate` protocol: `annotate:ffmpeg_options="<arguments>":/path/to/file.raw` Here's an example of a SRT input and output that can be used to send raw PCM data between two instances: Sender: ```liquidsoap enc = %ffmpeg( format="s16le", %audio( codec="pcm_s16le", ac=2, ar=48000 ) ) output.srt(enc, s) ``` Receiver: ```liquidsoap s = input.srt( content_type="application/ffmpeg;format=s16le,ch_layout=stereo,sample_rate=48000" ) ``` If, instead of using `output.srt` above, we were using `output.file` and saving to a file named `bla.raw`, this file could be read with a `single` source this way: ```liquidsoap s = single("annotate:ffmpeg_options='format=s16le,ch_layout=stereo,sample_rate=44100':/tmp/bla.raw") ``` This could also be done in a `playlist` or `request.dynamic` and etc. ## Encoders See detailed [ffmpeg encoders](ffmpeg_encoder.html) article. ## Filters See detailed [ffmpeg filters](ffmpeg_filters.html) article. ## Bitstream filters FFmpeg bitstream filters are filters that modify the binary content of _encoded data_. They can be used to adjust certain aspects of media codecs and containers to make them fit some specific use, for instance a rtmp/flv output etc. They are particularly important when dealing with live switches of encoded content (see [Examples](#examples) section). The list of all bitstream filters is documented on [FFmpeg](https://www.ffmpeg.org/ffmpeg-bitstream-filters.html) online doc and our [extra API reference](reference-extras.html). Here's one such filter: ```liquidsoap % liquidsoap -h ffmpeg.filter.bitstream.h264_mp4toannexb FFmpeg h264_mp4toannexb bitstream filter. See ffmpeg documentation for more details. Type: (?id : string?, source(video=ffmpeg.copy('a), 'b)) -> source(video=ffmpeg.copy('a), 'b) Category: Source / FFmpeg filter Arguments: * id : string? Force the value of the source ID. * (unlabeled) : source(video=ffmpeg.copy('a), 'b) Methods: ... ``` Please consult the FFmpeg documentation for more details about that each filter do and why/how to use them. ## Encoded data tweaks Manipulating encoded content is powerful but can sometimes require some specific knowledge of internals aspects of media codecs and containers. This section lists some specific cases. ### Relaxed copy content compatibility check By default, liquidsoap keeps track of the content passed in a stream containing ffmpeg encoded content (`ffmpeg.copy`) and only allows file and stream decoders to return strictly compatible content, e.g. same video resolution or audio samplerate. Some containers such as `mp4`, however, do allow stream where video resolution or audio samplerate changes between tracks. In this case, you can relax those compatibility checks using the following setting: ```liquidsoap settings.ffmpeg.content.copy.relaxed_compatibility_check := true ``` This is a global setting for now and could be refined per-stream in the future if the needs arises. ### Shared encoders `liquisoap` provides operators to encode data using `%ffmpeg` and reuse it across output. This is called _inline encoding_. Here's an example: ```liquidsoap audio_source = single(audio_url) video_source = single(image) stream = source.mux.video(video=video_source, audio_source) stream = ffmpeg.encode.audio_video( %ffmpeg( %audio(codec="aac", b="128k"), %video(codec="libx264", b="4000k") ), stream ) flv = %ffmpeg( format="flv", %audio.copy, %video.copy, ) # Send to one youtube output: output.youtube.live.rtmp( encoder = flv, stream, ... ) mpegts = %ffmpeg( format="mpegts", %audio.copy, %video.copy, ) # And to a hls one: output.file.hls( ["mpegts", mpegts], stream, ... ) ``` Working with encoded data, however, requires a bit of knowledge of ffmpeg internal and media codecs and containers. Here, for instance, this stream will have issues because the `flv` format requires global data, something that in ffmpeg terms is called `extradata`. When working with a single encoder such as: ```liquidsoap %ffmpeg( format="flv", %audio(codec="aac", b="128k"), %video(codec="libx264", b="4000k") ) ``` We are aware when initializing the encoders that it is aimed for a `flv` container so the code implicitly enables the global header for each encoder. However, when encoding inline, we do not know at the time of encoding the container that will be used to encapsulate the stream, even worst, it can be used potentially with different containers with different requirements! In our case here, you have two ways to solve the issue: If you know that all the containers will be okay with global header, you can enable the corresponding flag in the encoder: ```liquidsoap stream = ffmpeg.encode.audio_video( %ffmpeg( %audio(codec="aac", b="128k", flags="+global_header"), %video(codec="libx264", b="4000k", flags="+global_header") ), stream ) ``` However, it is also possible that one stream needs global header but not the other one, which is the case here with `mpegts`. In this case, you can use the _bitstream filter_ `ffmpeg.filter.bitstream.extract_extradata` to extract global data to only one stream: ``` audio_source = single(audio_url) video_source = single(image) stream = source.mux.video(video=video_source, audio_source) stream = ffmpeg.encode.audio_video( %ffmpeg( %audio(codec="aac", b="128k"), %video(codec="libx264", b="4000k") ), stream ) flv = %ffmpeg( format="flv", %audio.copy, %video.copy, ) flv_stream = ffmpeg.filter.bitstream.extract_extradata(stream) # Send to one youtube output: output.youtube.live.rtmp( encoder = flv, flv_stream, ... ) mpegts = %ffmpeg( format="mpegts", %audio.copy, %video.copy, ) # And to a hls one: output.file.hls( ["mpegts", mpegts], stream, ... ) ``` ## Examples See detailed [ffmpeg cookbook](ffmpeg_cookbook.html) article. ����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/ffmpeg_cookbook.md�����������������������������������������������������0000664�0000000�0000000�00000006551�14773033502�0021576�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# FFmpeg cookbook Here are some examples of what is possible to do with the ffmpeg support in liquidsoap: ## Relaying without re-encoding With ffmpeg support, Liquidsoap can relay encoded streams without re-encoding them, making it possible to re-send a stream to multiple destinations. Here's an example: ```{.liquidsoap include="ffmpeg-relay.liq"} ``` We cannot use `mksafe` here because the content is not plain `pcm` samples, which this operator is designed to produce. There are several ways to make the source infallible, however, either by providing a `single(...)` source with the same encoded content as we expect from `encoded_source` or by creating an infallible source using `ffmpeg.encode.audio`. ## On-demand relaying without re-encoding Another refinement on the previous example is the capacity to relay a stream only when listeners are connected to it, all without re-encoding the content. To make it work, you will need a format that can be handled by `ffmpeg` for that purpose. `mp3` is a good example. In the script below, you need to match the encoded format of the stream with a blank file (or any other file). The `output.harbor` will then relay the data from the file if no one is connected and start/stop the underlying input when there are listeners: ```{.liquidsoap include="ffmpeg-relay-ondemand.liq"} ``` ## Shared encoding Liquidsoap can also encode in one place and share the encoded with data with multiple outputs, making it possible to minimize CPU resources. Here's an example adapted from the previous one: ```{.liquidsoap include="ffmpeg-shared-encoding.liq"} ``` Shared encoding is even more useful when dealing with video encoding, which is very costly. Here's a fun example sharing audio and video encoding and sending to different destinations, both via Icecast and to YouTube/Facebook via the rtmp protocol: ```{.liquidsoap include="ffmpeg-shared-encoding-rtmp.liq"} ``` ## Add transparent logo and video See: https://github.com/savonet/liquidsoap/discussions/1862 ## Live switch between encoded content _This is an ongoing development effort. Please refer to the online support channels if you are experiencing issues with this kind of feature._ Starting with liquidsoap `2.1.x`, it is gradually becoming possible to do proper live switches on encoded content and send the result to different outputs. Please note that this requires a solid knowledge of media codecs, containers and ffmpeg bitstream filters. Different input and output containers store codec binary data in different ways and those are not always compatible. This requires the use of bitstream filters to adapt the binary data and, it's possible some new filters will need to be written to support more combinations of input/output and codecs. Here's a use case that has been tested: live switch between a playlist of mp4 files and a rtmp flv input: ```{.liquidsoap include="live-switch.liq"} ``` - We need the `h264_mp4toannexb` on each stream to make sure that the mp4 data conforms to what the mpegts container expect - We need to disable ffmpeg's automatic insertion of bitstream filters via `-autobsf`. FFmpeg does not support this kind of live switch at the moment and its automatically inserted filters won't work, which is why we're doing it ourselves. That's it! In the future we want to extend this use-case to also be able to output to a `rtmp` output from the same data. And more! �������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/ffmpeg_encoder.md������������������������������������������������������0000664�0000000�0000000�00000020620�14773033502�0021400�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# FFmpeg encoder The `%ffmpeg` encoder should support all the options for `ffmpeg`'s [muxers](https://ffmpeg.org/ffmpeg-formats.html#Muxers) and [encoders](https://www.ffmpeg.org/ffmpeg-codecs.html), including private configuration options. Configuration value are passed as key/values, with values being of types: `string`, `int`, or `float`. If an option is not recognized (or: unused), it will raise an error during the instantiation of the encoder. Here are some configuration examples: ### Interleaved muxing FFmpeg provides two different APIs for muxing data, interleaved or not. The interleaved API buffers packets waiting to be outputted to make sure that all streams, e.g. audio and video, have their packets as close to each other as possible. This ensures that for instance, the stream does not start with a long chunk of audio data without any video content. However, this can come with some increased memory usage due to buffering. On the other hand, the non-interleaved API allows to send encoded packets directly to the output without intermediate buffering. This can sometimes result in better latency and lower memory usage. The `%ffmpeg` encoder can use either API. By default, it uses the interleaved API when encoding more than one stream. You can also specify the interleaving mode by passing the `interleaved` parameter: `%ffmpeg(interleaved=<true|false|"default">, ...)`. You might also want to take this into consideration when setting your encoder's parameters. Some video encoders can buffer frames for a while before outputting the first encoded frame, which can also create issues even with the interleaved API enabled (the interleaving buffer has a max size too!). Typically, with `libx264`, you can set `tune = "zerolatency"` to make sure that the encoder starts outputting data right away. ### Encoding examples - **AAC encoding at `22050kHz` using `fdk-aac` encoder and `mpegts` muxer** ```liquidsoap %ffmpeg(format="mpegts", %audio( codec="libfdk_aac", samplerate=22050, b="32k", afterburner=1, profile="aac_he_v2" ) ) ``` - **Mp3 encoding using `libshine` at `48000kHz`** ```liquidsoap %ffmpeg(format="mp3", %audio(codec="libshine", samplerate=48000)) ``` - **AC3 audio and H264 video encapsulated in an MPEG-TS stream** ```liquidsoap %ffmpeg( format="mpegts", %audio(codec="ac3", channel_coupling=0), %video( codec="libx264", b="2600k", "x264-params"="scenecut=0:open_gop=0:min-keyint=150:keyint=150", preset="ultrafast" ) ) ``` - **AC3 audio and H264 video encapsulated in an MPEG-TS stream using ffmpeg raw frames** ```liquidsoap %ffmpeg( format="mpegts", %audio.raw(codec="ac3", channel_coupling=0), %video.raw( codec="libx264", b="2600k", "x264-params"="scenecut=0:open_gop=0:min-keyint=150:keyint=150", preset="ultrafast" ) ) ``` - **Mp3 encoding using `libmp3lame` and video copy** ```liquidsoap %ffmpeg( format="mp3", %audio(codec="libmp3lame"), %video.copy ) ``` The full syntax is as follows: ```liquidsoap %ffmpeg( format=<format>, # Audio section %audio(codec=<codec>, <option_name>=<option_value>, ...), # Or: %audio.raw(codec=<codec>, <option_name>=<option_value>, ...), # Or: %audio.copy(<option>), # Video section %video(codec=<codec>, <option_name>=<option_value>, ...), # Or: %video.raw(codec=<codec>, <option_name>=<option_value>, ...), # Or: %video.copy(<option>), # Generic options <option_name>=<option_value>, ... ) ``` Where: - `<format>` is either a string value (e.g. `"mpegts"`), as returned by the `ffmpeg -formats` command or `none`. When set to `none` or simply no specified, the encoder will try to auto-detect it. - `<codec>` is a string value (e.g. `"libmp3lame"`), as returned by the `ffmpeg -codecs` command. - `<option_name>` can be any syntactically valid variable name or string. Strings are typically used when the option name is of the form: `foo-bar`. - `%audio(...)` is for options specific to the audio codec. Unused options will raise an exception. Any option supported by `ffmpeg` can be passed here. Streams encoded using `%audio` are using liquidsoap internal frame format and are fully handled on the liquidsoap side. - `%audio.raw(...)` behaves like `%audio` except that the audio data is kept as ffmpeg's internal format. This can avoid data copy and is also the format required to use [ffmpeg filters](ffmpeg_filters.html). - `%audio.copy` copies data without decoding or encoding it. This is great to avoid using the CPU, but in this case, the data cannot be processed with operators that modify it, such as `fade.{in,out}` or `smart_cross`. Also, all streams must agree on the same data format. - `%video(...)` is for options specific to the video codec. Unused options will raise an exception. Any option supported by `ffmpeg` can be passed here. - `%video.raw` and `%video.copy` have the same meaning as their `%audio` counterpart. - Generic options are passed to audio, video and format (container) setup. Unused options will raise an exception. Any option supported by `ffmpeg` can be passed here. ### HLS output The `%ffmpeg` encoder is the prime encoder for HLS output as it is the only one of our collection of encoder which can produce Mpeg-ts muxed data, which is required by most HLS clients. ### File output Some encoding formats, for instance `mp4`, require to rewind their stream and write a header after the fact, when encoding of the current track has finished. For historical reasons, such formats cannot be used with `output.file`. To remedy that, we have introduced the `output.url` operator. When using this operator, the encoder is fully in charge of the output file and can thus write headers after the fact. The `%ffmpeg` encoder is one such encoder that can be used with this operator. ### Copy options The `%audio.copy` and `%video.copy` encoders have two mutually exclusive options to handle keyframes: - `%audio.copy(wait_for_keyframe)` and `%video.copy(wait_for_keyframe)`: Wait until at least one keyframe has been passed to start passing encoded packets from a new stream. - `%audio.copy(ignore_keyframe)` and `%video.copy(ignore_keyframe)`: Ignore all keyframes. These options are useful when switching from one encoded stream to the next. With option `wait_for_keyframe`, the encoder discards any new packet at the beginning of a stream until a keyframe is passed. This means that playback will be paused until it can be resumed properly with no decoding glitches. This option is implemented globally when possible, i.e. in case of a video track with keyframes and an audio track with no keyframes, the audio track will discard packets until a video keyframe has been passed. This is the default option. With option `ignore_keyframe`, the encoder starts passing encoded data right away. Content is immediately added but playback might get stuck until a new keyframe is passed. It is worth noting that some audio encoders may also have keyframes. ### Hardware acceleration The `%ffmpeg` encoder supports multiple hardware acceleration provided by `ffmpeg`. If you are lucky and the encoder you are using provides support for hardware acceleration without any specific configuration, all you might have to do is select `codec="..."` (for instance on macOS, `codec="h264_videotoolbox"`) and it should work immediately. The type of hardware acceleration provided by ffmpeg are: 1. Internal hardware acceleration that works without any specific configuration. This is the happy path described above! 2. Device-based hardware acceleration that works with a specific device. 3. Frame-based hardware acceleration that work with a specific pixel format. The type of hardware acceleration to use for a given stream can be specified using the `hwaccel` option. Its value is one of: `"auto"`, `"none"`, `"internal"`, `"device"` or `"frame"`. For device-based hardware acceleration, the device to use can be specified using `hwaccel_device`. For frame-based hardware acceleration, the pixel format can be specified using `hwaccel_pixel_format`. In most cases, liquidsoap should be able to guess these values from the codec. Here's an example: ```liquidsoap enc = %ffmpeg( format="mpegts", %video( hwaccel="device", hwaccel_devic="/dev/...", ... ) ) ``` Hardware acceleration support is, of course, very hardware dependent, so we might not have tested all possible combinations. If you are having issues setting it up, do not hesitate to get in touch with us to see if your use-case is properly covered. ����������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/ffmpeg_filters.md������������������������������������������������������0000664�0000000�0000000�00000013020�14773033502�0021425�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# FFmpeg filters [FFmpeg filters](https://ffmpeg.org/ffmpeg-filters.html) provide audio and video filters that can be used to transform content using the ffmpeg library. They are enabled in liquidsoap when compiled with the optional [ffmpeg-avfilter](https://github.com/savonet/ocaml-ffmpeg). ## Filter as operators If enabled, the filters should appear as operators, prefixed with `ffmpeg.filter`. For instance: ``` Ffmpeg filter: Add echoing to the audio. Type: (?in_gain : float?, ?out_gain : float?, ?delays : string?, ?decays : string?, ffmpeg.filter.graph, ffmpeg.filter.audio) -> ffmpeg.filter.audio Category: Liquidsoap Parameters: * in_gain : float? (default: null) set signal input gain. (default: 0.6) * out_gain : float? (default: null) set signal output gain. (default: 0.3) * delays : string? (default: null) set list of signal delays. (default: "1000") * decays : string? (default: null) set list of signal decays. (default: "0.5") * (unlabeled) : ffmpeg.filter.graph (default: None) * (unlabeled) : ffmpeg.filter.audio (default: None) ``` Filters input and output are abstract values of type `ffmpeg.filter.audio` and `ffmpeg.filter.video`. They can be created using `ffmpeg.filter.audio.input`, `ffmpeg.filter.video.input`. These operators take [media tracks](multitrack.html) as input. Conversely, tracks can be created from them using `ffmpeg.filter.audio.output` and `ffmpeg.filter.video.output`. Filters are configured within the closure of a function. Here's an example: ```{.liquidsoap include="ffmpeg-filter-flanger-highpass.liq"} ``` This filter receives an audio input, creates a `ffmpeg.filter.audio.input` with it that can be passed to filters, applies a flanger effect and then a high pass effect, creates an audio output from it and returns it. Here's another example for video: ```{.liquidsoap include="ffmpeg-filter-hflip.liq"} ``` This filter receives a video input, creates a `ffmpeg.filter.video.input` with it that can be passed to filters, applies a `hflip` filter (flips the video vertically), creates a video output from it and returns it. ## Applying filters to a source When applying a filter, the input is placed in a clock that is driven by the output. This means that you cannot share other tracks from the input to the output. This can be an annoying source of confusion. Thus, when applying FFMpeg filters to sources with audio and video tracks, it is recommended to pass all the tracks through the filter, even if they are simply copied. Here's an example with the previous filter: ```{.liquidsoap include="ffmpeg-filter-hflip2.liq"} ``` FFmpeg filters are very powerful, they can also convert audio to video, for instance displaying information about the stream, and they can combined into powerful graph processing filters. ## Filter commands Some filters support [changing options at runtime](https://ffmpeg.org/ffmpeg-filters.html#Changing-options-at-runtime-with-a-command) with a command. These are also supported in liquidsoap. In order to do so, you have to use a slightly different API: ```{.liquidsoap include="ffmpeg-filter-dynamic-volume.liq" to="END"} ``` First, we instantiate a volume filter via `ffmpeg.filter.volume.create`. The filter instance has a `process_command`, which we use to create the `set_volume` function. Then, we apply the expected input to the filter and return the pair `(s, set_volume)` of source and function. The `ffmpeg.filter.<filter>.create` API is intended for advanced use if you want to use filter commands. Otherwise, `ffmpeg.filter.<filter>` provides a more straight forward API to filters. ## Filters with dynamic inputs or outputs Filters with dynamic inputs or outputs can have multiple inputs or outputs, decided at run-time. Typically, `ffmpeg.filter.split` splits a video stream into multiple streams and `ffmpeg.filter.merge` merges multiple video streams into a single one. For these filters, the operators' signature is a little different. Here's an example for dynamic outputs: ``` % liquidsoap -h ffmpeg.filter.asplit Ffmpeg filter: Pass on the audio input to N audio outputs. This filter has dynamic outputs: returned value is a tuple of audio and video outputs. Total number of outputs is determined at runtime. Type: (?outputs : int?, ffmpeg.filter.graph, ffmpeg.filter.audio) -> [ffmpeg.filter.audio] * [ffmpeg.filter.video] Category: Liquidsoap Flag: extra Parameters: * outputs : int? (default: null) set number of outputs. (default: 2) * (unlabeled) : ffmpeg.filter.graph (default: None) * (unlabeled) : ffmpeg.filter.audio (default: None) ``` This filter returns a tuple `(audio, video)` of possible dynamic outputs. Likewise, with dynamic inputs: ``` % liquidsoap -h ffmpeg.filter.amerge Ffmpeg filter: Merge two or more audio streams into a single multi-channel stream. This filter has dynamic inputs: last two arguments are lists of audio and video inputs. Total number of inputs is determined at runtime. Type: (?inputs : int?, ffmpeg.filter.graph, [ffmpeg.filter.audio], [ffmpeg.filter.video]) -> ffmpeg.filter.audio Category: Liquidsoap Flag: extra Parameters: * inputs : int? (default: null) specify the number of inputs. (default: 2) * (unlabeled) : ffmpeg.filter.graph (default: None) * (unlabeled) : [ffmpeg.filter.audio] (default: None) * (unlabeled) : [ffmpeg.filter.video] (default: None) ``` This filter receives an array of possible `audio` inputs as well as an array of possible `video` inputs. Put together, this can be used as such: ```{.liquidsoap include="ffmpeg-filter-parallel-flanger-highpass.liq"} ``` ����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/flows_devel.md���������������������������������������������������������0000664�0000000�0000000�00000002554�14773033502�0020754�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Developing Flows [Flows](flows.html) is handled on the [Heroku](https://www.heroku.com/) platform. ## Getting started First steps to get started. - Create an account on [Heroku](https://www.heroku.com/). - Install the [Heroku utilities](https://toolbelt.heroku.com/). - Ask a Liquidsoap administrator to give you access to the repositories. The repositories of the main components are organized as follows. - `savonet-flows` is the python handler to submit metadata: - the associated [github repository](https://github.com/savonet/flows-submit) - the Heroku repository is `git@heroku.com:savonet-liquidsoap.git` - `savonet-flows-socket` is the node application to serve the webpage and client stuff. - the associated [github repository](https://github.com/savonet/flows-push) - the [test Heroku webpage](http://savonet-flows-socket.herokuapp.com/) is updated by pushing on `git@heroku.com:savonet-flows-socket-next.git` - the [prod Heroku webpage](http://savonet-flows-socket.herokuapp.com/) is updated by pushing on `git@heroku.com:savonet-flows-socket.git` Some more experimental repositories include: - a [command-line client](https://github.com/savonet/flows-client) ## Useful commands Getting the environment variables: ``` heroku config -s --app savonet-flows ``` Seeing the logs of the socket application: ``` heroku logs -t --app savonet-flows-socket ``` ����������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/frequence3.md����������������������������������������������������������0000664�0000000�0000000�00000000752�14773033502�0020501�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Fréquence 3 [Fréquence 3](http://www.frequence3.fr) uses Liquidsoap mainly on the backstage, for different purposes: - transcoding for different formats (OGG, weird MP3 relays...) - scheduling and playlist for audio backup streams, and test streams - blank detection They look forward to using Liquidsoap even more, and work with the Savonet team to make sure this tool can ease the work of webradios :) They provide an MP3 stream [here](http://streams.frequence3.net/mp3-128.m3u). ����������������������liquidsoap-2.3.2/doc/content/geekradio.md�����������������������������������������������������������0000664�0000000�0000000�00000004303�14773033502�0020367�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Geek Radio The historical webradio, founded by David Baelde and Samuel Mimram at the ENS Lyon. The very first version was, as many other radios, a Perl function called by Ices. It played files, one by one. On the campus, there was plenty of audio files available, so they soon wanted to index them and be able to ask easily for one file to be streamed. Samuel made a dirty campus indexer in OCaml, and David made an ugly Perl hack for adding user requests to the original system. It probably kind of worked for a while. Then they wanted something more, and realized it was all too ugly. So they made the binding of libshout for OCaml and built the first streamer in pure OCaml. It had a simple telnet interface so an IRC bot could send user requests easily to it, same for the website. There were two request queues, one for users, one for admins. But it was still not so nicely designed, and they felt it when they needed more. They wanted scheduling, especially techno music at night. Around that time students had to set up a project for one of their courses. David and Samuel proposed to build a complete flexible webradio system, that's Savonet. To give jobs to everybody, they had planned a complete rewriting of every part, with grand goals. A new website with so much features, a new intelligent multilingual bot, a new network libraries for glueing that, etc. Most died. But still, Liquidsoap was born, and they had plenty of new libraries for OCaml. Since then, Liquidsoap has been greatly enhanced, and is now spreading outside the ENS Lyon. ## Features The liquidsoap script schedules several static (but periodically reloaded) playlists played on different times, adds jingle to the usual stream every hour, adds short live interventions, or completely switches to live shows when available. It accepts user requests, which have priority over static playlists but not live shows, and adds speech-synthetized metadata information at the end of requests. Geek Radio used to have a Strider daemon running to fill our database. Since that project is now dead, a simple hack is now used instead: bubble. The usual way of sending a request is via an IRC bot, which queries the database and sends the chosen URI to liquidsoap. �����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/harbor.md��������������������������������������������������������������0000664�0000000�0000000�00000011103�14773033502�0017706�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Harbor input Liquidsoap is also able to receive a source using icecast or shoutcast source protocol with the `input.harbor` operator. Using this operator, the running liquidsoap will open a network socket and wait for an incoming connection. This operator is very useful to seamlessly add live streams into your final streams: you configure the live source client to connect directly to liquidsoap, and manage the switch to and from the live inside your script. Additionally, liquidsoap can handle many simultaneous harbor sources on different ports, with finer-grained authentication schemes that can be particularly useful when used with source clients designed for the shoutcast servers. SSL support in harbor can be enabled using of of the following `opam` packages: `ssl`, `osx-secure-transport`. If enabled using `ssl`, `input.harbor.ssl` will be available. If enabled with `osx-secure-transport`, it will be `input.harbor.secure_transport`. ## Parameters The global parameters for harbor can be retrieved using `liquidsoap --list-settings`. They are: - `harbor.bind_addr`: IP address on which the HTTP stream receiver should listen. The default is `"0.0.0.0"`. You can use this parameter to restrict connections only to your LAN. - `harbor.timeout`: Timeout for source connection, in seconds. Defaults to `30.`. - `harbor.verbose`: Print password used by source clients in logs, for debugging purposes. Defaults to: `false` - `harbor.reverse_dns`: Perform reverse DNS lookup to get the client's hostname from its IP. Defaults to: `true` - `harbor.icy_formats`: Content-type (mime) of formats which allow shout (ICY) metadata update. Defaults to: ` ["audio/mpeg"; "audio/aacp"; "audio/aac"; "audio/x-aac"; "audio/wav"; "audio/wave"]` If SSL support was enabled via `ssl`, you will have the following additional settings: - `harbor.ssl.certificate`: Path to the SSL certificate. - `harbor.ssl.private_key`: Path to the SSL private key (openssl only). - `harbor.ssl.password`: Optional password to unlock the private key. Obtaining a proper SSL certificate can be tricky. You may want to start with a self-signed certificate first. You can obtain a free, valid certificate at: [https://letsencrypt.org/](https://letsencrypt.org/) If SSL support is enable via `osx-secure-transport`, you will have the same settings but named: `harbor.secure_transport.*`. To create a self-signed certificate for local testing you can use the following one-liner: ``` openssl req -x509 -newkey rsa:4096 -sha256 -nodes -keyout server.key -out server.crt -subj "/CN=localhost" -days 3650 ``` You also have per-source parameters. You can retrieve them using the command `liquidsoap -h input.harbor`. The most important one are: - `user`, `password`: set a permanent login and password for this harbor source. - `auth`: Authenticate the user according to a specific function. - `port`: Use a custom port for this input. - `icy`: Enable ICY (shoutcast) source connections. - `id`: The mountpoint registered for the source is also the id of the source. When using different ports with different harbor inputs, mountpoints are attributed per-port. Hence, there can be a harbor input with mountpoint `"foo"` on port `1356` and a harbor input with mountpoint `"foo"` on port `3567`. Additionally, if an harbor source uses custom port `n` with shoutcast (ICY) source protocol enabled, shoutcast source clients should set their connection port to `n+1`. The `auth` function is a function, that takes a record `{user, password, address}` and returns a boolean representing whether the user should be granted access or not. Typical example can be: ```{.liquidsoap include="harbor-auth.liq"} ``` In the case of the `ICY` (shoutcast) source protocol, there is no `user` parameter for the source connection. Thus, the user used will be the `user` parameter passed to the `input.harbor` source. When using a custom authentication function, in case of a `ICY` (shoutcast) connection, the function will receive this value for the username. ## Usage When using harbor inputs, you first set the required settings, as described above. Then, you define each source using `input.harbor("mountpoint")`. This source is faillible and will become available when a source client is connected. The unlabeled parameter is the mount point that the source client may connect to. It should be `"/"` for shoutcast source clients. The source client may use any of the recognized audio input codec. Hence, when using shoucast source clients, you need to have compiled liquidsoap with mp3 decoding support (`ocaml-mad`). A sample code can be: ```{.liquidsoap include="harbor-usage.liq" to=-1} ``` �������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/harbor_http.md���������������������������������������������������������0000664�0000000�0000000�00000012323�14773033502�0020752�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Harbor as HTTP server The harbor server can be used as a HTTP server. We provide two type of APIs for this: ## Simple API The `harbor.http.register.simple` function provides a simple, easy to use registration API for quick HTTP response implementation. This function receives a record describing the request and returns the HTTP response. The request passed to the function contains all expected information from the underlying HTTP query. The `data` method on a request is a _string getter_, that is a function of type: `() -> string` which returns the empty string `""` when all data has been consumed. You can use this function to e.g. write the request data to a file using `file.write.stream`. The `body` method can be used to read all of the request's data and store it in memory. Make sure to only use it if you know that the response should be small enough! For convenience, a HTTP response builder is provided via `http.response`. Here's an example: ```{.liquidsoap include="harbor.http.response.liq" from="BEGIN"} ``` where: - `port` is the port where to receive incoming connections - `method` is for the http method (or verb), one of: `"GET"`, `"PUT"`, `"POST"`, `"DELETE"`, `"OPTIONS"` and `"HEAD"` - `path` is the matched path. It can include named fragments, e.g. `"/users/:id/collabs/:cid"`. Named named fragments are passed via `request.query`, for instance: `req.query["cid"]`. ## Node/express API The `harbor.http.register` function offers a higher-level API for advanced HTTP response implementation. Its API is very similar to the node/express API. Here's an example: ```{.liquidsoap include="harbor.http.register.liq" from="BEGIN"} ``` where: - `port` is the port where to receive incoming connections - `method` is for the http method (or verb), one of: `"GET"`, `"PUT"`, `"POST"`, `"DELETE"`, `"OPTIONS"` and `"HEAD"` - `path` is the matched path. It can include named fragments, e.g. `"/users/:id/collabs/:cid"`. Matched named fragments are passed via `request.query`, for instance: `req.query["cid"]`. The handler function receives a record containing all the information about the request and fills up the details about the response, which is then used to write a proper HTTP response to the client. Named fragments from the request path are passed to the response `query` list. Middleware _a la_ node/express are also supported and registered via `http.harbor.middleware.register`. See `http.harbor.middleware.cors` for an example of how to implement one such middleware. Here's how you would enable the `cors` middleware: ``` harbor.http.middleware.register(harbor.http.middleware.cors(origin="example.com")) ``` ## Https support `https` is supported using either `libssl` or `ocaml-tls`. When compiled with either of them, a `http.transport.ssl` or `http.transport.tls` is available and can be passed to each `harbor` operator: ```liquidsoap transport = http.transport.ssl( # Server mode: required, # client mode: optional, add certificate to trusted pool certificate="/path/to/certificate/file", # Server mode: required, client mode: ignored key="/path/to/secret/key/file", # Required if key file requires one. # TLS does not support password encrypted keys! password="optional password" ) harbor.http.register(transport=transport, port=8000, ...) input.harbor(transport=..., port=8000, ...) output.harbor(transport=..., port=8000, ...) output.icecast(transport=..., port=8000, ...) ``` A given port can only support one type of transport at a time and registering handlers, sources or outputs on the same port with different transports will raise a `error.http` error. ## Advanced usage All registration functions have a `.regexp` counter part, e.g. `harbor.http.register.simple.regexp`. These function accept a full regular expression for their `path` argument. Named matches on the regular expression are also passed via the request's `query` parameter. It is also possible to directly interact with the underlying socket using the `simple` API: ```{.liquidsoap include="harbor-simple.liq"} ``` ## Examples These functions can be used to create your own HTTP interface. Some examples are: ## Redirect Icecast's pages Some source clients using the harbor may also request pages that are served by an icecast server, for instance listeners statistics. In this case, you can register the following handler: ```{.liquidsoap include="harbor-redirect.liq"} ``` ## Get metadata You can use harbor to register HTTP services to fecth/set the metadata of a source. ```{.liquidsoap include="harbor-metadata.liq" from="BEGIN"} ``` Once the script is running, a GET request for `/getmeta` at port `7000` returns the following: ``` HTTP/1.1 200 OK Content-Type: application/json; charset=utf-8 { "genre": "Soul", "album": "The Complete Stax-Volt Singles: 1959-1968 (Disc 8)", "artist": "Astors", "title": "Daddy Didn't Tell Me" } ``` ## Set metadata Using `insert_metadata`, you can register a GET handler that updates the metadata of a given source. For instance: ```{.liquidsoap include="harbor-insert-metadata.liq" from="BEGIN"} ``` Now, a request of the form `http://server:7000/setmeta?title=foo` will update the metadata of source `s` with `[("title","foo")]`. You can use this handler, for instance, in a custom HTML form. �������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/help.md����������������������������������������������������������������0000664�0000000�0000000�00000010255�14773033502�0017370�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Get help Liquidsoap is a self-documented application, which means that it can provide help about several of its aspects. You will learn here how to get help by yourself, by asking liquidsoap. If you do not succeed in asking the tool, you can of course get help from humans. We maintain the following communication channels: - Discord: [chat.liquidsoap.info](http://chat.liquidsoap.info/) - IRC: #savonet on [irc.libera.chat](https://libera.chat/) (through a discord bridge) - Mailing list: [savonet-users@lists.sourceforge.net](mailto:savonet-users@lists.sourceforge.net) ## Scripting API When scripting in liquidsoap, one uses functions that are either _builtin_ (_e.g._ `input.http` or `output.icecast`) or defined in the [script library](script_loading.html) (_e.g_ `output`). All these functions come with a documentation, that you can access by executing `liquidsoap -h FUNCTION` on the command-line. For example: ``` $ liquidsoap -h sine Generate a sine wave. Type: (?id : string?, ?amplitude : {float}, ?duration : float, ?