Normally, a MOV/MP4 file has all the metadata about all packets * stored in one location (written at the end of the file, it can be moved to the start for better playback by * adding faststart to the movflags, or using the qt-faststart tool). A fragmented file consists of a number of * fragments, where packets and metadata about these packets are stored together. Writing a fragmented file has * the advantage that the file is decodable even if the writing is interrupted (while a normal MOV/MP4 is undecodable * if it is not properly finished), and it requires less memory when writing very long files (since writing normal * MOV/MP4 files stores info about every single packet in memory until the file is closed). The downside is that it * is less compatible with other applications. * * Options * ------- * * Fragmentation is enabled by setting one of the AVOptions that define how to cut the file into fragments: * * -moov_size bytes * * Reserves space for the moov atom at the beginning of the file instead of placing the moov atom at the end. * If the space reserved is insufficient, muxing will fail. * * -movflags frag_keyframe * * Start a new fragment at each video keyframe. * * -frag_duration duration * * Create fragments that are duration microseconds long. * * -frag_size size * * Create fragments that contain up to size bytes of payload data. * * -movflags frag_custom * * Allow the caller to manually choose when to cut fragments, by calling av_write_frame(ctx, nullptr) to write a * fragment with the packets written so far. (This is only useful with other applications integrating libavformat, * not from ffmpeg.) * * -min_frag_duration duration * * Don’t create fragments that are shorter than duration microseconds long. * * If more than one condition is specified, fragments are cut when one of the specified conditions is fulfilled. * The exception to this is -min_frag_duration, which has to be fulfilled for any of the other conditions to apply. * * Additionally, the way the output file is written can be adjusted through a few other options: * * -movflags empty_moov * * Write an initial moov atom directly at the start of the file, without describing any samples in it. Generally, * an mdat/moov pair is written at the start of the file, as a normal MOV/MP4 file, containing only a short portion * of the file. With this option set, there is no initial mdat atom, and the moov atom only describes the tracks * but has a zero duration. * * This option is implicitly set when writing ismv (Smooth Streaming) files. * * -movflags separate_moof * * Write a separate moof (movie fragment) atom for each track. Normally, packets for all tracks are written in a * moof atom (which is slightly more efficient), but with this option set, the muxer writes one moof/mdat pair for * each track, making it easier to separate tracks. * * This option is implicitly set when writing ismv (Smooth Streaming) files. * * -movflags faststart * * Run a second pass moving the index (moov atom) to the beginning of the file. This operation can take a while, * and will not work in various situations such as fragmented output, thus it is not enabled by default. * * -movflags rtphint * * Add RTP hinting tracks to the output file. * * -movflags disable_chpl * * Disable Nero chapter markers (chpl atom). Normally, both Nero chapters and a QuickTime chapter track are written * to the file. With this option set, only the QuickTime chapter track will be written. Nero chapters can cause * failures when the file is reprocessed with certain tagging programs, like mp3Tag 2.61a and iTunes 11.3, most likely * other versions are affected as well. * * -movflags omit_tfhd_offset * * Do not write any absolute base_data_offset in tfhd atoms. This avoids tying fragments to absolute byte positions * in the file/streams. * * -movflags default_base_moof * * Similarly to the omit_tfhd_offset, this flag avoids writing the absolute base_data_offset field in tfhd atoms, but * does so by using the new default-base-is-moof flag instead. This flag is new from 14496-12:2012. This may make the * fragments easier to parse in certain circumstances (avoiding basing track fragment location calculations on the * implicit end of the previous track fragment). * * -write_tmcd * * Specify on to force writing a timecode track, off to disable it and auto to write a timecode track only for mov and * mp4 output (default). * * -movflags negative_cts_offsets * * Enables utilization of version 1 of the CTTS box, in which the CTS offsets can be negative. This enables the initial * sample to have DTS/CTS of zero, and reduces the need for edit lists for some cases such as video tracks with B-frames. * Additionally, eases conformance with the DASH-IF interoperability guidelines. * * Possible codec options: * * @code * // -profile:v baseline -level 3.0 * { "profile", "baseline", 0, 0 }, * { "level", "3.0", 0, 0 }, * * // -profile:v high -level 3.1 - REQUIRED FOR PLAYBACK UNDER WIN7 * { "profile", "high", 0, 0 }, * { "level", "3.1", 0, 0 }, * * // Set speed (changes profile!): utra/veryfast and zerolatency * { "preset", "ultrafast", 0, OPT_SW_ONLY }, * { "preset", "veryfast", 0, OPT_SW_ONLY }, * { "tune", "zerolatency", 0, OPT_SW_ONLY }, * @endcode * * Possible format options: * * @code * { "moov_size", "1000000", 0, OPT_ALL }, // bytes * { "movflags", "+frag_keyframe", 0, OPT_ALL }, * { "frag_duration", "1000000", 0, OPT_ALL }, // microseconds * { "frag_size", "100000", 0, OPT_ALL }, // bytes * { "min_frag_duration", "1000", 0, OPT_ALL }, // microseconds * { "movflags", "+empty_moov", 0, OPT_ALL }, * { "movflags", "+delay_moov", 0, OPT_ALL }, * { "movflags", "+separate_moof", 0, OPT_ALL }, * { "movflags", "+faststart", 0, OPT_ALL }, * { "movflags", "+rtphint", 0, OPT_ALL }, * { "movflags", "+disable_chpl", 0, OPT_ALL }, * { "movflags", "+omit_tfhd_offset", 0, OPT_ALL }, * { "movflags", "+default_base_moof", 0, OPT_ALL }, * { "write_tmcd", "on", 0, OPT_ALL }, // on, off or auto * { "movflags", "+negative_cts_offsets", 0, OPT_ALL }, * { "movflags", "+isml", 0, OPT_ALL }, * @endcode * * @ingroup ffmpegfs * * @author Norbert Schlia (nschlia@oblivion-software.de) * @copyright Copyright (C) 2017-2026 Norbert Schlia (nschlia@oblivion-software.de) */ // **************************************************************************************************************** // Profiles // **************************************************************************************************************** const FFmpeg_Profiles::PROFILE_LIST_VEC FFmpeg_Profiles::m_profile = { // **************************************************************************************************************** // MP4 Container // **************************************************************************************************************** { FILETYPE::MP4, PROFILE::DEFAULT, //! @brief No opimisations, just plain mp4.

Controlling Speed and Quality //! ============================= //! //! libvpx-vp9 has two main control knobs for speed and quality: //! //! Deadline / Quality //! //! -deadline can be set to realtime, good, or best. For legacy reasons, the option is also accessible with -quality in ffmpeg. //! //! good is the default and recommended for most applications. //! best is recommended if you have lots of time and want the best compression efficiency. //! realtime is recommended for live / fast encoding. //! //! CPU Utilization / Speed //! ======================= //! //! -cpu-used sets how efficient the compression will be. For legacy reasons, the option is also accessible with -speed in ffmpeg. //! //! When the deadline/quality parameter is good or best, values for -cpu-used can be set between 0 and 5. The default is 0. //! Using 1 or 2 will increase encoding speed at the expense of having some impact on quality and rate control accuracy. //! 4 or 5 will turn off rate distortion optimization, having even more of an impact on quality. //! //! When the deadline/quality is set to realtime, the encoder will try to hit a particular CPU utilization target, and encoding quality //! will depend on CPU speed and the complexity of the clip that you are encoding. See ​the vpx documentation for more info. In this case, //! the valid values for -cpu-used are between 0 and 15, where the CPU utilization target (in per cent) is calculated as //! (100*(16-cpu-used)/16)%. //! //! ******************************************************************************************************************* //! { FILETYPE::WEBM, PROFILE::WEBM_DEFAULT, //! //! @brief WebM codec options. //! { { "deadline", "realtime", 0, OPT_SW_ONLY }, { "cpu-used", "8", 0, OPT_SW_ONLY }, // ffmpeg -i -c:v libvpx-vp9 -pass 2 -b:v 1000K -threads 8 -speed 1 // -tile-columns 6 -frame-parallel 1 -auto-alt-ref 1 -lag-in-frames 25 // -c:a libopus -b:a 64k -f webm out.webm // Most of the current VP9 decoders use tile-based, multi-threaded decoding.

Old filter graphs are now released before reinitialisation and when closing the current output, preventing stale filter pointers and retained filter buffers. * Bugfix: Fixed HLS playback stopping unexpectedly, especially near the last HLS segment. * Bugfix: Improved HLS segment finalisation and state cleanup between segment transitions. * Bugfix: Improved packet/frame lifetime handling to avoid stale state during HLS playback. * Added a `make help` target to list the available build, test, installation, documentation and maintenance targets. * Added `./configure --enable-perftools` to build ffmpegfs with Google Perftools heap profiling support. * Bugfix: Fixed HLS playback for 10-bit UHD/HDR sources by converting H.264 HLS output to yuv420p/8-bit. This avoids unsupported H.264 High10 streams in browser-based players such as hls.js. * Added elapsed-time reporting to successful transcode completion messages, showing the total transcoding time in milliseconds. * Bugfix: Fixed a race condition in transcoder thread start-up which could allow the same cache entry to be transcoded more than once concurrently. * Consolidated transcoder completion logging so each worker now emits one clear final status message, including elapsed runtime for successful transcodes. * Bugfix: Fixed HLS cache recovery so stale segment metadata no longer leaves playback waiting indefinitely when the corresponding cache file is missing, empty, or otherwise unusable. * Improved HLS segment recovery by explicitly restarting the transcoder when a segment is marked as available but its cache file is missing, empty, or otherwise unusable. * Bugfix: Fixed HLS segment availability checks so an incomplete cache entry no longer makes segments appear available if those segments were never actually produced. * Added additional safeguards for stale decoder state to avoid leaving cache entries permanently marked as decoding when no active worker is available to repair them. * Bugfix: Ignored HLS seek requests that are too close to the beginning of a stream so transcoding starts at segment 1 instead of creating an avoidable partial cache set. * Added an HLS cache regression test that pre-populates the cache, re-reads all generated segments, and verifies that cached segment output remains stable across repeated reads. * Bugfix: Fixed HLS cache test log naming so wrapper scripts which already contain the "_hls" suffix no longer generate duplicate "_hls_hls" builtin log files. * Bugfix: Fixed distclean/distcheck failures caused by incorrectly named HLS test log files being left behind in the test build directory. * Refactored transcoder stream and output initialisation into smaller helper functions, keeping high-level setup flow easier to follow. * Improved AVCodecContext ownership handling during stream, output, and frame-set setup so partially failed initialisation paths no longer leak codec contexts. * Hardened output/cache setup with additional validation and null checks to avoid partially initialised stream state and clearer error handling on invalid setup conditions. * Improved duration metadata handling for stream-copy and album-art output so invalid or missing input timing information is no longer used. * Improved test cleanup by using explicit ffmpegfs-owned temporary directory names and guarded removal logic, avoiding stale anonymous /tmp directories after interrupted or parallel test runs. * Improved deinterlacing quality by replacing yadif with bwdif while keeping one output frame per input frame. This improves playback smoothness for interlaced sources without changing the output frame rate or requiring changes to timestamp, FPS, or HLS segment timing logic. Important changes in 2.18 (2026-04-10): * Feature: Added ALAC profile for iTunes (--desttype=ALAC --profile=ITUNES). Playback of the file will not commence until it is fully recoded; however, it can be played in iTunes. * Feature: Implemented a validation check for the combination of TYPE and PROFILE in --desttype=TYPE --profile=PROFILE. * Updated Dockerfile to include Fuse3 * Bugfix: Fix error with new FFmpeg API. "Option 'pix_fmts' is not a runtime option and so cannot be set after the object has been initialized" * Fixed deprecation: Replace avcodec_get_supported_config() * Fixed deprecation: Remove avcodec_close() * Fixed deprecation: Remove av_format_inject_global_side_data() * Fixed deprecation: Replace std::codecvt with iconv in read_file * Bugfix: reserve() only guarantees capacity, not size → Writing via .data() is undefined behaviour. Using resize() makes the memory usable. * As strerror() is not thread-safe, use strerror_r() where available. * strncpy likes to copy without NUL → terminate explicitly. * Bugfix: Issue #173: Fixed output directory no showing complete list of files under Debian 13. * Closes#1115015: Fix build with FFmpeg 8 (already applied in Debian via NMU) * Closes#1119414: Changed configure.ac and makefile.am to preserve the default build flags Important changes in 2.17 (2024-11-10): * Bugfix: Issue #164: Fixed incorrectly discarded HLS seek requests. * Bugfix: Wrong error message fixed when an invalid audio/video codec was selected. The message should rather say "unsupported codec" instead of talking about "sample format not supported.". * Bugfix: Issue #162: If not present, add time stamps to the copied streams. * Changed quality from 34 to 40 for hardware encoded video streams to create slightly smaller files. * Closes#1084487: Moved from the Fuse 2 to the Fuse 3 API. Important changes in 2.16 (2024-06-10): * Bugfix: Closes#1072412: Fix build with FFmpeg 7.0. write_packet() now with const buffer as of Libavformat 61+. * Fixed deprecation: 2014-05-18 - 68c0518 / fd05602 - lavc 55.63.100 / 55.52.0 - avcodec.h Add avcodec_free_context(). From now on it should be used for freeing AVCodecContext. * Fixed deprecation: 2023-05-15 - 7d1d61cc5f5 - lavc 60 - avcodec.h Depreate AVCodecContext.ticks_per_frame in favor of AVCodecContext.framerate (encoding) and AV_CODEC_PROP_FIELDS (decoding). Important changes in 2.15 (2024-02-03): * Bugfix: Issue #151: Fixed autocopy STRICT never triggers for video streams * Bugfix: Issue #153: The --include_extensions parameter now contains a description, which was previously missing from the manual and online help. * Issue #149: 2023-05-04 - xxxxxxxxxx - lavu 58.7.100 - frame.h Deprecate AVFrame.interlaced_frame, AVFrame.top_field_first, and AVFrame.key_frame. Add AV_FRAME_FLAG_INTERLACED, AV_FRAME_FLAG_TOP_FIELD_FIRST, and AV_FRAME_FLAG_KEY flags as replacement. * Issue #149: 2023-05-04 - xxxxxxxxxx - lavu 58.7.100 - frame.h Deprecate AVFrame.interlaced_frame, AVFrame.top_field_first, and AVFrame.key_frame. Add AV_FRAME_FLAG_INTERLACED, AV_FRAME_FLAG_TOP_FIELD_FIRST, and AV_FRAME_FLAG_KEY flags as replacement. * Issue #149: 2021-09-20 - dd846bc4a91 - lavc 59.8.100 - avcodec.h codec.h Deprecate AV_CODEC_FLAG_TRUNCATED and AV_CODEC_CAP_TRUNCATED, as they are redundant with parsers. * Issue #136: The CMake build files have been removed. Support was never more than experimental, and CMake lacks a good uninstall option. Will stick to automake system from now on. Important changes in 2.14 (2023-06-15): * Bugfix: Issue #141: Improved memory management by allocating several times the average size of allocations. This prevents obtaining tiny portions over and over again. Additionally, after the file is opened, grab the entire expected memory block rather than doing a tiny allocation initially, followed by a larger allocation. * Bugfix: Avoid race conditions that cause the inter-process semaphore creation to fail for the second process. * Bugfix: Issue #119: If a seek request is still open after EOF, restart transcoding. * Bugfix: Issue #119: To prevent frame/segment creation