{float}) -> source(audio=internal('a), video=internal('b), midi=internal('c)) Category: Source / Input Parameters: * id : string? (default: null) Force the value of the source ID. * amplitude : {float} (default: 1.) Maximal value of the waveform. * duration : float (default: -1.) Duration in seconds (negative means infinite). * (unlabeled) : {float} (default: 440.) Frequency of the sine. Methods: * fallible : bool Indicate if a source may fail, i.e. may not be ready to stream. * id : () -> string Identifier of the source. * is_active : () -> bool `true` if the source is active, i.e. it is continuously animated by its own clock whenever it is ready. Typically, `true` for outputs and sources such as `input.http`. * is_ready : () -> bool Indicate if a source is ready to stream. This does not mean that the source is currently streaming, just that its resources are all properly initialized. * is_up : () -> bool Indicate that the source can be asked to produce some data at any time. This is `true` when the source is currently being used or if it could be used at any time, typically inside a `switch` or `fallback`. * on_leave : ((() -> unit)) -> unit Register a function to be called when source is not used anymore by another source. * on_metadata : ((([string * string]) -> unit)) -> unit Call a given handler on metadata packets. * on_shutdown : ((() -> unit)) -> unit Register a function to be called when source shuts down. * on_track : ((([string * string]) -> unit)) -> unit Call a given handler on new tracks. * remaining : () -> float Estimation of remaining time in the current track. * seek : (float) -> float Seek forward, in seconds (returns the amount of time effectively seeked). * self_sync : () -> bool Is the source currently controlling its own real-time loop. * skip : () -> unit Skip to the next track. * time : () -> float Get a source's time, based on its assigned clock. ``` Of course if you do not know what function you need, you'd better go through the [API reference](reference.html). Please note that some functions in that list are optional and may not be available with your local `liquidsoap` install unless you install the optional dependency that enables it. The list of optional dependencies is listed via `opam info liquidsoap` if you have installed it this way or can in our [build page](build.html). ## Settings Liquidsoap scripts contain expression like `settings.log.stdout := true`. These are _settings_, global variables affecting the behaviour of the application. Some common settings have shortcut for convenience. These are all shortcuts to their respective `settings` values: ```{.liquidsoap include="settings.liq"} ``` You can have a list of available settings, with their documentation, by running `liquidsoap --list-settings`. The output of these commands is a valid liquidsoap script, which you can edit to set the values that you want, and load it ([implicitly](script_loading.html) or not) before you other scripts. You can browse online the [list of available settings](settings.html). ���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/hls_output.md����������������������������������������������������������0000664�0000000�0000000�00000011021�14773033502�0020636�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# HLS Output Starting with liquidsoap `1.4.0`, it is possible to send your streams as [HLS output](https://en.wikipedia.org/wiki/HTTP_Live_Streaming). The main operator is `output.file.hls`. Here's an example using it, courtesy of [srt2hls](https://github.com/mbugeia/srt2hls): ```{.liquidsoap include="output.file.hls.liq"} ``` Let's see what's important here: - `streams` describes the encoded streams. It's a list of: `(stream_name, encoder)`. `stream_name` is used to generate the corresponding media playlists. Encoders can be any encoder supported by liquidsoap. However, the [HLS RFC](https://tools.ietf.org/html/rfc8216) limits the list of possible codecs to `mp3` and `aac`. Furthermore, for the best possible compatible, it is recommended to send data encapsulated in a `MPEG-TS` stream. Currently, the only encoder capable of doing this in liquidsoap is `%ffmpeg`. - `persist_at` is used to allow liquidsoap to restart while keeping the existing segments and playlists. When shutting down, liquidsoap stores the current configuration at `persist_at` and uses it to restart the HLS stream when restarting. - `segments` and `segments_overhead` are used to keep track of the generated segments. Each media playlist will contain a number of segments defined by `segments` and an extra set of segments, defined by `segments_overhead`, is kept past the playlist size for those listeners who are still listening on outdated segments. There are more useful options, in particular `on_file_change`, which can be used for instance to sync up your segments and playlists to a distant storage and hosting service such as S3. Liquidsoap also provides `output.harbor.hls` which allows to serve HLS streams directly from liquidsoap. Their options should be the same as `output.file.hls`, except for harbor-specifc options `port` and `path`. It is not recommended for listener-facing setup but can be useful to sync up with a caching system such as cloudfront. ## Keyframes and segment length In codec terminology, a `keyframe` can be understood as a piece of encoded data that contains enough information to start decoding the stream. Keyframes are very common in video codecs and can exist in audio codecs. In order to make sure that a HLS playlist can be decoded starting from any segment, liquidsoap tries to split segments on keyframe boundaries. When not possible, you will see a warning in the logs. Segment split is forced when reaching the value specified by `EXT-X-TARGETDURATION` to follow the HLS specifications. For metadata and extra tags, segment split will occur at the next keyframe. To make sure that all these requirements operate correctly, you should make sure to set a keyframe frequency in your encoder's settings that generates at lease one keyframe per segment. For instance, if your segments are at most `2s` long and encoded using `libx264`, you can use the `keyint` and `keyint-min` parameters, which are expressed in number of frames. If your video frame rate is `25fps` (liquidsoap's default), you should have at least one keyframe every `2 * 25 = 50` frames. ```liquidsoap %ffmpeg( ..., %video(codec="libx264", x264opts="keyint=50:min-keyint=50") ) ``` ## Metadata HLS outputs supports metadata in two ways: - Using the `%ffmpeg` encoder, through a `timed_id3` metadata logical stream with the `mpegts` format. - Through regular ID3 frames, as requested by the [HLS specifications](https://datatracker.ietf.org/doc/html/rfc8216#section-3.4) for `adts`, `mp3`, `ac3` and `eac3` formats with the `%ffmpeg` encoder and also natively using the `%mp3`, `%shine` or `%fdkaac` encoders. - There is currently no support for in-stream metadata for the `mp4` format. Metadata parameters are passed through the record methods of the streams' encoders. Here's an example ```{.liquidsoap include="hls-metadata.liq"} ``` Parameters are: - `id3`: Set to `false` to deactivate metadata on the streams. Defaults to `true`. - `id3_version`: Set the `id3v2` version used to export metadata - `replay_id3`: By default, the latest metadata is inserted at the beginning of each segment to make sure new listeners always get the latest metadata. Set to `false` to disable it. Metadata for these formats are activated by default. If you are experiencing any issues with them, you can disable them by setting `id3` to `false`. ## Mp4 format `mp4` container is supported by requires specific parameters. Here's an example that mixes `aac` and `flac` audio, The parameters required for `mp4` are `movflags` and `frag_duration`. ```{.liquidsoap include="hls-mp4.liq"} ``` ���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/http_input.md����������������������������������������������������������0000664�0000000�0000000�00000001171�14773033502�0020633�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# HTTP input Liquidsoap can create a source that pulls its data from an HTTP location. This location can be a distant file or playlist, or an icecast or shoutcast stream. To use it in your script, simply create a source that way: ```{.liquidsoap include="http-input.liq" from="BEGIN" to="END"} ``` This operator will pull regularly the given location for its data, so it should be used for locations that are assumed to be available most of the time. If not, it might generate unnecessary traffic and pollute the logs. In this case, it is perhaps better to inverse the paradigm and use the [input.harbor](harbor.html) operator. �������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/icy_metadata.md��������������������������������������������������������0000664�0000000�0000000�00000004253�14773033502�0021065�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# ICY metadata _ICY metadata_ is the name for the mechanism used to update metadata in icecast's source streams. The techniques is primarily intended for data formats that do not support in-stream metadata, such as mp3 or AAC. However, it appears that icecast also supports ICY metadata update for ogg/vorbis streams. When using the ICY metadata update mechanism, new metadata are submitted separately from the stream's data, via a http GET request. The format of the request depends on the protocol you are using (ICY for shoutcast and icecast 1 or HTTP for icecast 2). Starting with 1.0, you can do several interesting things with icy metadata updates in liquidsoap. We list some of those here. ## Enable/disable ICY metadata updates You can enable or disable icy metadata update in `output.icecast` by setting the `send_icy_metadata` parameter to `null()`, `true` or `false`. The default value is `null()` and does the following: - Set `true` for: mp3, aac, aac+, wav - Set `false` for any format using the ogg container In some cases, `liquidsoap` might not be able to detect if ICY metadata need to be enabled, in which case it will ask you to set a `true` or `false` value for this parameter. ## `song` metadata Most Icecast listeners expect a `song` metadata to be generated. This metadata should combine both artist and title metadata and will be played preferably. We provide a default implementation that returns `artist` or `title` metadata when only one of these two is available and `$(artist) - $(title)` otherwise. You can use the `icy_song` parameter to use your own implementation. Returning `null()` from that function disables the metadata altogether. ## Update metadata manually The function `icy.update_metadata` implements a manual metadata update using the ICY mechanism. It can be used independently from the `icy_metadata` parameter described above, provided icecast supports ICY metadata for the intended stream. For instance the following script registers a telnet command name `metadata.update` that can be used to manually update metadata: ```{.liquidsoap include="icy-update.liq"} ``` As usual, `liquidsoap -h icy.update_metadata` lists all the arguments of the function. �����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/images�����������������������������������������������������������������0000777�0000000�0000000�00000000000�14773033502�0021641�2../orig/images��������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/in_production.md�������������������������������������������������������0000664�0000000�0000000�00000001660�14773033502�0021314�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Using in production The full installation of liquidsoap will typically install `/etc/liquidsoap`, `/etc/init.d/liquidsoap` and `/var/log/liquidsoap`. All these are meant for a particular usage of liquidsoap when running a stable radio. Your production `.liq` files should go in `/etc/liquidsoap`. You'll then start/stop them using the init script, _e.g._ `/etc/init.d/liquidsoap start`. Your scripts don't need to have the `#!` line, and liquidsoap will automatically be ran on daemon mode (`-d` option) for them. You should not override the `log.file.path` setting because a logrotate configuration is also installed so that log files in the standard directory are truncated and compressed if they grow too big. It is not very convenient to detect errors when using the init script. We advise users to check their scripts after modification (use `liquidsoap --check /etc/liquidsoap/script.liq`) before effectively restarting the daemon. ��������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/index.md���������������������������������������������������������������0000664�0000000�0000000�00000010160�14773033502�0017542�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Liquidsoap Liquidsoap is a powerful tool for building complex audio and video stream generators, typically targeting internet radios and webtvs. It consists of a simple script language, which has a first-class notion of source (basically a _stream_) and provides elementary source constructors and source compositions from which you can build the stream generator you want. This design makes liquidsoap flexible and easily extensible. We believe that liquidsoap is easy to use. For basic purposes, the scripts consist of the definition of a tree of sources. You will quickly [learn](quick_start.html) how natural it is to use liquidsoap in such cases. The good thing is that when you'll want to make your stream more complex, you'll be able to stay in the same framework and keep a maintainable configuration. Of course, using some complex features might require a deeper understanding of the concepts of [source](sources.html) and [request](requests.html) and of our [scripting language](language.html). We'll discuss below what liquidsoap is and what it isn't. If you're already familiar with it and want to get started, just jump to the [documentation index](documentation.html). It will provide guidance,starting with the [quickstart tour](quick_start.html). Liquidsoap is an open-source software from the [Savonet](http://liquidsoap.info) project. ## Features Here are a few things you can easily achieve using Liquidsoap: - Playing from files, playlists, directories or script playlists (plays the file chosen by an external program). - [Video streams](video.html) generation. - Decoding/encoding using any media format supported by FFmpeg. - Transcoding of media stream, relay of encoded media stream without re-encoding, sharing encoding to avoid encoding multiple times. - Transparent remote file access; easy addition of file resolution protocols. - Scheduling of many sources, depending on time, priorities, quotas, etc. - Mixing sources on top others. - Queuing of user requests; editable queues. - Sound processing: compression, normalization, echo, soundtouch, etc. - Speech and sound synthesis. - [Metadata](metadata.html) rewriting and insertion. - Arbitrary transitions: cross-fade, jingle insertion, custom, etc. The behaviour of the transition can be programmed to depend on metadata and average volume. - [Input of other streams](http_input.html): useful for switching to a live show. Liquidsoap can relay an HTTP stream but also host it. - [Blank detection](blank.html). - Definable event handlers on new tracks, new metadata and excessive blank. - Multiple outputs in the same instance: you can have several quality settings, use several media or even broadcast several contents from the same instance. - Output to HLS/Icecast/Shoutcast (MP3/Ogg) or a local file (WAV/MP3/Ogg/AAC). - Input/output via Jack, ALSA, OSS and PortAudio. Output via `libao`. - [Interactive control](advanced.html) of many operators via Telnet or UNIX domain socket, and indirectly using scripts, graphical/web/IRC interfaces. If you need something else, it's highly possible that you can have it -- at least by programming new sources/operators. Send us a request, we'll be happy to discuss these questions. ## Non-Features Liquidsoap is a flexible tool for processing audio and video streams, that's all. We've used it for several internet radio projects, and we know its flexibility is useful. However, internet radio usually requires more than just an audio stream, as such components cannot easily be built from basic primitives as we do in liquidsoap for streams. We don't have any magic solution for these, although we sometimes have some nice tools which could be adapted to various uses. Liquidsoap itself doesn't have a nice GUI or any graphical programming environment. You'll have to write the script by hand, and the only possible interaction with a running liquidsoap is the telnet server. Liquidsoap makes the interfacing with other tools easy, since it can call an external application (reading from the database) to get audio tracks, another one (updating last-played information) to notify that some file has been successfully played. An example of this is [Beets](beets.html). ����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/install.md�������������������������������������������������������������0000664�0000000�0000000�00000012124�14773033502�0020103�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Installing Liquidsoap You can install liquidsoap using binary builds, with OPAM or from source. Binary builds are provided with our releases, either in the form of debian/ubuntu and alpine packages or as docker images (also for debian or alpine). Your favorite distribution may also have binary packages. The binary package and docker images we provide are compiled in two flavors: - The main `liquidsoap` packages are compiled with all available features and functions. This is a good starting point for general-purpose development - Binary packages and docker images labelled `-minimal` are compiled without the extra libraries and with a limited set of essential optional features Minimal builds are useful if you are concerned about size or memory usage. They also reduce the chances of running into issues that could be introduced by optional dependencies that you do not use. If your script works with them, they are recommended over the fully featured builds for production. Each binary build that we provide have a corresponding `*.config` file. This is a text file that lists all the features included in a specific build. You can consult it to know what features are available. You can also get the same information by calling `liquidsoap --build-config`, for instance when using a docker image. Binary packages and docker images are useful in that they provide a readily available liquidsoap installation. If you need more finer-grained build or if your distribution/OS does not have a binary build, you can install via OPAM, which is a very convenient package manager that can compile liquidsoap from sources and knows how to handle external dependencies for most OS/distributions. Lastly, compiling from source should be reserved to developers. - [Debian/Ubuntu](#debianubuntu) - [Alpine](#alpine) - [Docker](#docker) - [Windows](#windows) - [Using OPAM](#install-using-opam) - [From source](#installing-from-source) ## Debian/Ubuntu We generate debian and ubuntu packages automatically as part of our [release process](https://github.com/savonet/liquidsoap/releases). Otherwise, you can check out the official [debian](https://packages.debian.org/liquidsoap) and [ubuntu](https://packages.ubuntu.com/liquidsoap) packages. ## Alpine Alpine packages are also provided as part of our [release process](https://github.com/savonet/liquidsoap/releases). ## Docker We provide production-ready docker images via [Docker hub](https://hub.docker.com/r/savonet/liquidsoap). Docker images are tagged with a release tag (e.g. `v2.1.4`) and with the sha of their git commit (e.g. `a24bf49`). For instance, to fetch release `2.3.1`, you would do: ```shell docker pull savonet/liquidsoap:v2.3.1 ``` Please note that images tagged with a release tag may change while images tagged with a commit sha will not. ## Windows You can download a liquidsoap for windows from our [release page](https://github.com/savonet/liquidsoap/releases). ## Install using OPAM The recommended method to install liquidsoap from source is by using the [OCaml Package Manager](http://opam.ocaml.org/). OPAM is available in all major distributions and on windows. We actively support the liquidsoap packages there and its dependencies. You can read [here](https://opam.ocaml.org/doc/Usage.html) about how to use OPAM. In order to use it: - [you should have at least OPAM version 2.1](https://opam.ocaml.org/doc/Install.html), - not all version of the OCaml compiler are supported. You can run `opam info liquidsoap-lang` to find out. You can create a switch for a specific OCaml version as follows: ``` opam switch create <ocaml version> ``` A typical installation with most expected features is done by executing: ``` opam install ffmpeg liquidsoap ``` This will install `liquidsoap` along with the optional `ffmpeg` package, which provides most of the expected functionalities (encoding, decoding, metadata support etc) out of the box. The `opam` installer also handles external dependencies that is, dependencies from your operating system that are required for your install. Typically, this would be the `ffmpeg` shared libraries here, as well as `libcurl`, which is required for `liquidsoap` to install. In most cases, `opam` will simply ask for your permission to install these dependencies on your behalf. In some cases, however, you will have install them yourself. Most of liquidsoap's dependencies are only optional. For instance, if you want to enable opus encoding and decoding after you've already installed liquidsoap, you should execute the following: ``` opam install opus ``` This will install `opus` and its dependencies and recompile `liquidsoap` to take advantage of it. `opam info liquidsoap` should give you the list of all optional dependencies that you may enable in liquidsoap. **Note** `opam` handles external dependencies via your system's packaging. In order to build some of the associated OCaml modules, macos users using `homebrew` might need to add the following to their environment/shell configuration: ```shell export CPATH=/opt/homebrew/include export LIBRARY_PATH=/opt/homebrew/lib ``` ## Installing from source See the [build instructions](build.html) ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/json.md����������������������������������������������������������������0000664�0000000�0000000�00000021257�14773033502�0017415�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������## Importing JSON values _Note:_ If you are reading this page for the first time, you might want to skip directly to the explicit type annotation below as this is the recommended way of parsing JSON data. The content before that is here to explain the inner workings of JSON parsing in `liquidsoap`. Liquidsoap supports importing JSON values through a special `let` syntax. Using this syntax makes it relatively natural to parse JSON data in your script while keeping type-safety at runtime. Here's an example: ```{.liquidsoap include="json1.liq"} ``` This prints: ``` We parsed a JSON object and got value abc for attribute foo! ``` What happened here is that liquidsoap kept track of the fact that `v` was called with `v.foo` and that the result of that was a string. Then, at runtime, it checks the parsed JSON value against this type and raises an issue if that did not match. For instance, the following script: ```liquidsoap let json.parse v = '{"foo": 123}' print("We parsed a JSON object and got value " ^ v.foo ^ " for attribute foo!") ``` raises the following exception: ``` Error 14: Uncaught runtime error: type: json, message: "Parsing error: json value cannot be parsed as type {foo: string, _}" ``` Of course, this all seems pretty trivial presented like that but, let's switch to reading a file instead: ```liquidsoap let json.parse v = file.contents("/path/to/file.json") print("We parsed a JSON object and got value " ^ v.foo ^ " for attribute foo!") ``` Now, this is getting somewhere! Let's push it further and parse a whole `package.json` from a typical `npm` package: ```liquidsoap # Content of package.json is: # { # "name": "my_package", # "version": "1.0.0", # "scripts": { # "test": "echo \"Error: no test specified\" && exit 1" # }, # ... let json.parse package = file.contents("/path/to/package.json") name = package.name version = package.version test = package.scripts.test print("This is package " ^ name ^ ", version " ^ version ^ " with test script: " ^ test) ``` And we get: ``` This is package my_package, version 1.0.0 with test script: echo "Error: no test specified" && exit 1 ``` This can even be combined with _patterns_: ```liquidsoap let json.parse { name, version, scripts = { test } } = file.contents("/path/to/package.json") print("This is package " ^ name ^ ", version " ^ version ^ " with test script: " ^ test) ``` Now, this is looking nice! ## Explicit type annotation Explicit type annotation are the recommended way to parse JSON data. Let's try a slight variation of the previous script now: ```liquidsoap let json.parse { name, version, scripts = { test } } = file.contents("/path/to/package.json") print("This is package #{name}, version #{version} with test script: #{test}") ``` This returns: ``` This is package null, version null with test script: null ``` What? 🤔 This is because, in this script, we only use `name`, `version`, etc.. through the interpolation syntax `#{...}`. However, interpolated variables can be anything so this does not leave enough information to the typing system to know what type those variables should be and, in this case, we default to `null`. In order to avoid bad surprises like this, it is usually recommended to add **type annotations** to your json parsing call to explicitly state what kind of data you are expecting. Let's add one here: ```liquidsoap let json.parse ({ name, version, scripts = { test } } : { name: string, version: string, scripts: { test: string } }) = file.contents("/path/to/package.json") print("This is package #{name}, version #{version} with test script: #{test}") ``` And we get: ``` This is package my_package, version 1.0.0 with test script: echo "Error: no test specified" && exit 1 ``` Back to normal! ### Type syntax The syntax for type annotation is as follows: #### Ground types `string`, `int`, `float` are parsed as, resp., a string, an integer or a floating point number. Note that if your json value contains an integer such as `123`, parsing it as a floating point number will succeed. Also, if an integer is too big to be represented as an `int` internally, it will be parsed as a floating point number. #### Nullable types All type annotation can be postfixed with a trailing `?` to denote a _nullable_ value. If a type is nullable, the json parser will return `null` when it cannot parse the value as the principal type. This is particularly useful when you are not sure of all the types that you are parsing. For instance, some `npm` packages do not have a `scripts` entry or a `test` entry, so you would parse them as: ```liquidsoap let json.parse ({ name, version, scripts, } : { name: string, version: string, scripts: { test: string? }? }) = file.contents("/path/to/package.json") ``` And, later, inspect the returned value to see if it is in fact present. You can do it in several ways: ```liquidsoap # Check if the value is defined: test = if null.defined(scripts) then null.get(scripts.test) else null () end # Use the ?? syntax: test = (scripts ?? { test = null() }).test ``` #### Tuple types The type `(int * float * string)` tells liquidsoap to parse a JSON array whose _first values_ are of type: `int`, `float` and `string`. If any further values are present in the array, they will be ignored. For arrays as well as any other structured types, the special notation `_` can be used to denote any type. For instance, `(_ * _ * float)` denotes an JSON array whose first 2 elements can be of any type and its third element is a floating point number. #### Lists The type `[int]` tells liquidsoap to parse a JSON array where _all its values_ are integers as a list of integers. If you are not sure if all elements in the array are integers, you can always use nullable integers: `[int?]` #### Objects The type `{foo: int}` tells liquidsoap to parse a JSON object as a record with an attribute labelled `foo` whose value is an integer. All other attributes are ignored. Arbitrary object keys can be parsed using the following syntax: `{"foo bar key" as foo_bar_key: int}`, which tells liquidsoap to parse a JSON object as a record with an attribute labelled `foo_bar_key` which maps to the attribute `"foo bar key"` from the JSON object. #### Associative lists as objects It can sometimes be useful to parse a JSON object as an associative list, for instance if you do not know in advance all the possible keys of an object. In this case, you can use the special type: `[(string * int)] as json.object`. This tells liquidsoap to parse the JSON object as a list of pairs `(string * int)` where `string` represents the attribute label and `int` represent the attribute value. If you are not sure if all the object values are integers you can always use nullable integers: `[(string * int?)] as json.object` ### Parsing errors When parsing fails, a `error.json` is raised which can be caught at runtime: ```liquidsoap try let json.parse ({ status, data = { track } } : { status: string, data: { track: string } }) = res # Do something on success here.. catch err: [error.json] do # Do something on parse errors here.. end ``` #### Example Here's a full example. Feel free to refer to `tests/language/json.liq` in the source code for more of them. ```{.liquidsoap include="json-ex.liq"} ``` It returns ``` - x : { foo = 34.24, gni_gno = true, nested = { tuple = (null, 3.14), list = [44., 55., 66.12], nullable_list = [null, 23, null], object_as_list = [("foo", 123.), ("gni", 456.0), ("gno", 3.14)], arbitrary_object_key = true, not_present = null } } ``` ### JSON5 extension Liquidsoap supports the [JSON5](https://json5.org/) extension. Parsing of `json5` values is enabled with the following argument: ```liquidsoap let json.parse[json5=true] x = ... ``` If a `json5` variable is in scope, you can also simply use `let json.parse[json5] x = ...` ## Exporting JSON values Exporting JSON values can be done using the `json.stringify` function: ```{.liquidsoap include="json-stringify.liq"} ``` Please note that not all values are exportable as JSON, for instance function. In such cases the function will raise an `error.json` exception. ## Generic JSON objects Generic `JSON` objects can be manipulated through the `json()` operator. This operator returns an opaque json variable with methods to `add` and `remove` attributes: ```liquidsoap j = json() j.add("foo", 1) j.add("bla", "bar") j.add("baz", 3.14) j.add("key_with_methods", "value".{method = 123}) j.add("record", { a = 1, b = "ert"}) j.remove("foo") s = json.stringify(j) - s: '{ "record": { "b": "ert", "a": 1 }, "key_with_methods": "value", "bla": "bar", "baz": 3.14 }' ``` �������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/ladspa.md��������������������������������������������������������������0000664�0000000�0000000�00000003672�14773033502�0017711�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# LADSPA plugins in Liquidsoap [LADSPA](http://www.ladspa.org/) is a standard that allows software audio processors and effects to be plugged into a wide range of audio synthesis and recording packages. If enabled, Liquidsoap supports LADSPA plugins. In this case, installed plugins are detected at run-time and are all available in Liquidsoap under a name of the form: `ladspa.plugin`, for instance `ladspa.karaoke`, `ladspa.flanger` etc.. The full list of those operators can be found using `liquidsoap --list-plugins`. Also, as usual, `liquidsoap -h ladspa.plugin` returns a detailed description of each LADSPA's operators. For instance: ``` ./liquidsoap -h ladspa.flanger *** One entry in scripting values: Flanger by Steve Harris <steve@plugin.org.uk>. Category: Source / Sound Processing Type: (?id:string,?delay_base:'a,?feedback:'b, ?lfo_frequency:'c,?max_slowdown:'d, source(audio='#e,video='#f,midi='#g))-> source(audio='#e,video='#f,midi='#g) where 'a, 'b, 'c, 'd is either float or ()->float Flag: hidden Parameters: * id : string (default "") Force the value of the source ID. * delay_base : anything that is either float or ()->float (default 6.32499980927) Delay base (ms) (0.1 <= delay_base <= 25). * feedback : anything that is either float or ()->float (default 0.)