errors, the frame set and HLS code has been updated. * Bugfix: Avoid crashes during shutdown if cache objects have already been closed. * Bugfix: Issue #119: The AVSEEK_FLAG_FRAME set should be used to seek to frames when building frame sets. Otherwise, output images may vary if searched for or continuously decoded. * Bugfix: The conversion of PTS to frame number and vice versa for frame sets was incorrect if TBR did not equal frames per second. * Bugfix: Fixed seek requests that are being ignored with frame sets. * Bugfix: When transferring from cache to the Fuse buffer, avoid a possible 1 byte overrun. * Bugfix: Issue #143: To avoid occasional EPERM failures, missing synchronisation objects were added. * Bugfix: Issue #144: To fix the crashes that may have been caused by them, the variables impacted by a potential threading issue were marked as "volatile." * Bugfix: Closes#1037653: Fix build with GCC-13 * Bugfix: Update docker build for Debian Bookworm * Enhancement: Record milliseconds for every log event. * Enhancement: make check: added a file size check to frame set tests. * Optimisation: When reopening after invalidating the cache, the size remained at 0. The original size is now once again reserved in order to prevent reallocations. * Optimisation: To avoid reallocations, save enough space in the cache buffer to hold the entire frame set. * Optimisation: Checking folders to see if they can be transcoded is completely pointless. Directories are now immediately skipped. * To avoid problems with logfile viewers, renamed built-in logfiles to *_builtin.log (removing the double extension). Important changes in 2.13 (2023-01-15): * Added --prebuffer_time parameter. Files will be decoded until the buffer contains the specified playing time, allowing playback to start smoothly without lags. Works similar to --prebuffer_size but gives better control because it does not depend on the bit rate. An example: when set to 25 seconds for HLS transcoding, this will make sure that at least 2 complete segments will be available once the file is released and visible. * Feature: Issue #140: Filtering the files that will be encoded has been added. A comma-separated list of extensions is specified by the --include_extensions parameter. These file extensions are the only ones that will be transcoded. The entries support shell wildcard patterns. * Feature: The --hide_extensions parameter syntax has been extended. The entries now support shell wildcard patterns. * Bugfix: Issue #139: Additional files could be added using the --extensions parameter. However, this is no longer necessary; in the past, a file's extension determined whether or not it would be transcoded. Files with unknown extensions would be ignored. The extension is no longer important because FFmpegfs now examines all input files and recognises transcodable files by the format. The outdated --extensions argument was removed without substitution. * Bugfix: Fixed crash when implode() function was called with an empty string. Happened with Windows GCC 11.3.0 only. Important changes in 2.12 (2022-08-27): * The code has been run through clang-tidy to identify bug-prone or inefficient code, and to find parts that could be modernised to C++17. Several issues could be resolved. Sometimes, many lines of code could be replaced by a few. Some parts run far more efficiently than before. C++17 is cool. I need to get a t-shirt. * Bugfix: In get prores bitrate(), a crash that might have happened under unusual circumstances has been corrected. If the best match resolution could not be found, array access out-of-bounds could happen. * Bugfix: Several unlikely, but potential problems that could have happened when subtitle decoding failed or delayed video/audio packets couldn't be decoded have been fixed. * Bugfix: An internal problem could cause the application to crash. Should never happen, though. Fixed anyway. * Bugfix: Sometimes, the last segment's estimated size was incredibly small - about 2 bytes. Each segment should have the same predicted size as it is calculated simply by dividing the projected size of the entire file by the number of segments. Following transcoding, the size was accurate. Important changes in 2.11 (2022-06-16): * Feature: Issue #86: Smart transcode now detects if a source file is audio only and uses the correct target format. For example, with --destination=webm+mp3, if one MP4 input file contains a video stream and another an audio stream only, the resulting files will be WebM (for the video input) and mp3 for the audio only file. * Feature: Issue #137: Add --no_subtitles option to turn subtitles off. * Bugfix: Smart encode selected the video format for cue sheet tracks, regardless of the input format. This has been fixed now. * Bugfix: Fix a crash that occurs when a DVD/Blu-ray is transcoded to audio only. * Bugfix: If the track performer field in the cuesheet is blank, try album performer instead. * Bugfix: Failing to mount Fuse during "make check" went unnoticed as the result code (which was supposed to be 99) was actually 0. Return the correct result code, failing the operation as expected. * Bugfix: The Docker build command contained a "make check" which actually failed altogether. Step has been removed. "make check" mounts Fuse, but this requires privileges that do not exist during "docker build". * Bugfix: On error, mremap () returns MAP_FAILED rather than NULL. Fixed a check for incorrect error conditions, which could cause the application to crash or return illogical error messages. * Bugfix: Issue #119: Fix a problem that caused frame set generation to fail sometimes. It seems to be related to the nremap() issue. * Generally revisited documentation, logging, and display texts. Improved grammar, formatting, and fixed quite a few typos that escaped all proofreading sessions. * The FFmpeg API INFO and DEBUG level log output has been changed to the FFmpegfs DEBUG level. What FFmpeg considers "INFO" is far too chatty. * Frequent memory reallocations when creating HLS segments have been reduced to speed up processing. * Optimised logging to save CPU time by not formatting log entries that are not written anyway at their log level. * Logging has been revised to shorten file paths and remove mount, input, and cache paths. Log the additional portion only to reduce log file size and improve readability. * Bugfix: To fix the build with GCC 12, add the missing include headers (closes: #1012925). Important changes in 2.10 (2022-04-26): * Feature: Issue #123: New command line option to hide files by extension. Example: --hide_extensions=jpg,png,cue would stop covers and cue sheets from showing up. * Feature: Issue #120: Added subtitle support. Subtitle streams can now also be transcoded to the output files. Separate SRT or VTT files will be incorporated as subtitle streams. * Bugfix: Fixed memory leak in encode_audio_frame(). * Bugfix: Issue #122: Last song was missing from cuesheet files. * Bugfix: Issue #129: Files remained zero size when previously transcoded. * Bugfix: Issue #130: Fix file sizes can be incorrectly reported by ls but are correct when data is read. * Bugfix: Duration was not saved in cache SQLite database. * Bugfix: Issue #131: Sometimes video parameters for some Blu-ray or DVD chapters cannot be detected by FFmpeg API. Transcode then failes - fixed by using data from the Blu-ray directory or DVD IFO instead. * Lowest supported FFmpeg API version raised to 4.1.8 "al-Khwarizmi". * Dropped libavresample support, library was removed from FFmpeg API after 3.4.9. * Deprecated previous channel layout API based on uint64 bitmasks. * Deprecated swr_alloc_set_opts() and swr_build_matrix(). * Going C++17 now: The packet queue has been recoded in C++17 to support external subtitles files. As C++17 is required now, why not go all the way: Starting to replace legacy C++ and somewhat C-like parts with real C++. * Using std::shared_ptr to ensure proper memory allocation/free. Important changes in 2.9 (2022-02-16): * Feature: Issue #97: Added options to chose different codecs. The audio codec can be selected with --audiocodec, for videos use --videocodec. * Feature: Issue #109: Allow user defined file extensions for source files. By default, only standard extensions are accepted, i.e., mp4, ts, avi etc. Arbitrary file extensions can be defined now, e.g. using --extensions=xxx,abc,yxz,aaa to also convert files ending with .xxx, .abc and so on. * Feature: Issue #121: Added MKV support. New format can be selected with --desttype=mkv. * Bugfix: Issue #112: Fixed Docker detection. * Bugfix: Issue #110: Docker build command failed, added missing libchardet and allow libdvdread4 or *8 to be used, whatever available. * Bugfix: Fixed crash when video had no audio. * Bugfix: Issue #112: Fixed access problems with frame sets and HLS. * Bugfix: Issue #119: Fixed problem that caused frame set generation to fail sometimes. * Bugfix: Fixed JPG frame set generation. Suddenly FF_COMPLIANCE_UNOFFICIAL was required to have FFmpeg API accept the codec. * Enhancement: Issue #67: Enhance file size prediction. * Bugfix: Need to synchronise screen log. Concurrent entries by separate flags created garbled output. * Bugfix: Avoid creating an HLS segment number which is out of bounds (higher than the expected number of segments). * Enhancement: Removed QMake support, replaced with CMake. Important changes in 2.8 (2021-11-29): * Bugfix: Issue #102: Not all SQL queries where case sensitive, causing cache confusion. Several database entries were created, but only one was updated. Made all queries case sensitive. * Bugfix: Issue #91: Fixed HLS problems with cache causing garbled videos and hick-ups in audio. Make sure that the cache is clean when transcoding starts. There should be no remains left, all segments must be created or recreated anyway. Do not append to cache when writing. This caused cache files to become larger and larger. * Enhancement: Issue #103: If requested HLS segment is less than X (adjustable) seconds away, discard seek request. Segment would be available very soon anyway, and that seek makes a re-transcode necessary. Can be set with --min_seek_time_diff. Defaults to 30 seconds. * Feature: Issue #105: Added Free Lossless Audio Codec (FLAC) support. Activate with *--desttype=FLAC*. * Feature: Issue #101: Sample format for audio files can be selected via command line with --audiosamplefmt. Possible values are 0 to use the predefined setting, 8, 16, 32, 64 for integer format, F16, F32, F64 for floating point. Not all formats are supported by all destination types, selecting an invalid format will be reported as error and a list of values printed. Defaults to 0 (Use same as source or the predefined format of the destination if source format is not possible). Important changes in 2.7 (2021-11-08): * Bugfix: Issue #92: Fixed crash when hardware decoding failed. The problem is that the FFmpeg API very late reports that it cannot decode the file in hardware. To find out about that, the source file must be decoded until the first video frame is encountered. It would be very time consuming to do this on every file (decode until it is clear that the file is supported, then actually start transcoding it from scratch). There is no feasible way to automatically handle the situation. To get around this a --hwaccel_dec_blocked parameter has been added. If hardware decoding fails, check the log for a message similar this: "[vp9 @ 0x7fe910016080] No support for codec vp9 profile 0." If VP9 profile 0 is not supported, the parameter would be: --hwaccel_dec_blocked=VP9:0 This will tell FFmpegfs to decode the file in software. To block VP9 as a whole, the parameter would be --hwaccel_dec_blocked=VP9. To block both profile 0 and 1, use --hwaccel_dec_blocked=VP9:0:1. The parameter can be repeated to block even more codecs. * Bugfix: Issue #96: Fixed potential buffer overrun and crash when reading corrupted input files. * Enhancement: Issue #99: Report command line error if --desttype specifies audio format first, or if the second format is not audio only. Avoid misinterpretations. For example, --desttype=aiff+mov would create MOV files out of any input. Correct would be --desttype=mov+aiff which will create MOV files out of videos and AIFF from audio files, as expected. Important changes in 2.6 (2021-09-04): * No new features, just a bugfix. See V2.4 for details. Important changes in 2.5 (2021-06-18) * Feature: Issue #63 - Hardware acceleration for encoding/decoding is partly implemented, VAAPI/MMAL/OMX/V4L2 are currently available only. - Supported hardware: V4L2/VAAPI (Intel) and V4L2/MMAL/OMX (Raspberry). - VAAPI: H264, H265/HEVC, MPEG-2 and VP-8 decoding and H264 encoding. - VAAPI: MJPEG and VC-9 do not work (yet). - MMAL: H264, MPEG-2, MPEG-4 and VC1 decoding. - OMX: H264 encoding. - V4L2: H263, H264, H265, MPEG1/2/4, VC-1, VP8/9 encoding/decoding. * Feature: Added unit tests for hardware acceleration. Failing tests will report as SKIPPED and not fail the whole test. * Note: Which hardware en/decoder actually works depends on what your hardware supports. * Call for testers: Have a CUDA capable graphics adapter and interested in testing? Please write me an E-Mail. Important changes in 2.4 (2021-09-04) * Bugfix: Issue #90: Make sure that one keyframe gets inserted at the start of each HLS segment. Important changes in 2.3 (2021-06-11) * Enhancement: Issue #80: Open input video codec only if target supports video. Saves resources: no need to decode video frames if not used. * Enhancement: Issue #81: If source format has no audio, and the target supports no video (e.g.WAV/MP3), the files have shown up zero sized. These will now not be visible when doing ls. When trying to open them "File not found" will be returned. * Added "configure --enable-debug" to create binaries with debug symbols. Defaults to the optimised version. * Feature: Issue #73: Cue sheet tracks now play "gapless" if played in order. Whenever a track is started, the next track will automatically be transcoded as well. * Feature: Issue #66 and issue #82: Added cue sheet support. If a file with cue extension is found with the same name as a media file or if a cue sheet is embedded into it (a tag named CUESHEET), tracks defined in it will show up in a virtual directory. * Feature: Issue #83: Character conversion for cue sheet files. Automatically detects the character encoding of the cue sheet. and converts as necessary. * Feature: Issue #78: Duplicate ARTIST to ALBUMARTIST tag if empty * Feature: Issue #79: Added Docker support. * Fixed deprecation: 2021-03-17 - f7db77bd87 - lavc 58.133.100 - codec.h Deprecated av_init_packet() * Fixed API compatitbility: Many pointers made const as of 2021-04-27. Although reasonable, this breaks API compatibility with versions older than 59.0.100, * Bugfix: find_original "fallback" method did not correctly handle the new filename format (extension added, not the original one replaced). * Bugfix: Issue #87: Segments are now properly separated, making sure that e.g. segment 3 only goes from 30 seconds up to 40 (including 30, but not 40 seconds). * Bugfix: Issue #88: HLS audio and video now stay in sync after longer playback (more than 30 minutes) or after seek operations. Important changes in 2.2 (2021-02-06) This is a maintenance release, bugfixes only. * Bugfix: Issue #75: Fix crash when opening mp3 output with Dolphin. * Bugfix: Issue #70: Possible crash in Buffer::init: Should not assert if duration is 0 (and thus segment count 0). Report internal error and go on. * Bugfix: Issue #70: Do not set duration to 0 from cache but leave unchanged. Caused HLS transcoding to fail if more than one transcoder was concurrently started. * Bugfix: Possible crash in transcoder_thread: Decoder object could have been used after being freed. * Bugfix: Stupid blooper. WAV and AIFF size was always calculated for a mono file, thus for stereo files resulting in only half the correct size. * Bugfix: Corrected documentation, "make checks" should read "make check", funny this went unnoticed for over 3 years... * Bugfix: Issue #74: Album arts were only copied from MP3/4 sources. Removed restriction, if the input file contains an album art it will be copied to the target (if supported, of course, e.g., to mp3 or mp4. Ogg is not yet supported because embedding album arts in Ogg can only be done by an unofficial workaround). * Bugfix: Issue #71:: Virtual directories were missing dot and dot-dot nodes. Important changes in 2.1 (2020-12-14) * Feature: Add BLURAY_VIDEO_FORMAT_2160P (UHD) * Feature: Implemented in 1.7, removed experimental state for --win_smb_fix now. Windows seems to access the files on