This means that those parameters may be dynamically changed while running a liquidsoap script. ����������������������������������������������������������������������liquidsoap-2.3.2/doc/content/language.md������������������������������������������������������������0000664�0000000�0000000�00000140067�14773033502�0020230�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Liquidsoap's scripting language _The following is adapted from the [Liquidsoap book](book.html). The reader is avised to check out the whole chapter in the book for more details about the liquidsoap language_ ## General features Liquidsoap is a novel language which was designed from scratch to handle media stream. It takes some inspiration from functional languages such as [OCaml](https://ocaml.org/) but features a syntax that is more intuitive to the general purpose programmer, similar to Ruby or Javascript. ### Typing One of the main features of the language is that it is _typed_. This means that every expression belongs to some type which indicates what it is. For instance, `"hello"` is a _string_ whereas `23` is an _integer_, and, when presenting a construction of the language, we will always indicate the associated type. Liquidsoap implements a _typechecking_ algorithm which ensures that whenever a string is expected a string will actually be given, and similarly for other types. This is done without running the program, so that it does not depend on some dynamic tests, but is rather enforced by theoretical considerations. Another distinguishing feature of this algorithm is that it also performs _type inference_: you never actually have to write a type, those are guessed automatically by Liquidsoap. This makes the language very safe, while remaining very easy to use. ### Functional programming The language is _functional_, which means that you can very easily define functions, and that functions can be passed as arguments of other functions. This might look like a crazy thing at first, but it is actually quite common in some language communities (such as OCaml). It also might look quite useless: why should we need such functions when describing webradios? You will soon discover that it happens to be quite convenient in many places: for handlers (we can specify the function which describes what to do when some event occurs such as when a DJ connects to the radio), for transitions (we pass a function which describes the shape we want for the transition) and so on. ### Streams The unique feature of Liquidsoap is that it allows the manipulation of _sources_ which are functions which will generate streams. These streams typically consist of stereo audio data, but we do restrict to this: they can contain audio with arbitrary number of channels, they can also contain an arbitrary number of video channels, and also MIDI channels (there is limited support for sound synthesis). ### Standard library Although the core of Liquidsoap is written in OCaml, many of the functions of Liquidsoap are written in the Liquidsoap language itself. Those are defined in the `stdlib.liq` script, which is loaded by default and includes all the libraries. You should not be frightened to have a look at the standard library, it is often useful to better grasp the language, learn design patterns and tricks, and add functionalities. Its location on your system is indicated in the variable `configure.libdir` and can be obtained by typing ## Basic values ### Integers and floats The _integers_, such as `3` or `42`, are of type `int`. Depending on the current architecture of the computer on which we are executing the script (32 or 64 bits, the latter being the most common nowadays) they are stored on 31 or 63 bits. The minimal (resp. maximal) representable integer can be obtained as the constant `min_int` (resp. `max_int`); typically, on a 64 bits architecture, they range from -4611686018427387904 to 4611686018427387903. The _floating point numbers_, such as `2.45`, are of type `float`, and are in double precision, meaning that they are always stored on 64 bits. We always write a decimal point in them, so that `3` and `3.` are not the same thing: the former is an integer and the latter is a float. This is a source of errors for beginners, but is necessary for typing to work well. ### Strings Strings are written between double or single quotes, e.g. `"hello!"` or `'hello!'`, and are of type `string`. In order to write the character "`"`" in a string, one cannot simply type "`"`" since this is already used to indicate the boundaries of a string: this character should be _escaped_, which means that the character "`\`" should be typed first so that ```liquidsoap print("My name is \"Sam\"!") ``` will actually display "`My name is "Sam"!`". Other commonly used escaped characters are "`\\`" for backslash and "`\n`" for new line. Alternatively, one can use the single quote notation, so that previous example can also be written as ```liquidsoap print('My name is "Sam"!') ``` This is most often used when testing JSON data which can contain many quotes or for command line arguments when calling external scripts. The character "`\`" can also be used at the end of the string to break long strings in scripts without actually inserting newlines in the strings. For instance, the script ```liquidsoap print("His name is \ Romain.") ``` will actually print ``` His name is Romain. ``` Note that there is no line change between "is" and "Romain", and the indentation before "Romain" is not shown either. The concatenation of two strings is achieved by the infix operator "`^`", as in ```liquidsoap user = "dj" print("Current user is " ^ user) ``` Instead of using concatenation, it is often rather convenient to use _string interpolation_: in a string, `#{e}` is replaced by the string representation of the result of the evaluation of the expression `e`: ```liquidsoap user = "admin" print("The user #{user} has just logged.") ``` will print `The user admin has just logged.` or ```liquidsoap print("The number #{random.float()} is random.") ``` will print `The number 0.663455738438 is random.` (at least it did last time I tried). #### Escaping strings Liquidsoap strings follow the most common lexical conventions from `C` and `javascript` and `JSON`, in particular, `string.unescape` recognizes the same escape sequences as `C` (except for `UTF-16` characters) and javascript. The following sequences are recognized: | Escape sequence | Hex value in ASCII | Character represented | | --------------- | ------------------ | ------------------------------------------------------------------------------------- | | `\a` | `\x07` | Alert (Beep, Bell) | | `\b` | `\x08` | Backspace | | `\e` | `\x1B` | Escape character | | `\f` | `\x0C` | Formfeed, Page Break | | `\n` | `\x0A` | Newline (Line Feed) | | `\r` | `\x0D` | Carriage Return | | `\t` | `\x09` | Horizontal Tab | | `\v` | `\x0B` | Vertical Tab | | `\\` | `\x5C` | Backslash | | `\/` | `\x2f` | Forward slash | | `\'` | `\x27` | Apostrophe or single quotation mark | | `\"` | `\x22` | Double quotation mark | | `\?` | `\x3F` | Question mark (used to avoid Digraphs and trigraphs) | | `\nnn` | any | The byte whose numerical value is given by _nnn_ interpreted as an _octal_ number | | `\xhh` | any | The byte whose numerical value is given by _hh_ interpreted as a _hexadecimal_ number | | `\uhhhh` | none | UTF8-8 code point given by _hhhh_ interpreted as an _hexadecimal_ number | This convention has been decided to follow the most common practices. In particular, `\nnn` is an _octal_ escape sequence in most languages including C, Ruby, Javascript, Python and more. This differs from OCaml where `\nnn` is considered a _digital_ escape sequence. These lexical conventions are used in the default `string.escape` and `string.unescape`. Here's an example of an escaped string: ``` # "\" \t \045 \x2f \u4f32";; - : string = "\" \t % / 2" ``` The function `string.quote` returns [JSON-compatible](https://www.json.org/json-en.html) strings. ### Regular expressions _This feature was introduced in liquidsoap version 2.1.0_ Regular expressions can be created using the `regexp` operator or the syntactic sugar: `r/.../<flags>`. For instance: ```liquidsoap # Using the regexp operator: r = regexp(flags=["g","i"], "foo([\\w])+bar") # Using the r/../ syntactic sugar: r = r/foo([\w])bar/gi ``` Using the `r/../` syntactic sugar makes it possible to write regular expressions without having to escape `\` characters, which makes them more easily readable. Regular expression flags are: - `i`: perform case-insensitive match - `g`: substitute all matched sub-strings, not just the first one - `s`: match all characters, including `\n` when using the `.` pattern - `m`: `^` and `$` match before/after newlines, not just at the beginning/end of a string Regular expressions have the following methods: - `replace(fn, s)`: replace matched substrings of `s` using function `fn`. If the `g` flag is not passed, only the first match is replaced otherwise, all matches are replaced - `split(s)`: split the given string on all substrings matching the regular expression. - `test(s)`: returns `true` if the given string matches the regular expression. - `exec(s)`: execute the regular expression and return a of list matches of the form: `[(<match index>, <match>), ..]`. Named matches are also supported and returned as property `groups` of type `[string * string]`: ```liquidsoap r/(foo)(?<gno>gni)?/g.exec("foogni") - : [int * string].{groups : [string * string]} = [ (2, "gni"), (1, "foo"), (0, "foogni") ].{ groups = [ ("gno", "gni") ] } ``` ### Booleans The _booleans_ are either `true` or `false` and are of type `bool`. They can be combined using the usual boolean operations - `and`: conjunction, - `or`: disjunction, - `not`: negation. Booleans typically originate from comparison operators, which take two values and return booleans: - `==`: compares for equality, - `!=`: compares for inequality, - `<=`: compares for inequality, and so on (`<`, `>=`, `>`). For instance, the following is a boolean expression: ```liquidsoap (n < 3) and not (s == "hello") ``` _Conditional branchings_ execute code depending on whether a condition is true or not. For instance, the code ```liquidsoap if (1 <= x and x <= 12) or (not 10h-15h) then print("The condition is satisfied") else print("The condition ain't satisfied") end ``` will print that the condition is satisfied when either `x` is between 1 and 12 or the current time is not between 10h and 15h. A conditional branching might return a value, which is the last computed value in the chosen branch. For instance, ```liquidsoap y = if x < 3 then "A" else "B" end ``` will assign `"A"` or `"B"` to `y` depending on whether `x` is below 3 or not. The two branches of a conditional should always have the same return type: ```liquidsoap x = if 1 == 2 then "A" else 5 end ``` will result in ``` At line 1, char 19-21: Error 5: this value has type string but it should be a subtype of int ``` meaning that `"A"` is a string but is expected to be an integer because the second branch returns an integer, and the two should be of same nature. The `else` branch is optional, in which case the `then` branch should be of type `unit`: ```liquidsoap if x == "admin" then print("Welcome admin") end ``` In the case where you want to perform a conditional branching in the `else` branch, the `elsif`{.liquidsoap} keyword should be used, as in the following example, which assigns 0, 1, 2 or 3 to `s` depending on whether `x` is `"a"`, `"b"`, `"c"` or something else: ```liquidsoap s = if x == "a" then 0 elsif x == "b" then 1 elsif x == "c" then 2 else 3 end ``` This is equivalent (but shorter to write) to the following sequence of imbricated conditional branchings: ```liquidsoap s = if x == "a" then 0 else if x == "b" then 1 else if x == "c" then 2 else 3 end end end ``` Finally, we should mention that the notation `c?a:b` is also available as a shorthand for `if c then a else b end`, so that the expression ```liquidsoap y = if x < 3 then "A" else "B" end ``` can be shortened to ```liquidsoap y = (x<3)?"A":"B" ``` (and people will think that you are a cool guy). #### Time predicates Time predicates are special boolean values such as `{0h-7h}`. These values are `true` or `false` depending on the current time. Some examples of time predicates are --- `{11h15-13h}` between 11h15 and 13h `{12h}` between 12h00 and 12h59 `{12h00}` at 12h00 `{00m}` on the first minute of every hour `{00m-09m}` on the first 10 minutes of every hour `{2w}` on Tuesday `{6w-7w}` on weekends --- Above, `w` stands for weekday: 1 is Monday, 2 is Tuesday, and so on. Sunday is both 0 and 7. Time predicate can also be parsed at runtime, for instance if you want to create them dynamically. The syntax is: ```liquidsoap # f = time.predicate("00m-30m");; f : () -> bool = <fun> ``` Be aware that, if parsing fails, it will raise `error.string`: ```liquidsoap # f = time.predicate("foo") Error 14: Uncaught runtime error: type: string, message: "Failed to parse foo as time predicate" ``` ### Unit Some functions, such as `print`, do not return a meaningful value: we are interested in what they are doing (e.g. printing on the standard output) and not in their result. However, since typing requires that everything returns something of some type, there is a particular type for the return of such functions: `unit`. Just as there are only two values in the booleans (`true` and `false`), there is only one value in the unit type, which is written `()`. This value can be thought of as the result of the expression saying "I'm done". ### Lists Some more elaborate values can be constructed by combining the previous ones. A first kind is _lists_ which are finite sequences of values, being all of the same type. They are constructed by square bracketing the sequence whose elements are separated by commas. For instance, the list ```liquidsoap [1, 4, 5] ``` is a list of three integers (1, 4 and 5), and its type is `[int]`, and the type of `["A", "B"]` would obviously be `[string]`. Note that a list can be empty: `[]`. You can extract list elements through _splats_ such as ```liquidsoap l = [1, 5, 7, 8, 9] let [x, _, z, ...t] = l ``` In this example, the value of `x` is `1`, the value of `z` is `7` and the value of `t` is [`8, 9]`. You can also combine lists in a similar way ```liquidsoap x = [1, ...[2, 3, 4], 5, ...[6, 7]] ``` In this example, the value of `x` is `[1, 2, 3, 4, 5, 6 ,7]` ### Tuples Another construction present in Liquidsoap is _tuples_ of values, which are finite sequences of values which, contrarily to lists, might have different types. For instance, ``` (3, 4.2, "hello") ``` is a triple (a tuple with three elements) of type ``` int * float * string ``` which indicate that the first element is an integer, the second a float and the third a string. Similarly to lists, there is a special syntax in order to access tuple elements. For instance, if `t` is the above tuple `(3, 4.2, "hello")`, we can write ```liquidsoap let (n, x, s) = t ``` which will assign the first element to the variable `n`, the second element to the variable `x` and the third element to the variable `s`. ## Programming primitives ### Variables We have already seen many examples of uses of _variables_: we use ```liquidsoap x = e ``` in order to assign the result of evaluating an expression `e` to a variable `x`, which can later on be referred to as `x`. Variables can be masked: we can define two variables with the same name, and at any point in the program the last defined value for the variable is used: ```liquidsoap n = 3 print(n) n = n + 2 print(n) ``` will print `3` and `5`. Contrarily to most languages, the value for a variable cannot be changed (unless we explicitly require this by using references, see below), so the above program does not modify the value of `n`, it is simply that a new `n` is defined. There is an alternative syntax for declaring variables which is ```liquidsoap def x = e end ``` It has the advantage that the expression `e` can spread over multiple lines and thus consist of multiple expressions, in which case the value of the last one will be assigned to `x`. This is particularly useful to use local variables when defining a value. ### References As indicated above, by default, the value of a variable cannot be changed. However, one can use a _reference_ in order to be able to do this. Those can be seen as memory cells, containing values of a given fixed type, which can be modified during the execution of the program. They are created with the `ref` keyword, with the initial value of the cell as argument. For instance, ```liquidsoap r = ref(5) ``` declares that `r` is a reference which contains `5` as initial value. Since `5` is an integer (of type `int`), the type of the reference `r` will be ``` ref(int) ``` meaning that its a memory cell containing integers. On such a reference, two operations are available. - One can obtain the value of the reference by applying the reference to `()`, so that `r()` denotes the value contained in the reference `r`, for instance ```liquidsoap x = r() + 4 ``` declares the variable `x` as being 9 (which is 5+4). - One can change the value of the reference by using the `:=` keyword, e.g. ```liquidsoap r := 2 ``` will assign the value 2 to `r`. Internally, this is done by calling the `set` method of the reference, so that the above is equivalent to writing ```liquidsoap r.set(2) ``` which used to be the syntax for some reference manipulations. ### Loops The usual looping constructions are available in Liquidsoap. The `for` loop repeatedly executes a portion of code with an integer variable varying between two bounds, being increased by one each time. For instance, the following code will print the integers `1`, `2`, `3`, `4` and `5`, which are the values successively taken by the variable `i`: ```liquidsoap for i = 1 to 5 do print(i) end ``` In practice, such loops could be used to add a bunch of numbered files (e.g. `music1.mp3`, `music2.mp3`, `music3.mp3`, etc.) in a request queue for instance. The `while` loop repeatedly executes a portion of code, as long a condition is satisfied. For instance, the following code doubles the contents of the reference `n` as long as its value is below `10`: ```liquidsoap n = ref(1) while n() < 10 do n := n() * 2 end print(n()) ``` The variable `n` will thus successively take the values `1`, `2`, `4`, `8` and `16`, at which point the looping condition `n() < 10` is not satisfied anymore and the loop is exited. The printed value is thus `16`. ## Functions Liquidsoap is built around the notion of function: most operations are performed by those. For some reason, we sometimes call _operators_ the functions acting on sources. Liquidsoap includes a standard library which consists of functions defined in the Liquidsoap language, including fairly complex operators such as `playlist` which plays a playlist or `crossfade` which takes care of fading between songs. ### Basics A function is a construction which takes a bunch of arguments and produces a result. For instance, we can define a function `f` taking two float arguments, prints the first and returns the result of adding twice the first to the second: ```liquidsoap def f(x, y) print(x) 2*x+y end ``` This function can also be written on one line if we use semicolons (`;`) to separate the instructions instead of changing line: ```liquidsoap def f(x, y) = print(x); 2*x+y end ``` The type of this function is ``` (int, int) -> int ``` The arrow `->` means that it is a function, on the left are the types of the arguments (here, two arguments of type `int`) and on the right is the type of the returned value of the function (here, `int`). In order to use this function, we have to apply it to arguments, as in ``` f(3, 4) ``` This will trigger the evaluation of the function, where the argument `x` (resp. `y`) is replaced by `3` (resp. `4`), i.e., it will print `3` and return the evaluation of `2*3+4`, which is `10`. ### Anonymous functions For concision in scripts, it is possible define a function without giving it a name, using the syntax ```liquidsoap fun (x) -> ... ``` This is called an _anonymous function_, and it is typically used in order to specify short handlers in arguments. #### Anonymous function with no arguments You will see that it is quite common to use anonymous functions with no arguments. For this reason, we have introduced a special convenient syntax for those and allow writing ```liquidsoap {...} ``` instead of ```liquidsoap fun () -> ... ``` ### Labeled arguments A function can have an arbitrary number of arguments, and when there are many of them it becomes difficult to keep track of their order and their order matter! For instance, the following function computes the sample rate given a number of samples in a given period of time: ```liquidsoap def samplerate(samples, duration) = samples / duration end ``` which is of type ``` (float, float) -> float ``` For instance, if you have 110250 samples over 2.5 seconds the samplerate will be `samplerate(110250., 2.5)` which is 44100. However, if you mix the order of the arguments and type `samplerate(2.5, 110250.)`, you will get quite a different result and this will not be detected by the typing system because both arguments have the same type. Fortunately, we can give _labels_ to arguments in order to prevent this, which forces explicitly naming the arguments. This is indicated by prefixing the arguments with a tilde "`~`": ```liquidsoap def samplerate(~samples, ~duration) = samples / duration end ``` The labels will be indicated as follows in the type: ``` (samples : float, duration : float) -> float ``` Namely, in the above type, we read that the argument labeled `samples` is a float and similarly for the one labeled `duration`. For those arguments, we have to give the name of the argument when calling the function: ```liquidsoap samplerate(samples=110250., duration=2.5) ``` The nice byproduct is that the order of the arguments does not matter anymore, the following will give the same result: ```liquidsoap samplerate(duration=2.5, samples=110250.) ``` Of course, a function can have both labeled and non-labeled arguments. ### Optional arguments Another useful feature is that we can give _default values_ to arguments, which thus become _optional_: if, when calling the function, a value is not specified for such arguments, the default value will be used. For instance, if for some reason we tend to generally measure samples over a period of 2.5 seconds, we can make this become the value for the `duration` parameter: ```{.liquidsoap include="samplerate3.liq" from="BEGIN" to="END"} ``` In this way, if we do not specify a value for the duration, its value will implicitly be assumed to be 2.5, so that the expression: ```liquidsoap samplerate(samples=110250.) ``` will still evaluate to 44100. Of course, if we want to use another value for the duration, we can still specify it, in which case the default value will be ignored: ```liquidsoap samplerate(samples=132300., duration=3.) ``` The presence of an optional argument is indicated in the type by prefixing the corresponding label with "`?`", so that the type of the above function is ``` (samples : float, ?duration : float) -> float ``` ### Getters We often want to be able to dynamically modify some parameters in a script. For instance, consider the operator `amplify`, which takes a float and an audio source and returns the audio amplified by the given volume factor: we can expect its type to be ``` (float, source('a)) -> source('a) ``` so that we can use it to have a radio consisting of a microphone input amplified by a factor 1.2 by ```liquidsoap mic = input.alsa() radio = amplify(1.2, mic) ``` In the above example, the volume 1.2 was supposedly chosen because the sound delivered by the microphone is not loud enough, but this loudness can vary from time to time, depending on the speaker for instance, and we would like to be able to dynamically update it. The problem with the current operator is that the volume is of type `float` and a float cannot change over time: it has a fixed value. In order for the volume to have the possibility to vary over time, instead of having a `float` argument for `amplify`, we have decided to have instead an argument of type ``` () -> float ``` This is a function which takes no argument and returns a float (remember that a function can take an arbitrary number of arguments, which includes zero arguments). It is very close to a float excepting that each time it is called the returned value can change: we now have the possibility of having something like a float which varies over time. We like to call such a function a _float getter_, since it can be seen as some kind of object on which the only operation we can perform is get the value. For instance, we can define a float getter by ```liquidsoap n = ref(0.) def f () n := n() + 1. n() end ``` Each time we call `f`, by writing `f()` in our script, the resulting float will be increased by one compared to the previous one: if we try it in an interactive session, we obtain ``` # f();; - : float = 1.0 # f();; - : float = 2.0 # f();; - : float = 3.0 ``` Since defining such arguments often involves expressions of the form ```liquidsoap fun () -> e ``` which is somewhat heavy, we have introduced the alternative syntax ```liquidsoap {e} ``` for it. Finally, in order to simplify things a bit, you will see that the type of amplify is actually ``` ({float}, source('a)) -> source('a) ``` where the type `{float}` means that both `float` and `() -> float` are accepted, so that you can still write constant floats where float getters are expected. What we actually call a _getter_ is generally an element of such a type, which is either a constant or a function with no argument. In order to work with such types, the standard library often uses the following functions: - `getter`, of type `({'a}) -> {'a}`, creates a getter, - `getter.get`, of type `({'a}) -> 'a`, retrieves the current value of a getter, - `getter.function`, of type `({'a}) -> () -> 'a`, creates a function from a getter. ### Recursive functions Liquidsoap supports functions which are _recursive_, i.e., that can call themselves. For instance, in mathematics, the factorial function on natural numbers is defined as fact(n)=1×2×3×...×n, but it can also be defined recursively as the function such that fact(0)=1 and fact(n)=n×fact(n-1) when n>0: you can easily check by hand that the two functions agree on small values of n (and prove that they agree on all values of n). This last formulation has the advantage of immediately translating to the following implementation of factorial: ```liquidsoap def rec fact(n) = if n == 0 then 1 else n * fact(n-1) end end ``` for which you can check that `fact(5)` gives 120, the expected result. As another example, the `list.length` function, which computes the length of a list, can be programmed in the following way in Liquidsoap: ```liquidsoap def rec length(l) if l == [] then 0 else 1 + length(list.tl(l)) end end ``` We do not detail much further this trait since it is unlikely to be used for radios, but you can see a few occurrences of it in the standard library. ## Records and modules ### Records Suppose that we want to store and manipulate structured data. For instance, a list of songs together with their duration and tempo. One way to store each song is as a tuple of type `string * float * float`, but there is a risk of confusion between the duration and the length which are both floats, and the situation would of course be worse if there were more fields. In order to overcome this, one can use a _record_ which is basically the same as a tuple, excepting that fields are named. In our case, we can store a song as ```liquidsoap song = { filename = "song.mp3", duration = 257., bpm = 132. } ``` which is a record with three fields respectively named `filename`, `duration` and `bpm`. The type of such a record is ``` {filename : string, duration : float, bpm : float} ``` which indicates the fields and their respective type. In order to access a field of a record, we can use the syntax `record.field`. For instance, we can print the duration with ```liquidsoap print("The duration of the song is #{song.duration} seconds") ``` Records can be re-used using _spreads_: ```liquidsoap song = { filename = "song.mp3", duration = 257., bpm = 132. } # This is a fresh value with all the fields from `song` and # a new `id` field: song_with_id = { id = 1234, ...song } ``` Alternatively, you can also extend a record using the explicit `v.{...}` syntax: ```liquidsoap song = { filename = "song.mp3", duration = 257., bpm = 132. } # This is a fresh value with all the fields from `song` and # a new `id` field: song_with_id = song.{id = 1234} ``` ### Modules Records are heavily used in Liquidsoap in order to structure the functions of the standard library. We tend to call _module_ a record with only functions, but this is really the same as a record. For instance, all the functions related to lists are in the `list` module and functions such as `list.hd` are fields of this record. For this reason, the `def` construction allows adding fields in record. For instance, the definition ```liquidsoap def list.last(l) list.nth(l, list.length(l)-1) end ``` adds, in the module `list`, a new field named `last`, which is a function which computes the last element of a list. Another shorter syntax to perform definitions consists in using the `let` keyword which allows assigning a value to a field, so that the previous example can be rewritten as ```liquidasoap let list.last = fun(l) -> list.nth(l, list.length(l)-1) ``` If you often use the functions of a specific module, the `open` keyword allows using its fields without having to prefix them by the module name. For instance, in the following example ```liquidsoap l = [1,2,3] open list x = nth(l, length(l)-1) ``` the `open list` directive allows directly using the functions in this module: we can simply write `nth` and `length` instead of `list.nth` and `list.length`. ### Values with fields A unique feature of the Liquidsoap language is that it allows adding fields to any value. We also call them _methods_ by analogy with object-oriented programming. For instance, we can write ```liquidsoap song = "test.mp3".{duration = 123., bpm = 120.} ``` which defines a string (`"test.mp3"`) with two methods (`duration` and `bpm`). This value has type ``` string.{duration : float, bpm : float} ``` and behaves like a string, e.g. we can concatenate it with other strings: ```liquidsoap print("the song is " ^ song) ``` but we can also invoke its methods like a record or a module: ```liquidsoap print("the duration is #{song.duration}") ``` The construction `def replaces` allows changing the main value while keeping the methods unchanged, so that ```liquidsoap def replaces song = "newfile.mp3" end print(song) ``` will print ``` "newfile.mp3".{duration = 123., bpm = 120.} ``` (note that the string is modified but not the fields `duration` and `bpm`). ### Optional fields During the execution of your script, it can be useful to allow functions to receive records that may or may not have a specific field. This can be used, for instance, to model optional arguments. This can be achieved in two ways: 1. Using the `x.foo ?? default` syntax Here's an example: ```liquidsoap # This functions adds 1 to x unless options has a # add field in which case it adds this value def f(x, options) = x + (options.add ?? 1) end ``` The type of this function is: ```liquidsoap f : (int, 'a.{add? : int}) -> int = <fun> ``` which denotes that the `options` argument can be any value that may or may not have a `add` field. However, if this field is present, it must be of type `int`. 2. Using the `x?.foo` syntax Given a variable `x`, `x?.foo` returns the field value `foo`, if present, or `null` otherwise. The `?.` syntax can be chained and works with functions, which make it a very convenient way to drill deep inside nested records: ```liquidsoap x?.fn(123, "aabb")?.field ``` ## Patterns As explained earlier, you can use several constructions to extract data from structured values such as `let [x, y] = l` and etc. These constructions are called _patterns_. Patterns allows to quickly access values nested deeply inside structured data in a way that remains pretty intuitive when reading the code. Patterns are constructed using _variable placeholders_, which are either a variable name such as: `x`, `foo`, etc. or the special symbol `_` for any ignored value. ### Tuple patterns Tuple patterns are pretty straight forward and consist of any sequence of variable captures: ```liquidsoap let (x, y, _, z) = (123, "aabbcc", true, 3.14) # x = 1, y = "aabbcc", z = 3.14 ``` ### List patterns List patterns are composed of variable placeholders, etc. and spreads of the form: `...<variable placeholder>` such as: `...z`. The spread `..._` can be simply written `...`. See below for an example. You can use any combination of: - Forward variable names: these capture the first elements of the list. - One spread: this captures any remaining element as a list. - Backward variable names: these capture the last elements of a the list. Here are some examples: ```liquidsoap # Forward capture: let [x, y, z] = [1, 2, 3] # x = 1, y = 2, z = 3 # Forward capture with spread: let [x, y, ...z] = [1, 2, 3, 4] # x = 1, y = 2, z = [3, 4] # Forward capture with ignored values: let [_, x, ...z] = [1, 2, 3, 4] # x = 2, z = [3, 4] # Full capture: let [x, y, ...z, t, u, v] = [1, 2, 3, 4, 5, 6, 7, 8, 9] # x = 1, y = 2, z = [3, 4, 5, 6, 7], t = 7, u = 8, v = 9 # Backward capture only. let [..., t, u, v] = [1, 2, 3, 4, 5] # t = 3, u = 4, v = 5 ``` ### Record and module patterns Record and module patterns consist of either variable names (not variable capture!), which capture method values or variable names with an associated pattern. Record patterns are of the form: `{<captured methods>}` while module patterns are of the form: `<variable capture>.{<captured methods>}` Here are some examples: ```liquidsoap # Record capture let {foo, bar} = {foo = 123, bar = "baz", gni = true} # foo = 123, bar = "baz" # Record capture with spread let {foo, bar, ...x} = {foo = 123, bar = "baz", gni = true} # foo = 123, bar = "baz", x = {gni = true} # Module capture let v.{foo, bar} = "aabbcc".{foo = 123, bar = "baz", gni = true} # v = "aabbcc", foo = 123, bar = "baz" # Module capture with ignored value let _.{foo, bar} = "aabbcc".{foo = 123, bar = "baz", gni = true} # foo = 123, bar = "baz" # Record capture with sub-patterns. Same works for module! let {foo = [x, y, z], gni} = {foo = [1, 2, 3], gni = "baz"} # foo = [1, 2, 3], x = 1, y = 2, z = 3, gni = "baz" # Record capture with optional methods: let { foo? } = () # foo = null() let { foo? } = { foo = 123 } # foo = 123 ``` ## Combining patterns As seen with record and modules, patterns can be combined at will, for instance, these are all valid patterns: ```liquidsoap let [{foo}, {gni}, ..., {baz}] = l let (_.{ bla = [..., z] }, t, _, u) = x ``` ## Advanced values In this section, we detail some more advanced values than the ones presented in. You are not expected to be understanding those in details for basic uses of Liquidsoap. ### Errors In the case where a function does not have a sensible result to return, it can raise an _error_. Typically, if we try to take the head of the empty list without specifying a default value (with the optional parameter `default`), an error will be raised. By default, this error will stop the script, which is usually not a desirable behavior. For instance, if you try to run a script containing ```liquidsoap list.hd([]) ``` the program will exit printing ``` Error 14: Uncaught runtime error: type: not_found, message: "no default value for list.hd" ``` This means that the error named "`not_found`" was raised, with a message explaining that the function did not have a reasonable default value of the head to provide. In order to avoid this, one can _catch_ exceptions with the syntax ```liquidsoap try code catch err do handler end ``` This will execute the instructions `code`: if an error is raised at some point during this, the code `handler` is executed, with `err` being the error. For instance, instead of writing ```liquidsaop l = [] x = list.hd(default=0, l) ``` we could equivalently write ```liquidsoap l = [] x = try list.hd(l) catch err do 0 end ``` The name and message associated to an error can respectively be retrieved using the error `kind` and `message` attributes, e.g. we can write ```liquidsoap try ... catch err do print("the error #{err.kind} was raised") print("the error message is #{err.message}") end ``` Typically, when reading from or writing to a file, errors will be raised when a problem occurs (such as reading from a non-existent file or writing a file in a non-existent directory) and one should always check for those and log the corresponding message: ```liquidsoap data = "bla" try file.write(data=data, "/non/existent/path") catch err do log.important("Could not write to file: #{error.message(err)}") end ``` Specific errors can be caught with the syntax ```liquidsoap try ... catch err : l do ... end ``` where `l` is a list of error names that we want to handle here. Errors can be raised from Liquidsoap with the function `error.raise`, which takes as arguments the error to raise and the error message. For instance: ```liquidsoap error.raise(error.not_found, "we could not find your result") ``` We should also mention that all the errors should be declared in advance with the function `error.register`, which takes as argument the name of the new error to register: ```liquidsoap myerr = error.register("my_error") error.raise(myerr, "testing my own error") ``` Lastly, if you need to make sure that a certain piece of code is executed whether or not there is an exception raised, you can use _finally_: ```liquidsoap # Without a catch block try ... finally ... end # With a catch block try ... catch ... do ... finally ... end ``` This is roughly equivalent to: ```liquidsoap finally_called = ref(false) def finally() = ... end try let ret = ... finally_called := true finally() ret # If specified: catch ... do let ret = ... if not finally_called() then finally() end ret end ``` The biggest different is that `finally` is called on all errors, including internal errors that cannot be caught by the runtime code. Errors raised in a `finally` block do override any previously raised errors. ### Nullable values It is sometimes useful to have a default value for a type. In Liquidsoap, there is a special value for this, which is called `null`. Given a type `t`, we write `t?` for the type of values which can be either of type `t` or be `null`: such a value is said to be _nullable_. For instance, we could redefine the `list.hd` function in order to return null (instead of raising an error) when the list is empty: ```liquidsoap def list.hd(l) if l == [] then null() else list.hd(l) end end ``` whose type would be ``` (['a]) -> 'a? ``` since it takes as argument a list whose elements are of type `'a` and returns a list whose elements are `'a` or `null`. As it can be observed above, the null value is created with `null()`. In order to use a nullable value, one typically uses the construction `x ?? d` which is the value `x` excepting when it is null, in which case it is the default value `d`. For instance, with the above head function: ```liquidsoap x = list.hd(l) print("the head is " ^ (x ?? "not defined")) ``` Some other useful functions include - `null.defined`: test whether a value is null or not, - `null.get`: obtain the value of a nullable value supposed to be distinct from `null`, - `null.case`: execute a function or another, depending on whether a value is null or not. ### Runtime evaluation of scripting values Similarly to how JSON is [parsed](json.html), you can evaluate string into values at runtime using the `eval` decorator. As with JSON, too, the recommended way to use it is by adding an explicit type annotation: ```liquidsoap let eval (x: {foo: int, bla: string}) = "{foo = 123, bla = \"gni\"}" print("x.foo = #{x.foo}, x.bla = #{x.bla}") ``` ### Including other files It is often useful to split your script over multiple files, either because it has become quite large, or because you want to be able to reuse common functions between different scripts. You can include a file `file.liq` in a script by writing ```liquidsoap %include "file.liq" ``` which will be evaluated as if you had pasted the contents of the file in place of the command. For instance, this is useful in order to store passwords out of the main file, in order to avoid risking leaking those when handing the script to some other people. Typically, one would have a file `passwords.liq` defining the passwords in variables, e.g. ```liquidsoap radio_pass = "secretpassword" ``` and would then use it by including it: ```liquidsoap %include "passwords.liq" radio = ... output.icecast(%mp3, host="localhost", port=8000, password=radio_pass, mount="my-radio.mp3", radio) ``` so that passwords are not shown in the main script. ### Code comments Comments can be added to your code in two ways: _Multi-line comments_ are comments that can span multiple lines. They are delimitated by the sequence of characters `#<` at the beginning and `>#` at the end. Anything in between those two sequences is considered code comment. Here are some examples: Simple multiline comments: ```liquidsoap #< This is a comment ># ``` Multiline comments can be nested: ```liquidsoap #< This is a top-level comment # This is also a comment #< This is a nested code comment ># ># ``` Fancy looking multiline comment ```liquidsoap #<------- BEGIN CODE COMMENT ----# Comments can also look like this #--------- END CODE COMMENT -----># ``` _Single-line comments_ are comments that are limited to the current line. Such comments are started with the character `#` without a following `<`. Anything after the initial `#` character and until the end of the line is considered code comment: ```liquidsoap def f(x) = # This is a single line comment. 123 end ``` ## Caching Type-checking scripts can take a lot of time and consume memory. To optimize things, this step can be cached. During the first execution, the script is parsed, type checked and evaluated. On second and any following execution, a cache of the script is used, reducing the typechecking phase, sometimes by a `100x` factor! Here's a log without caching on a M3 macbook pro: ``` 2024/07/03 14:31:41 [startup:3] main script hash computation: 0.03s 2024/07/03 14:31:41 [startup:3] main script cache retrieval: 0.03s 2024/07/03 14:31:41 [startup:3] stdlib hash computation: 0.03s 2024/07/03 14:31:41 [startup:3] stdlib cache retrieval: 0.03s 2024/07/03 14:31:41 [startup:3] Typechecking stdlib: 3.37s 2024/07/03 14:31:41 [startup:3] Typechecking main script: 0.00s ``` And the same log after caching: ``` 2024/07/03 14:32:59 [startup:3] main script hash computation: 0.02s 2024/07/03 14:32:59 [startup:3] Loading main script from cache! 2024/07/03 14:32:59 [startup:3] main script cache retrieval: 0.05s ``` Scripts can be cached ahead of time without executing them, for instance while compiling a docker image, using `--cache-only`. Caching can also be disabled using `--no-cache`. Caching happens at two different time: - First the standard library is cached - Then the script itself is cached Caching the standard library makes it possible to run the type-checker faster on new scripts. Here's an example of a log from running a new script with a cached standard library: ``` 2024/07/03 14:33:27 [startup:3] main script hash computation: 0.02s 2024/07/03 14:33:27 [startup:3] main script cache retrieval: 0.02s 2024/07/03 14:33:27 [startup:3] stdlib hash computation: 0.03s 2024/07/03 14:33:27 [startup:3] Loading stdlib from cache! 2024/07/03 14:33:27 [startup:3] stdlib cache retrieval: 0.10s 2024/07/03 14:33:27 [startup:3] Typechecking main script: 0.00s ``` Caching can be disabled by setting `LIQ_CACHE` to anything else than `"true"`. ### Cache locations Cache files can accumulate and also take up disk space so it is important to know where they are located! There are two type of cache locations: - System cache for cached files that should be shared with all liquidsoap scripts. This is where the standard library cache is located. This location is a system-wide path on unix system such as `/var/cache/liquidsoap`. - User cache for cached files that are specific to the user running liquidsoap scripts. On unix systems, this location is at `$HOME/.cache/liquidsoap`. On windows, the default cache directory for both type of cache locations is in the same directory as the binary. At runtime, `liquidsoap.cache(mode=<mode>)` returns the cache directory. `mode` should be one of: `"user"` or `"system"`. ### Cache maintenance There is a cache maintenance routine which deletes unused cache files after `10` days and keeps the cache to a maximum of `200` files. You can run the cache maintenance routing by calling `liquidsoap.cache.maintenance(mode=<mode>)` manually. Here, too, `mode` should be one of: `"user"` or `"system"`. ### Cache security Please be aware that the cache does _not_ encrypt its values. As such, user cache files should be considered sensitive as they may contain password and other runtime secrets that are available through your scripts. We recommend to: - Use environment variables as much as possible when passing secrets - Secure your user script and cache files. The default creation permissions for user cache files is: `0o600` so only the user creating them should be able to read them. You should make sure that your script permissions are also similarly restricted. ### Cache and memory usage One side-benefit from loading a script from cache is that the entire typechecking process is skipped. This can result is significant reduction in the initial memory consumption, typically down from about `375MB` to about `80MB`! If memory consumption is a concern but you are not sure you can cache your script, you can also set the environment variable `settings.init.compact_before_start` to `true`: ```liquidsoap settings.init.compact_before_start := true ``` This will run the OCaml memory compaction algorithm after typechecking your script but before running it. This will result in a similar memory footprint when running the script but will delay its initial startup time. ### Cache environment variables The following environment variables control the cache behavior: - `LIQ_CACHE`: disable the cache when set to anything else than `1` or `true` - `LIQ_CACHE_SYSTEM_DIR`: set the cache system directory - `LIQ_CACHE_SYSTEM_DIR_PERMS`: set the permission used when creating cache system directory (and its parents when needed). Default: `0o755` - `LIQ_CACHE_SYSTEM_FILE_PERMS`: set the permissions used when creating a system cache file. Default: `0o644` - `LIQ_CACHE_USER_DIR`: set the cache user directory - `LIQ_CACHE_USER_DIR_PERMS`: set the permission used when creating cache user directory (and its parents when needed). Default: `0o700`. - `LIQ_CACHE_USER_FILE_PERMS`: set the permissions used when creating a user cache file. Default: `0o600` - `LIQ_CACHE_MAX_DAYS`: set the maximum days a cache file can be stored before it is eligible to be deleted during the next cache maintenance pass. - `LIQ_CACHE_MAX_FILES`: set the maximum number of files in each cache directory. Older files are removed first. �������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/liq/�������������������������������������������������������������������0000775�0000000�0000000�00000000000�14773033502�0016700�5����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/liq/Makefile�����������������������������������������������������������0000664�0000000�0000000�00000000166�14773033502�0020343�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������all: check: @for i in *.liq; do \ echo -n "Testing $$i...

This is not an easy topic as there are several layers of memory management inside the application and also some trade-off considerations between memory footprint and CPU usage. As of writing (version `2.2.0`), some of the trade-off that we are making with the OCaml garbage collector do not seem satisfactory in some memory-intensive conditions. Hopefully, this will improve in future major release (`2.3.x` and later). But first, let's look at what's going on. ### The OCaml memory model The OCaml compiler provides a garbage collector. This module is able to track memory blocks used by the OCaml program and free them when they are not used without the programmer's intervention. This is done by scanning the memory currently allocated by the OCaml program to identify the memory blocks that are not in use anymore. While this is transparent to the user (you!), this also means that there will be extra CPU cycles dedicated to this operation. How often these cycle occur help controlling the growth of unused memory but with the understanding that _to minimize unused memory, more CPU cycles have to be dedicated to tracking it_. You can find more information about the OCaml garbage collection on [this page](https://ocaml.org/docs/garbage-collection). Inside liquidsoap scripts, the operations that the OCaml compiler provides to control the garbage collector are available within the `runtime.gc` module. The documentation for these operations can be found in the [OCaml Gc module documentation](https://v2.ocaml.org/api/Gc.html). Typically, to change the garbage collector parameters, one can do: ```{.liquidsoap include="space_overhead.liq" from=1} ``` These parameters and functions make it possible to experiment and see if you can find better parameters for your application. ### C memory allocations Not all the memory in the application is allocated by the OCaml garbage collector. External libraries such as `ffmpeg`, `libmp3lame` and etc. need to allocate their own memory. This is usually referred to as _C memory allocations_ though it does not have to be allocated by a program written in `C`.. Another, more technically appropriate is _heap memory_ though, dynamically memory allocated by the OCaml garbage collector also lives in the program's heap.. 😅 This type of memory is also cleaned up by the OCaml garbage collector. To do so, a _custom block_ is passed to the OCaml program with a reference to a C memory pointer and how to clean it up. When the OCaml program detects that this custom block is no longer in use, it triggers the required operations to clean its corresponding C memory. However, things get complicated when considering how to fine-tune the garbage collector to account for memory allocated on the C side.. Remember that, as we discussed in the previous section, the garbage collector has to consume CPU cycles to free up memory. And, in the case of memory allocated on the C side, a single OCaml value (usually a small amount of memory) can actually refer to a much larger amount of C memory. This is typically the case when the corresponding C memory represents decoded video frames, which is usually a fairly large amount of memory. In general, the trade-off is: if the garbage collector does not run often enough, a lot of these rather larger C memory blocks are lingering longer, which leads to potentially huge amount of memory needlessly consumed by the application. Conversely, if the garbage collector runs too often, memory usage is controlled but CPU usage is increased. As of now, the strategy implemented by the OCaml compiler consists in tracking the ratio of OCaml held memory vs. its corresponding C memory and running the garbage collector more often when this ratio increases. However, this is not optimal in cases where the application purposefully holds large amount of C memory such as when doing video processing. In the future, we would like to explore tightening up our control of this mechanism. It should be possible trick the garbage collector by not declaring the full anmount of allocated C memory to make it possible to run the memory cleaning operations on purpose and at specific times, typically after a streaming cycle has ended. Most of the tools for that are already exported in the scripting language so, we will make sure to report our progress on the [blog](https://liquidsoap.info/blog) for anyone to test it. ### Audio data format Another source of memory usage is the audio data format. By default, we store audio data using OCaml's native floating point numbers in order to be able to run the application, including audio processing (crossfade, filters, fades etc) at the best possible speed and CPU usage. However, OCaml's native float are stored using 64 bits (8 bytes), which is a large amount of memory per number. If you are concerned with reducing your audio memory footprint, for instance if your applications has a lot of audio sources with buffers, you can do a couple of things: 1. Use the [ffmpeg raw content](ffmpeg.html). This means storing all the audio content as ffmpeg audio frames. This is an opaque format that works very well if your script can use ffmpeg end-to-end, for instance processing audio using [ffmpeg filters](ffmpeg_filters.html).. 2. Use one of the `pcm_f32` or `pcm_s16` audio format. These formats are less opaque. Their data is stored in a C memory array and can be accessed by the OCaml program. Some, but not all, of our operators do support them transparently. When using `pcm_s16`, audio samples are stored as 16 bit signed integers (2 bytes, the audio CD format). When using `pcm_f32`, audio samples are stored as 32 bit float (4 bytes). 16 bit signed integers is probably enough for most applications and consumes 4 times less memory than OCaml's native floating point numbers. The `pcm_*` formats can be required by the encoders by adding `pcm_s16` or `pcm_f32` to their list of parameters. This will, in turn, inform all operators and decoders to operate with this format, if they support it: ```liquidsoap # Mp3 encoder, pcm_s16 encoder = %mp3(pcm_s16, channels=2) # Ogg/opus encoder, pcm_f32 encoder = %ogg(%vorbis(pcm_f32)) # FFmpeg AAC encoder, pcm_s16 encoder = %ffmpeg(format="mp4",%audio(pcm_s16, codec="aac")) ``` For both `pcm_*` and ffmpeg raw formats, you can use also conversion functions (`ffmpeg.raw.decode.*`, `ffmpeg.raw.encode.*`, `audio.decode.pcm_*`, `audio.encode.pcm_*`) to convert content back and forth. In general, working with the `pcm_*` formats is easier. If you know what you are doing, though, working with raw FFmpeg frames can also have some advantages. In both cases, there might be an increase in CPU usage if your script needs to process audio (for instance via a `crossfade`) when converting these formats back and forth. Finally, if you need to store large amount of audio data, for instance to create a one hour delay, you should consider using the `track.audio.defer` operator which was designed for this purpose. ### `jemalloc` Lastly, the user-land memory allocator [jemalloc](https://github.com/jemalloc/jemalloc) can be used to control all memory allocations (C and OCaml). This allocator is particularly good at preventing memory fragmentation, which is an important topic for an application like liquidsoap running short streaming cycle involving small amount of memory (FFmpeg frames etc). The allocator is enabled by installing the `jemalloc` opam package and is included in all our production builds (except windows). It also comes with a lot of customization options that are exported via the [runtime.jemalloc.\*](https://www.liquidsoap.info/doc-dev/reference.html#runtime.jemalloc.epoch) functions. If you want to explore more, we recommend [reading about it](https://engineering.fb.com/2011/01/03/core-data/scalable-memory-allocation-using-jemalloc/) and then exploring the [manual page](http://jemalloc.net/jemalloc.3.html) which contains details about all the available settings. �������������������������������liquidsoap-2.3.2/doc/content/metadata.md������������������������������������������������������������0000664�0000000�0000000�00000007172�14773033502�0020224�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Customize metadata using Liquidsoap Liquidsoap has several mechanism for manipulating the metadata attached to your stream. In this page we quickly detail and compare the different operators, see the [language reference](reference.html) for full details about them. **Warning**. The protocol used by Shoutcast and Icecast before version 2 does not support many fields. It mainly support one: `song`. So, if you need to customize the metadata displayed by these servers, you should customize only the `song` metadata. ## The annotate protocol The metadata are read from files, so the most simple way is to properly tag the files. However, if it not possible to modify the files for some reason, the `annotate` protocol can be used in playlists to insert and modify some metadata. For instance, in the playlist ``` annotate:title="Title 1",artist="Artist 1":music1.mp3 annotate:title="Title 2",artist="Artist 2":music2.mp3 ``` the title metadata for file music1.mp3 will be overridden and changed to ``Title 1'' (and similarly for the artist). ## Map metadata The `metadata.map` operator applies a specified function to transform each metadata chunk of a stream. It can be used to add or decorate metadata, but is also useful in more complex cases. A simple example using it: ```liquidsoap # A function applied to each metadata chunk def append_title(m) = # Grab the current title title = m["title"] # Return a new title metadata [("title","#{title} - www.station.com")] end # Apply metadata.map to s using append_title s = metadata.map(append_title, s) ``` The effect of `metadata.map` by default is to update the metadata with the returned values. Hence in the function `append_title` defined in the code above returns a new metadata for the label `title` and the other metadata remain untouched. You can change this by using the `update` option, and you can also remove any metadata (even empty one) using the `strip` option. See the documentation on `metadata.map` for more details. ## Insert metadata ### Using the telnet server This operator is used for inserting metadata using a server command. If you have an `server.insert_metadata` node named `ID` in your configuration, as in ``` server.insert_metadata(id="ID", source) ``` you can connect to the server (either telnet or socket) and execute commands like ``` ID.insert key1="val1",key2="val2",... ``` ### In Liquidsoap Sometimes it is desirable to change the metadata dynamically when an event occurs. In this case, the function `insert_metadata` (not to be confused with `server.insert_metadata` above) can be used: when applied to a source it returns a source with an added `insert_metadata` method. For instance, suppose that you want to insert metadata on the stream using the OSC protocol. When a pair of strings `title'' `The new title'' is received on `/metadata`, we want to change the title of the stream accordingly. This can be achieved as follows. ```liquidsoap # Our main music source s = playlist("...") s = mksafe(s) # Create a source with a `insert_metadata` method s = insert_metadata(s) # Handler for OSC events (gets pairs of strings) def on_meta(m) = # Extract the label label = fst(m) # Extract the value value = snd(m) # A debug message print("Insert metadata #{label} = #{value}") # Insert the metadata s.insert_metadata([(label,value)]) end # Call the above handler when we have a pair of strings on /metadata osc.on_string_pair("/metadata",on_meta) # Output on icecast output.icecast(%mp3,mount="test.mp3",s) ``` We can then change the title of the stream by sending OSC messages, for instance ``` oscsend localhost 7777 "/metadata" ss "title" "The new title" ``` ������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/migrating.md�����������������������������������������������������������0000664�0000000�0000000�00000063410�14773033502�0020422�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Migrating to a new Liquidsoap version In this page, we list the most common catches when migrating to a new version of Liquidsoap. ### Generalities If you are installing via `opam`, it can be useful to create a [new switch](https://opam.ocaml.org/doc/Usage.html) to install the new version of `liquidsoap`. This will allow to test the new version while keeping the old version around in case you to revert to it. More generally, we recommend to always keep a version of your script around and also to make sure that you test your new script with a staging environment that is close to production. Streaming issues can build up over time. We do our best to release the most stable possible code but problems can arise from many reasons so, always best to first to a trial run before putting things to production! ## From 2.2.x to 2.3.x ### Script caching A mechanism for caching script was added. There are two caches, one for the standard library that is shared by all scripts, and one for individual scripts. Scripts should run the same way with or without caching. However, caching your script has two advantage: - The script starts much faster. - Much less memory is used when starting. This memory is used the first time running the script to typecheck it and more. This is what we're caching. You can pre-cache a script using the `--cache-only` command: ```liquidsoap $ liquidsoap --cache-only /path/to/script.liq ``` The location of the two caches can be found by running `liquidsoap --build-config`. You can also set them using the `$LIQ_CACHE_USER_DIR` and `$LIQ_CACHE_SYSTEM_DIR` environment variables. Typically, inside a docker container, to pre-cache a script you would set `$LIQ_CACHE_SYSTEM_DIR` to the appropriate location and then run `liquidsoap --cache-only`: ```dockerfile ENV LIQ_CACHE_USER_DIR=/path/to/liquidsoap/cache RUN mkdir -p $LIQ_CACHE_USER_DIR && \ liquidsoap --cache-only /path/to/script.liq ``` See [the language page](language.html#caching) for more details! ### Default frame size Default frame size has been set to `0.02s`, down from `0.04s` in previous releases. This should lower the latency of your liquidsoap script. See [this PR](https://github.com/savonet/liquidsoap/pull/4033) for more details. ### Crossfade transitions and track marks Track marks can now be properly passed through crossfade transitions. This means that you also have to make sure that your transition function is fallible! For instance, this silly transition function: ```liquidsoap def transition(_, _) = blank(duration=2.) end ``` Will never terminate! Typically, to insert a jingle you would do: ```liquidsoap def transition(old, new) = sequence([old.source, single("/path/to/jingle.mp3"), new.source]) end ``` ### Replaygain - There is a new `metadata.replaygain` function that extracts the replay gain value in _dB_ from the metadata. It handles both `r128_track_gain` and `replaygain_track_gain` internally and returns a single unified gain value. - The `file.replaygain` function now takes a new compute parameter: `file.replaygain(~id=null(), ~compute=true, ~ratio=50., file_name)`. The compute parameter determines if gain should be calculated when the metadata does not already contain replaygain tags. - The `enable_replaygain_metadata` function now accepts a compute parameter to control replaygain calculation. - The `replaygain` function no longer takes an `ebu_r128` parameter. The signature is now simply: `replaygain(~id=null(), s)`. Previously, `ebu_r128` allowed controlling whether EBU R128 or standard replaygain was used. However, EBU R128 data is now extracted directly from metadata when available. So `replaygain` cannot control the gain type via this parameter anymore. ### Regular expressions The library providing regular expressions has been switched with `2.3.0`. This means that subtle differences can arise with the evaluation of some regular expressions. Here's an example that was recently reported: In `2.2.x`, this was true: ``` # When using a regular expression with a capture pattern to split, the value matched for splitting is returned: % string.split(separator="(:|,)", "foo:bar") ["foo", ":", "bar"] # But not when using a regular expression without matching: % string.split(separator=":|,", "foo:bar") ["foo", "bar"] ``` In `2.3.x`, the matched pattern is not returned: ``` % string.split(separator="(:|,)", "foo:bar") ["foo", "bar"] % string.split(separator=":|,", "foo:bar") ["foo", "bar"] ``` ### Static requests Static requests detection can now work with nested requests. Typically, a request for this URI: `annotate:key="value",...:/path/to/file.mp3` will be considered static if `/path/to/file.mp3` can be decoded. Practically, this means that more source will now be considered infallible, for instance a `single` using the above uri. In most cases, this should improve the user experience when building new scripts and streaming systems. In rare cases where you actually wanted a fallible source, you can still pass `fallible=true` to e.g. the `single` operator or use the `fallible:` protocol. ### String functions Some string functions have been updated to account for string encoding. In particular, `string.length` and `string.sub` now assume that their given string is in `utf8` by default. While this is what most user expect, this can lead to backward incompatibilities and new exceptions. You can change back to the old default by passing `encoding="ascii"` to these functions or using the `settings.string.default_encoding` settings. ### `check_next` `check_next` in playlist operators is now called _before_ the request is resolved, to make it possible to cut out unwanted requests before consuming process time. If you need to see the request's metadata or if the request resolves into a valid tile, however, you might need to call `request.resolve` inside your `check_next` script. ### Regular expressions The backend to interpret regular expressions has been changed. For the most part, all existing regular expressions should be supported but you might experience some incompatibilities with advanced/complex ones. Known incompatibilities include: - `(?P<name>pattern)` for named captures is not supported. `(?