Samba drives starting at the last 64K segment simply when the file is opened. Setting --win_smb_fix=1 will ignore these attempts (not decode the file up to this point). * Feature: --win_smb_fix now defaults to 1 (fix on by default). Has no effect if the drive is accessed directly or via Samba from Linux. * Bugfix: Fixed grammatical error in text: It's "access to", not "access at". * Bugfix: Did not transcode some source files with invalid DTS. * Bugfix: Cosmetical - No need to log date/time twice in syslog. * Bugfix: Cosmetical - Fix man page/online help for --recodesame parameter. * Bugfix: Report correct segment duration * Bugfix: Avoid crash if opening next HLS segment failed. Should not ignore this, but report it instead and stop transcoding. * Cosmetical: Log cache close action at trace level * Cosmetical: Shorter log entry when opening cache files Important changes in 2.0 (2020-09-13) Hurray! This is release 2.0! * Feature: No new features, new release 2.0 after feature freeze. * Bugfix: Issue #64 - Fixed playback stopping prematurely on some files. Important changes in 1.99 (2020-07-18) * Libav support has been dropped. There is no activity on https://git.libav.org/?p=libav.git since 21.08.2019, and some features that FFmpegfs required were already lagging behind FFmpeg API. Supporting Libav already bound a lot of my time that I could better spend on new features or fixes for FFmpegfs. * Feature: Add PNG/BMP/JPG frame sets to 'make check'. Checks number of files and cp operations in arbitrary order with wildcards and absolute file names. * Feature: Add HLS segments to 'make check'. Checks number of segments, the segment sizes and correct file names. * Feature: Moved FFmpeg capabilities (formats) from --version/-V command to new -caps/-c parameter to keep version information brief. * Bugfix: Issue #61 - fix timeout problem when accessing JPG in arbitrary order. * Bugfix: Issue #58 - Build list when ls/cp path/to/flles/00001.png is done. Access failed because the file was not found. * Bugfix: Issue #59 - *.m3u8 files were tried to be transcoded while they should simply be passed through. Added to ignore and pass through list. * Bugfix: Issue #57 - Correctly expand tilde when ~/ is used, for example in "ffmpegfs --logfile=~/ffmpegfs.log". * Bugfix: Issue #60 - Reopen cache file after it has been closed so that image frames can be accessed after the file has been fully decoded. Important changes in 1.98 (2020-04-15) * Cool, there's an online revivew on Linux Uprising, you can read it here: https://www.linuxuprising.com/2020/03/ffmpegfs-is-fuse-based-filesystem-for.html * Support: FFmpegfs has recently been added to Debian sid and Debian Bullseye. It is also available in Ubuntu 20.04 and Linux distributions based on it. * Feature: HLS: Introducing direct segment access. If e.g. segment no. 333 is opened, ffmpegfs will seek to this position and start transcoding the segment immediately. *Please note that this feature is still experimental and may produce unexpected results.* * Support: No longer creating a user/group ffmpegfs while "make install". The user is not really required, just bloats the system's user database. * Support: Reduced quality of the test video to make the distribution archive slimmer. A full HD (1920x1280) video at 60 frames per second was a bit of an overkill anyway. 720x400 at 30 fps should be enough for everybody. * Feature: Cache dir changed to ${XDG_CACHE_HOME:-~/.cache}/ffmpegfs (as specified in the XDG Base Directory Specification). Falls back to ${HOME:-~/.cache}/ffmpegfs if not defined. Only if executed with root privileges, "/var/cache/ffmpegfs" will be used (e.g. if invoked via /etc/fstab entry). * Feature: Changed PTS generation: For DVD/Blu-ray chapters they will not start at 0 for each chapter, but at the real time the chapter begins in its title. Fixes #51. * Feature: Issue #52 - Added --audiochannels option to select a different number of channels. Defaults to 2 (stereo), may be set to 1 to create mono files. Set to 0 to keep the original number of channels. * Bugfix: Issue #46 - Ensure the selected bitrate is used. Files could become much larger than expected. There's a strange FFmpeg API behaviour behind that, added the solution used in ffmpeg.c to fix. * Bugfix: Issue #48 - Properly handle incorrectly authored DVDs with missing SRI_END_OF_CELL marks after cells. * Bugfix: Issue #49 - Avoid creating HLS last segments shorter than 200 ms, avoid stalls when the total playtime is a multiple of the segment size, e.g. 10 seconds. * Bugfix: Issue #54 - Made sure no duplicate filenames get created. This changes the output name scheme, e.g. if two files xyz.ts and xyz.wmv exist and the destination type is mp4, two output files named xyz.ts.mp4 and xyz.wmv.mp4 appear. An additional file xyz.mp4 will show up with its real name. To continue using the old names, add --oldnamescheme=1 to the command line. * Bugfix: Online help and docs state --autocopy=OFF would turn the function off, but this actually was NONE. Changed to match documentation. * Known bug: Libav support for videos seems broken. Not sure if this will be fixed or Libav be simply dropped. Important changes in 1.97 (2020-01-21) * Support: * Feature: Added support for HLS (HTTP Live Streaming). Select desttype=hls to enable. * Feature: Added checks for mov/mp4/prores/webm video format. * Bugfix: Moved video deinterlace filtering before rescaling. Deinterlace does not work properly on rescaled videos, what a suprise. Especially caused strange results on Blu-ray sources, created blurred frames if downscaled from HD to SD (or lower) before deinterlacing. * Bugfix: Avoid EINVAL errors in case the cache file ends up at zero size. Minor problem, but ugly. * Bugfix: Cache structure was not properly initialised, causing invalid values in the database. * Bugfix: Properly handle case when start_time is AV_NOPTS_VALUE (frame sets only) * Bugfix: Corrected mistake in online help: clear-cache should be clear_cache instead. * Bugfix: Issue #43 - fix garbled first 12 frames. Enhanced overall picture quality. * Workaround: Issue #45 - fix garbled Blu-ray/DVD playback. Just a workaround, the problem is somewhere else. * Due to copyright uncertanties and because the public domain license used is controversal, all demo files in test/srcdir have been replaced with own works and put under the CC0 1.0 Universal license. * Known bug: Libav support for videos seems broken. Not sure if this will be fixed or Libav be simply dropped. Important changes in 1.96 (2019-11-18) This is a pre-release towards the new version 2.0 coming up soon. * Feature: Added version check and auto update to cache database. Older database versions will now automatically upgraded to the latest structure. * Feature: Transcode videos to frame works transparently for any input now (DVD, Blu-ray and VideoCD). * Bugfix: Fix for "prores can't allocate memory #41". * Bugfix: Do not shrink cache when reopening it. * Known bug: Important changes in 1.95 (2019-05-23) This is a pre-release towards the new version 2.0 coming up soon. * Feature: Added transcode videos to frame images option. Video files can be mounted to folders with jpg/png/bmp files for each video frame. * Feature: Reencode to same file format as source file. Normally files that already have the selected output format will not be recoded. Added --recodesame option to allow transcoding to the same format. Important changes in 1.11 (2020-04-15) * Cool, there's an online revivew on Linux Uprising, you can read it here: https://www.linuxuprising.com/2020/03/ffmpegfs-is-fuse-based-filesystem-for.html * Support: FFmpegfs has recently been added to Debian sid and Debian Bullseye.

Falls back to ${HOME:-~/.cache}/ffmpegfs if not defined. Only if executed with root privileges, "/var/cache/ffmpegfs" will be used (e.g. if invoked via /etc/fstab entry). * Feature: Changed PTS generation: For DVD/Blu-ray chapters they will not start at 0 for each chapter, but at the real time the chapter begins in its title. * Feature: Issue #52 - Added --audiochannels option to select a different number of channels. Defaults to 2 (stereo), may be set to 1 to create mono files. Set to 0 to keep the original number of channels. * Bugfix: Issue #46 - Ensure the selected bitrate is used.

To continue using the old names, add --oldnamescheme=1 to the command line. * Bugfix: Online help and docs state --autocopy=OFF would turn the function off, but this actually was NONE. Changed to match documentation. * Libav support has been dropped. There is not activity on https://git.libav.org/?p=libav.git since 21.08.2019, and some features that FFmpegfs required were already lagging behind FFmpeg API. Supporting Libav already bound a lot of my time that I could better spend on new features or fixes for FFmpegfs. Important changes in 1.10 (2020-01-21) * Feature: Added checks for mov/mp4/prores/webm video format. * Bugfix: Moved video deinterlace filtering before rescaling. Deinterlace does not work properly on rescaled videos, what a suprise. Especially caused strange results on Blu-ray sources, created blurred frames if downscaled from HD to SD (or lower) before deinterlacing. * Bugfix: Avoid EINVAL errors in case the cache file ends up at zero size. Minor problem, but ugly. * Bugfix: Cache structure was not properly initialised, causing invalid values in the database. * Bugfix: Skip corrupted and discarded video frames to avoid blurps. * Bugfix: Corrected mistake in online help: clear-cache should be clear_cache instead. * Bugfix: Issue #43 - fix garbled first 12 frames. Enhanced overall picture quality. * Workaround: Issue #45 - fix garbled Blu-ray/DVD playback. Just a workaround, the problem is somewhere else. * Due to copyright uncertanties and because the public domain license used is controversal, all demo files in test/srcdir have been replaced with own works and put under the CC0 1.0 Universal license. * Known bug: Libav support for videos seems broken. Not sure if this will be fixed or Libav be simply dropped. Important changes in 1.9 (2019-11-18) * Support: Code has now been tested to work on ARMv7 (32 bit). * Feature: Documented the whole project with Doxygen. * Feature: Implemented a thread pool. File open (and thread starts) are now much faster than before. The thread pool also ensures that not more threads than configured are started. Defaults to 16x the number of processor cores available. * Feature: Added Apple Lossles Audio Compression (ALAC) support. * Feature: Added optional graphviz to configure, only required for Doxygen. * Feature: Updated INSTALL.md with missing prerequisites. Rearranged paragraphs, mentioning building from git first was confusing. * Feature: Moved cache directory from rather unusual /tmp/ffmpegfs location to /var/cache/ffmpegfs. * Bugfix: Fixed several warnings if compiled for 32 bit. * Bugfix: Removed unused xmlint prerequisite from configure. * Bugfix: Video and audio was out of sync on android devices. * Bugfix: Fix crash when Blu-ray video without audio was opened. * Bugfix: Cache files were left at the predicted size if it was larger than the result size. Size is now correctly capped to the correct result size. * Fixed deprecation in fpcompare: 2018-04-01 - f1805d160d - lavfi 7.14.100 - avfilter.h Deprecate use of avfilter_register(), avfilter_register_all(), avfilter_next(). Added av_filter_iterate(). Important changes in 1.8 (2019-05-23) This is a bugfix/maintenance release with only a few minor features added. * Feature: Added Doxygen documentation. * Feature: Report all errors together with error number. * Feature: More detailed error handling. * Feature: Added "make wipe-all" to really clean up all generated files. * Bugfix: Do not report "Not a directory" error for virtual directories. Not an error, it's a feature. * Bugfix: Fixed make dist: checks did not work. * Bugfix: Fixed make clean: some Doxgen files were not removed. * Bugfix: Properly catch "no memory" errors. * Bugfix: Deinterlacing filter only worked for YUV videos. * Bugfix: Removed the check for invalid chapters - did not work as expected. * Bugfix: Wrong bitrate for PAL (was 30 fps instead of 25 fps) and assume PAL if bits are invalid. * Bugfix: Fixed potential crash in DVD handling. * Bugfix: Do not add libavresample if libswresample is present. Saves build time. * Bugfix: Removed dependency on unused libdvdnav. Saves buildtime. * Bugfix: Fixed two (probably rare but possible) crashes. * Bugfix: Image now not converted when the destination type is a video format. Important changes in 1.7 (2019-02-26) * Feature: Windows seems to access the files on Samba drives starting at the last 64K segment simply when the file is opened. Setting --win_smb_fix=1 will ignore these attempts (not decode the file up to this point). * Feature: Added "Auto Stream Copy" option. This will copy audio or video streams to the output file rather than recoding. Reduces computing time and CPU load. * Feature: Sped up DVD/Blu-ray/VCD access drastically. FUSE calls getattr like crazy, using cached data now. * Feature: Extended stream copy: now any codec can be copied if supported by target container using --autocopy=MATCH option. * Feature: Added full virtual titles to DVD, Blu-ray and Video CD. Creating one virtual file per chapter is very nice for music disks as it allows access to every single title very easily. For movies it is better to have it in one piece. * Feature: Enhanced win_smb_fix=1 functionality to hopefully catch all Windows incidents. * Feature: Added min_dvd_chapter_duration parameter. DVD chapters shorter than this will be ignored. Defaults to 1 second. * Bugfix: Decimal seconds in duration was wrong. Fixed. * Bugfix: This was a bad one: The application crashed with a protection fault if there was not enough disk space on the cache drive. This is now properly reported and transcoding aborted. Thanks for Muf for reporting the issue. * Bugfix: Fixed crash when DVD nav packet was missing * Bugfix: Fixed clang compatibility. Project did not build with clang, this has gone unnoticed for a while... * Bugfix: Fixed terrible miscalculation of DVD play time. No one told me the values are BCD, not decimal... * Bugfix: Fixed conversion of DVD chapters consisting of more than one cell. * Bugfix: Fixed pts/dts generation * Known bug: Some Blurays are not recoded properly. The resulting files are much larger than expected, as a matter of fact larger than the source (birates > 27 MBit). Happens only for some sources. Important changes in 1.6 (2019-01-11) * Feature: Made all parameters like --profile case insensitive. * Feature: Added Apple MOV, Apple Prores and Apple AIFF formats. * Feature: Enable "Smart Transcoding": To enable, specify --desttype=AUDIO+VIDEO, e.g. --desttype=MOV+AIFF will automatically convert video files to MOV and audio to AIFF. * Feature: New parameter --level allows selecting a profile for Prores: proxy, lt, standard or hq. * Feature: Added MOV target format * Feature: Added AIFF target format * Feature: Smart conversion option ("Smart Transcode") * Feature: Added level option for Prores * Feature: Added Apple Prores support * Feature: Do not "upgrade" mono audio to stereo. Create mono audio stream. * Feature: Speed up DVD conversion significantly by using IFO data instead of probing each chapter. * Feature: Added DVD angle support.Chapters with angles will show as separate files. * Feature: Speed up Blu-ray conversion significantly by using the directory instead of probing each chapter. * Feature: Speed up VCD conversion. * Feature: EXPERIMENTAL: Windows seems to access the files on Samba drives starting at the last 64K segment simply when the file is opened. Setting win_smb_fix=1 will ignore these attempts (not decode the file up to this point). * Bugfix: Suspend/decoding timeouts did not work. Transcoding never timed out... * Bugfix: Fixed memory leak when using the deinterlace option. * Bugfix: Deinterlace did not always work. * Bugfix: Fixed memory leaks. * Bugfix: Report correct error if directory mounted twice. * Bugfix: Silence chatty log outputs. * Bugfix: Fixed GPF when accessed. * Bugfix: Fixed GPF when channel layout changed during playback. * Bugfix: If transcode failed, the error was sometimes not reported to the client process, causing it to hang. * Bugfix: Sometimes tried to create WebM files with zero width (failed to transcode). * Bugfix: Avoid mpeg-4 profile/pixel format mismatches. * Bugfix: Fixed creating zero sized files from DVDs when chapter playtime < 1 s. * Bugfix: Update timeout when client just holds the file open without reading. * Bugfix: Properly honour client exit (end wait for data). * Bugfix: Issue #23: do not block open with a read waiting for data. * Bugfix: WebM files had no duration. Added duration to Matroska container. * Bugfix: Fixed EOF detection for Blu-ray chapters. * Bugfix: Force mpeg format for DVDs to avoid misdetections. * Bugfix: Force mpegts format for Blurays to avoid misdetections. * Bugfix: Take DVD chapter duration from IFO as probed playtime from VOB segment is sometimes wrong. * Bugfix: Take Blu-ray chapter duration from directory as probed playtime from MTS segment is sometimes wrong. * Fixed deprecation: Important changes in 1.5 (2018-06-08) * Feature: Added WebM output format using VP9 video and Opus audio codec. * Feature: Input format check is now done by FFmpeg, that means if the input file is supported by FFmpeg, it will be transcoded. For performance, files are not opened and scanned, the file's extension is checked only (e.g. mp3, wav, rm etc.). * Feature: Replaced mutagen-inspect with internal code which also works with WAV and WebM. test_tags works for all formats now. python-mutagen is no longer required. * Feature: Check if sample rate or sample format is supported by audio codec and change if necessary. Avoid transcode fails e.g. if 44.1KHz sampling rate is requested but not supported (e.g. OPUS only supports 8K, 16K, 24K or 48K). Select nearest supported sample rate or sample format. Important changes in 1.4 (2018-05-30) * The timeout for suspend and abort have been changed. Decoding will now be suspended after 15 seconds (formerly 2 minutes). If no activity is detected after further 15 seconds (formerly 3 minutes) decoding will be aborted. This will only happen if the file is actively closed, so if playback is simply paused decoding will continue. The new limits proofed to be fine and reduce system load significantly. * Feature: Enhanced logging, added a colour profile to screen logs and raised or lowered some messages log levels appropriately. Also added a few informative log messages. * Feature: Blu-ray support: Detect Blu-ray files in directories and list separate chapters and titles as separate files. * Feature: DVD support: Detect IFO files and list separate DVD chapters or programs as separate files. * Feature: S/VCD support: Detect Video CDs in directories and list chapters as separate files. * Feature: Changed the fuse operations code module to c++ (minimise danger of memory leaks or buffer overruns) * Feature: Added --enablescript option that will add virtual index.php to every directory. It reads scripts/videotag.php from the ffmpegs binary directory. This can be very handy to test video playback. Of course, feel free to replace videotag.php with your own script. * Feature: By default ignore decoding errors so that transcoding does not stop just because a few frames are garbled. Can be disabled with the "decoding_errors" option. * Bugfix: Sometimes the pixel format could not be detected, raising an assert/application crash with newer FFmpeg API versions. Fixed by setting it to the output format. This will mostly ever create defect encoder results, but at least the FFmpegfs process will not be shut down writing a core file. * Bugfix: Set mp4 profile to high/3.1 to enable playback under enable playback under Win 7. * Bugfix: Fixed formatting of help text. * Workaround: Fixed Libav support: Deinterlace code did not compile. Should be possible to get it working, but for now it is simply disabled. But honestly I don't want to get it working. I am thinking of dropping Libav completely. * Fixed deprecation: 2018-xx-xx - xxxxxxx - lavf 58.9.100 - avformat.h Deprecate use of av_iformat_next(), av_oformat_next(). Important changes in 1.3 (2018-05-04) Changes in this release: * Feature: Added option to deinterlace video if required (will improve picture quality when viewed in browsers via HTML5. * Feature: Set stream duration from source file as hint for encoder. * Feature: Enhanced logging output for better readability. * Feature: Added pre-buffer option. Files will be decoded up to this limit first before made accessible. This ensures smooth startup. * Feature: Enhanced configure that checks whether libavresample or libswresample is present. * Feature: Improved recoding detection. Files are recoded if the source file size or timestamp changes, or different encoding options are selected (e.g. a different bitrate, vidoe size etc.). * Feature: Allow profiles for target browsers or players. Currently selectable: NONE no profile FF optimise for Firefox EDGE optimise for MS Edge and Internet Explorer > 11 IE optimise for MS Edge and Internet Explorer <= 11 CHROME Google Chrome SAFARI Apple Safari OPERA Opera MAXTHON Maxthon Defaults to NONE * Feature: enhanced error output for SQLite (if supported by library version) * Feature: copy album arts from source if supported by target format (MP3/4). Use --noalbumarts parameter to disable, e.g., for streaming files. * Bugfix: Only four lines of code: Avoid locking other clients when trying to get the size of a file currently being decoded. Also speeds up directory access quite significantly. * Bugfix: Fixed lost frames at end of files (files where cut short) * Bugfix: Fixed crash when video files were transcoded to audio only (e.g. mp3) * Bugfix: Make WAV size prediction more accurate * Bugfix: Recode existing cache files if not found in database (handle database inconsistencies). * Bugfix: Fixed sharing problems with sqlite database when accessed by multiple instances. * Bugfix: Files were truncated (mostly mp3) when cp'ed directly while transcoding. Now files will have the final size as expected. * Bugfix: Create valid WAV header for files transcoded on-the-fly. * Bugfix: Ensure a file gets recoded when the last attempt failed. * Bugfix: Ensure that transcoding errors get passed on to calling process, e.g. cp or rsync. Otherwise copy operations might not notice that the file is invalid. FFMpeg has evolved, many API parts have been deprecated and will be dropped soon. This release adopts these changes by conditionally using the new APIs from the FFMpeg version on that they are available. * Fixed deprecation: 2017-xx-xx - xxxxxxx - lavr 4.0.0 - avresample.h Deprecate the entire library. Merged years ago to provide compatibility with Libav, it remained unmaintained by the FFmpeg project and duplicated functionality provided by libswresample. swresample is the preferred library in FFMpeg, so it will be used if compiled with FFMpeg by default, even before being deprecated. With libav, which makes libavresample available only, the latter will be used. * Fixed deprecation: 2016-04-21 - 7fc329e - lavc 57.37.100 - avcodec.h Added a new audio/video encoding and decoding API with decoupled input and output -- avcodec_send_packet(), avcodec_receive_frame(), avcodec_send_frame() and avcodec_receive_packet(). * Fixed deprecation: 2018-01-xx - xxxxxxx - lavf 58.7.100 - avformat.h Deprecate AVFormatContext filename field which had limited length, use the new dynamically allocated url field instead. * Fixed deprecation: 2018-xx-xx - xxxxxxx - lavf 58.9.100 - avformat.h Deprecate use of av_register_input_format(), av_register_output_format(), av_register_all(), av_iformat_next(), av_oformat_next(). NOTE: av_iformat_next/av_oformat_next() lack a replacement (currently still used in tools/probetest.c "static void probe" in 58.10.100) * Fixed deprecation: 2018-xx-xx - xxxxxxx - lavc 58.10.100 - avcodec.h Deprecate use of avcodec_register(), avcodec_register_all(), av_codec_next(), av_register_codec_parser(), and av_parser_next(). Added av_codec_iterate() and av_parser_iterate(). * Fixed deprecation: 2016-04-11 - 6f69f7a / 9200514 - lavf 57.33.100 / 57.5.0 - avformat.h Added AVStream.codecpar, deprecate AVStream.codec. * Fixed deprecation: 2018-04-01 - f1805d160d - lavfi 7.14.100 - avfilter.h Deprecate use of avfilter_register(), avfilter_register_all(), avfilter_next(). Added av_filter_iterate(). nschlia@oblivion-software.de Important changes in 1.2 (2018-04-03) Changes in this release: * Fixed issue #4: File size was wrong when file was first accessed. * Fixed issue #5: Fixed crashes when transcoding. * Feature: None. This a bug fix release. nschlia@oblivion-software.de Important changes in 1.1 (2018-03-19) Changes in this release: * Fixed: make clean for checks did not delete all logs * Feature request #1: WAV output support (by github user Avuton) * Feature: OGG output support * Fixed: Did not write correct ID3v2 headers (thanks for the fix to gitbug user sdrik) * Feature: Include configure command line arguments and host OS in "-V" option. * Feature: Added --videoheight=HEIGHT and --videowidth=WIDTH parameters to allow video size change. If source video is larger it will be scaled down. If already smaller the size will be left as is. You should only set one parameter, if both are set the aspect ratio may be changed and the result look strange. * Feature: Added clear_cache option to clear the whole cache everytime the application is started. * Note: Dropped ISMV option as it did not work as expected, especially creating an mp4 on-the-fly did not work. The streamlined mp4 format already does the work. nschlia@oblivion-software.de Important changes in 1.00 (2018-01-19) Changes in this release: * Cheers! Made it! This is release version 1.0, the first production release. * Fixed compile for FFmpeg versions prior to 3.0. nschlia@oblivion-software.de Important changes in 0.95 (2017-12-29) NOTE: The cache format has changed and is not compatible with prior versions. Please do a "rm -Rf /tmp/ffmpegfs" before starting this version to create a new cache. TODO: see new TODO file from now on. Changes in this release: * Heureka! This is the first beta release towards V1.0. From now on only bug fixes will go into the code. * Implemented automatic cache maintenance (ensure cache size, disk space, delete outdated entries). * Fixed checks ("make check" works now. Known problem: mp4 sizes seem to differ when using different FFmpeg releases. Will be addressed soon.). * Fixed mp3 format (The mp3s were completely braindead.). * Fixed suspend timeout coming although file currently accessed. * Fixed crash during shutdown because sqlite was used too late. * Fixed handling of multiple destination types in same cache. * Properly pass on errno/save and store in cache database. * Additional database fields for target parameters (bitrate, error code etc.). Will be used in later versions to detect if a file needs re-transcoding. * Files will be recoded if source file changes (size or timestamp). * Report compiler version when run with -v parameter. * Set gcc optimisation higer (now -o3). nschlia@oblivion-software.de Important changes in 0.94 (2017-12-19) Changes in this release: * Decided to rename mp3fs to FFmpegfs because the project has grown far beyond a simple clone of mp3fs and the changes it will surely never be pushed back to the parent project. A big random applause to the makers of mp3fs for giving me a good head start! * Cache management: Keep cache size within limit, ensure min. disk space, prune oldest entries * Fixed many crashes * Fixed memory leaks * Fixed mp4 check suite * Added mp3 check suite * Added --disable_cache parameter * Added --prune_cache parameter. Starts cache pruning manually. * TODO: Add intelligent stream copy, e.g., if transcoding a transport stream that already represents a H264 video stream it would be possible to simply repackage it to a mp4 container without recoding. * TODO: Cover art support still missing nschlia@oblivion-software.de Important changes in 0.92-FFmpeg (2017-12-14) Changes in this release: * Files will now be decoded to /tmp/ instead of memory. * Full support for video files (mp4 target only). * Removed --statcachesize option as caching will be handled by new disk cache. * Fixed sync problems while accessing the same file concurrently * Fixed many crashes due to incorrect usage of FFmpeg * Cache directory user defineable * Delete cache entries after predefined time * Detect if file has changed and re-transcode * Limit cache size * Suspend transcode after n seconds * Exit transcode after n seconds * TODO: Add intelligent stream copy, e.g., if transcoding a transport stream that already represents a H264 video stream it would be possible to simply repackage it to a mp4 container without recoding. nschlia@oblivion-software.de Important changes in 0.91-FFmpeg (2017-10-04) Added FFmpeg for decoding and encoding. Changes in this release: * Replaced decoding and encoding with FFmpeg. * Removed discrete FLAC/Ogg/MP3 libraries. FFmpeg supports a wide range of formats, including these, so they are no longer required. * TODO: Supports a huge number of file formats now (run "mp3fs --codecs" for a list). * The standard target format is mp4 now (use "-o mp3" or "--output mp3" to change back to mp3). * Many other formats are possible, e.g. "-o ogg", they will be added later because due to the manner in which Fuse requires access to the files they need to be implemented with care. * See manual or run "mp3fs -h" for even more new options. * Run "mp3fs -f" to get a list of all supported input formats. * Caching of file attributes is now the default as if "--statcachesize=500" was given. Added "--statcachesize=0" to turn off (not really a bright idea, though). * TODO: Files will now be decoded to /tmp/ instead of memory if larger than 100MB. Added "--maxmemcache=X" to change. Examples for X: 80000, 80MB or 1GB. Do not set to a too large value as you may run out of memory. * TODO: Support for video files. * TODO: Add intelligent stream copy, e.g., if transcoding a transport stream that already represents a H264 video stream it would be possible to simply repackage it to a mp4 container without recoding. nschlia@oblivion-software.de Important changes in 0.91 (2014-05-14) This is mainly bug fixes. Changes in this release: * Fixed a segfault caused by an overflow reading the list of available decoders. * A number of problems with the previous distribution tar are now fixed. * The output of `mp3fs --version` has been made more complete. Important changes in 0.9 (2014-04-06) This is a major new release, and brings us very close to a 1.0 release! Changes in this release: * All transcoding code has been completely rewritten. Encoding and decoding have been abstracted out into base classes defining interfaces that can be implemented by different codec classes, with just a FLAC decoder and MP3 encoder at the moment. * The build system has been modified as well to support this usage. * A number of small bugs or code inefficiencies have been fixed. Important changes in 0.32 (2012-06-18) This release has a lot of bug fixes and some code cleanup. Changes in this release: * The file size calculation should always be correct. * A crash affecting programs like scp that might try to access past the end of the file has been fixed. * Too many other little fixes were made to list here. See the ChangeLog for full details. Important changes in 0.31 (2011-12-04) This is a minor update, with bug fixes and a new feature. Changes in this release: * The ReplayGain support added earlier now can be configured through the command line. * Filename translation (from .flac to .mp3) is now fixed on filesystems such as XFS that do not populate dirent.d_type. * A couple other minor bugs fixes and changes were made. Important changes in 0.30 (2010-12-01) This is a major new release, and brings mp3fs much closer to an eventual 1.0 release. Changes in this release: * Support for additional metadata tags has been added. (From Gregor Zurowski) * Documentation improvements: the help message is more useful, and a man page has been added. * Choosing bitrate is now done with a command-line or mount option, rather than the old comma syntax. * A new option to select LAME encoding quality is now available. (From Gregor Zurowski) * Debug output can be enabled at runtime. * Old external libraries included in distribution (StringIO, talloc) have been removed and replaced. * Numerous bug fixes have been made. (Some from Gregor Zurowski) ... 0.01 Initial release 06/Aug/2006 ======================================================================== Copyright (C) 2010-2014 K. Henriksson Copyright (C) 2017-2026 Norbert Schlia (FFmpeg support) This documentation may be distributed under the GNU Free Documentation License (GFDL) 1.3 or later with no invariant sections, or alternatively under the GNU General Public License (GPL) version 3 or later. ffmpegfs-2.50/FEATURES.md0000664000175000017500000005064415052412650010471 Hardware Acceleration ===================== The hardware acceleration feature depends heavily on the hardware used. As this is a personal project, I cannot go out and buy and test all possible devices. So I'll have to rely on you to report your issues so we can iron them out. Even different hardware supporting the same API may behave differently. Sometimes the format range is not the same, sometimes subfeatures are missing, and so on. ## How It Works Acceleration is done by specialised graphics adapters. The FFmpeg API can use several types using a range of APIs. As of today, even cheap on-board chips can do hardware acceleration. Here is an incomplete list. Hardware acceleration using hardware buffered frames: * VAAPI: Intel, AMD (Decoders: H.264, MPEG-2, MPEG-4 part 2, VC-1. H.265, H.265 10-bit on recent devices. Encoder: H.264, H.265, MPJEPG, MPEG-2, VP8/9, MPEG-4 part 2 can probably be enabled.) * VDPAU: Nividia, AMD (H.264, MPEG-1/2/4, and VC-1) * CUDA: Compute Unified Device Architecture (Decoders: VP9, H.264, MPEG-2, MPEG-4. Encoding: H.264, H.265), see https://developer.nvidia.com/ffmpeg and https://en.wikipedia.org/wiki/CUDA * QSV: QuickSync, see https://trac.ffmpeg.org/wiki/Hardware/QuickSync * OPENCL: Open Standard for Parallel Programming of Heterogeneous Systems, see https://trac.ffmpeg.org/wiki/HWAccelIntro#OpenCL * VULKAN: Low-overhead, cross-platform 3D graphics and computing API, requires Libavutil >= 56.30.100, see https://en.wikipedia.org/wiki/Vulkan_(API) These use software frames: * v4l2m2m: Intel (Encoders: H.263, H.264, H.265, MPEG-4, VP8). Decoders: H.263, H.264, H.265, MPEG-1, MPEG-2, MPEG-4, VC-1, VP8, VP9.) * OpenMAX: Encoding on Raspberry (H.264, MPEG-4. Requires key to unlock.) * MMAL: Decoding on Raspberry (H.264, MPEG-2, MPEG-4, VC-1. Requires key to unlock.) More information can be found at https://trac.ffmpeg.org/wiki/HWAccelIntro. ## Current Implementation ### Supported Hardware Acceleration APIs These APIs are implemented and tested. VAAPI mostly targets Intel hardware, but there are other hardware vendors that offer support now. MMAL and OpenMAX are supported by Raspberry PI boards. | API | Decode | Encode | Description | Details see | | --------- | ------ | ------ | ----------------------------------------------- | ------------------------------------------------------------ | | **VAAPI** | x | x | Video Acceleration API (VA-API), formerly Intel | https://en.wikipedia.org/wiki/Video_Acceleration_API