<name>pattern)` should be used instead. ### `segment_name` in HLS outputs To make segment name more flexible, `duration` (segment duration in seconds) and `ticks` (segment exact duration in liquidsoap's main ticks) have been added to the data available when calling `segment_name`. To prevent any further breakage of this function, its arguments have been changed to a single record containing all the available attributes: ```liquidsoap def segment_name(metadata) = "#{metadata.stream_name}_#{metadata.position}.#{metadata.extname}" end ``` ### `on_air` metadata Request `on_air` and `on_air_timestamp` metadata are deprecated. These values were never reliable. They are set at the request level when `request.dynamic` and all its derived sources start playing a request. However, a request can be used in multiple sources and the source using it can be used in multiple outputs or even not be actually being on the air if, for instance, it not selected by a `switch` or `fallback`. Instead, it is recommended to get this data directly from the outputs. Starting with `2.3.0`, all output now add `on_air` and `on_air_timestamp` to the metadata returned by `on_track`, `on_metadata` and `last_metadata` and the telnet `metadata` command. For the telnet `metadata` command, these metadata need to be added to the `settings.encoder.metadata.export` setting first. If you are looking for an event-based API, you can use the output's `on_track` methods to track the metadata currently being played and the time at which it started being played. For backward compatibility and easier migration, `on_air` and `on_air_timestamp` metadata can be enabled using the `settings.request.deprecated_on_air_metadata` setting: ```liquidsoap settings.request.deprecated_on_air_metadata := true ``` However, it is highly recommended to migrate your script to use one of the new method. ### `last_metadata` The implementation of `last_metadata` was updated to clear the last metadata when a new track begins. This is more in line with most user's expectation: last metadata is intended to reflect the metadata of the current track. If you need to, you can revert to the previous behavior using the source's `reset_last_metadata_on_track` method: ```liquidsoap s.reset_last_metadata_on_track := false ``` ### Gstreamer `gstreamer` was removed. It had been deprecated for a while. We expect `ffmpeg` to carry most, if not all of gstreamer's features. See [this PR](https://github.com/savonet/liquidsoap/pull/4036) for more details. ### Prometheus The default port for the Prometheus metrics exporter has changed from `9090` to `9599`. As before, you can change it with `settings.prometheus.server.port := <your port value>`. ### `source.dynamic` Many operators such as `single` and `request.once` have been reworked to use `source.dynamic` as their underlying implementation. The operator is now considered usable in production although we urge caution when using it: it is very powerful but can also break things! If you were (boldly!) using this operator before, the most important change is that its `set` method has been removed in favor of a unique callback API. ## From 2.1.x to 2.2.x ### References The `!x` notation for getting the value of a reference is now deprecated. You should write `x()` instead. And `x := v` is now an alias for `x.set(v)` (both can be used interchangeably). ### Icecast and Shoutcast outputs `output.icecast` and `output.shoutcast` are some of our oldest operators and were in dire need of some cleanup so we did it! We applied the following changes: - You should now use `output.icecast` only for sending to icecast servers and `output.shoutcast` only for sending to shoutcast servers. All shared options have been moved to their respective specialized operator. - Old `icy_metadata` argument was renamed to `send_icy_metadata` and changed to a nullable `bool`. `null` means guess. - New `icy_metadata` argument now returns a list of metadata to send with ICY updates. - Added a `icy_song` argument to generate default `"song"` metadata for ICY updates. Defaults to `<artist> - <title>` when available, otherwise `artist` or `title` if available, otherwise `null`, meaning don't add the metadata. - Cleaned up and removed parameters that were irrelevant to each operator, i.e. `icy_id` in `output.icecast` and etc. - Made `mount` mandatory and `name` nullable. Use `mount` as `name` when `name` is `null`. ### HLS events Starting with version `2.2.1`, on HLS outputs, `on_file_change` events are now `"created"`, `"updated"` and `"deleted"`. This breaking was required to reflect the fact that file changes are now atomic. See [this issue](https://github.com/savonet/liquidsoap/issues/3284) for more details. ### `cue_cut` Starting with version `2.2.4`, the `cue_cut` operator has been removed. Requests cue-in and cue-out processing has been integrated directly into requests resolution. In most cases, you simply can remove the operator from your script. In some cases, you might need to disable `cue_in_metadata` and `cue_out_metadat` either when creating new requests or when creating `playlist` sources. ### Harbor HTTP server and SSL support The API for registering HTTP server endpoint and using SSL was completely rewritten. It should be more flexible and provide node/express like API for registering endpoints and middleware. You can checkout [the harbor HTTP documentation](harbor_http.html) for more details. The [Https support](harbor_http.html#https-support) section also explains the new SSL/TLS API. ### Timeout We used to have timeout values labelled `timeout` or `timeout_ms`, some of these would be integer and in milliseconds, other floating point and in seconds etc. This was pretty confusing so, now all `timeout` settings and arguments have been unified to be named `timeout` and hold a floating point value representing a number of seconds. In most cases, your script will not execute until you have updated your custom `timeout` values but you should also review all of them to make sure that they follow the new convention. ### Metadata overrides Some metadata overrides have been made to reset on track boundaries. Previously, those were permanent even though they were documented as only applying to the current track. If you need to keep the previous behavior, you can used the `persist_overrides` parameters (`persis_override` for `cross`/`crossfade`). The list of concerned metadata is: - `"liq_fade_out"` - `"liq_fade_skip"` - `"liq_fade_in"` - `"liq_cross_duration"` - `"liq_fade_type"` ### JSON rendering The confusing `let json.stringify` syntax has been removed as it did not provide any feature not already covered by either the `json.stringify()` function or the generic `json()` object mapper. Please use either of those now. ### Default character encoding in `output.{harbor,icecast,shoutcast}` Default encoding for `output.harbor`, `output.icecast` and `output.shoutcast` metadata has been changed to `UTF-8` in all cases. Legacy systems used to expect `ISO-8859-1` (also known as `latin1`) for metadata inserted into `mp3` streams via the `icy` mechanism. It seems that, nowadays, most software expect `UTF-8` out of the box, including for legacy systems that previously assumed other encodings. Therefore, by changing this default value, we try to match expectations of the largest number of users of our software. If you are using one of these outputs, make sure to test this assumptions with your listners' clients. If needed, the characters encoding can be set to a different value using the operator's parameters. ### Decoder names Decoder names have been converted to lowercase. If you were relying on specific settings for decoders priority/ordering, you will need to convert them to lowercase, for instance: ``` settings.decoder.decoders.set(["FFMPEG"]) ``` becomes: ``` settings.decoder.decoders.set(["ffmpeg"]) ``` Actually, because of the above change in references, this even becomes: ``` settings.decoder.decoders := ["ffmpeg"] ``` ### `strftime` Add file-based operators do not support `strftime` type conversions out of the box anymore. Instead, you should use explicit conversions using `time.string`. This means that this script: ```liquidsoap output.file("/path/to/file%H%M%S.wav", ...) ``` becomes: ```liquidsoap output.file({time.string("/path/to/file%H%M%S.wav")}, ...) ``` ### Other breaking changes - `reopen_on_error` and `reopen_on_metadata` in `output.file` an related outputs are now callbacks. - `request.duration` now returns a `nullable` float, `null` being value returned when the request duration could not be computed. - `getenv` (resp. `setenv`) has been renamed to `environment.get` (resp. `environment.set`). ## From 2.0.x to 2.1.x ### Regular expressions First-class [regular expression](language.html#regular-expressions) are introduced and are used to replace the following operators: - `string.match(pattern=<regexp>, <string>` is replaced by: `r/<regexp>/.test(<string>)` - `string.extract(pattern=<regexp>, <string>)` is replaced by: `r/<regexp>/.exec(<string>)` - `string.replace(pattern=<regexp>, <string>)` is replaced by: `r/<regexp>/g.replace(<string>)` - `string.split(separator=<regexp>, <string>)` is replaced by: `r/<regexp>/.split(<string>)` ### Partial application In order to improve performance, avoid some programming errors and simplify the code, the support for partial application of functions was removed (from our experience it was not used much anyway). This means that you should now provide all required arguments for functions. The behavior corresponding to partial application can of course still be achieved by explicitly abstracting (with `fun(x) -> ...`) over some arguments. For instance, suppose that we defined the addition function with two arguments with ```liquidsoap def add(x,y) = x + y end ``` and defined the successor function by partially applying it to the first argument ```liquidsoap suc = add(1) ``` We now need to explicitly provide the second argument, and the `suc` function should now be defined as ```liquidsoap suc = fun(x) -> add(1, x) ``` or ```liquidsoap def suc(x) = add(1, x) end ``` ### JSON parsing JSON parsing was greatly improved and is now much more user-friendly. You can check out our detailed presentation [here](json.html). ### Runtime evaluation Runtime evaluation of strings has been re-implemented as a type-safe eval `let` decoration. You can now do: ```liquidsoap let eval x = "[1,2,3]" ``` And, just like with JSON parsing, the recommended use is with a _type annotation_: ```liquidsoap let eval (x: [int]) = "[1,2,3]" ``` ### Deprecations and breaking changes - The argument `streams_info` of `output.file.hls` is now a record. - Deprecated argument `timeout` of `http.*` operators. - `source.on_metadata` and `source.on_track` now return a source as this was the case in previous versions, and associated handlers are triggered only when the returned source is pulled - `output.youtube.live` renamed `output.youtube.live.rtmp`, remove `bitrate` and `quality` arguments and added a single encoder argument to allow stream copy and more. - `list.mem_assoc` is replaced by `list.assoc.mem` - `timeout` argument in `http.*` operators is replaced by `timeout_ms`. - `request.ready` is replaced by `request.resolved` ## From 1.4.x to 2.0.0 ### `audio_to_stereo` `audio_to_stereo` should not be required in most situations anymore. `liquidsoap` can handle channels conversions transparently now! ### `auth` function in `input.harbor` The type of the `auth` function in `input.harbor` has changed. Where before, you would do: ```liquidsoap def auth(user, password) = ... end ``` You would now do: ```liquidsoap def auth(params) user = params.user password = params.password ... end ``` ### Type errors with lists of sources Now that sources have their own methods, the actual list of methods attached to each source can vary from one to the next. For instance, `playlist` has a `reload` method but `input.http` does not. This currently confuses the type checker and leads to errors that look like this: ```liquidsoap At script.liq, line xxx, char yyy-zzz: Error 5: this value has type _ * source(audio=?A, video=?B, midi=?C) .{ time : () -> float, shutdown : () -> unit, fallible : bool, skip : () -> unit, seek : (float) -> float, is_active : () -> bool, is_up : () -> bool, log : {level : (() -> int?).{set : ((int) -> unit)} }, self_sync : () -> bool, duration : () -> float, elapsed : () -> float, remaining : () -> float, on_track : ((([string * string]) -> unit)) -> unit, on_leave : ((() -> unit)) -> unit, on_shutdown : ((() -> unit)) -> unit, on_metadata : ((([string * string]) -> unit)) -> unit, is_ready : () -> bool, id : () -> string, selected : (() -> source(audio=?D, video=?E, midi=?F)?) } but it should be a subtype of the type of the value at radio.liq, line 122, char 2-21 _ * _.{reload : _} ``` In such cases, we recommend to give a little nudge to the typechecker by using the `(s:source)` type annotation where a list of source is causing the issue. For instance: ```liquidsoap s = fallback([ (s1:source), (s2:source), (s3:source) ]) ``` This tells the type checker not to worry about the source methods and just focus on what matters, that they are actually sources.. 🙂 ### Http input and operators In order to provide as much compatibility as possible with the different HTTP protocols and implementation, we have decided to delegate HTTP support to external libraries which have large scale support and implementation. This means that, if you have installed `liquidsoap` using `opam`: - You need to install the `ocurl` package to enable all HTTP request operators, `http.get`, `http.post`, `http.put`, `http.delete` and `http.head` - You need to install the `ffmpeg` package (version `1.0.0` or above) to enable `input.http` - You do not need to install the `ssl` package anymore to enable their `https` counter-part. These operators have been deprecated. ### Crossfade The parameters for `cross` transitions was changed to take advantage of the new module system. Instead of passing multiple arguments related to the ending and starting track, those are regrouped into a single record. So, if you had a transition like this: ```liquidsoap def transition( ending_dB_level, starting_dB_level, ending_metadata, starting_metadata, ending_source, starting_source) = ... end ``` You would now do: ```liquidsoap def transition(ending, starting) = # Now you can use: # - ending.db_level, ending.metadata, ending.source # - starting.db_level, starting.metadata, starting.source ... end ``` ### Settings Settings are now exported as records. Where you would before write: ```liquidsoap set("decoder.decoders", ["MAD", "FFMPEG"]) ``` You can now write: ```liquidsoap settings.decoder.decoders.set(["MAD", "FFMPEG"]) ``` Likewise, to get a setting's value you can now do: ```liquidsoap current_decoders = settings.decoder.decoders() ``` This provides many good features, in particular type-safety. For convenience, we have added shorter versions of the most used settings. These are all shortcuts to their respective `settings` values: ```liquidsoap log.level.set(4) log.file.set(true) log.stdout.set(true) init.daemon.set(true) audio.samplerate.set(48000) audio.channels.set(2) video.frame.width.set(720) video.frame.height.set(1280) ``` The `register` operator could not be adapted to this new API and had to be removed, however, backward-compatible `set` and `get` operators are provided. Make sure to replace them as they should be removed in a future version. ### Metadata insertion The function `insert_metadata` does not return a pair anymore, but a source with a method named `insert_metadata`. This means that you should change the code ```liquidsoap fs = insert_metadata(s) # The function to insert metadata f = fst(ms) # The source with inserted metadata s = snd(ms) ... # Using the function f([("artist", "Bob")]) ... # Using the source output.pulseaudio(s) ``` to ```liquidsoap s = insert_metadata(s) ... # Using the function s.insert_metadata([("artist", "Bob")]) ... # Using the source output.pulseaudio(s) ``` ### Request-based queueing Queueing for request-based sources has been simplified. The `default_duration` and `length` have been removed in favor of a simpler implementation. You can now pass a `prefetch` parameter which tells the source how many requests should be queued in advance. Should you need more advanced queueing strategy, `request.dynamic.list` and `request.dynamic` now export functions to retrieve and set their own queue of requests. ### JSON import/export `json_of` has been renamed `json.stringify` and `of_json` has been renamed `json.parse`. JSON export has been enhanced with a new generic json object export. Associative lists of type `(string, 'a)` are now exported as lists. See our [JSON documentation page](json.html) for more details. Convenience functions have been added to convert metadata to and from JSON object format: `metadata.json.stringify` and `metadata.json.parse`. ### Returned types from output operators Starting with liquidsoap `2.0.0`, output operators return the empty value `()` while they previously returned a source. This helps enforce the fact that outputs should be end-points of your scripting graphs. However, in some cases, this can cause issues while migrating old scripts, in particular if the returned value of an output was used in the script. The way to fix this is to apply your operator to the source directly underneath the output. For instance, the following clock assignment: ```liquidsoap s = ... clock.assign_new([output.icecast(..., s)]) ``` Should now be written: ```liquidsoap s = ... clock.assign_new([s], ...) output.icecast(..., s) ``` ### Deprecated operators Some operators have been deprecated. For most of them, we provide a backward-compatible support but it is good practice to update your script. You should see logs in your script when running deprecated operatords. Here's a list of the most important ones: - `playlist.safe` is replaced by: `playlist(mksafe(..))` - `playlist.once` is replaced by: `playlist`, setting `reload_mode` argument to `"never"` and `loop` to `false` - `rewrite_metadata` should be rewritten using `metadata.map` - `fade.initial` and `fade.final` are not needed anymore - `get_process_output` is replaced by: `process.read` - `get_process_lines` is replaced by: `process.read.lines` - `test_process` is replaced by: `process.test` - `system` is replaced by: `process.run` - `add_timeout` is replaced by: `thread.run.recurrent` - `on_blank` is replaced by: `blank.detect` - `skip_blank` is replaced by: `blank.skip` - `eat_blank` is replaced by: `blank.eat` - `strip_blank` is replaced by: `blank.strip` - `which` is replaced by: `file.which` - `register_flow`: flow is no longer maintained - `empty` is replaced by: `source.fail` - `file.unlink` is replaced by: `file.remove` - `string.utf8.escape` is replaced by: `string.escape` - `metadata.map` is replaced by: `metadata.map` ### Windows build The windows binary is statically built and, for this reason, we cannot enable both the `%ffmpeg` encoder and any encoder that uses the same underlying libraries, for instance `libmp3lame` for `mp3` encoding. The technical reason is that both libraries import the same C symbols, which makes compilation fail. The `%ffmpeg` encoder provides all the functionalities of the internal encoders that conflict with it along with many more format we do not support otherwise. For this reason, it was decided to enable the `%ffmpeg` encoder and disable all other encoders. This means that, if you were previously using a different encoder than `%ffmpeg`, you will need to adapt your script to use it. For instance, for mp3 encoding with variable bitrate: ```liquidsoap %ffmpeg(format="mp3", %audio(codec="libmp3lame", q=7)) ``` ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/multitrack.md����������������������������������������������������������0000664�0000000�0000000�00000030257�14773033502�0020623�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Multitrack support Starting with version `2.2.0`, liquidsoap now supports track operations, making it possible to manipulate data at the track level, including demuxing, remuxing, encoding, decoding, applying filters and more! **Only the FFmpeg decoder and encoder supports multitrack**. This means that you need to have `liquidsoap` compiled with the FFmpeg support to be able to decode or encode sources with multiple audio/video tracks. Support for track muxing and demuxing and track-level operators, however, does not require the FFmpeg support but, without it, all decoders and outputs are limited to at most one `audio` and one `video` track. ## Multitrack sources Liquidsoap sources can have multiple tracks, such as an english language audio track and a french language audio track. The number of tracks in a source is determined by how you use it. For instance, if you have a file `movie.mkv` with two audio tracks and one video track, you can create a source `s` with it using the `single` operator (or `playlist`, `request.dynamic` etc): ```liquidsoap s = single("/path/to/movie.mkv") ``` By default, `liquidsoap` decodes _only_ the track that you tell it to pick. So, if you output this source as an output with only one audio track, it will happily do so: ```{.liquidsoap include="multitrack.liq"} ``` Resulting in the following logs: ``` [output_file:3] Content type is {audio=ffmpeg.copy,video=ffmpeg.copy}. [decoder.ffmpeg:3] Requested content-type for "/path/to/movie.mkv": {audio=ffmpeg.copy,video=ffmpeg.copy} [decoder.ffmpeg:3] FFmpeg recognizes "/path/to/movie.mkv" as video: {codec: h264, 1920x1038, yuv420p}, audio: {codec: aac, 48000Hz, 6 channel(s)}, audio_2: {codec: aac, 48000Hz, 6 channel(s)} [decoder.ffmpeg:3] Decoded content-type for "/path/to/movie.mkv": {audio=ffmpeg.copy(codec="aac",channel_layout="5.1",sample_format=fltp,sample_rate=48000),video=ffmpeg.copy(codec="h264",width=1920,height=1038,aspect_ratio=1/1,pixel_format=yuv420p)} ``` This shows that the `output.file` source was initialized with expected content-type `{audio=ffmpeg.copy,video=ffmpeg.copy}`, i.e. one audio and one video track, both copied from the original file. This comes from the `%ffmpeg` encoder definition in our script. Then, the `single` file was decoded with the same requested content-type and FFmpeg reported all the details about the file's content, including a second audio track named `audio_2`. Eventually, we picked up only first `audio` and first `video` track and reported a more detailed content-type now that we know the actual content of each track. Now, let's say that we want to also keep the second audio track but convert it to stereo and re-encode it into `aac`. We can then do: ```{.liquidsoap include="multitrack2.liq"} ``` And now we see the following logs: ``` [output_file:3] Content type is {audio=ffmpeg.copy,audio_2=pcm(stereo),video=ffmpeg.copy}. [decoder.ffmpeg:3] Requested content-type for "/path/to/movie.mkv": {audio=ffmpeg.copy,audio_2=pcm(stereo),video=ffmpeg.copy} [decoder.ffmpeg:3] FFmpeg recognizes "/path/to/movie.mkv" as video: {codec: h264, 1920x1038, yuv420p}, audio: {codec: aac, 48000Hz, 6 channel(s)}, audio_2: {codec: aac, 48000Hz, 6 channel(s)} [decoder.ffmpeg:3] Decoded content-type for "/path/to/movie.mkv": {audio=ffmpeg.copy(codec="aac",channel_layout="5.1",sample_format=fltp,sample_rate=48000),audio_2=pcm(5.1),video=ffmpeg.copy(codec="h264",width=1920,height=1038,aspect_ratio=1/1,pixel_format=yuv420p)} ``` Now, we are actually using both audio tracks from `movie.mkv` and one of them is being converted to stereo audio! One thing to keep in mind, however, is that **expected content-type drives the input decoder**. Typically, if, instead of a `single`, you use a `playlist`: ```{.liquidsoap include="multitrack3.liq"} ``` Then all the files in the playlist who do not have at least two `audio` tracks and one `video` track will be rejected by the decoder! Lastly, it is important to keep in mind that **decoders always assume a specific nomenclature for tracks**. The convention when decoding is to name the first audio track `audio`, then `audio_2`, `audio_3` and etc. Likewise for video: `video`, `video_2`, `video_3`. Typically, the following will not work: ```liquidsoap s = playlist("/path/to/playlist") # Copy first audio track and video track # and re-encode second audio track: output.file( fallible=true, %ffmpeg( %audio_fr.copy, %audio_en( channels=2, codec="aac" ), %video.copy ), "/path/to/copy.mkv", s ) ``` This is because the decoder has no way of knowing which of the audio track present in the files in `s` should be matched to `audio_en` and `audio_fr.copy`. One might think that the order in which they are declared in the encoder could be used but this would also be tricky as the decoder could report tracks in different order when decoding different files from the playlist. Also, and perhaps more importantly, tracks can be demuxed and remuxed at will, which also makes us loose the notion of track order. Actually, let's talk about demuxing and remuxing next! ## Tracks demuxing and muxing For any given source, you can extract its tracks using the `source.tracks` operator: ```liquidsoap s = playlist(...) let {audio, video, metadata, track_marks} = source.tracks(s) ``` In the above, `audio` and `video` represent, resp., the `audio` and `video` track from the source `s`. The `metadata` and `track_marks` tracks are special track type that are available in any source and hold, as the name suggests, the source's metadata and track marks. We will see later how this can be used to e.g. drop all tracks from a source (something that used to be done with the `drop_tracks` operator), or select metadata only from a specific source or track. Internally, **a track is a source restricted to a single content-type**. This means that: - When pulling data for a given track, the underlying source is used, potentially also pulling data for its other tracks - Tracks are subject to the same limitations as sources w.r.t. clocks - Tracks, like sources, always have a `metadata` and `track_marks` tracks. The `track.metadata` and `track.track_marks` operators can be used to retrieve them. Tracks can be muxed using the `source` operator. The operator takes a record of tracks and creates a source with them. Tracks can have any name and type except `metadata` and `track_marks` that are reserved for their corresponding track types. ### Add a video track Here's how to add a video track to a source ```{.liquidsoap include="multitrack-add-video-track.liq" to="END"} ``` The above example was purposely written in a longer form to make it more explicit. However, if you wish to just add/replace a track, you can also overload the existing tracks from the first source as follows: ```{.liquidsoap include="multitrack-add-video-track2.liq" to="END"} ``` ### Add a default video track You can also check if a source has a certain track and do something accordingly: ```{.liquidsoap include="multitrack-default-video-track.liq" to="END"} ``` Please note, however, that **tracks available in the playlist sources are determined based on the first decoded file**. If the first file in the playlist is audio-only then the playlist content-type is assumed to be audio-only for the whole playlist and the default video is added to _all decoded files_. To decide on a case-by-case basis, you might need some more advanced coding! ### Merge all tracks As mentioned before, you can also remove the track marks from a source as follows: ```liquidsoap s = playlist(...) # Extract all tracks except track_marks: let {track_marks=_, ...tracks} = source.tracks(s) s = source(tracks) ``` ## Track-level operators Some, but not all, operators have been updated to operate at the track level. They are documented under the `Track` section in [the API documentation](reference.html). More operators might be converted in the future (feel free to file a feature request for those!). For instance, to convert an audio track to mono PCM audio, one can do: ```liquidsoap mono_track = track.audio.mean(audio_track) ``` Likewise, inline encoders are now available at the track level, for instance: ```liquidsoap encoded_audio_track = track.ffmpeg.encode.audio(%ffmpeg(%audio(codec="aac")), audio_track) ``` However, remember that tracks have the same limitations w.r.t. clocks that sources have. Here, in particular, `encoded_audio_track` is in a new clock (due to the fact that ffmpeg inline encoding is not synchronous). Therefore, the following will fail: ```liquidsoap s = playlist(...) let {audio, metadata, track_marks} = source.tracks(s) encoded = source({ audio = track.ffmpeg.encode.audio(%ffmpeg(%audio(codec="aac")), audio), metadata = metadata, track_marks = track_marks }) ``` This is because `metadata` and `track_marks` are tracks from the underlying `s` source, which belongs to a different clock. In this case, you should use the track marks and metadata from the encoded track: ```liquidsoap s = playlist(...) let {audio, metadata, track_marks} = source.tracks(s) encoded_audio = track.ffmpeg.encode.audio(%ffmpeg(%audio(codec="aac")), audio) encoded = source({ audio = encoded_audio, metadata = track.metadata(encoded_audio), track_marks = track_marks(encoded_audio) }) ``` ## Conventions Now that we have seen how we can create any collection of tracks with any possible name, in order to make things work, we need to assume a couple of conventions. **For decoders**, the convention, as explained above, is, when decoding files, to name the first audio track `audio`, then `audio_2`, `audio_3` and etc. Likewise for video: `video`, `video_2`, `video_3`. This is the convention that you should use when demuxing tracks from request-based source: ```liquidsoap s = playlist(...) let {audio, audio_2, video, video_2, video_3} = source.tracks(s) ``` **For encoders**, to drive content-type at runtime, since tracks can be remuxed with any arbitrary name, we need to a way to decide what type of content a track contains, being `audio`, `video` or, potentially `midi` and, planned for later, `subtitles`. This is achieved using the following convention, by order of priority: 1. A `copy` track is any track named `%<track_name>.copy`. We do not need to know the track's content in this case. 2. If a track has `audio_content` or `video_content` as parameter (for instance `%foo(audio_content, ...)`) then it is considered, resp., `audio` or `video`. 3. If the track name has `audio` or `video` in it (for instance `%dolby_audio_fr`) then it is considered, resp., `audio` or `video` 4. If the track codec is hardcoded (for instance (`%foo(codec="aac", ...)`) then the codec is used to detect the content. For instance, imagine that you want to encode a source with a `fr` and `en` audio track and a `director_cut` video track, you can do the following: ```liquidsoap output.file( %ffmpeg( %en(codec="aac"), %fr(codec="aac"), %director_cut(codec="libx264") ), "/path/to/copy.mkv", s ) ``` This works because each of the codec used in these tracks can be mapped to a specific content-type. Now, imagine that you actually want to use a variable for the codec of the `en` and `director_cut` track. In this case, you can do: ```liquidsoap output.file( %ffmpeg( %en(audio_content, codec=audio_codec) %fr(codec="aac"), %director_cut(video_content, codec=video_codec) ), "/path/to/copy.mkv", s ) ``` This informs `liquidsoap` what type of content these tracks contain. However, you might also opt for a more explicit track naming scheme. Something like: ```liquidsoap output.file( %ffmpeg( %audio_en(codec=audio_codec), %audio_fr(codec="aac"), %director_cut_video(codec=video_codec) ), "/path/to/copy.mkv", s ) ``` In this case, `liquidsoap` assumes that the track with `audio` in their name are indeed audio track and the same goes for video tracks. Lastly, these naming conventions have no bearing for the `FFmpeg` encoder. At the FFmpeg encoder level, tracks are identified by an integer and stored in the order they are declared in the `%ffmpeg` encoder. This means that, once encoded and saved to a file, track names internal to liquidsoap are not saved by the FFmpeg encoder and, instead, when decoding the file, you will get `audio`, `audio_2`, `video` and etc. �������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/on2.md�����������������������������������������������������������������0000664�0000000�0000000�00000000776�14773033502�0017145�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������Savonet was at the [ON2: Test Signals](http://testsignals.org/) conference in Berlin, on October 22-23 2010.