It may be possible that other APIs work, but this has not been confirmed yet. To enable hardware support, use these parameters respectively (of course, use only one): ``` --hwaccel_enc=VAAPI --hwaccel_enc=OMX ``` If your system supports VAAPI: * It could be possible that the rendering device on your system goes by a different name than the default "/dev/dri/renderD128". You can use the --hwaccel_enc_device parameter to set it. * Depending on what your renderer supports, setting a bitrate will fail. On my test system, for example, CQG (Constant Quantisation parameter) is the only valid rendering control mode. The driver ignores bitrate settings and accepts the qp option only. As found in libavcodec/vaapi_encode.c: Rate control mode selection: * If the user has set a mode explicitly with the rc_mode option, use it and fail if it is not available. * If an explicit QP option has been set, use CQP. * If the codec is CQ-only, use CQP. * If the QSCALE avcodec option is set, use CQP. * If bitrate and quality are both set, try QVBR. * If quality is set, try ICQ, then CQP. * If bitrate and maxrate are set and have the same value, try CBR. * If a bitrate is set, try AVBR, then VBR, then CBR. * If no bitrate is set, try ICQ, then CQP. At the moment, this is hardwired into the code. None of these values can be controlled now by the command line. This is planned, of course, but not implemented in the current version yet. ## Hardware Decoding This version has been tested with VAAPI (Debian) and MMAL (Raspberry). It may be possible that other APIs work, but this has not been confirmed yet. To enable hardware support, use these parameters respectively (of course, use only one): ``` --hwaccel_dec=VAAPI --hwaccel_dec=MMAL ``` If your system supports VAAPI: - It could be possible that the rendering device on your system goes by a different name than the default "/dev/dri/renderD128". You can use the --hwaccel_enc_device parameter to set it. On slow machines like the Raspberry, this should give an extra kick and also relieve the CPU from load. On faster machines, this impact may be smaller, yet noticeable. The decoding part is a bit tricky. If encoding is set to hardware, and this hardware is there and capable of encoding, it will work. If hardware decoding is possible, it depends on the source file. Therefore, the file needs to be checked first and then it needs to be decided if hardware acceleration can be used or if a fallback to software is required. FFmpeg requires that to be set via the command line, but FFmpegfs must be able to decide that automatically. ### TODOs Doing both de- and encoding in hardware can make costly transfers of frames between software and hardware memory unneccessary. It is not clear, at the moment, if it is possible to keep the frames in hardware as FFmpegfs does some processing with the frames (for example, rescaling or deinterlacing), which probably cannot be done without transferring buffers from hardware to software memory and vice versa. We'll see. As seen above, selecting a target bitrate turns out to be a bit tricky. I'll have to work out a way to reach the desired bitrate in any case (no matter if the hardware supports CQP, VBR, CBR, ICQ, or AVBR). On the other hand, everything seems to work and there are no show stoppers in sight. Sheesh, wiping the sweat off my chin :) HTTP Live Streaming =================== FFmpegfs supports HLS (HTTP Live Streaming). FFmpegfs will create transport stream (ts) segments and the required m3u8 playlists. For your convenience, it will also offer a virtual test.html file that can playback the segments using the hls.js library (see https://github.com/video-dev/hls.js/). To use the new HLS feature, invoke FFmpegfs with: ffmpegfs -f $HOME/test/in $HOME/test/out -o allow_other,ro,desttype=hls Please note that this will only work over http because most browsers refuse to load multimedia files from the local file system, so you need to publish the directory on a web server. Security restrictions prevent direct playback from a disk. Simply navigate to the directory and open test.html. Cue Sheets ========== Cue sheets, or cue sheet files, were first introduced for the CDRWIN CD/DVD burning software. Basically, they are used to define a CD or DVD track layout. Today, they are supported by a wide range of optical disk authoring applications and, moreover, media players. When a media file is accompanied by a cue sheet, its contents are read and a virtual directory with separate tracks is created. The cue sheet file must have the same name but the extension ".cue" instead. It can also be embedded into the media file. The directory is named after the source media, with an additional ".tracks" extension. If several media files with different extensions exist, for example, different formats, several ".tracks" directories will be visible. Example: myfile.mp4 myfile.ogv myfile.cue If the destination type is TS, the following files and directories will appear: myfile.mp4 myfile.mp4.ts myfile.ogv myfile.ogv.ts myfile.cue myfile.mp4.tracks/ myfile.ogv.tracks/ Tracks defined in the cue sheet will show up in the *.tracks subdirectories. Selecting Audio and Video Codecs ========== Some new codec combinations are now possible (the default codecs are in bold): | Formats | Audio Codecs | Video Codecs | | ------- | ----------------- | ---------------------------- | | MP4 | **AAC**, MP3 | **H264**, H265, MPEG1, MPEG2 | | WebM | **OPUS**, VORBIS | **VP9**, VP8 | | MOV | **AAC**, AC3, MP3 | **H264**, H265, MPEG1, MPEG2 | | TS, HLS | **AAC**, AC3, MP3 | **H264**, H265, MPEG1, MPEG2 | For audio, the codec can be selected with --audiocodec. For videos, use --videocodec. Without these parameters, FFmpegfs will use the codecs as before (no change). Please note that hardware acceleration might not work, e.g., my hardware encoder supports H264 but not H265. So even though H265 creates much smaller files, it takes 10 times longer to transcode. Building A Docker Container ========== FFmpegfs can run under Docker. A Dockerfile is provided to build a container for FFmpegfs. Change to the "docker" directory and run docker build --build-arg BRANCH=master -t nschlia/ffmpegfs . Depending on the machine speed, this will take quite a while. After the command is completed, the container can be started with docker run --rm \ --cgroupns host \ --name=ffmpegfs \ --device /dev/fuse \ --cap-add SYS_ADMIN \ --security-opt apparmor:unconfined \ -v /path/to/source:/src:ro \ -v /path/to/output:/dst:rshared \ nschlia/ffmpegfs \ -f --log_stderr --audiobitrate=256K -o allow_other,ro,desttype=mp3,log_maxlevel=INFO Of course, */path/to/source* must be changed to a directory with multi-media files and */path/to/output* to where the converted files should be visible. The output type may be changed to MP4 or whatever is desired. Auto Copy ========= "Auto copy" performs intelligent stream copy. For example, if transcoding a transport stream that already represents a H264 video and/or AAC audio stream, it is possible to simply repackage it to an mp4 container without recoding. This is very efficient because it does not require as much computing as de- and encoding, and it also does not degrade quality because the original file remains essentially unchanged. The function detects if the target format supports the source codec and simply remuxes the stream even if recoding from one format (for example, TS) to another (for example, MOV, MP4). There are three options: | Option | Description | | ------ | ------------------------------------------------------------ | | OFF | no auto copy. | | LIMIT | only auto copy if the target file will not become significantly larger. | | ALWAYS | auto copy whenever possible, even if the target file becomes larger. | Smart Transcoding ================= Smart transcoding can create different output formats for video and audio files. For example, video files can be converted to ProRes and audio files to AIFF. Of course, combinations like MP4/MP3 or WebM/WAV are possible but do not make sense, as MP4 or WebM work perfectly with audio-only content. To use the new feature, simply specify a video and audio file type, separated by a "+" sign. For example, *--desttype=mov+aiff* will convert video files to Apple Quicktime MOV and audio only files to AIFF. This can be handy if the results are consumed, for example, by some Apple editing software, which is very picky about the input format. *Notes* 1. The first format must be a video codec, and the second must be an audio codec. For example, *--desttype=wav+mp4* is invalid, and instead it should be *--desttype=mp4+wav*. 2. Smart transcoding currently determines the output format by taking the input format type into account, e.g., an MP3 would be recoded to AIFF, an MP4 to MOV even if the input MP4 does not contain a video stream. The input format should be scanned for streams and the output selected appropriately: An MP4 with video should be transcoded to MOV, an MP4 with audio only to AIFF. See [Issue #86] (https://github.com/nschlia/ffmpegfs/issues/86) for details. Transcoding To Frame Images ========================= To transcode a video to frame images, set the destination type to JPG, PNG, or BMP. This will convert videos into virtual folders with one image for each frame. ``` $ ls /storage/videos video1.mp4 video2.mov $ ffmpegfs /storage/videos /mnt/ffmpegfs $ find /mnt/ffmpegfs /mnt/ffmpegfs/video1.mp4/00001.png /mnt/ffmpegfs/video1.mp4/00002.png ... /mnt/ffmpegfs/video1.mov/00001.png /mnt/ffmpegfs/video1.mov/00002.png ``` A Few Words On ProRes ===================== Apple's ProRes is a so-called intermediate format, intended for post-production editing. It combines the highest possible quality while still saving some disk space and not requiring high-performance disk systems. On the other hand, this means that ProRes encoded videos will become quite large—for example, a 60-minute video may require up to 25 GB. It is not for target audience use, and certainly not suitable for internet streaming. Also, please keep in mind that when using lossy source input formats, the quality will not get better, but the files can be fed into software like Final Cut Pro, which only accepts a small number of input formats. Transcoding Subtitles ===================== Closed captions are converted to the output files, if possible. There are two general subtitle formats: text and bitmap. Subtitle transcoding is currently only possible from text to text or bitmap to bitmap. It may be relatively easy to convert text to bitmap, but not vice versa. This would require some sort of OCR and could become arbitrarily complex. That may work well for Latin alphabets, but there are others. Guess what would happen with Georgian, Indian, Chinese, or Arabic... | Output Format | Subtitle Codec | Format | | ---------------- | ------------------------------------------------------ | ------ | | MP4, MOV, ProRes | MOV Text (Apple Text Media Handler) | Text | | WebM | WebVTT Subtitles (Web Video Text Tracks Format) | Text | | TS, HLS | DVB Subtitles | Bitmap | | MKV | ASS (Advanced SSA), SubRip Subtitles, WebVTT Subtitles | Text | | MKV | DVB Subtitles | Bitmap | Matroska (MKV) supports a wide range of subtitle formats, both text and bitmap. FFmpegfs automatically selects the best matching output codec. MKV would be the best choice to cover all input subtitle formats. ## External Subtitle Files Subtitles can reside in separate files. These must have the same filename but the extension "srt" for ASS/SubRip or "vtt" for WebVTT. The language can be defined with a second level extension, e.g. "mediafile.en.srt" would define the contents as "English". There is no convention for the language name, so it could even be the full language name like "mediafile.french.srt" or similar. Example | Filename | Contents | | -------------- | -------------------------- | | myvideo.mkv | Video | | myvideo.de.srt | German Subtitles | | myvideo.en.srt | English Subtitles | | myvideo.es.srt | Spanish Subtitles | | myvideo.fr.srt | French Subtitles | | myvideo.hu.srt | Hungarian Subtitles | | myvideo.it.srt | Italian Subtitles | | myvideo.jp.srt | Japanese Subtitles | | myvideo.srt | Unknown Language Subtitles | **TODO:** * Maybe FFmpeg could convert text to bitmap for TS/HLS if the input format is not bitmapped. MP4 Format Profiles ================== The MP4 container has several derivative formats that are not compatible with all target audiences. To successfully feed the resulting files into, for example, MS Edge, the subformat must be different than for Firefox, unfortunately. The --profile option allows you to select the format. | Profile | OS | Target | Remarks | | ------- | --------------------- | ------------------------------ | ------------------------------ | | NONE | all | VLC, Windows Media Player etc. | Playback (default) | | FF | Linux, Win10, Android | Firefox | OK: Playback while transcoding | | | Win7 | Firefox | OK: Playback while transcoding | | EDGE | Win10 | MS Edge, IE > 11 | OK: Playback while transcoding | | | Win10 Mobile | | OK: Playback while transcoding | | IE | Win10 | MS IE <= 11 | OK: Playback while transcoding | | | Win7 | | Must decode first (1) | | CHROME | all | Google Chrome | Must decode first (1) | | SAFARI | Win | Apple Safari | Must decode first (1) | | OPERA | All | Opera | Must decode first (1) | | MAXTHON | Win | Maxthon | Must decode first (1) | (1) * An error message appears when the file is opened while transcoding. * Must start again when the file is transcoded. * It works fine when the file is loaded directly from the buffer. This all boils down to the fact that Firefox and Edge are the only browsers that support the necessary extensions to start playback while still transcoding. In most cases, files will not play if they are not properly optimised. ffmpegfs-2.50/TODO0000644000175000017500000000044715052412650007413 FFmpegfs TODOs ============== * I'll have many more ideas when I wake up and find them nice to have. * Any additional features that you may desire. * I am working on a Windows version. * DASH support is on my list, but the format is complicated and I currently do not have the time for that.  ffmpegfs-2.50/configure.ac0000664000175000017500000002330715215723104011213 # Process this file with autoconf to produce a configure script. # Sets up package and initializes build system.