Remaining unknown [stream types](stream_contents.html) are forced according to `frame.*.channels` settings, [clocks](clock.html) are assigned (but unknown clocks may remain) and some sources are checked to be [infallible](source.htmls). Each of these steps may raise an error. - **Collection**: Unknown clocks become the default clock so that all sources are assigned to one clock. Active sources newly attached to clocks are initialized for streaming, shutdown sources are detached from their clocks, and clocks are started or destroyed as needed. Streaming has started. Usually, liquidsoap is ran by passing one or several scripts and expressions to execute. Those expressions set up some sources, and outputs typically don't change anymore. If those initially provided active sources fail to be initialized (invalid parameter, fail to connect, etc.) liquidsoap will terminate with an error. It is however possible to **dynamically** create active sources, through registered server commands, event handlers, etc. They will be initialized and run as statically created ones. In **interactive** mode (passing the `--interactive` option) it is also possible to input expressions in a liquidsoap prompt, and their execution can trigger the creation of new outputs. Outputs can be deactivated using `source.shutdown()`: they will stop streaming and will be destroyed. The full liquidsoap instance can be shutdown using the `shutdown()` command. ����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/playlist_parsers.md����������������������������������������������������0000664�0000000�0000000�00000007432�14773033502�0022043�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Playlist parsers Liquidsoap supports various playlists formats. Those formats can be used for `playlist` sources, `input.http` streams and manually using `request.create`. ## Supported formats Most supported playlists format are _strict_, which means that the decoder can be sure that is has found a correct playlist for that format. Some other format, such as `m3u`, however, may cause _false positive_ detections. All formats are identified by their _mime-type_ or _content-type_. Supported formats are the following: - Text formats: - `audio/x-scpls`: [PLS format](http://en.wikipedia.org/wiki/PLS_%28file_format%29), **strict** - `application/x-cue`: [CUE format](http://en.wikipedia.org/wiki/.cue), **strict**. This format's usage is described below. - `audio/x-mpegurl`, `audio/mpegurl`: [M3U](http://en.wikipedia.org/wiki/M3u), **non strict** - Xml formats: - `video/x-ms-asf`, `audio/x-ms-asx`: [ASX](http://en.wikipedia.org/wiki/Advanced_Stream_Redirector), **strict** - `application/smil+xml`, `application/smil+xml`, [SMIL](http://en.wikipedia.org/wiki/Synchronized_Multimedia_Integration_Language), **strict** - `application/xspf+xml`, [XSPF](http://en.wikipedia.org/wiki/Xspf), **strict** - `application/rss+xml`, [Podcast](http://en.wikipedia.org/wiki/Podcast), **strict** Playlist format is driven by the **Content-Type** and **Content-Disposition** HTTP headers _(see m3u example below)_. You should make sure that your HTTP endpoint returns appropriate values for those. As last resort, you should be able to use the `settings.http.mime.extnames` settings to add or adjust support for your endpoint's mime-type if liquidsoap supports its corresponding playlist format. See for instance issue [#3451](https://github.com/savonet/liquidsoap/issues/3451). ## Usage Playlist files are parsed automatically when used in a `playlist` or `input.http` operator. Each of these two operators has specific options to specify how to pick up a track from the playlist, _e.g._ pick a random track, the first one etc. Additionally, you can also manually parse and process a playlist using `request.create` and `request.resolve` and some programming magic. You can check the code source for `playlist.reloadable` in our standard library for a detailed example. ### Remote M3U playlist example Here is an example of a m3u playlist being read from nodejs/express . liquidsoap script: ```liquidsoap #!/usr/local/bin/liquidsoap p = playlist(reload=10, "http://localhost:8080/radio/playlists/0/playlist.m3u") ``` nodejs/express app: ```js import express from "express"; const app = express(); app.get("/radio/playlists/:id/playlist.m3u", async (req, res) => { const playlist = ["/media/foo.mp3", "/media/bar.mp3"]; // Liquidsoap will use the file extension from the `Content-Disposition` header to guess // the playlist format res.set( "Content-Disposition", `attachment; filename="playlist-${req.params.id}.m3u"`, ); // Otherwise, it will try to guess the file extension from the playlist mime-type. res.set("Content-Type", "audio/x-mpegurl"); res .send(playlist.join("\r\n") + "\r\n") .status(200) .end(); }); const server = app.listen(8080); ``` ## Special case: CUE format The CUE format originates from CD burning programs. They describe the set of tracks of a whole CD and are accompanied by a single file containing audio data for the whole CD. By default, the CUE playlist parser will add metadata from cue-in and cue-out points for each track described in the playlist, which are automatically handled with source-base operators such as `playlist`. The metadata added for cue-in and cue-out positions can be customized using the following configuration keys: ```liquidsoap settings.playlists.cue_in_metadata := "liq_cue_in" settings.playlists.cue_out_metadata := "liq_cue_out" ``` ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/presentations.md�������������������������������������������������������0000664�0000000�0000000�00000003122�14773033502�0021331�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Presentations about Liquidsoap ## Liquidshop In January 2021, we organized [the _Liquidshop_, a workshop around Liquidsoap](http://www.liquidsoap.info/liquidshop/), where you can find lots of presentations around Liquidsoap.

We are not speaking here about the encoding of streams, which usually takes the vast majority of the spent computing power, but of functions written directly in Liquidsoap. In order to understand those better, Liquidsoap has a _profiler_ which records all the function calls. It can be enabled with ```liquidsoap profiler.enable() ``` (or by passing the `--profile` commandline flag of Liquidsoap) and the statistics can be obtained with ```liquidsoap print(profiler.stats.string()) ``` It will output something like ``` function self total calls + 0.359139919281 0.359139919281 302000 list.add 0.324638843536 442.74707818 202000 if 0.242718935013 442.951756954 102002 list.cons 0.230906486511 442.277146816 101000 ``` where each lines consists of a function, the time spent in the functions, the time spent in the function and the functions it has called and the number of calls to the function. �����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/prometheus.md����������������������������������������������������������0000664�0000000�0000000�00000010455�14773033502�0020635�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Prometheus reporting When compiled with optional support for [mirage/prometheus](https://github.com/mirage/prometheus), `liquidsoap` can export [prometheus](https://prometheus.io/) metrics. The basic settings to enable exports are: ```{.liquidsoap include="prometheus-settings.liq"} ``` Common metrics, namely `gauge`, `counter` and `summary` are provided via the script language, as well as a specialized operator to track source's latencies. A fully-featured implementation can be found at [mbugeia/srt2hls](https://github.com/mbugeia/srt2hls) ## Basic operators The 3 basic operators are: - `prometheus.counter` - `prometheus.gauge` - `prometheus.summary` They share a similar type and API, which is as follows: ```liquidsoap (help : string, ?namespace : string, ?subsystem : string, labels : [string], string) -> (label_values : [string]) -> (float) -> unit ``` This type can be a little confusing. Here's how it works: 1. First, one has to create a metric factory of a given type. For instance: ```{.liquidsoap include="prometheus-callback.liq" from="A0" to="A1"} ``` 2. Then, the metric factory can be used to instantiate speific metrics by passing the label's values: ```{.liquidsoap include="prometheus-callback.liq" from="B0" to="B1"} ``` The returned function is a setter for this metric, i.e. - For `gauge` metrics, it sets the gauge value - For `counter` metrics, it increases the counter value - For `summary` metrics, it registers an observation Finally, the programmer can now use that callback to set the metric as desired. For instance here: ```{.liquidsoap include="prometheus-callback.liq" from="C0"} ``` ## `prometheus.latency` The `prometheus.latency` operator provides prometheus metrics describing the internal latency of a given source. It is fairly easy to use: ```liquidsoap s = (...) prometheus.latency(s) ``` The metrics are computed over a sliding window that can be defined as a parameter of the operator. Exported metrics are: ``` # Input metrics: liquidsoap_input_latency{...} <value> liquidsoap_input_max_latency{...} <value> liquidsoap_input_peak_latency{...} <value> # Output metrics: liquidsoap_outputput_latency{...} <value> liquidsoap_output_max_latency{...} <value> liquidsoap_output_peak_latency{...} <value> # Overall metrics: liquidsoap_overall_latency{...} <value> liquidsoap_overall_max_latency{...} <value> liquidsoap_overall_peak_latency{...} <value> ``` The 3 different groups of values are: - **input**: metrics related to the time it takes to generate audio data - **output**: metrics related to the time it takes to output (encode and send) audio data - **overall**: the sum of all previous two groups Each group of metrics is divided into 3 subsets: - Mean latency value over the sliding window - Max latency value over the sliding window - Peak latency since start Latencies are reported over a frame's duration, which is typically around `0.04` seconds. Thus, in a situation where liquidsoap does not observe latency catch-ups, the overall mean latency `liquidsoap_overall_latency` should always be near that value. These metrics can be used to report and track the source of latencies and catch-ups while streaming. Typically, if a source starts taking too much time to generate its audio data, this should be reflects in the `input` latencies. Likewise for encoding and network output. Keep in mind, however, that enabling these metrics can have a CPU cost. It is rather small with a couple of sources but can increase with the number of sources being tracked. The user of these metrics is advised to keep track of CPU usage while ramping up on using them. ## OCaml specific metrics The prometheus binding used by `liquidsoap` also exports default OCaml-related metrics. They are as follows: ``` ocaml_gc_allocated_bytes <value> ocaml_gc_compactions <value> ocaml_gc_heap_words <value> ocaml_gc_major_collections <value> ocaml_gc_major_words <value> ocaml_gc_minor_collections <value> ocaml_gc_top_heap_words <value> process_cpu_seconds_total <value> ``` These metrics can be useful when debugging issues with `liquidsoap`, in particular to track is an observed increase in memory usage is related to OCaml memory allocation or not. More than often, if the increase is not related to OCaml, it can be safely assumed that the issue might come from an external library used by `liquisoap`. �������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/protocols-presentation.md����������������������������������������������0000664�0000000�0000000�00000004503�14773033502�0023174�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Protocols Protocols in liquidsoap are used to resolve requests URIs. The syntax is: `protocol:arguments`, for instance: `http://www.example.com`, `say:Something to say` etc. Most protocols are written using the script language. You can look at the file `protocols.liq` for a list of them. In particular, the `process:` protocol can use an external command to prepare resolve a request. Here's an example using the AWS command-line to download a file from S3: ```liquidsoap def s3_protocol(~rlog,~maxtime,arg) = extname = file.extension(leading_dot=false,dir_sep="/",arg) [process_uri(extname=extname,"aws s3 cp s3:#{arg} $(output)")] end protocol.add("s3",s3_protocol,doc="Fetch files from s3 using the AWS CLI", syntax="s3://uri") ``` Each protocol needs to register a handler, here the `s3_protocol` function. This function takes the protocol arguments and returns a list of new requests or files. Liquidsoap will then call this function, collect the returned list and keep resolving requests from the list until it finds a suitable file. This makes it possible to create your own custom resolution chain, including for instance cue-points. Here's an example: ```liquidsoap def cue_protocol(~rlog,~maxtime,arg) = [process_uri(extname="wav",uri=uri,"ffmpeg -y -i $(input) -af -ss 10 -t 30 $(output)")] end protocol.add("cue_cut",cue_protocol) ``` This protocol returns 30s of data from the input file, stating at the 10s mark. Likewise, you can apply a normalization program: ```liquidsoap def normalization_protocol(~rlog,~maxtime,arg) = # "normalize" command here is just an example.. [process_uri(extname="wav",uri=arg,"normalize $(inpuit)")] end protocol.add("normalize",normalization_protoco) ``` Now, you can push requests of the form: ``` normalize:cue_cut:http://www.server.com/file.mp3 ``` and the file will be cut and normalized before being played by liquidsoap. When defining custom protocols, you should pay attention to two variables: - `rlog` is the logging function. Messages passed to this function will be registered with the request and can be used to debug any issue - `maxtime` is the maximum time (in UNIX epoch) that the requests should run. After that time, it should return and be considered timed out. You may want to read from `protocols.liq` to see how to enforce this when calling external processes. ���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/publications.md��������������������������������������������������������0000664�0000000�0000000�00000002343�14773033502�0021133�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������--- header-includes: | \DeclareUnicodeCharacter{03BB}{$\lambda$} ... # The theory behind Liquidsoap ## Publications ### Liquidsoap: a High-Level Programming Language for Multimedia Streaming Many of the advanced features of the Liquidsoap language are described in [Liquidsoap: a High-Level Programming Language for Multimedia Streaming](/assets/docs/bbm10.pdf). The article details in particular Liquidsoap's handling of heterogeneous stream contents (e.g. audio and video), as well as the model for clocks in the language. ### De la webradio lambda à la λ-webradio The first published presentation of Liquidsoap was made in [De la webradio lambda à la λ-webradio](/assets/docs/bm08.pdf) (_Baelde D. and Mimram S. in proceedings of Journées Francophnes des Languages Applicatifs (JFLA), pages 47-61, 2008_) -- yes, it's in French, sorry. It gives a broad description of the Liquidsoap tool and explains the theory behind the language, which is formalized as a variant of the typed λ-calculus with labels and optional arguments. The article describes the typing inference algorithm as well as some properties of the language (confluence) and of typing (subject reduction, admissible rules, termination of typed terms). ���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/quick_start.md���������������������������������������������������������0000664�0000000�0000000�00000024501�14773033502�0020770�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Quickstart ## The Internet radio toolchain [Liquidsoap](index.html) is a general audio stream generator, but is mainly intended for Internet radios. Before starting with the proper Liquidsoap tutorial let's describe quickly the components of the internet radio toolchain, in case the reader is not familiar with it. The chain is made of: - the stream generator (Liquidsoap, [ices](https://www.icecast.org/ices/), or for example a DJ-software running on your local PC) which creates an audio stream (Ogg Vorbis or MP3); - the streaming media server ([Icecast](http://www.icecast.org), [HLS](https://en.wikipedia.org/wiki/HTTP_Live_Streaming) (via a HTTP server), ...) which relays several streams from their sources to their listeners; - the media player (iTunes, VLC, a web browser, ...) which gets the audio stream from the streaming media server and plays it to the listener's speakers. ![Internet radio toolchain](/assets/img/schema-webradio-inkscape.png) The stream is always passed from the stream generator to the server, whether or not there are listeners. It is then sent by the server to every listener. The more listeners you have, the more bandwidth you need. If you use Icecast, you can broadcast more than one audio feed using the same server. Each audio feed or stream is identified by its "mount point" on the server. If you connect to the `foo.ogg` mount point, the URL of your stream will be [http://localhost:8000/foo.ogg](http://localhost:8000/foo.ogg) -- assuming that your Icecast is on localhost on port 8000. If you need further information on this you might want to read Icecast's [documentation](http://www.icecast.org). A proper setup of a streaming server is required for running Liquidsoap. Now, let's create an audio stream. ## Starting to use Liquidsoap We assume that you have a fully installed Liquidsoap. In particular the library `stdlib.liq` and its accompanying scripts should have been installed, otherwise Liquidsoap won't know the operators which have been defined there. ### Sources A stream is built with Liquidsoap by using or creating sources. A source is a media stream containing audio and/or video, track marks and metadata. In the following picture we represent a stream which has at least three tracks (one of which starts before the snapshot), and a few metadata packets (notice that they do not necessarily coincide with new tracks). ![A stream](/assets/img/stream.png) Liquidsoap provides many functions for creating sources from scratch (e.g. `playlist`), and also for creating complex sources by putting together simpler ones (e.g. `switch` in the following example). Eventually, sources are plugged into outputs (typically named `output.*`) which continuously pull the source's content and output it to speakers, to a file, to a streaming server, etc. These outputs what brings life into your sources. ### That source is fallible! A couple of things can go wrong in your streaming system. In Liquidsoap, we say that a source is _infallible_ if it is always available. Otherwise, it is _fallible_, meaning that something could go wrong and the source would not be available. By default, an output requires that its input source is infallible, otherwise it complains that "That source is fallible!" For example, a normal `playlist` is fallible. Firstly, because it could contain only invalid files, or at least spend too much time on invalid files to be able to prepare a valid one on time. Moreover, a playlist could contain remote files, which may not be accessible quickly at all times. A queue of user requests is another example of fallible source. Also, if `file.ogg` is a valid local file, then `single("file.ogg")` is an infallible source. When an output complains about its source being fallible, you have to turn it into an infallible one. Many solutions are available. The function `mksafe` takes a source and returns an infallible source, streaming silence when the input stream becomes unavailable. In a radio-like stream, silence is not the preferred solution, and you will probably prefer to `fallback` on an infallible "security" source: ```liquidsoap fallback([your_fallible_source_here, single("failure.ogg")]) ``` Finally, if you do not care about failures, you can pass the parameter `fallible=true` to most outputs (or pass the option `--no-fallible-check` to Liquidsoap). In that case, the output will accept a fallible source, and stop whenever the source fails and restart when it is ready to produce data again. ## One-line expressions Liquidsoap is a scripting language. Many simple setups can be achieved by evaluating one-line expressions. ### Playlists In the first example we'll play a playlist. Let's put a list of audio files in `playlist.pls`: one filename per line, lines starting with a `#` are ignored. You can also put remote files' URLs, if your liquidsoap has [support](help.html#plugins) for the corresponding protocols. Then just run: ```liquidsoap liquidsoap 'output(playlist("playlist.pls"))' ``` Other playlist formats are supported, such as M3U and, depending on your configuration, XSPF. Instead of giving the filename of a playlist, you can also use a directory name, and liquidsoap will recursively look for audio files in it. Depending on your configuration, the output `output` will use AO, Alsa or OSS, or won't do anything if you do not have support for these libs. In that case, the next example is for you. ### Streaming out to a server **Note:** in the following, we assume that you have installed the following optional dependencies: - `cry` for icecast output - `vorbis` for ogg/vorbis encoding - `ffmpeg` for ffmpeg encoding Liquidsoap is capable of playing audio on your speakers, but it can also send audio to a streaming server such as Icecast or Shoutcast. One instance of liquidsoap can stream one audio feed in many formats (and even many audio feeds in many formats!). You may already have an Icecast server. Otherwise you can install and configure your own Icecast server. The configuration typically consists in setting the admin and source passwords, in `/etc/icecast2/icecast.xml`. These passwords should really be changed if your server is visible from the hostile internet, unless you want people to kick your source as admins, or add their own source and steal your bandwidth. We are now going to send an audio stream, encoded as Ogg Vorbis, to an Icecast server: ```liquidsoap liquidsoap \ 'output.icecast(%vorbis, host = "localhost", port = 8000, password = "hackme", mount = "liq.ogg", mksafe(playlist("playlist.m3u")))' ``` The main difference with the previous is that we used `output.icecast` instead of `output`. The second difference is the use of the `mksafe` which turns your fallible playlist source into an infallible source. If you want to use HLS instead for streaming, you can do: ```liquidsoap liquidsoap \ 'output.file.hls( "/path/to/hls/directory", [("aac", %ffmpeg( format="mpegts", %audio(codec="aac", b="128k") ))], mksafe(playlist("playlist.m3u")))' ``` Once started, this will place all the files required for HLS stream into the local path `"/path/to/hls/directory"` which you can then server over HTTP. The HLS output has many interesting options, including callbacks to upload its files and more. See the [HLS Output](hls_output.html) page for more details. ### Input from another streaming server Liquidsoap can use another stream as an audio source. This may be useful if you do some live shows. ```liquidsoap liquidsoap \ 'output(input.http("https://icecast.radiofrance.fr/fip-hifi.aac"))' ``` ### Input from the soundcard If you're lucky and have a working ALSA support, try one of these... but beware that ALSA may not work out of the box. ```liquidsoap liquidsoap 'output.alsa(input.alsa())' ``` ```liquidsoap liquidsoap 'output.alsa(input.alsa())' ``` ### Other examples You can play with many more examples. Here are a few more. To build your own, lookup the [API documentation](reference.html) to check what functions are available, and what parameters they accept. ```liquidsoap # Listen to your playlist, but normalize the volume liquidsoap 'output(normalize(playlist("playlist_file")))' ``` ```liquidsoap # ... same, but also add smart cross-fading liquidsoap 'output(crossfade( normalize(playlist("playlist_file"))))' ``` ## Script files We have seen how to create a very basic stream using one-line expressions. If you need something a little bit more complicated, they will prove uneasy to manage. In order to make your code more readable, you can write it down to a file, named with the extension `.liq` (eg: `myscript.liq`). To run the script: ```liquidsoap liquidsoap myscript.liq ``` On UNIX, you can also put `#!/path/to/your/liquidsoap` as the first line of your script ("shebang"). Don't forget to make the file executable: ``` chmod u+x myscript.liq ``` Then you'll be able to run it like this: ``` ./myscript.liq ``` Usually, the path of the liquidsoap executable is `/usr/bin/liquidsoap`, and we'll use this in the following. ## A simple radio In this section, we build a basic radio station that plays songs randomly chosen from a playlist, adds a few jingles (more or less one every four songs), and output an Ogg Vorbis stream to an Icecast server. Before reading the code of the corresponding liquidsoap script, it might be useful to visualize the streaming process with the following tree-like diagram. The idea is that the audio streams flows through this diagram, following the arrows. In this case the nodes (`fallback` and `random`) select one of the incoming streams and relay it. The final node `output.icecast` is an output: it actively pulls the data out of the graph and sends it to the world. ![Graph for 'basic-radio.liq'](/assets/img/basic-radio-graph.png) ```{.liquidsoap include="basic-radio.liq"} ``` ## What's next? You can first have a look at a [more complex example](complete_case.html). There is also a second tutorial about [advanced techniques](advanced.html). You should definitely learn [how to get help](help.html). If you know enough liquidsoap for your use, you'll only need to refer to the [scripting reference](reference.html), or see the [cookbook](cookbook.html). At some point, you might read more about Liquidsoap's [scripting language](language.html). For a better understanding of liquidsoap, it is also useful to read a bit about the notions of [sources](sources.html) and [requests](requests.html). �����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/radiopi.md�������������������������������������������������������������0000664�0000000�0000000�00000004163�14773033502�0020070�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# RadioPi [RadioPi](http://www.radiopi.org) is the web radio of the ECP (Ecole Centrale de Paris). RadioPi runs many channels. There are topical channels (Reggae, Hip-Hop, Jazz, ...). On top of that, they periodically broadcast live shows, which are relayed on all channels. We met a RadioPi manager right after having released Liquidsoap 0.2.0, and he was seduced by the system. They needed quite complex features, which they were at that time fulfilling using dirty tricks, loads of obfuscated scripts. Using Liquidsoap now allow them to do all they want in an integrated way, but also provided new features. ### The migration process Quite easy actually. They used to have many instances Ices2, each of these calling a Perl script to get the next song. Other scripts were used for switching channels to live shows. Now they have this single Liquidsoap script, no more. It calls external scripts to interact with their web-based song scheduling system. And they won new features: blank detection and distributed encoding. The first machine gets its files from a ftp server opened on the second machine. Liquidsoap handles download automatically. Each file is given by an external script, `radiopilote-getnext`, whose answer looks as follows (except that it's on a single line): ``` annotate:file_id="3541",length="400.613877551",\ type="chansons",title="John Holt - Holigan",\ artist="RadioPi - Canal reggae",\ album="Studio One SeleKta! - Album Studio 1 12",\ canal="reggae":ftp://***:***@host/files/3541.mp3 ``` Note that we use annotate to pass some variables to liquidsoap... ```{.liquidsoap include="radiopi.liq"} ``` The other machine has a similar configuration except that files are local, but this is exactly the same for liquidsoap ! Using harbor, the live connects directly to liquidsoap, using port `8000` (icecast runs on port `8080`). Then, liquidsoap starts a relay to the other encoder, and both switch their channels to the new live. Additionally, a file output is started upon live connection, in order to backup the stream. You could also add a relay to icecast in order to manually check what's received by the harbor. �������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/reference-header.md����������������������������������������������������0000664�0000000�0000000�00000001552�14773033502�0021624�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Liquidsoap scripting language reference The **Source / ...** categories contain all functions that return sources. The **Input** functions are those which build elementary sources (playing files, synthesizing sound, etc.). The **Output** functions are those which take a source and register it for being streamed to the outside (file, soundcard, audio server, etc.). The **Visualization** functions are experimental ones that let you visualize in real-time some aspects of the audio stream. The **Sound Processing** functions are those which basically work on the source as a continuous audio stream. They would typically be mixers of streams, audio effects or analysis. Finally, **Track Processing** functions are basically all others, often having a behaviour that depends on or affects the extra information that liquidsoap puts in streams: track limits and metadata. ������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/release-assets.md������������������������������������������������������0000664�0000000�0000000�00000001101�14773033502�0021346�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������This release provides liquidsoap assets before they are published as a new versioned release.