That means, when there is a problem accessing a file, copying or opening it, you will get an "Invalid argument" or "Operation not permitted". Not really informative. There is no way to pass the original result code through the file system. What you will have to do is refer to the syslog, system journal, or to the FFmpeg log itself, optionally at a higher verbosity. If you are unable to resolve the problem yourself, feel free to create [an issue](https://github.com/nschlia/ffmpegfs/issues), stating what you have done and what has happened. Do not forget to add logs (preferably at a higher verbosity) and, if possible, a description of how to recreate the issue. It would also be helpful to have an example of the media file that is generating the error. Copyrighted material should never be sent, nevertheless. ## Transcoding too slow Slow transcoding can be caused by a variety of factors, including a slow CPU or network issues. This might help with decoding and encoding speed: [Building FFmpeg with optimisations](INSTALL.md#building-ffmpeg-with-optimisations). ## Lock ups when accessed through Samba When accessed from a Samba drive, the pending read can lock the whole share, causing Windows Explorer and even KDE Dolphin to freeze. Any access from the same machine to that share is blocked. Even "ls" is not possible and blocks until the data is returned. It seems others had the same problem: http://samba.2283325.n4.nabble.com/Hangs-Accessing-fuse-filesystem-in-Windows-through-Samba-td4681904.html Adding this to the [global] config in smb.conf fixes that: oplocks = no level2 oplocks = no aio read size = 1 The "aio read size" parameter may be moved to the share config: aio read size = 1 ## rsync, Beyond Compare and other tools Some copy tools do not get along very well with dynamically generated files, as in [Issue #23: Partial transcode of some files](https://github.com/nschlia/ffmpegfs/issues/22). Under Linux, it is best to use (optionally with the -r parameter) cp -upv /path/to/source /path/to/target This will copy all missing or changed files without missing parts. On the Windows side, Windows Explorer or copy/xcopy work. Beyond Compare and comparable tools might only duplicate the expected size without responding to changes in size. Please take note of the "-p" parameter, which means "—preserve=mode,ownership,timestamps." It appears that files may occasionally be copied with zero size if it is absent. ## Open hls.html from disk to play HLS output. The majority of browsers forbid playing back files from disc. You may put them into a website directory, however sometimes https must be used in order to allow playback. **To enable disk playback in Firefox:** - Open about:config - Set security.fileuri.strict_origin_policy to false. ## Songs get cut short If you are using SAMBA or NFS and songs don't play all the way through, you're in trouble. It occurs when files are transcoded live, but never when a file is retrieved from cache. This is because the final size seldom comes out exactly as expected. Size information is only available up front when a cached file is returned. If the outcome is smaller than expected, SAMBA fills files with zeros; if the outcome is larger than expected, SAMBA chops off the remaining data. Unlike SAMBA, NFS sends either the right file or one that has been chopped or padded randomly. You can do this as many times as you like, with a different result each time. There doesn't appear to be a solution to that as of now. Perhaps NFS or SAMBA can be set up to handle that, but I'm not sure how. ffmpegfs-2.50/HISTORY.md0000664000175000017500000007336415215723104010420 History ======= ### New in 2.50 (2026-06-12): - **Bugfix:** Fixed audio/video synchronization issues during transcoding. - **Bugfix:** Fixed HLS playback stopping unexpectedly, especially near the final segment. - Refactored FFmpeg resource handling to use RAII wrappers for AVPacket, AVFormatContext, AVAudioFifo, AVDictionary, SwrContext, and SwsContext. - Removed deprecated av_init_packet() usage and switched packet handling to allocation-based AVPacket lifetime management. - Improved cleanup of FFmpeg input/output contexts, including custom AVIOContext handling and error paths during context allocation. - Improved audio FIFO, resampler, scaler, and dictionary lifetime management to reduce manual cleanup code and avoid leaks on error paths. - Cleaned up transcoder shutdown paths by centralizing FFmpeg resource cleanup in dedicated wrapper classes. - **Bugfix:** Fixed retained FFmpeg deinterlace filter graphs when the output pipeline is rebuilt, especially after HLS seeks. Old filter graphs are now released before reinitialisation and when closing the current output, preventing stale filter pointers and retained filter buffers. - **Bugfix:** Fixed HLS playback stopping unexpectedly, especially near the last HLS segment. - **Bugfix:** Improved HLS segment finalisation and state cleanup between segment transitions. - **Bugfix:** Improved packet/frame lifetime handling to avoid stale state during HLS playback. - Added a `make help` target to list the available build, test, installation, documentation and maintenance targets. - Added `./configure --enable-perftools` to build ffmpegfs with Google Perftools heap profiling support. - **Bugfix:** Fixed HLS playback for 10-bit UHD/HDR sources by converting H.264 HLS output to yuv420p/8-bit. This avoids unsupported H.264 High10 streams in browser-based players such as hls.js. - Added elapsed-time reporting to successful transcode completion messages, showing the total transcoding time in milliseconds. - **Bugfix:** Fixed a race condition in transcoder thread start-up which could allow the same cache entry to be transcoded more than once concurrently. - Consolidated transcoder completion logging so each worker now emits one clear final status message, including elapsed runtime for successful transcodes. - **Bugfix:** Fixed HLS cache recovery so stale segment metadata no longer leaves playback waiting indefinitely when the corresponding cache file is missing, empty, or otherwise unusable. - Improved HLS segment recovery by explicitly restarting the transcoder when a segment is marked as available but its cache file is missing, empty, or otherwise unusable. - **Bugfix:** Fixed HLS segment availability checks so incomplete cache entries no longer make segments appear available when those segments were never actually produced. - Added additional safeguards for stale decoder state to avoid leaving cache entries permanently marked as decoding when no active worker is available to repair them. - **Bugfix:** Ignored HLS seek requests that are too close to the beginning of a stream so transcoding starts at segment 1 instead of creating an avoidable partial cache set. - Added an HLS cache regression test that pre-populates the cache, re-reads all generated segments, and verifies that cached segment output remains stable across repeated reads. - **Bugfix:** Fixed HLS cache test log naming so wrapper scripts which already contain the `_hls` suffix no longer generate duplicate `_hls_hls` builtin log files. - **Bugfix:** Fixed `distclean`/`distcheck` failures caused by incorrectly named HLS test log files being left behind in the test build directory. - Refactored transcoder stream and output initialisation into smaller helper functions, making the setup flow easier to maintain. - Improved `AVCodecContext` ownership handling during stream, output, and frame-set setup so failed initialisation paths no longer leak codec contexts. - Hardened output/cache setup with additional validation and null checks to avoid partially initialised stream state and provide clearer error handling. - Improved duration metadata handling for stream-copy and album-art output so invalid or missing input timing information is no longer used. - Improved test cleanup by using explicit ffmpegfs-owned temporary directory names and guarded removal logic, avoiding stale anonymous `/tmp` directories after interrupted or parallel test runs. - Improved deinterlacing quality by replacing `yadif` with `bwdif` while keeping one output frame per input frame. This improves playback smoothness for interlaced sources without changing the output frame rate or requiring changes to timestamp, FPS, or HLS segment timing logic. ### New in 2.18 (2026-04-10): - **Feature:** Added ALAC profile for iTunes (`--desttype=ALAC --profile=ITUNES`). Playback of the file will not commence until it is fully recoded; however, it can be played in iTunes. - **Feature:** Implemented a validation check for the combination of TYPE and PROFILE in `--desttype=TYPE --profile=PROFILE`. - Updated Dockerfile to include FUSE 3. - **Bugfix:** Fix error with new FFmpeg API: *"Option 'pix_fmts' is not a runtime option and so cannot be set after the object has been initialized"*. - **Fixed deprecation:** Replace `avcodec_get_supported_config()`. - **Fixed deprecation:** Remove `avcodec_close()`. - **Fixed deprecation:** Remove `av_format_inject_global_side_data()`. - **Fixed deprecation:** Replace `std::codecvt` with `iconv` in `read_file`. - **Bugfix:** `reserve()` only guarantees capacity, not size → writing via `.data()` is undefined behaviour. Using `resize()` makes the memory usable. - As `strerror()` is not thread-safe, use `strerror_r()` where available. - `strncpy` likes to copy without NUL → terminate explicitly. - **Bugfix:** Issue [#173](https://github.com/nschlia/ffmpegfs/issues/173): Fixed output directory no showing complete list of files under Debian 13. - **Bugfix:** Updated Dockerfile for Trixie - **Bugfix:** Closes [#1115015](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1115015): Fix build with FFmpeg 8 (already applied in Debian via NMU) - **Bugfix:** Closes [#1119414](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1119414) Changed configure.ac and makefile.am to preserve the default build flags **New in 2.17 (2024-11-10):** - **Bugfix:** Issue [#164](https://github.com/nschlia/ffmpegfs/issues/164): Fixed incorrectly discarded HLS seek requests. - **Bugfix:** Wrong error message fixed when an invalid audio/video codec was selected. The message should rather say "unsupported codec" instead of talking about "sample format not supported.". - **Bugfix:** Issue [#162](https://github.com/nschlia/ffmpegfs/issues/162): If not present, add time stamps to the copied streams. - Changed quality from 34 to 40 for hardware encoded video streams to create slightly smaller files. - [Closes#1084487:](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1084487): Moved from the Fuse 2 to the Fuse 3 API. **New in 2.16 (2024-06-10):** - **Bugfix:** Issue [#160](https://github.com/nschlia/ffmpegfs/issues/160): Fix build with FFmpeg 7.0. [Debian Bug #1072412](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1072412). write_packet() now with const buffer as of Libavformat 61+. - Fixed deprecation: 2014-05-18 - 68c0518 / fd05602 - lavc 55.63.100 / 55.52.0 - avcodec.h Add avcodec_free_context(). From now on it should be used for freeing AVCodecContext. - Fixed deprecation: 2023-05-15 - 7d1d61cc5f5 - lavc 60 - avcodec.h Depreate AVCodecContext.ticks_per_frame in favor of AVCodecContext.framerate (encoding) and AV_CODEC_PROP_FIELDS (decoding). **New in 2.15 (2024-02-03):** - **Bugfix:** Issue [#151](https://github.com/nschlia/ffmpegfs/issues/151): Fixed autocopy STRICT never triggers for video streams - **Bugfix:** Issue [#153](https://github.com/nschlia/ffmpegfs/issues/153): The --include_extensions parameter now contains a description, which was previously missing from the manual and online help. - **Issue** [#149](https://github.com/nschlia/ffmpegfs/issues/149): 2023-05-04 - xxxxxxxxxx - lavu 58.7.100 - frame.h Deprecate AVFrame.interlaced_frame, AVFrame.top_field_first, and AVFrame.key_frame. Add AV_FRAME_FLAG_INTERLACED, AV_FRAME_FLAG_TOP_FIELD_FIRST, and AV_FRAME_FLAG_KEY flags as replacement. - **Issue** [#149](https://github.com/nschlia/ffmpegfs/issues/149): 2023-05-04 - xxxxxxxxxx - lavu 58.7.100 - frame.h Deprecate AVFrame.interlaced_frame, AVFrame.top_field_first, and AVFrame.key_frame. Add AV_FRAME_FLAG_INTERLACED, AV_FRAME_FLAG_TOP_FIELD_FIRST, and AV_FRAME_FLAG_KEY flags as replacement. - **Issue** [#149](https://github.com/nschlia/ffmpegfs/issues/149): 2021-09-20 - dd846bc4a91 - lavc 59.8.100 - avcodec.h codec.h Deprecate AV_CODEC_FLAG_TRUNCATED and AV_CODEC_CAP_TRUNCATED, as they are redundant with parsers. - Issue [#136](https://github.com/nschlia/ffmpegfs/issues/136): The CMake build files have been removed. Support was never more than experimental, and CMake lacks a good uninstall option. Will stick to automake system from now on. **New in 2.14 (2023-06-15):** - **Bugfix:** Issue [#141](https://github.com/nschlia/ffmpegfs/issues/141): Improved memory management by allocating several times the average size of allocations. This prevents obtaining tiny portions over and over again. Additionally, after the file is opened, grab the entire expected memory block rather than doing a tiny allocation initially, followed by a larger allocation. - **Bugfix:** Avoid race conditions that cause the inter-process semaphore creation to fail for the second process. - **Bugfix:** Issue [#119](https://github.com/nschlia/ffmpegfs/issues/119): If a seek request is still open after EOF, restart transcoding. - **Bugfix:** Issue [#119](https://github.com/nschlia/ffmpegfs/issues/119): To prevent frame/segment creation errors, the frame set and HLS code has been updated. - **Bugfix:** Avoid crashes during shutdown if cache objects have already been closed. - **Bugfix:** Issue [#119](https://github.com/nschlia/ffmpegfs/issues/119): The AVSEEK_FLAG_FRAME set should be used to seek to frames when building frame sets. Otherwise, output images may vary if searched for or continuously decoded. - **Bugfix:** The conversion of PTS to frame number and vice versa for frame sets was incorrect if TBR did not equal frames per second. - **Bugfix:** Fixed seek requests that are being ignored with frame sets. - **Bugfix:** When transferring from cache to the Fuse buffer, avoid a possible 1 byte overrun. - **Bugfix:** Issue [#143](https://github.com/nschlia/ffmpegfs/issues/143): To avoid occasional EPERM failures, missing synchronisation objects were added. - **Bugfix:** Issue [#144](https://github.com/nschlia/ffmpegfs/issues/144): To fix the crashes that may have been caused by them, the variables impacted by a potential threading issue were marked as "volatile." - **Bugfix:** [Closes#1037653:](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1037653) Fix build with GCC-13 - **Bugfix:** Update docker build for Debian Bookworm - **Enhancement:** Record milliseconds for every log event. - **Enhancement:** make check: added a file size check to frame set tests. - **Optimisation:** When reopening after invalidating the cache, the size remained at 0. The original size is now once again reserved in order to prevent reallocations. - **Optimisation:** To avoid reallocations, save enough space in the cache buffer to hold the entire frame set. - **Optimisation:** Checking folders to see if they can be transcoded is completely pointless. Directories are now immediately skipped. - To avoid problems with logfile viewers, renamed built-in logfiles to *_builtin.log (removing the double extension). **New in 2.13 (2023-01-15):** - **Feature:** Added --prebuffer_time parameter. Files will be decoded until the buffer contains the specified playing time, allowing playback to start smoothly without lags. Works similar to --prebuffer_size but gives better control because it does not depend on the bit rate. An example: when set to 25 seconds for HLS transcoding, this will make sure that at least 2 complete segments will be available once the file is released and visible. - **Feature:** Issue [#140](https://github.com/nschlia/ffmpegfs/issues/140): Filtering the files that will be encoded has been added. A comma-separated list of extensions is specified by the *—include_extensions* parameter. These file extensions are the only ones that will be transcoded. The entries support shell wildcard patterns. - **Feature:** The --hide_extensions parameter syntax has been extended. The entries now support shell wildcard patterns. - **Bugfix:** Issue [#139](https://github.com/nschlia/ffmpegfs/issues/139): Additional files could be added using the *—extensions* parameter. However, this is no longer necessary; in the past, a file's extension determined whether or not it would be transcoded. Files with unknown extensions would be ignored. The extension is no longer important because FFmpegfs now examines all input files and recognises transcodable files by the format. The outdated *—extensions* argument was removed without substitution. - **Bugfix:** Fixed crash when implode() function was called with an empty string. Happened with Windows GCC 11.3.0 only. ### Version 2.12 released **New in 2.12 (2022-08-27):** - The