However, this operator cannot guess the volume of the whole stream, and can be "surprised" by rapid changes of the volume. This can lead to a volume that is too low, too high, oscillates. In some cases, dynamic normalization also creates saturation. To tweak the normalization, several parameters are available. These are listed and explained in the [reference](reference.html) and also visible by executing `liquidsoap -h normalize`. However, if the stream you want to normalize consist of audio files, using the replay gain technology might be a better choice. ## Replay gain [ReplayGain](https://en.wikipedia.org/wiki/ReplayGain) is a proposed standard that is (more or less) respected by many open-source tools. It provides a way to obtain an overall uniform perceived loudness over a track or a set of tracks. The computation of the loudness is based on how the human ear actually perceives each range of frequency. Having computed the average perceived loudness on a track or an album, it is easy to renormalize the tracks when playing, ensuring a comfortable, consistent listening experience. Because it is track-based, replay gain does not suffer from the typical problems of stream-based, dynamic approaches. Namely, these distort the initial audio, since they constantly adapt the amplification factor. Sometimes it oscillates too quickly in a weird audible way. Sometimes it does not adapt quickly enough, leading to under or over-amplified sections. ### Computing or retrieving replay gain information The first step in order to use replay gain is to fetch or compute the appropriate normalization level for a given file. Replay gain information can be found in various metadata fields depending on the audio format and the replay gain computation tool. Liquidsoap provides a script for extracting the replay gain value which requires the `ffmpeg` binary. There are two ways to use our replain gain script, one that works for _all_ files and one that can be enabled on a per-file basis, if you need finer grained control over replay gain. #### Using the replay gain metadata resolver The metadata solution is uniform: without changing anything, _all_ your files will have a new `replaygain_track_gain` metadata when the computation succeeded. However, keep in mind that this computation can be costly and will be done each time a remote file is downloaded to be prepared for streaming unless it already has the information pre-computed. For this reason, it is recommended to pre-compute replay gain information as much as possible, specially if you intent to stream large audio files. The replay gain metadata resolver is not enabled by default. You can do it by adding the following code to your script: ```liquidsoap enable_replaygain_metadata() ``` #### Using the `replaygain:` protocol The `replaygain:` protocol triggers replay gain retrieval or computation on a per-file bases. To use it, you prefix your request URIs with it. For instance, replacing `/path/to/file.mp3` with `replaygain:/path/to/file.mp3`. When resolving such a request, a call to our script will be issued, resulting in your file having the extra `replaygain_track_gain` metadata. Prepending `replaygain:` is easy if you are using a script behind some `request.dynamic.list` operator. If you are using the `playlist` operator, you can use its `prefix` parameter. Protocols can be chained, for instance: ``` annotate:foo="bar":replaygain:/path/to/file.mp3 ``` ### Applying replay gain information After fetching or computing the replay gain information, the next step is to use it to correct the source's volume. The `amplify()` operator is used for that. This operator can be made to behave according to a given metadata, here the `replaygain` metadata. This is done using the `override` parameter. For replay gain implementation, the `amplify` operator would typically be added immediately on top of the basic tracks source, before transitions or other audio processing operators. Typically: ```{.liquidsoap include="replaygain-metadata.liq" to="END"} ``` For convenience, we added the `replaygain` operator which performs the amplification on the right metadata so that this can further be simplified to ```{.liquidsoap include="replaygain-playlist.liq" to="END"} ``` ������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/request_sources.md�����������������������������������������������������0000664�0000000�0000000�00000007775�14773033502�0021710�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������Playing files is the most common way to build an audio stream. In liquidsoap, files are accessed through [requests](requests.html), which combine the retrieval of a possibly remote file, and its decoding. Liquidsoap provides several operators for playing requests: `single`, `playlist` and `playlist.safe`, `request.dynamic.list`, `request.queue` and `request.equeue`. In a few cases (`single` with a local file, or `playlist.safe`) a request operator will know that it can always get a ready request instantaneously. It will then be [infallible](sources.html). Otherwise, it will have a queue of requests ready to be played (local files with a valid content), and will feed this queue in the background. This process is described here. ## Common parameters Queued request sources maintain an _estimated remaining time_, and trigger a new request resolution when this remaining time goes below their `length` parameter. The estimation is based on the duration of files prepared in the queue, and the estimated remaining time in the currently playing file. Precise file durations being expensive to compute, they are not forced: if a duration is provided in the metadata it shall be used, otherwise the `default_length` is assumed. For example, with the default 10 seconds of wanted queue length, the operator will only prepare a new file 10 seconds before the end of the current one. Up to liquidsoap 0.9.1, the estimated remaining time in the current track was not taken into account. With this behavior, each request-based source would keep at least one song in queue, which was sometimes inconvenient. This behavior can be restored by passing `conservative=true`, which is useful in some cases: it helps to ensure that a song will be ready in case of skip; generally, it prepares things more in advance, which is good when resolution is long (_e.g._, heavily loaded server, remote files). ## Request.dynamic This source takes a custom function for creating its new requests. This function, of type `()->request`, can for example call an external program. To create the request, the function will have to use the `request.create` function which has type `(string,?indicators:[string])`. The first string is the initial URI of the request, which is resolved to get an audio file. The second argument can be used to directly specify the first row of URIs (see the page about [requests](requests.html) for more details), in which case the initial URI is just here for naming, and the resolving process will try your list of indicators one by one until a valid audio file is obtained. An example that takes the output of an external script as an URI to create a new request can be: ```liquidsoap def my_request_function() = # Get the first line of my external process result = list.hd(default="", process.read.lines("my_script my_params")) # Create and return a request using this result [request.create(result)] end # Create the source s = request.dynamic.list(my_request_function) ``` ## Queues Liquidsoap features two sources which provide request queues that can be directly manipulated by the user, via the server interface: `request.queue` and `request.equeue`. The former is a queued source where you can only push new requests, while the later can be edited. Both operators actually deal with two queues: _primary_ and _secondary_ queues. The secondary queue is user-controlled. The primary queue is the one that all queued request sources have, its behavior is the same as described above, and it cannot be changed in any way by the user. Requests added to the secondary queue sit there until the feeding process gets them and attempts to prepare them and put them in the primary queue. You can set how many requests will be in that primary queue by tweaking the common parameters of all queued request sources. The two sources are controlled via the [command server](advanced.html). They both feature commands for looking up the queues, queuing new requests, and the `equeue` operator also allows removal and exchange of requests in the secondary queue. ���liquidsoap-2.3.2/doc/content/requests.md������������������������������������������������������������0000664�0000000�0000000�00000006033�14773033502�0020312�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# An abstract notion of files: requests The request is an abstract notion of file which can be conveniently used for defining powerful sources. A request can denote a local file, a remote file, or even a dynamically generated file. They are resolved to a local file thanks to a set of _protocols_. Then, audio requests are transparently decoded thanks to a set of audio and metadata _formats_. The systematic use of requests to access files allows you to use remote URIs instead of local paths everywhere. It is perfectly OK to create a playlist for a remote list containing remote URIs: ` playlist("http://my/friends/playlist.pls")` . ## The resolution process The nice thing about resolution is that it is recursive and supports backtracking. An URI can be changed into a list of new ones, which are in turn resolved. The process succeeds if some valid local file appears at some point. If it doesn't succeed on one branch then it goes back to another branch. A typical complex resolution would be: - `bubble:artist="bodom"` _ `ftp://no/where` _ `Error` - `ftp://some/valid.ogg` \* `/tmp/success.ogg` On top of that, metadata is extracted at every step in the branch. Usually, only the final local file yields interesting metadata (artist,album,...). But metadata can also be the nickname of the user who requested the song, set using the `annotate` protocol. At the end of the resolution process, in case of a media request, liquidsoap checks that the file is decodable, _i.e._, there should be a valid decoder for it. Each request gets assigned a request identifier (RID) which is used by various sources to identify which request(s) they are using. Knowing this number, you can monitor a request, even after it's been destroyed (see setting `request.grace_time`). Two [server](server.html) commands are available: `request.trace` shows a log of the resolution process and `request.metadata` shows the current request metadata. In addition, server commands are available to obtain the list of all requests, alive requests, currently resolving requests and currently playing requests (respectively `request.all`, `request.alive`, `request.resolving`, `request.on_air`). ## Currently supported protocols - HTTP, HTTPS, FTP thanks to curl - SAY for speech synthesis (requires festival): `say:I am a robot` resolves to the WAV file resulting from the synthesis. - TIME for speech synthesis of the current time: ` time: It is exactly $(time), and you're still listening.` - ANNOTATE for manually setting metadata, typically used in ` annotate:nick="alice",message="for bob":/some/track/uri` The extra metadata can then be synthesized in the audio stream, or merged into the standard metadata fields, or used on a rich web interface... It is also possible to add a new protocol from the script, as it is done with [Beets](beets.html) for getting songs from a database query. ## Currently supported formats - MPEG-1 Layer II (MP2) and Layer III (MP3) through libmad and `ocaml-mad` - Ogg Vorbis through libvorbis and `ocaml-vorbis` - WAV - AAC - and much more through external decoders! �����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/rolling-release.md�����������������������������������������������������0000664�0000000�0000000�00000001220�14773033502�0021514�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������This release provides liquidsoap assets before they are published as a new versioned release.

For example you can store your passwords by defined the variable `xxx` in `secret.liq`, and then refer to that variable in your main script `main.liq`. You would then run `liquidsoap secret.liq main.liq`. If you ever need to communicate `main.liq` there won't be any risk of divulgating your password. ## The pervasive script library In fact, liquidsoap also implicitly loads scripts before those that you specify on the command-line. These scripts are meant to contain standard utilities. Liquidsoap finds them in `LIBDIR/liquidsoap/VERSION` where `LIBDIR` depends on your configuration (it is typically `/usr/local/lib` or `/usr/lib`) and `VERSION` is the version of liquidsoap (_e.g._ `0.3.8` or `svn`). Currently, liquidsoap loads `stdlib.liq` from the library directory, and this file includes some others. You can add your personal standard library in that directory if you find it useful. ���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/seek.md����������������������������������������������������������������0000664�0000000�0000000�00000003606�14773033502�0017371�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Seeking in liquidsoap Starting with Liquidsoap `1.0.0-beta2`, it is now possible to seek within sources! Not all sources support seeking though: currently, they are mostly file-based sources such as `request.queue`, `playlist`, `request.dynamic.list` etc.. The basic function to seek within a source is `source.seek`. It has the following type: ``` (source('a),float)->float ``` The parameters are: - The source to seek. - The duration in seconds to seek from current position. The function returns the duration actually seeked. Please note that seeking is done to a position relative to the _current_ position. For instance, `source.seek(s,3.)` will seek 3 seconds forward in source `s` and `source.seek(s,(-4.))` will seek 4 seconds backward. Since seeking is currently only supported by request-based sources, it is recommended to hook the function as close as possible to the original source. Here is an example that implements a server/telnet seek function: ```{.liquidsoap include="seek-telnet.liq"} ``` ## Cue points File-based sources support cue-points to cut the beginning and end of tracks The values of cue-in and cue-out points are given in absolute position through the source's metadata. For instance, the following source will cue-in at 10 seconds and cue-out at 45 seconds on all its tracks: ```liquidsoap s = playlist(prefix="annotate:liq_cue_in=\"10.\",liq_cue_out=\"45\":", "/path/to/music") ``` As in the above example, you may use the `annotate` protocol to pass custom cue points along with the files passed to Liquidsoap. This is particularly useful in combination with `request.dynamic` as an external script can build-up the appropriate URI, including cue-points, based on information from your own scheduling back-end. Alternatively, you may use `metadata.map` to add those metadata. The operator `metadata.map` supports seeking and passes it to its underlying source. ��������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/server.md��������������������������������������������������������������0000664�0000000�0000000�00000020751�14773033502�0017750�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Interaction with the server Liquidsoap starts with one or several scripts as its configuration, and then streams forever if everything goes well. Once started, you can still interact with it by means of the _server_. The server allows you to run commands. Some are general and always available, some belong to a specific operator. For example the `request.queue()` instances register commands to enqueue new requests, the outputs register commands to start or stop the outputting, display the last ten metadata chunks, etc. The protocol of the server is a simple human-readable one. Currently it does not have any kind of authentication and permissions. It is currently available via two media: TCP and Unix sockets. The TCP socket provides a simple telnet-like interface, available only on the local host by default. The Unix socket interface (_cf._ the `server.socket` setting) is through some sort of virtual file. This is more constraining, which allows one to restrict the use of the socket to some privileged users. You can find more details on how to configure the server in the [documentation](help.html#settings) of the settings key `server`, in particular `server.telnet` for the TCP interface and `server.socket` for the Unix interface. Liquidsoap also embeds some [documentation](help.html#server) about the available server commands. ### Using telnet Now, we shall simply enable the Telnet interface to the server, by setting `settings.server.telnet := true` or simply passing the `-t` option on the command-line. In a [complete case analysis](complete_case.html) we set up a `request.queue()` instance to play user requests. It had the identifier `"queue"`. We are now going to interact via the server to push requests into that queue: ``` dbaelde@selassie:~$ telnet localhost 1234 Trying 127.0.0.1... Connected to localhost.localdomain. Escape character is '^]'. queue.push /path/to/some/file.ogg 5 END request.metadata 5 [...] END queue.push http://remote/audio.ogg 6 END request.trace 6 [...see if the download started/succeeded...] END exit ``` Of course, the server isn't very user-friendly. But it is easy to write scripts to interact with Liquidsoap in that way, to implement a website or an IRC interface to your radio. However, this sort of tool is often bound to a specific usage, so we have not released any of ours. ### Web interface Another simple way to test the telnet server consists in using the ```liquidsoap server.harbor() ``` server.harbor api: https://www.liquidsoap.info/doc-2.0.0/reference-extras.html#server.harbor command which will start a web interface accessible at <http://localhost:8000/telnet> providing an emulation of a telnet. ## Interactive variables Sometimes it is useful to control a variable using telnet. A simple way to achieve this is to use the `interactive.float` function. For instance, in order to dynamically the volume of a source: ```liquidsoap # Register a telnet variable named volume with 1 as initial value v = interactive.float("volume", 1.) # Change the volume accordingly source = amplify(v, source) ``` The first line registers the variable volume on the telnet. Its value can be changed using the telnet command ```liquidsoap var.set volume = 0.5 ``` and it can be retrieved using ```liquidsoap var.get volume ``` Similarly, we can switch between two tracks using `interactive.bool` and `switch` as follows: ```liquidsoap # Activate the telnet server settings.server.telnet := true # The two sources s1 = playlist("~/Music") s2 = sine() # Create an interactive boolean b = interactive.bool("button", true) # Switch between the tracks depending on the boolean s = switch(track_sensitive=false,[(b,s1), ({true},s2)]) # Output the result output.pulseaudio(s) ``` By default the source s1 is played. To switch to s2, you can connect on the telnet server and type `var.set button = false`. ### Web interface A nice web interface can be obtained by running ```liquidsoap interactive.harbor() ``` interactive.harbor api: https://www.liquidsoap.info/doc-2.0.0/reference.html#interactive.harbor after all interactive variables have been defined. This will start a web server accessible at <http://localhost:8000/interactive> on which you can easily change the values for the interactive variables. ### Persistency By default, interactive variables are not _persistent_, which means that their values are lost if you restart the script. This can be changed by running the command ```liquidsoap interactive.persistent("vars.json") ``` after all the interactive variables have been defined. This will store the values of all the interactive variables in the file `vars.json` (in JSON format) whenever you modify them, and reload them next time your run your script. This can be very handy for setting parameters for sound effects for instance. ## Securing the server The command server provided by liquidsoap is very convenient for manipulating a running instance of Liquidsoap. However, no authentication mechanism is provided. The telnet server has no authentication and listens by default on the localhost (`127.0.0.1`) network interface, which means that it is accessible to any logged user on the machine. Many users have expressed interest into setting up a secured access to the command server, using for instance user and password information. While we understand and share this need, we do not believe this is a task that lies into Liquidsoap's scope. An authentication mechanism is not something that should be implemented naively. Being SSH, HTTP login or any other mechanism, all these methods have been, at some point, exposed to security issues. Thus, implementing our own secure access would require a constant care about possible security issues. Rather than doing our own home-made secure access, we believe that our users should be able to define their own secure access to the command server, taking advantage of a mainstream authentication mechanism, for instance HTTP or SSH login. In order to give an example of this approach, we show here how to create a SSH access to the command server: we create a SSH user that, when logging through SSH, has only access to the command server. First, we enable the unix socket for the command server in Liquidsoap: ```liquidsoap settings.server.socket := true settings.server.socket.path := "/path/to/socket" ``` When started, liquidsoap will create a socket file `/path/to/socket` that can be used to interact with the command server. For instance, if your user has read and write rights on the socket file, you can do ```liquidsoap socat /path/to/socket - ``` The interface is then exactly the same has for the telnet server. We define now a new ``shell''. This shell is in fact the invocation of the socat command. Thus, we create a `/usr/local/bin/liq_shell` file with the following content: ```bash #!/bin/sh # We test if the file is a socket, readable and writable. if [ -S /path/to/socket ] && [ -w /path/to/socket ] && \ [ -r /path/to/socket ]; then socat /path/to/socket - else # If not, we exit.. exit 1 fi ``` We set this file as executable, and we add it in the list of shells in `/etc/shells`. Now, we create a user with the `liq_shell` as its shell: ``` adduser --shell /usr/local/bin/liq_shell liq-user ``` You also need to make sure that `liq-user` has read and write rights on the socket file. Finally, when logging through ssh with `liq-user`, we get: ``` 11:27 toots@leonard % ssh liq-user@localhost liq-user@localhost's password: Linux leonard 2.6.32-4-amd64 #1 SMP Mon Apr 5 21:14:10 UTC 2010 x86_64 The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright.

Last login: Tue Oct 5 11:26:52 2010 from localhost help Available commands: (...) | exit | help [<command>] | list | quit | request.alive | request.all | request.metadata <rid> | request.on_air | request.resolving | request.trace <rid> | uptime | var.get <variable> | var.list | var.set <variable> = <value> | version Type "help <command>" for more information. END exit Bye! END Connection to localhost closed. ``` This is an example of how you can use an existing secure access to secure the access to liquidsoap's command server. This way, you make sure that you are using a mainstream secure application, here SSH. This example may be adapted similarly to use an online HTTP login mechanism, which is probably the most comment type of mechanism intended for the command line server. �����������������������liquidsoap-2.3.2/doc/content/shoutcast.md�����������������������������������������������������������0000664�0000000�0000000�00000002565�14773033502�0020462�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Streaming to Shoutcast Although Liquidsoap is primarily aimed at streaming to Icecast servers (that provide much more features than Shoutcast), it is also able to stream to Shoutcast. ## Shoutcast output Shoutcast server accept streams encoded with the MP3 or AAC/AAC+ codec. You to compile Liquidsoap with `lame` support, so it can encode in MP3. Liquidsoap also has support for AAC+ encoding using FDK-AAC or using an [external encoder](external_encoders.html). The recommended format is MP3. Shoutcast output are done using the `output.shoutcast` operator with the appropriate parameters. An example is: ```{.liquidsoap include="shoutcast.liq"} ``` As usual, `liquidsoap -h output.shoutcast` gives you the full list of options for this operator. ## Shoutcast as relay A side note for those of you who feel they ``need'' to use Shoutcast for non-technical reasons (such as their stream directory service...): you can still benefit from Icecast's power by streaming to an Icecast server, and then relaying it through a shoutcast server. In order to do that, you have to alias the root mountpoint ("`/`") to your MP3 mountpoint in your icecast server configuration, like this: ``` <alias source="/" dest="/mystream.mp3" /> ``` Be careful that icecast often aliases the status page (`/status.xsl`) with the `/`. In this case, comment out the status page alias before inserting yours. �������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/sources.md�������������������������������������������������������������0000664�0000000�0000000�00000014647�14773033502�0020134�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Sources Using liquidsoap is about writing a script describing how to build what you want. It is about building a stream using elementary streams and stream combinators, etc. Actually, it's a bit more than streams, we call them _sources_. A source is a stream with metadata and track annotations. It is discretized as a stream of fixed-length buffers of media samples, the frames. Every frame may have metadata inserted at any point, independently of track boundaries. At every instant, a source can be asked to fill a frame of data. The liquidsoap API provides plenty of functions for building sources. Some of those functions build elementary sources from scratch, others are operators that combine sources into more complex ones. An important class of sources is that of _active sources_, they are the sources that actively trigger the computation of your stream. Typically, active sources are built from output functions, because outputting a stream is the only reason why you want to compute it. All sources, operators and outputs are listed in the [scripting API reference](reference.html). ## How does it work? To clarify the picture let's study in more details an example: ```liquidsoap radio = output.icecast( %vorbis,mount="test.ogg", random( [ jingle , fallback([ playlist1,playlist2,playlist3 ]) ])) ``` At every cycle of the [clock](clocks.html), the output asks the `random` node for data, until it gets a full frame of raw audio. Then, it encodes the frame and sends it to the Icecast server. Suppose `random` has chosen the `fallback` node, and that only `playlist2` is available, and thus played. At every cycle, the buffer is passed from `random` to `fallback` and then to `playlist2` which fills it, returns it to `fallback` which returns it to `random` which returns it to the output. At some point, `playlist2` ends a track. The fallback detects that on the returned buffer, and selects a new child for the next filling, depending on who's available. But it doesn't change the buffer, and returns it to `random`, which also (randomly) selects a new child at this point, before returning the buffer to the output. On next filling, the route of the frame can be different. Note that it is also possible to have the route changed inside a track, for example using the `track_sensitive` option of fallback, which is typically done for instant switches to live shows when they start. The important point here is that **all of the above steps are local**. Everything takes place between one operator and its immediate children source; operators do not see beyond that point. ## Fallibility By default, liquidsoap outputs are meant to emit a stream without discontinuing. Since this stream is provided by the source passed to the output operator, it is the source responsibility to never fail. Liquidsoap has a mechanism to verify this, which helps you think of all possible failures, and prevent them. Elementary sources are either _fallible_ or _infallible_, and this _liveness type_ is propagated through operators to finally compute the type of any source. For example, a `fallback` or `random` source is infallible if an only if at least one of its children is infallible, and a `switch` is infallible if and only if it has one infallible child guarded by the trivial predicate `{ true }`. On startup, each output checks the liveness type of its input source, and issues an error if it is fallible. The typical fix for such problems is to add one fallback to play a default file (`single()`) or a checked playlist (`playlist.safe()`) if the normal source fails. One can also use the `mksafe` operator that will insert silence during failures. If you do not care about failures, you can pass the parameter `fallible=true` to most outputs. In that case, the output will accept a fallible source, and stop whenever the source fails, to restart when it is ready to emit a stream again. ## Caching mode In some situations, a source must take care of the consistency of its output. If it is asked twice to fill buffers during the same cycle, it should fill them with the same data. Suppose for example that a playlist is used by two outputs, and that it gives the first frame to the first output, the second frame to the second output: it would give the third frame to the first output during the second cycle, and the output will have missed one frame. It is sometimes useful to keep this is mind to understand the behaviour of some complex scripts. The high-level picture is enough for users, more details follow for developers and curious readers. The sources detect if they need to remember (cache) their previous output in order to replay it. To do that, clients of the source must register in advance. If two clients have registered, then caching should be enabled. Actually that's a bit more complicated, because of transitions. Obviously the sources which use a transition involving some other source must register to it, because they may eventually use it. But a jingle used in two transitions by the same switching operator doesn't need caching. The solution involves two kinds of registering: _dynamic_ and _static activations_. Activations are associated with a path in the graph of sources' nesting. The dynamic activation is a pre-registration allowing a single real _static activation_ to come later, possibly in the middle of a cycle. Two static activations trigger caching. The other reason for enabling caching is when there is one static activation and one dynamic activation which doesn't come from a prefix of the static activation's path. It means that the dynamic activation can yield at any moment to a static activation and that the source will be used by two sources at the same time. ## Execution model In your script you define a bunch of sources interacting together. Each source belongs to a [clock](clocks.html), but clocks only have direct access to _active sources_, which are mostly outputs. At every cycle of the clock, active sources are animated: a chunk of stream (frame) is computed, and potentially outputted one way or another. This streaming task is the most important and shouldn't be disturbed. Thus, other tasks are done in auxiliary threads: file download, audio validity checking, http polling, playlist reloading... No blocking or expensive call should be done in streaming threads. Remote files are completely downloaded to a local temporary file before use by the root thread. It also means that you shouldn't access NFS or any kind of falsely local files. �����������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/split-cue.md�����������������������������������������������������������0000664�0000000�0000000�00000000567�14773033502�0020352�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Split and re-encode a CUE sheet. CUE sheets are sometimes distributed along with a single audio file containing a whole CD. Liquidsoap can parse CUE sheets as playlists and use them in your request-based sources. Here's for instance an example of a simple code to split a CUE sheet into several mp3 files with `id3v2` tags: ```{.liquidsoap include="split-cue.liq"} ``` �����������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/stereotool.md����������������������������������������������������������0000664�0000000�0000000�00000006114�14773033502�0020636�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Stereotool support Starting with version `2.2.0`, liquidsoap supports the shared library distributed by [Thimeo Audio Technology](https://www.thimeo.com/stereo-tool/) using the `stereotool` operator (and `track.audio.stereotool` for the low-level, track-specific equivalent). This feature is enabled in all release builds of liquidsoap starting with `rolling-release-v2.2.x` and should be enabled if you compile liquidsoap with the optional `ctypes-foreign` opam module installed. The operator can replace the use of the stereotool binary in your script and offers multiple benefits. In particular, it has a **very low latency** compared to using the binary and also operates synchronously. The operator should be quite easy to use. Here's an example: ```liquidsoap # Define a source s = ... # Apply stereotool to it: s = stereotool( library_file="/path/to/stereotool/shared/lib", license_key="my_license_key", preset="/path/to/preset/file", s ) ``` That's it! You can apply as many `stereotool` operators as you wish and at any stage in the script, thanks to its synchronous nature. However, a current limitation is that **the processed audio signal is slightly delayed**. This is because the operator has an internal processing buffer. We do plan on delaying metadata and track marks to match this latency but this has not yet been implemented and will probably have to wait for the `2.3.x` release cycle. This means that, until then, track switches and metadata updates might happen slightly earlier than the corresponding signal. We're talking about `50ms` to `100ms` earlier, though, so that might not be a super big deal. For the same reason, the source returned by `stereotool` is an _audio-only_ source. Otherwise, other concurrent tracks such as video and etc would be slightly out of sync. If you need to use the operator in this kind of situation, you might want to use a `ffmpeg` filter to e.g. adjust the video's PTS to match the audio delay. In such case, you can refer to the `latency` method that is available on the source returned by the operator which should indicate the delay to compensate from the processed audio signal. The operator's `preset` parameter has a companion `load_type` parameter that can optionally be used to only load a subset of the preset. You might refer to the upstream documentation if you need to use it. Lastly, `stereotool` is a **proprietary software**. While we actively promote open source, we also want to meet our users where they are and, for a lot of them, this means supporting the sound processing provided by the tool. However, to use it, you will need a license. Using the operator without the proper license will _not_ result in an error in your script but the audio signal might have spoken text and/or beeps added to it. Using the operator with an invalid license will be reported in the logs. You might also use the `valid_license` method available on the source returned by the operator, which returns `false` if the license is invalid. In this case, the `unlincensed_used_features` method returns a string indicating which unlicensed features are being used. ����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/stream_content.md������������������������������������������������������0000664�0000000�0000000�00000015775�14773033502�0021501�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Stream contents In liquidsoap, a stream may contain any number of audio, video and event MIDI channels (though this has not been tested in a while!). As part of the type checking of your script, liquidsoap checks that you make a consistent use of stream contents, and also guesses what kind of stream your script is intended to work on. As with other inferred parameters, you do not necessarily need to read about stream contents typing if you're still learning the ropes of liquidsoap, but you might eventually need to know a little about it. In liquidsoap script language, there are three sorts of objects that rely on stream types: sources, requests and encoding formats. A [source](sources.html) produces a stream, and it is important what kind of stream it produces when composing it with other sources. A [request](requests.html) is an abstract notion of file, often meant to be decoded, and it is useful to know into what kind of stream it is meant to be decoded. Finally, a [format](encoding_formats.html) describes how a stream should be encoded (_e.g._, before output in a file or via icecast), and the stream content is also useful here for the format to make sense. In this page, we explain how liquidsoap uses stream types to guess and check what you're doing. ## Content types Liquidsoap supports various type of content to be produced as the script runs. ### Internal content _internal_ content generally refers to content that the liquidsoap application can produce and manipulate. For audio, the default internal content is `pcm` floats using OCaml native 64-bits float array representations. This is the format that allows the fastest manipulation. For video, the default is a C in-memory arrays of plannar YUV420 data. For users concerned with memory consumption, we also support two additional audio formats, `pcm_s16` and `pcm_f32` using, resp., signed 16-bit integers and 32-bit floating point numbers. These formats may increase CPU usage, however, as we do need to convert back and forth when using them in audio manipulation operators such as `amplify`, `crossfade` and etc. See [this link](memory.html#audio-data-format) for more details. ### Opaque content Liquidsoap also supports content type that are opaque to the application, provided by the `ffmpeg` decoder. There are two: - FFmpeg raw frames, which are decoded plain FFmpeg frames - FFmpeg packets, also referred to as FFmpeg copy content. These are packets of encoded content These type of content are consumed by FFmpeg specific operators and it is possible to convert back and forth if you want to use them with our internal operators. However, their best use-case is to keep them as-is end-to-end to optimize for memory and/or CPU usage. See the [FFmpeg support](ffmpeg.html) doc for more information. ## Global parameters You might have noticed that our description of internal stream contents is missing some information, such as sample rate, video size, etc. Indeed, that information is not part of the stream types, which is local to each source/request/format, but global in liquidsoap. You can change it using the `frame.audio/video.