code has been run through clang-tidy to detect areas that could be updated to C++17 and to find areas that are prone to bugs or are inefficient. Many problems could be fixed. Sometimes a few lines of code can take the place of many. Some components function far more effectively than they did in the past. C++17 is cool! I must purchase a t-shirt. - **Bugfix:** In get prores bitrate(), a crash that might have happened under unusual circumstances has been corrected. If the best match resolution could not be found, array access out-of-bounds could happen. - **Bugfix:** Several unlikely, but potential problems that could have happened when subtitle decoding failed or delayed video/audio packets couldn't be decoded have been fixed. - **Bugfix:** An internal problem could cause the application to crash. Should never happen, though. Fixed anyway. - **Bugfix:** Sometimes, the last segment's estimated size was incredibly small - about 2 bytes. Each segment should have the same predicted size as is is calculated simply by dividing the projected size of the entire file by the number of segments. Following transcoding, the size was accurate. ### Version 2.11 released **New in 2.11 (2022-06-16):** * **Feature:** [Issue #86](https://github.com/nschlia/ffmpegfs/issues/86): Smart transcode now detects if a source file is audio only and uses the correct target format. For example, with --destination=webm+mp3, if one MP4 input file contains a video stream and another an audio stream only, the resulting files will be WebM (for the video input) and mp3 for the audio only file. * **Feature:** [Issue #137](https://github.com/nschlia/ffmpegfs/issues/137): Add --no_subtitles option to turn subtitles off. * **Bugfix:** Smart encode selected the video format for cue sheet tracks, regardless of the input format. This has been fixed now. * **Bugfix:** Fix a crash that occurs when a DVD/Blu-ray is transcoded to audio only. * **Bugfix:** If the track performer field in the cuesheet is blank, try album performer instead. * **Bugfix:** Failing to mount Fuse during "make check" went unnoticed as the result code (which was supposed to be 99) was actually 0. Return the correct result code, failing the operation as expected. * **Bugfix:** The Docker build command contained a "make check" which actually failed altogether. Step has been removed. "make check" mounts Fuse, but this requires privileges that do not exist during "docker build". * **Bugfix:** On error, mremap () returns MAP_FAILED rather than NULL. Fixed a check for incorrect error conditions, which could cause the application to crash or return illogical error messages. * **Bugfix:** [Issue #119](https://github.com/nschlia/ffmpegfs/issues/119): Fix a problem that caused frame set generation to fail sometimes. It seems to be related to the nremap() issue. * Generally revisited documentation, logging, and display texts. Improved grammar, formatting, and fixed quite a few typos that escaped all proofreading sessions. * The FFmpeg API INFO and DEBUG level log output has been changed to the FFmpegfs DEBUG level. What FFmpeg considers "INFO" is far too chatty. * Frequent memory reallocations when creating HLS segments have been reduced to speed up processing. * Optimised logging to save CPU time by not formatting log entries that are not written anyway at their log level. * Logging has been revised to shorten file paths and remove mount, input, and cache paths. Log the additional portion only to reduce log file size and improve readability. * **Bugfix:** To fix the build with GCC 12, add the missing include headers (closes: [#1012925](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1012925)). ### Version 2.10 released **New in 2.10 (2022-04-26):** * **Feature:** [Issue #123](https://github.com/nschlia/ffmpegfs/issues/123): New command line option to hide files by extension. Example: `--hide_extensions=jpg,png,cue` would stop covers and cue sheets from showing up. * **Feature:** [Issue #120](https://github.com/nschlia/ffmpegfs/issues/120): Added subtitle support. Subtitle streams can now also be transcoded to the output files. Separate SRT or VTT files will be incorporated as subtitle streams. * **Bugfix:** Fixed memory leak in encode_audio_frame(). * **Bugfix:** [Issue #122](https://github.com/nschlia/ffmpegfs/issues/122): Last song was missing from cuesheet files. * **Bugfix:** [Issue #129](https://github.com/nschlia/ffmpegfs/issues/129): Files remained zero size when previously transcoded. * **Bugfix:** [Issue #130](https://github.com/nschlia/ffmpegfs/issues/130): Fix file sizes can be incorrectly reported by ls but are correct when data is read. * **Bugfix:** Duration was not saved in cache SQLite database. * **Bugfix:** [Issue #131](https://github.com/nschlia/ffmpegfs/issues/131): Sometimes video parameters for some Blu-ray or DVD chapters cannot be detected by FFmpeg API. Transcode then fails - fixed by using data from the Blu-ray directory or DVD IFO instead. * Lowest supported FFmpeg API version raised to 4.1.8 "al-Khwarizmi". * Dropped libavresample support, library was removed from FFmpeg API after 3.4.9. * Deprecated previous channel layout API based on uint64 bitmasks. * Deprecated swr_alloc_set_opts() and swr_build_matrix(). * Going C++17 now: The packet queue has been recoded in C++17 to support external subtitles files. As C++17 is required now, why not go all the way: Starting to replace legacy C++ and somewhat C-like parts with real C++. * Using std::shared_ptr to ensure proper memory allocation/free. ### Version 2.9 released **New in 2.9 (2022-02-16):** * **Feature:** [Issue #97](https://github.com/nschlia/ffmpegfs/issues/97): Added options to chose different codecs. The audio codec can be selected with --audiocodec, for videos use --videocodec. * **Feature:** [Issue #109](https://github.com/nschlia/ffmpegfs/issues/109): Allow user defined file extensions for source files. By default, only standard extensions are accepted, i.e., mp4, ts, avi etc. Arbitrary file extensions can be defined now, e.g. using --extensions=xxx,abc,yxz,aaa to also convert files ending with .xxx, .abc and so on. * **Feature:** [Issue #121](https://github.com/nschlia/ffmpegfs/issues/121): Added MKV support. New format can be selected with --desttype=mkv. * **Bugfix:** [Issue #112](https://github.com/nschlia/ffmpegfs/issues/112): Fixed Docker detection. * **Bugfix:** [Issue #110](https://github.com/nschlia/ffmpegfs/issues/110): Docker build command failed, added missing libchardet and allow libdvdread4 or *8 to be used, whatever available. * **Bugfix:** Fixed crash when video had no audio. * **Bugfix:** [Issue #112](https://github.com/nschlia/ffmpegfs/issues/112): Fixed access problems with frame sets and HLS. * **Bugfix:** Issue #119: Fixed problem that caused frame set generation to sometimes fail. * **Bugfix:** Fixed JPG frame set generation. Suddenly FF_COMPLIANCE_UNOFFICIAL was required to have FFmpeg API accept the codec. * **Enhancement:** [Issue #67](https://github.com/nschlia/ffmpegfs/issues/67): Enhanced file size prediction. * **Bugfix:** Need to synchronise screen log. Concurrent entries by separate threads produced garbled output. * **Bugfix:** Avoid creating an HLS segment number which is out of bounds (higher than the expected number of segments). * **Bugfix:** Removed QMake support, replaced with CMake. ### Version 2.8 released **New in 2.8 (2021-11-29):** * **Bugfix:** [Issue #102](https://github.com/nschlia/ffmpegfs/issues/102): Not all SQL queries where case sensitive, causing cache confusion. Several database entries were created, but only one was updated. Made all queries case sensitive. * **Bugfix:** [Issue #91](https://github.com/nschlia/ffmpegfs/issues/91): Fixed HLS problems with cache causing garbled videos and hick-ups in audio. * **Enhancement**: [Issue #103](https://github.com/nschlia/ffmpegfs/issues/103): If requested HLS segment is less than X (adjustable) seconds away, discard seek request. Segment would be available very soon anyway, and that seek makes a re-transcode necessary. Can be set with *--min_seek_time_diff*. Defaults to 30 seconds. * **Feature**: [Issue #105](https://github.com/nschlia/ffmpegfs/issues/105): Added Free Lossless Audio Codec (FLAC) support. Activate with *--desttype=FLAC*. * **Feature:** [Issue #101](https://github.com/nschlia/ffmpegfs/issues/101): Sample format for audio files can be selected via command line with *--audiosamplefmt*. Possible values are 0 to use the predefined setting, 8, 16, 32, 64 for integer format, F16, F32, F64 for floating point. Not all formats are supported by all destination types, selecting an invalid format will be reported as error and a list of values printed. Defaults to 0 (Use same as source or the predefined format of the destination if source format is not possible). ### Version 2.7 released **New in 2.7 (2021-11-08):** * **Bugfix:** [Issue #92](https://github.com/nschlia/ffmpegfs/issues/92): Fixed crash when hardware decoding failed. The problem is that the FFmpeg API very late reports that it cannot decode the file in hardware. To find out about that, the source file must be decoded until the first video frame is encountered. It would be very time consuming to do this on every file (decode until it is clear that the file is supported, then actually start transcoding it from scratch). There is no feasible way to automatically handle the situation. To get around this a --hwaccel_dec_blocked parameter has been added. If hardware decoding fails, check the log for a message similar this: "[vp9 @ 0x7fe910016080] No support for codec vp9 profile 0." If VP9 profile 0 is not supported, the parameter would be: --hwaccel_dec_blocked=VP9:0 This will tell FFmpegfs to decode the file in software. To block VP9 as a whole, the parameter would be --hwaccel_dec_blocked=VP9. To block both profile 0 and 1, use --hwaccel_dec_blocked=VP9:0:1. The parameter can be repeated to block even more codecs. * **Bugfix:** [Issue #96](https://github.com/nschlia/ffmpegfs/issues/96): Fixed potential buffer overrun and crash when reading corrupted input files. * **Enhancement:** [Issue #99](https://github.com/nschlia/ffmpegfs/issues/99): Report command line error if --desttype specifies audio format first, or if the second format is not audio only. Avoid misinterpretations. For example, --desttype=aiff+mov would create MOV files out of any input. Correct would be --desttype=mov+aiff which will create MOV files out of videos and AIFF from audio files, as expected. ### Version 2.6 released **New in 2.6 (2021-09-04):** * No new features, just a bugfix. See V2.4 for details. ### Version 2.5 released **New in 2.5 (2021-06-18):** * **Feature**: [Issue #63](https://github.com/nschlia/ffmpegfs/issues/63) - Hardware acceleration for encoding/decoding is partly implemented, VAAPI/MMAL/OMX/V4L2 are currently available only. - Supported hardware: V4L2/VAAPI (Intel) and V4L2/MMAL/OMX (Raspberry). - VAAPI: H264, H265/HEVC, MPEG-2 and VP-8 decoding and H264 encoding. - VAAPI: MJPEG and VC-9 do not work (yet). - MMAL: H264, MPEG-2, MPEG-4 and VC1 decoding. - OMX: H264 encoding. - V4L2: H263, H264, H265, MPEG1/2/4, VC-1, VP8/9 encoding/decoding. * **Feature**: Added unit tests for hardware acceleration. Failing tests will report as *SKIPPED* and not fail the whole test. * **Note**: Which hardware en/decoder actually works depends on what your hardware supports. * **Call for testers**: Have a CUDA capable graphics adapter and interested in testing? Please write me an e-mail. ### Version 2.4 released **New in 2.4 (2021-09-04):** * **Bugfix:** [Issue #90](https://github.com/nschlia/ffmpegfs/issues/90): Make sure that one keyframe gets inserted at the start of each HLS segment. ### Version 2.3 released **New in 2.3 (2021-06-11):** * **Enhancement:** [Issue #80](https://github.com/nschlia/ffmpegfs/issues/80): Open input video codec only if target supports video. Saves resources: no need to decode video frames if not used. * **Enhancement:** [Issue #81](https://github.com/nschlia/ffmpegfs/issues/81): If source format has no audio, and the target supports no video (e.g.WAV/MP3), the files have shown up zero sized. These will now not be visible when doing ls. When trying to open them "File not found" will be returned. * **Added** "configure --enable-debug" to create binaries with debug symbols. Defaults to the optimised version. * **Feature:** [Issue #73](https://github.com/nschlia/ffmpegfs/issues/73) Cue sheet tracks now play "gapless" if played in order. Whenever a track is started, the next track will automatically be transcoded as well. * **Feature:** [Issue #66](https://github.com/nschlia/ffmpegfs/issues/66) and [issue #82](https://github.com/nschlia/ffmpegfs/issues/82): Added cue sheet support. If a file with cue extension is found with the same name as a media file or if a cue sheet is embedded into it (a tag named CUESHEET), tracks defined in it will show up in a virtual directory. * **Feature:** [Issue #83](https://github.com/nschlia/ffmpegfs/issues/83): Character conversion for cue sheet files. Automatically detects the character encoding of the cue sheet. and converts as necessary. * **Feature:** [Issue #78](https://github.com/nschlia/ffmpegfs/issues/78): Duplicate ARTIST to ALBUMARTIST tag if empty. * **Feature:** [Issue #79](https://github.com/nschlia/ffmpegfs/issues/79): Added Docker support. See [Build A Docker Container](FEATURES.md#build-a-docker-container) how to use it. * **Fixed deprecation:** 2021-03-17 - f7db77bd87 - lavc 58.133.100 - codec.h Deprecated av_init_packet() * **Fixed API compatitibility:** Many pointers made const as of 2021-04-27. Although reasonable, this breaks API compatibility with versions older than 59.0.100, * **Bugfix:** find_original "fallback" method did not correctly handle the new filename format (extension added, not the original one replaced). * **Bugfix:** [Issue #87](https://github.com/nschlia/ffmpegfs/issues/87): Segments are now properly separated, making sure that e.g. segment 3 only goes from 30 seconds up to 40 (including 30, but not 40 seconds). * **Bugfix:** [Issue #88](https://github.com/nschlia/ffmpegfs/issues/88): HLS audio and video now stay in sync after longer playback (more than 30 minutes) or after seek operations. ### Version 2.2 released **New in 2.2 (2021-02-06):** * **Note**: This is planned as a maintenance version, no new features but bug fixes only. * **Bugfix:** [Issue #75](https://github.com/nschlia/ffmpegfs/issues/75): Fix crash when opening mp3 output with Dolphin. * **Bugfix**: Possible crash in transcoder_thread: Decoder object could have been used after being freed. * **Bugfix:** Stupid blooper. WAV and AIFF size was always calculated for a mono file, thus for stereo files only half the correct size. * **Bugfix:** [Issue #70](https://github.com/nschlia/ffmpegfs/issues/70): Possible crash in Buffer::init: Should not assert if duration is 0 (and thus segment count 0). Report internal error and go on. * **Bugfix:** [Issue #70](https://github.com/nschlia/ffmpegfs/issues/70): Do not set duration to 0 from cache but leave unchanged. Caused HLS transcoding to fail if more than one transcoder was concurrently started. * **Bugfix:** Corrected documentation, "make checks" should read "make check", funny this went unnoticed for over 3 years... * **Bugfix:** [Issue #74](https://github.com/nschlia/ffmpegfs/issues/74): Album arts were only copied from MP3/4 sources. Removed restriction, if the input file contains an album art it will be copied to the target (if supported, of course, e.g., to mp3 or mp4. Ogg is not yet supported because embedding album arts in Ogg can only be done by an unofficial workaround). * **Bugfix:** [Issue #71](https://github.com/nschlia/ffmpegfs/issues/71): Virtual directories were missing dot and dot-dot nodes. ### Version 2.1 released **New in 2.1 (2020-12-14):** * **Feature**: Add BLURAY_VIDEO_FORMAT_2160P (UHD) * **Feature**: Implemented in 1.7, removed experimental state for --win_smb_fix now. Windows seems to access the files on Samba drives starting at the last 64K segment simply when the file is opened. Setting --win_smb_fix=1 will ignore these attempts (not decode the file up to this point). * **Feature**: --win_smb_fix now defaults to 1 (fix on by default). Has no effect if the drive is accessed directly or via Samba from Linux. * **Bugfix**: Fixed grammatical error in text: It's "access to", not "access at". * **Bugfix**: Did not transcode some source files with invalid DTS. * **Bugfix**: Cosmetical - No need to log date/time twice in syslog. * **Bugfix**: Cosmetical - Fix man page/online help for --recodesame parameter. * **Bugfix**: Report correct segment duration * **Bugfix**: Avoid crash if opening next HLS segment failed. Should not ignore this, but report it instead and stop transcoding. * **Cosmetical**: Log cache close action at trace level * **Cosmetical**: Shorter log entry when opening cache files ffmpegfs-2.50/INSTALL.md0000664000175000017500000003106315175426212010360 