*` settings, shown here with their default values: ```liquidsoap audio.samplerate := 44100 video.frame.width := 320 video.frame.height := 240 video.frame.rate := 25 ``` ## Checking stream contents Checking the consistency of use of stream contents is done as part of type checking. There is not so much to say here, except that you have to read type errors. We present a few examples. For example, if you try to send an ALSA input to a SDL input using `output.sdl(input.alsa())`, you'll get the following: ``` At line 1, char 22-23: this value has type source(audio=pcm('a)) but it should be a subtype of source(video=canvas) ``` It means that a source with a video channel was expected by the SDL output, but the ALSA output can only offer sources producing audio. ## Conversions get a type error on seemingly meaningful code, and you'll wonder how to fix it. Often, it suffices to perform a few explicit conversions. Consider another example involving the SDL output, where we also try to use AO to output the audio content of a video: ```liquidsoap s = single("file.mp4") # Output video here output.file( %ffmpeg(%video(codec="libx264"), "/path/to/video.flv", s ) # Output audio here output.file( %ffmpeg(%audio(codec="aac")) "/path/to/video.aac", s ) ``` This won't work because the first output expects a video-only stream while the second one expected an audio-only stream The solution is to split the stream in two, dropping the irrelevant content: ```liquidsoap s = single("file.mp4") # Output video here output.file( %ffmpeg(%video(codec="libx264"), "/path/to/video.flv", source.drop.audio(s) ) # Output audio here output.file( %ffmpeg(%audio(codec="aac")) "/path/to/video.aac", source.drop.video(s) ) ``` Another conversion is muxing. It is useful to add audio/video channels to a pure video/audio stream. For this, see `source.mux.video` and `source.mux.audio`. ## Type annotations You now have all the tools to write a correct script. But you might still be surprised by what stream content liquidsoap guesses you want to use. This is very important, because even if liquidsoap finds a type for which it accepts to run, it might not run as you intend: a different type might mean a different behavior (not the intended number of audio channels, no video, etc). Before reading on how liquidsoap performs this inference, you can already work your way to the intended type by using type annotations. For example, with `output.alsa(input.alsa())`, you'll see that liquidsoap decides that stereo audio should be used, and consequently the ALSA I/O will be initialized with two channels. If you want to use a different number of channels, for example mono, you can explicitly specify it using: ```liquidsoap output.alsa((input.alsa():source(audio=pcm(mono)))) ``` ## Guessing stream contents When all other methods fail, you might need to understand a little more how liquidsoap guesses what stream contents should be used for each source. First, liquidsoap guesses as much as possible (without making unnecessary assumption) from what's been given in the script. Usually, the outputs pretty much determine what sources should contain. A critical ingredient here is often the [encoding format](encoding_formats.html). For example, in ```liquidsoap output.icecast(%vorbis,mount="some.ogg",s) ``` `%vorbis` has type `format(audio=pcm(stereo))`, hence `s` should have type `source(audio=pcm(stereo))`. This works in more complex examples, when the types are guessed successively for several intermediate operators. After this first phase, it is possible that some contents are still undetermined. For example in `output.alsa(input.alsa())`, any number of audio channels could work, and nothing helps us determine what is intended. At this point, the default numbers of channels are used. They are given by the setting `frame.audio/video/midi.channels` (whose defaults are respectively `2`, `0` and `0`). In our example, stereo audio would be chosen. ���liquidsoap-2.3.2/doc/content/strings_encoding.md����������������������������������������������������0000664�0000000�0000000�00000002354�14773033502�0022000�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# Strings encoding Liquidsoap operates internally using the UTF-8 string encoding. Most strings inside the application are converted to UTF-8 whenever possible. Conversion is done using [camomile](https://github.com/ocaml-community/camomile) automatic string encoding detection. If the conversion fails, the string is kept as-is. The list of encodings used for automatic detection is set via [settings.charset.encodings](settings.html#list-of-encodings-to-try-for-automatic-encoding-detection.) There are some exceptions, however. For instance, filenames and paths are not converted: if your system expects paths to be in a different encoding than UTF-8 then we do need to keep strings representing files and paths in this encoding to prevent errors. In general, you are advised to set the string encoding to UTF-8 on all systems running liquidsoap scripts for consistency and clarity. However, if for some reasons you need to tweak string encoding, these settings can be of use: - `settings.log.recode` and `settings.log.recode.encoding`: set the first one to `true` and the second one to the string encoding you would like log entries to be converted into. - `settings.metadata.recode`: set to `false` to prevent metadata from being converted to UTF-8. ������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/video-static.md��������������������������������������������������������0000664�0000000�0000000�00000000674�14773033502�0021037�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������# A simple video script The other day, I wanted to prepare some videos of my favorite reggae and soul tunes for uploading them to YouTube. My goal was very simple: prepare a video with the music, and a static image. After briefly digging for a simple software to do that, which I could not find, I said ``hey, why not doing it with liquidsoap''? Well, that is fairly easy! Here is the code: ```{.liquidsoap include="video-static.liq"} ``` ��������������������������������������������������������������������liquidsoap-2.3.2/doc/content/video.md���������������������������������������������������������������0000664�0000000�0000000�00000020367�14773033502�0017553�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������--- header-includes: | \DeclareUnicodeCharacter{03C0}{$\pi$} --- Basically streaming videos does not change anything compared to streaming audio: you just have to use video files instead of sound files! For instance, if you want to stream a single file to an icecast server in ogg format (with theora and vorbis as codecs for audio and video) you can simply type: ```{.liquidsoap include="video-simple.liq"} ``` And of course you could have used a `playlist` instead of `single` to have multiple files, or used other [formats](encoding_formats.html) for the stream. In order to test a video stream, it is often convenient to use the `output.sdl` operator (or `output.graphics`) which will open a window and display the video stream inside. These can handle streams with video only, you can use the `drop_audio` operator to remove the sound part of a stream if needed. You should be expecting much higher resource needs (in cpu time in particular) for video than for audio. So, be prepared to hear the fan of your computer! The size of videos have a great impact on computations; if your machine cannot handle a stream (i.e. it's always catching up) you can try to encode to smaller videos for a start. ### Setting up frame size and positions We provide an abstract API to specify video frame sizes and positions that is independent from the actual rendered size. This way, you can define all your elements and have them being rendered at different frame size without having to change their placement or size values! This works by setting up a _virtual canvas_ that is larger than the _actual canvas_. You specify your positions, sizes etc. in terms of units for the larger canvas and they are translated automatically to values that apply for the actual canvas. We provide some default values. They are all `16:9` ratio using a virtual canvas of `10 000` pixels height: ```{.liquidsoap include="video-default-canvas.liq"} ``` The returned canvas is a record with the following methods: - `width`/`height`: size of the actual frame - `px`: define values in terms of virtual pixels - `vw`/`vh`: define values in terms of percentage (between `0.` and `1.`) of, resp., the actual frame width and height - `rem`: define values in terms of percentage (between `0.` and `1.`) of the default font size All the positioning methods are functions. For convenience, you can use the infix operator `@` to make things more readable. For instance, instead of writing `px(120)` to define a size of `120px`, you can write: `120 @ px`. These two notations are equivalent but the second one is more readable in this context. Here's an example of how to use this: ```{.liquidsoap include="video-canvas-example.liq"} ``` ### Encoding with FFmpeg The `%ffmpeg` encoder is the recommended encoder when working with video. Not only does it support a wide range of audio and video formats but it can also send and receive data to many different places, using `input.ffmpeg.` and `output.url`. On top of that, it also supports all the [FFmpeg filters](https://ffmpeg.org/ffmpeg-filters.html) and passing encoded data, if your script does not need re-encoding. The syntax for the encoder is detailed in the [encoders page](encoding_formats.html). Here are some examples: ```liquidsoap # AC3 audio and H264 video encapsulated in a MPEG-TS bitstream %ffmpeg(format="mpegts", %audio(codec="ac3",channel_coupling=0), %video(codec="libx264",b="2600k", "x264-params"="scenecut=0:open_gop=0:min-keyint=150:keyint=150", preset="ultrafast")) # AAC audio and H264 video encapsulated in a mp4 file (to use with # `output.file` only, mp4 container cannot be streamed! %ffmpeg(format="mp4", %audio(codec="aac"), %video(codec="libx264",b="2600k")) # Ogg opus and theora encappsulated in an ogg bitstream %ffmpeg(format="ogg", %audio(codec="libopus"), %video(codec="libtheora")) # Ogg opus and VP8 video encapsulated in a webm bitstream %ffmpeg(format="webm", %audio(codec="libopus"), %video(codec="libvpx")) ``` ### Streaming with FFmpeg The main input to take advantage of FFmpeg is `input.ffmpeg`. It should be able to decode pretty much any url and file that the `ffmpeg` command-line can take as input. This is, in particular, how `input.rtmp` is defined. For outputting, one can use the regular outputs but some of them have special features when used with `%ffmpeg`: - `output.file` is able to properly close a file after it is done encoding it. This makes it possible to encode in formats that need a proper header after encoding is done, such as `mp4`. - `output.url` will only work with the `%ffmpeg` encoder. It delegates data output to FFmpeg and can support any url that the `ffmpeg` command-line supports. - `output.file.hls` and `output.harbor.hls` should only be used with `%ffmpeg`. The other encoders do work but `%ffmpeg` is the only encoder able to generate valid `MPEG-TS` and `MP4` data segments for the HLS specifications. ## Useful tips & tricks Video is a really exciting world where there are lots of cool stuff to do. ### Transitions Transitions at the beginning or at the end of video can be achieved using `video.fade.in` and `video.fade.out`. For instance, fading at the beginning of videos is done by ```{.liquidsoap include="video-transition.liq" from="BEGIN" to="END"} ``` ### Adding a logo You can add a logo (any image) using the `video.add_image` operator, as follows: ```{.liquidsoap include="video-logo.liq" from="BEGIN" to="END"} ``` ### Inputting from a webcam If your computer has a webcam, it can be used as a source thanks to the `input.v4l2` operator. For instance: ```{.liquidsoap include="video-webcam.liq"} ``` ### Video in video Suppose that you have two video sources `s` and `s2` and you want to display a small copy of `s2` on top of `s`. This can be achieved by ```{.liquidsoap include="video-in-video.liq" from="BEGIN" to="END"} ``` ### Scrolling text Adding scrolling text at the bottom of your video is as easy as ```{.liquidsoap include="video-text.liq"} ``` You might need to change the `font` parameter so that it matches a font file present on your system. ### Effects There are many of effects that you can use to add some fun to your videos: `video.greyscale`, `video.sepia`, `video.lomo`, etc. [Read the documentation](reference.html) to find out about them. If you have compiled Liquidsoap with [frei0r](http://www.piksel.org/frei0r/) support, and have installed frei0r plugins, they will be named `video.frei0r.*`. You can have a list of those supported on your installation as usual, using `liquidsoap --list-plugins`. ### Presenting weather forecast You can say that a specific color should be transparent using `video.transparent`. For instance, you can put yourself in front of a blue screen (whose RGB color should be around 0x0000ff) and replace the blue screen by an image of the weather using ```{.liquidsoap include="video-weather.liq" to="END"} ``` ## Detailed examples ### The anonymizer Let's design an ``anonymizer'' effect: I want to blur my face and change my voice so that nobody will recognise me in the street after seeing the youtube video. Here is what we are going to achieve: <center><iframe width="560" height="315" src="//www.youtube.com/embed/E7Fb0wV3h5Q" frameborder="0" allowfullscreen></iframe></center>This video was produced thanks to the following script: ```{.liquidsoap include="video-anonymizer.liq"} ``` ### Controlling with OSC In this example we are going to use OSC integration in order to modify the parameters in realtime. There are many OSC clients around, for instance I used [TouchOSC](http://hexler.net/software/touchosc) : <center><iframe width="560" height="315" src="//www.youtube.com/embed/EX1PTjiuuXY" frameborder="0" allowfullscreen></iframe></center>Here is how the video was made: ```{.liquidsoap content="video-osc.liq"} ``` ### Blue screen You want to show yourself in front of a video of a bunny, as in <center><iframe width="640" height="360" src="//www.youtube.com/embed/zHikXRNMQu4?feature=player_detailpage" frameborder="0" allowfullscreen></iframe></center>The idea is to film yourself in front of a blue screen, make this blue screen transparent and put the resulting video in front of the bunny video (actually, I don't have a blue screen at home, only a white wall but it still kinda works). ```{.liquidsoap include="video-bluescreen.liq"} ``` �������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/content/xml.md�����������������������������������������������������������������0000664�0000000�0000000�00000010672�14773033502�0017243�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������## Importing/exporting XML values Support for XML parsing and rendering was first added in liquidsoap `2.3.1`. You can parse XML strings using a decorator and type annotation. There are two different representations of XML you can use. ### Record access representation This is the easiest representation. It is intended for quick access to parsed value via record and tuples. Here's an example: ```liquidsoap s = '<bla param="1" bla="true"> <foo opt="12.3">gni</foo> <bar /> <bar>bla</bar> <blo>1.23</blo> <blu>false</blu> <ble>123</ble> </bla>' let xml.parse (x : { bla: { foo: string.{ xml_params: {opt: float} }, bar: (unit * string), blo: float, blu: bool, ble: int, xml_params: { bla: bool } } } ) = s print("The value for ble is: #{x.bla.ble}") ``` Things to note: - The basic mappings are: `<tag name> -> <tag content>` - Tag content maps tag parameters to a `xml_params` method. - When multiple tags are present, their values are collected as tuple (`bar` tag in the example) - When a tag contains a single ground value (`string`, `bool`, `float` or `integer`), the mapping is from tag name to the corresponding value, with xml attributes attached as methods - Tag parameters can be converted to ground values and omitted. The parsing is driven by the type annotation and is intended to be permissive. For instance, this will work: ```liquidsoaop s = '<bla>foo</bla>' # Here, `foo` is omitted. let xml.parse (x: { bla: unit }) = s # x contains: { bla = () } # Here, `foo` is made optional let xml.parse (x: { bla: string? }) = s # x contains: { bla = "foo" } ``` ### Formal representation Because XML format can result in complex values, the parser can also use a generic representation. Here's an example: ```liquidsoap s = '<bla param="1" bla="true"> <foo opt="12.3">gni</foo> <bar /> <bar>bla</bar> <blo>1.23</blo> <blu>false</blu> <ble>123</ble> </bla>' let xml.parse (x : ( string * { xml_params: [(string * string)], xml_children: [ ( string * { xml_params: [(string * string)], xml_children: [(string * {xml_text: string})] } ) ] } ) ) = s # x contains: ( "bla", { xml_children= [ ( "foo", { xml_children=[("xml_text", {xml_text="gni"})], xml_params=[("opt", "12.3")] } ), ("bar", {xml_children=[], xml_params=[]}), ( "bar", { xml_children=[("xml_text", {xml_text="bla"})], xml_params=[("option", "aab")] } ), ( "blo", {xml_children=[("xml_text", {xml_text="1.23"})], xml_params=[]} ), ( "blu", {xml_children=[("xml_text", {xml_text="false"})], xml_params=[]} ), ( "ble", {xml_children=[("xml_text", {xml_text="123"})], xml_params=[]} ) ], xml_params=[("param", "1"), ("bla", "true")] } ) ``` This representation is much less convenient to manipulate but allows an exact representation of all XML values. Things to note: - XML nodes are represented by a pair of the form: `(<tag name>, <tag properties>)` - `<tag properties>` is a record containing the following methods: - `xml_params`, represented as a list of pairs `(string * string)` - `xml_children`, containing a list of the XML node's children. Each entry in the list is a node in the formal XML representation. - `xml_text`, present when the node is a text node. In this case, `xml_params` and `xm_children` are empty. - By convention, text nodes are labelled `xml_text` and are of the form: `{ xml_text: "node content" }` ### Rendering XML values XML values can be converted back to strings using `xml.stringify`. Both the formal and record-access form can be rendered back into XML strings however, with the record-access representations, if a node has multiple children with the same tag, the conversion to XML string will fail. More generally, if the values you want to convert to XML strings are complex, for instance if they use several times the same tag as child node or if the order of child nodes matters, we recommend using the formal representation to make sure that children ordering is properly preserved. This is because record methods are not ordered in the language so we make no guarantee that the child nodes they represent be rendered in a specific order. ����������������������������������������������������������������������liquidsoap-2.3.2/doc/content/yaml.md����������������������������������������������������������������0000664�0000000�0000000�00000001256�14773033502�0017403�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������## Importing/exporting YAML values Support for YAML parsing and rendering was first added in liquidsoap `2.2.0`. This support follows the same pattern as [JSON parsing/rendering](json.html) but using yaml-based syntax, i.e.: ```liquidsoap let yaml.parse ({ name, version, scripts, } : { name: string, version: string, scripts: { test: string? }? }) = file.contents("/path/to/file.yaml") ``` and ```liquidsoap r = {artist = "Bla", title = "Blo"} print(yaml.stringify(r)) ``` The only major difference being that, in YAML, all numbers are parsed and rendered as _floats_. Please refer to the [JSON parsing and rendering](json.html) documentation for more details. ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������liquidsoap-2.3.2/doc/dune���������������������������������������������������������������������������0000664�0000000�0000000�00000001615�14773033502�0015322�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������; Regenerate using dune build @gendune --auto-promote (include dune.inc) (rule (alias dummytest) (package liquidsoap) (action (run %{bin:liquidsoap} --version))) (executable (name gen_dune) (preprocess (pps ppx_string)) (libraries re liquidsoap_build_tools) (modules gen_dune)) (executable (name subst_md) (libraries re liquidsoap_lang) (modules subst_md)) (rule (alias gendune) (target dune.inc.gen) (deps (source_tree ../src/libs) (source_tree .))

You'll find the "Writing a Kate Highlighting XML File HOWTO" at http://kate.kde.org/doc/hlhowto.php This format is identified using the SYSTEM identifier SYSTEM "language.dtd" Files using this format should include a DOCTYPE declaration like this: <!DOCTYPE language SYSTEM "language.dtd"> You can validate your syntax files using checkXML from the development package of kdelibs: checkXML yourSyntax.xml If you see any 'validity error' lines, you should fix them. If you get a lot of 'No template matches' lines, everything's just fine. You've produced a valid syntax file! It's also possible to use the (much faster) xmllint which comes with the GNOME (oops:-) XML Library libxml2: xmllint - -dtdvalid language.dtd yourSyntax.xml (don't use a space between the two - That's just because XML comments don't allow that:-( To use your syntax file, copy it to .kde/share/apps/katepart/syntax/ in your home directory. You have to open a new instance of kwrite/kate to use the new syntax file.

It is very flexible, making simple things simple but giving a lot of control for advanced uses. Liquidsoap supports audio, video and MIDI streams, and a wide range of input/output operators including Icecast and various soundcard APIs. It can perform a broad range of signal processing, combine streams in various ways, support custom transitions, generate sound procedurally... and all this can be assembled as you wish. Input files can be accessed remotely, or even be synthesized on the fly using external scripts such as speech synthesis. Finally, interaction with a running liquidsoap instance is possible via telnet or socket. Liquidsoap scripts passed on the command line will be evaluated: they shall be used to define the streaming system to be ran. It is possible to pass multiple scripts; they will all be ran successively, and definitions from one script can be used in subsequent ones. A script will be read from standard input if `-` is given as script filename. Information about scripting liquidsoap is available on our website: [http://liquidsoap.info/](http://liquidsoap.info/). If the parameter is not a file it will be treated as an expression which will be executed. It is a convenient way to test simple one-line scripts. When running only one-liners, the default is to log messages directly on stdout rather than to a file. # OPTIONS \- : Read script from standard input. \-- : Stop parsing the command-line and pass subsequent items to the script. \--debug : Print debugging log messages. \--dynamic-plugins-dir _path_ : Directory where to look for plugins. \--errors-as-warnings : Issue warnings instead of fatal errors for unused variables and ignored expressions. If you are not sure about it, it is better to not use it. \--interactive : Start an interactive interpreter. \--list-plugins : List all plugins (builtin scripting values, supported formats and protocols). \--list-plugins-xml : List all plugins (builtin scripting values, supported formats and protocols), output as XML. \--no-stdlib : Do not load pervasive script libraries. \--version : Display Liquidsoap's version. \--build-config : Display Liquidsoap's build config. -c, \--check : Check and evaluate scripts but do not perform any streaming. -cl, \--check-lib : Like \--check but treats all scripts and expressions as libraries, so that unused toplevel variables are not reported. -d, \--daemon : Run in daemon mode. -f, \--force-start : For advanced dynamic uses: force liquidsoap to start even when no active source is initially defined. -h _plugin_ : Print the description of a plugin, eg. a builtin scripting function. -i : Display inferred types. -p, --parse-only : Parse scripts but do not type-check and run them. -q, \--quiet : Do not print log messages on standard output. -r _filename_ : Process a request. -T, \--disable-telnet : Disable the telnet server. -U, \--disable-unix-socket : Disable the unix socket. -t, \--enable-telnet : Enable the telnet server. -u, \--enable-unix-socket : Enable the unix socket. -v, \--verbose : Print log messages on standard output. \--list-settings : Show all settings with their documentation. -help, \--help Display this list of options # SEE ALSO Our website [http://liquidsoap.info/](http://liquidsoap.info/) and the

Text in ordinary quotes is _never_ interpreted that way and highlighted just as a string. - There are quite a bit "special cases". That's because many keywords are not strictly they are keywords in some contexts and ordinary identifiers in others. Only some of such cases are handled; you still can get some of your identifiers highlighted wrong way. - Function names deliberately are not highlighted. There is no way to tell function call from other constructs, hence we can't highlight _all_ function names.

Things to consider: - FFmpeg filters are using a push paradigm, pushing from the sources down to the outputs - Liquidsoap uses a pull paradigm, pulling data from the outputs. - FFmpeg filters inputs need to know the exact content of the data sent to them before being initialized, which is only known in the worst case when receiving the first frame. Therefore, the intended implementation is to: -> Consider ffmpeg filter graphs as a single operator with N inputs and M outputs (audio/video) with inputs being any source converted to a ffmpeg graph input, even if not used, for simplification. -> The outputs are placed in their clock which controls a child clock containing the inputs. -> The graph initialization is suspended until its initialization conditions are met. -> When all the inputs have been initialized and are ready (call to `#is_ready`), the graph is considered ready and its output can start requesting content. This is captured by the call to `is_ready` below. -> When requesting content, the outputs can tick the input clock as many time as needed to generate output data. We expect more or less real time with perhaps an accordion pattern between input and output so we do not look at latency control like we do for crossfades. -> When receiving its first frame, the liquidsoap input will then initialize the corresponding ffmpeg graph input with full format info. -> When all inputs have been initialized, which is know by checking if all of the graph's lazy values for input pads have been forced (executed), the whole graph is initialized, outputs connected and data can start to flow! This is captured by the call to `initialized` below. This is contingent to the inputs being checked for `#is_ready` and the outputs only pulling when _all_ inputs are available, to avoid running into endless pulling loops. *) let ffmpeg_filter_audio = Lang.add_module ~base:ffmpeg_filter "audio" let ffmpeg_filter_video = Lang.add_module ~base:ffmpeg_filter "video" let log = Log.make ["ffmpeg"; "filter"] type 'a input = 'a Avfilter.input type 'a output = 'a Avfilter.output type 'a setter = 'a -> unit type 'a entries = (string, 'a setter) Hashtbl.t type inputs = ([ `Audio ] input entries, [ `Video ] input entries) Avfilter.av type outputs = ([ `Audio ] output entries, [ `Video ] output entries) Avfilter.av type graph = { mutable config : Avfilter.config option; mutable failed : bool; input_inits : (unit -> bool) Queue.t; graph_inputs : Source.source Queue.t; graph_outputs : Source.source Queue.t; init : unit Lazy.t Queue.t; entries : (inputs, outputs) Avfilter.io; } let init_graph graph = if Queue.fold graph.input_inits (fun v b -> b && v ()) true then ( try Queue.iter graph.init Lazy.force with exn -> let bt = Printexc.get_raw_backtrace () in graph.failed <- true; Printexc.raise_with_backtrace exn bt) let initialized graph = Queue.fold graph.init (fun q cur -> cur && Lazy.is_val q) true let is_ready graph = (match (initialized graph, Queue.peek_opt graph.graph_inputs) with | false, Some s -> Clock.tick s#clock | _ -> ()); (not graph.failed) && Queue.fold graph.graph_inputs (fun (s : Source.source) cur -> cur && s#is_ready) true let pull graph = match Queue.peek_opt graph.graph_inputs with | Some s -> Clock.tick s#clock | None -> () let self_sync graph source = (Clock_base.self_sync ~source (Queue.elements graph.graph_inputs)) () module Graph = Value.MkCustom (struct type content = graph let name = "ffmpeg.filter.graph" let to_string _ = name let to_json ~pos _ = Lang.raise_error ~message:"Ffmpeg filter graph cannot be represented as json" ~pos "json" let compare = Stdlib.compare end) module Audio = Value.MkCustom (struct type content = [ `Input of ([ `Attached ], [ `Audio ], [ `Input ]) Avfilter.pad | `Output of ([ `Attached ], [ `Audio ], [ `Output ]) Avfilter.pad Lazy.t ] let name = "ffmpeg.filter.audio" let to_string _ = name let to_json ~pos _ = Lang.raise_error ~pos ~message:"Ffmpeg filter audio input cannot be represented as json" "json" let compare = Stdlib.compare end) module Video = Value.MkCustom (struct type content = [ `Input of ([ `Attached ], [ `Video ], [ `Input ]) Avfilter.pad | `Output of ([ `Attached ], [ `Video ], [ `Output ]) Avfilter.pad Lazy.t ] let name = "ffmpeg.filter.video" let to_string _ = name let to_json ~pos _ = Lang.raise_error ~pos ~message:"Ffmpeg filter video input cannot be represented as json" "json" let compare = Stdlib.compare end) let uniq_name = let names = Hashtbl.create 10 in let name_idx name = match Hashtbl.find_opt names name with | Some x -> Hashtbl.replace names name (x + 1); x | None -> Hashtbl.replace names name 1; 0 in fun name -> Printf.sprintf "%s_%d" name (name_idx name) exception No_value_for_option let mk_options options = Avutil.Options.( let mk_opt ~t ~to_string ~from_value name help { default; min; max; values } = let desc = let string_of_value (name, value) = Printf.sprintf "%s (%s)" (to_string value) name in let string_of_values values = String.concat ", " (List.map string_of_value values) in match (help, default, values) with | Some help, None, [] -> Some help | Some help, _, _ -> let values = if values = [] then None else Some (Printf.sprintf "possible values: %s" (string_of_values values)) in let default = Option.map (fun default -> Printf.sprintf "default: %s" (to_string default)) default in let l = List.fold_left (fun l -> function Some v -> v :: l | None -> l) [] [values; default] in Some (Printf.sprintf "%s.