Installation Instructions for FFmpegfs ====================================== Installation from the repository -------------------------------- ### Debian Bullseye FFmpegfs has been added to Debian 11 Bullseye so it is available as a binary distribution. **On Debian 11 Bullseye, you get V2.2 by simply doing** apt-get install ffmpegfs Newer FFmpegfs versions can be installed on Debian 11 Bullseye from Bullseye Backports and sid (which is not recommended and therefore not described here). To enable Bullseye Backports: echo "deb http://deb.debian.org/debian bullseye-backports main" | sudo tee /etc/apt/sources.list.d/backports.list sudo apt-get update To install FFmpegfs from backports, run `apt-get install ffmpegfs/bullseye-backports` or `apt-get install -t bullseye-backports ffmpegfs`. **For Ubuntu 20.04 or newer and Linux distributions based on it this is** apt-get install ffmpegfs ### Debian Buster FFmpegfs can be installed on Debian 10 Buster from Buster Backports and sid (which is not recommended and therefore not described here). To enable Buster Backports: echo "deb http://deb.debian.org/debian buster-backports main" | sudo tee /etc/apt/sources.list.d/backports.list sudo apt-get update Then install FFmpegfs: sudo apt-get -t buster-backports install ffmpegfs ### Other Distributions For Arch Linux and Manjaro, it can be found in the Arch User Repository (AUR). It is available as either the latest stable version or the latest code from GIT. Building FFmpegfs yourself -------------------------- ### Prerequisites For encoding and decoding, FFmpegfs utilises the FFmpeg multi media framework. The following libraries are necessary: * gcc and g++ compilers * fuse3 (>= 3.4.1) * sqlite3 (>= 3.7.13) FFmpeg 4.1.8 "al-Khwarizmi" or newer: * libavutil (>= 56.22.100) * libavcodec (>= 58.35.100) * libavformat (>= 58.20.100) * libavfilter (>= 7.40.101) * libswscale (>= 5.3.100) * libswresample (>= 3.3.100) For optional DVD support, you need the following libraries: * libdvdread (>= 5.0.0) * libdvdnav (>= 5.0.0) For optional Blu-ray support, you need the following libraries: * libbluray (>= 0.6.2) The commands to only install the first set of prerequisites come next. For more information, see the "Supported Linux Distributions" chapter in README.md. **On Debian:** apt-get install gcc g++ make pkg-config asciidoc-base w3m xxd apt-get install fuse3 libfuse3-dev libsqlite3-dev libavcodec-dev libavformat-dev libswresample-dev libavutil-dev libswscale-dev libavfilter-dev libcue-dev libchardet-dev To get DVD support: apt-get install libdvdread-dev libdvdnav-dev To get Blu-ray support: apt-get install libbluray-dev To use "make doxy" (build Doxygen documentation): apt-get install doxygen graphviz curl To use "make check" (run test suite): apt-get install libchromaprint-dev bc **On Suse** (please read notes before continuing): zypper install gcc gcc-c++ zypper install fuse3-devel libsqlite3-devel libavcodec-devel libavformat-devel libswresample-devel libavutil-devel libswscale-devel libcue-devel libchardet-devel To get DVD support: zypper install libdvdread-devel libdvdnav-devel To get Blu-ray support: zypper install libbluray-devel Suse includes non-proprietary codecs with FFmpeg only, namely mp3, AAC and H264 are *not* available which renders this library next to usesless. But FFmpeg can be built from source, see https://trac.ffmpeg.org/wiki/CompilationGuide and check "FFmpeg compile notes" below. **On Red Hat:** yum install gcc g++ yum install fuse3-devel sqlite-devel libcue-devel libchardet-devel To get DVD support: yum install libdvdread-devel libdvdnav-devel To get Blu-ray support: yum install libbluray-devel FFmpeg is not provided by Red Hat from its repositories. It must be built from source code. See this guide: https://trac.ffmpeg.org/wiki/CompilationGuide/Centos If you want to build the documentation, you will find "asciidoc" missing from the Red Hat repositories. To get it, use a beta repository: yum --enablerepo=rhel-7-server-optional-beta-rpms install asciidoc **On Funtoo Linux:** To get fuse support and chromaprint (for make check): emerge sys-fs/fuse3 emerge media-libs/chromaprint To get FFmpeg with H264 etc. support, specify some "USE flags" when doing emerge: Create a file /etc/portage/package.use, for example "vi vi /etc/portage/package.use" and add this line: media-video/ffmpeg mp3 x264 opus vorbis vpx This will enable H264, mp3, Opus and WebM support. Next... emerge media-libs/openh264 emerge media-sound/twolame emerge media-video/ffmpeg to build FFmpeg. ### Building FFmpegfs from source code #### Building from tar ball Get the most recent release archive here: https://github.com/nschlia/ffmpegfs/releases Alternatively, utilise these instructions, being sure to download the most recent version: ``` curl -s https://api.github.com/repos/nschlia/ffmpegfs/releases/latest | \ grep "browser_download_url.*gz" | \ cut -d : -f 2,3 | \ tr -d \" | \ wget -i - ``` Unpack the file, and then cd to the source directory. To build and install, run: ./configure make make install Build and execute the test suite by doing: make check This will test audio conversion, tagging and size prediction. #### Building from GIT Clone the most recent version from Github to build from GIT and stay up to date: ``` git clone https://github.com/nschlia/ffmpegfs.git ``` Or from the mirror server: ``` git clone https://salsa.debian.org/nschlia/ffmpegfs.git ``` **If building from git, you'll need these additional prerequisites:** * autoconf * automake * asciidoc (or at least asciidoc-base to save disk space) * w3m * docbook-xml For those who are lazy like me, simply copy and issue this command to get all the prerequisites: apt-get install gcc g++ make pkg-config autoconf automake asciidoc-base docbook-xml xsltproc w3m libchromaprint-dev bc doxygen graphviz FFmpegfs uses the GNU build system, so you'll need to run first: ./autogen.sh If you are downloading a release, this has already been done for you. To build and install, run: ./configure make make install To build and run the test suite, do: make check ### Switching between repository version and source builds It is easy to switch between both worlds. You can do that as many times as you want to, but alas, the cache directory will be cleared every time. But it will be rebuilt in the background, so this will almost go unnoticed. To switch from repository to a source build do ``` apt-get remove ffmpegfs ``` Then follow the steps under "Building FFmpegfs yourself". If you do not remove the repository version, your self-build could inadvertently be up- or downgraded when a new version becomes available from the repository. To switch from a source build to a repository installation, change to the build directory and do ``` make uninstall ``` Then follow the steps under "Installation from repository". ### Building Documentation The help can be created in doc or html format by running make help-pdf make help-html respectively. Building FFmpeg ------------------------------- ### Building FFmpeg with optimisations The precompiled package of FFmpeg available for Debian, Ubuntu, etc. is built with common options so that it can run on many processors. To leverage its full potential, it may be useful to build it with optimisation options for the target CPU. The resulting binaries may not run on other computers. FFmpeg must be built with at least libx264, libfdk_aac, and libmp3lame support. Other libraries, for example, ogg, Windows Media, or FLAC, must be added when these formats should be used as sources. **Attention!** Remember to do "apt remove ffmpeg" before proceeding with the next steps to avoid maleficent blends of custom and official distribution binaries. For a minimum build that contains all the libraries required by FFmpegfs and SSL support for convenience use: configure \ --extra-cflags='-march=native' \ --extra-cflags=-Ofast \ --enable-runtime-cpudetect \ --disable-static \ --enable-gpl \ --enable-shared \ --enable-version3 \ --enable-nonfree \ --enable-pthreads \ --enable-postproc \ --enable-openssl \ --enable-libvpx \ --enable-libvorbis \ --enable-swresample \ --enable-libmp3lame \ --enable-libtheora \ --enable-libxvid \ --enable-libx264 Fix the complaints by configure, i.e., installing the required development packages, then make install This works for me. Decoding runs much faster with these settings. **NOTE:** Depending on the source formats you have, it may be required to add additional libraries. Trouble Shooting ---------------- ### Mounting via /etc/fstab fails An fstab line with fuse.ffmpegfs file system fails with a strange message when attempted to mount with "mount -av". No log entries, no other hints... ``` mount: wrong fs type, bad option, bad superblock on /mnt/sdf1/mp3base1, missing codepage or helper program, or other error ​ In some cases useful info is found in syslog - try ​ dmesg | tail or so. ``` Fuse is missing! Do... apt-get install fuse ### fuse: failed to exec fusermount: No such file or directory Trying to mount as any other than root, the message fuse: failed to exec fusermount: No such file or directory is printed. Fuse is missing! Do... apt-get install fuse ### "ERROR: libmp3lame >= 3.98.3 not found" If you run into this "ERROR: libmp3lame >= 3.98.3 not found" although you have built and installed libmp3lame you may find a solution here: https://stackoverflow.com/questions/35937403/error-libmp3lame-3-98-3-not-found ### autogen.sh displays "possibly undefined macro" Running autoreconf --install configure.ac:46: error: possibly undefined macro: AC_DEFINE If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. autoreconf: /usr/bin/autoconf failed with exit status: 1 You are probably missing out on pkg-config; either it is not installed or not in path. "apt-get install pkg-config" (on Debian or equivalent on other Linux distributions) should help. ### If the videotag.php script does not work under PHP7 The script runs fine under PHP5, but when upgrading to PHP7 (or using PHP7) it suddenly stops showing the list of files. Check the Apache2 error.log, you might see this: "PHP Fatal error: Uncaught Error: Call to undefined function utf8_encode() in index.php" This is because, for some reason, utf8_encode() has been moved to the XML library. Just do (or similar): apt-get install php7.0-xml systemctl restart apache2 And your troubles should be gone. ### "make check": all audio checks fail Log files contain "bc: command not found", so the command line communicator is missing. Fix it by installing (or similar): apt-get install bc ### Make reports "/bin/sh: a2x: command not found" You are missing out on asciidoc. To install it, do (or similar): apt-get install asciidoc-base That should fix it. ### "make help-pdf" reports "non-zero exit status 127" Running "make help-pdf" fails like this: $ make -s help-pdf GEN ffmpegfs.1.pdf a2x: ERROR: "fop" -fo "ffmpegfs.1.fo" -pdf "ffmpegfs.1.pdf" returned non-zero exit status 127 make: *** [Makefile:918: ffmpegfs.1.pdf] Error 1 This happens when "fop" is missing, a command line wrapper for the Java version of fop. apt-get install fop That should do it. ### Make reports xmllint" --nonet --noout --valid "/home/jenkins/dev/ffmpegfs/ffmpegfs.1.xml" returned non-zero exit To find out more, run "make V=1". If you see something like (sic) "validity error : Validation failed: no DTD found !", this means that xmlint cannot access a DTD file because it is run with the --nonet option. This can be solved by apt-get install docbook-xml which will make the required files available offline. ### libbluray fails to load libbluray.jar When you see this message while accessing blurays: bdj.c:340: libbluray-j2se-0.9.3.jar not found. bdj.c:466: BD-J check: Failed to load libbluray.jar To get rid of this message, simply install "libbluray-bdj". This will make it go away. Though not necessary, as to read the Blu-ray tracks, Java support is not required, so this is simply cosmetical.

In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir.

'IN_DIR' 'OUT_DIR' == DESCRIPTION == The ffmpegfs(1) command will mount the directory 'IN_DIR' on 'OUT_DIR'. Thereafter, accessing 'OUT_DIR' will show the contents of 'IN_DIR', with all supported media files transparently renamed and transcoded to one of the supported target formats upon access. Supported output formats: [width="100%"] |=================================================================================== | *Format* | *Description* | *Audio* | *Video* | AIFF | Audio Interchange File Format | | PCM 16 bit BE | ALAC | Apple Lossless Audio Codec | | ALAC | FLAC | Free Lossless Audio | | FLAC | HLS | HTTP Live Streaming | H264 | AAC | MOV | QuickTime File Format | H264 | AAC | MP3 | MPEG-2 Audio Layer III | | MP3 | MP4 | MPEG-4 | H264 | AAC | OGG | | Theora | Vorbis | MKV | Matroska | H264 | AAC | Opus | | Opus | | ProRes | Apple ProRes | ProRes | PCM 16 bit LE | TS | MPEG Transport Stream | H264 | AAC | WAV | Waveform Audio File Format | | PCM 16 bit LE | WebM | | VP9 | Opus | BMP | Video to frameset | | BMP | JPG | Video to frameset | | JPEG | PNG | Video to frameset | | PNG |=================================================================================== == OPTIONS == Usage: ffmpegfs [OPTION]... IN_DIR OUT_DIR Mount IN_DIR on OUT_DIR, converting audio and video files upon access. === Encoding options === *--desttype*=TYPE, *-odesttype*=TYPE:: Select the destination format. 'TYPE' can currently be: + *AIFF*, *ALAC*, *BMP*, *FLAC*, *HLS*, *JPG*, *MOV*, *MP3*, *MP4*, *MKV*, *OGG*, *Opus*, *PNG*, *ProRes*, *TS*, *WAV*, *WebM*. + To stream videos, *MP4*, *TS*, *HLS*, *OGG*, *WEBM*, *MKV*, or *MOV*/*PRORES* must be selected. + To use HTTP Live Streaming, set *HLS*. + When a destination *JPG*, *PNG*, or *BMP* is chosen, all frames of a video source file will be presented in a virtual directory named after the source file. Audio will not be available. + To use the smart transcoding feature, specify a video and audio file type, separated by a "+" sign. For example, --desttype=mov+aiff will convert video files to Apple Quicktime MOV and audio-only files to AIFF. + Defaults to: *mp4* *--audiocodec*=TYPE, *-oaudiocodec*=TYPE:: Select an audio codec. 'TYPE' depends on the destination format and can currently be: + [width="100%"] |=================================================================================== | *Formats* | *Audio Codecs* | MP4 | **AAC**, MP3 | WebM | **OPUS**, VORBIS | MOV | **AAC**, AC3, MP3 | MKV | **AAC**, AC3, MP3 | TS, HLS | **AAC**, AC3, MP3 |=================================================================================== + Other destination formats do not support other codecs than the default. + Defaults to: The destination format's default setting, as indicated by the first codec name in the list. *--videocodec*=TYPE, *-ovideocodec*=TYPE:: Select a video codec. 'TYPE' depends on the destination format and can currently be: + [width="100%"] |=================================================================================== | *Formats* | *Video Codecs* | MP4 | **H264**, H265, MPEG1, MPEG2 | WebM | **VP9**, VP8, AV1 | MOV | **H264**, H265, MPEG1, MPEG2 | MKV | **H264**, H265, MPEG1, MPEG2 | TS, HLS | **H264**, H265, MPEG1, MPEG2 |=================================================================================== + Other destination formats do not support other codecs than the default. + Defaults to: The destination format's default setting, as indicated by the first codec name in the list. *--autocopy*=OPTION, *-oautocopy*=OPTION:: Select the auto copy option. 'OPTION' can be: + [width="100%"] |=================================================================================== |*OFF* |Never copy streams, transcode always. |*MATCH* |Copy stream if target supports codec. |*MATCHLIMIT* |Same as MATCH, only copy if target not larger, transcode otherwise. |*STRICT* |Copy stream if codec matches desired target, transcode otherwise. |*STRICTLIMIT* |Same as STRICT, only copy if target not larger, transcode otherwise. |=================================================================================== + This can speed up transcoding significantly as copying streams uses much less computing power as compared to transcoding. + *MATCH* copies a stream if the target supports it, e.g., an AAC audio stream will be copied to MPEG, although FFmpeg's target format is MP3 for this container. H264 would be copied to ProRes, although the result would be a regular MOV or MP4, not a ProRes file. + *STRICT* would convert AAC to MP3 for MPEG or H264 to ProRes for Prores files to strictly adhere to the output format setting. This will create homogenous results which might prevent problems with picky playback software. + Note: When the *--audiocodec* or *--videocodec* option is specified, the STRICT option should be used to ensure that the chosen output codec is used in any scenario. MATCH would enable copy if the output format supports the input codec. Defaults to: *OFF* *--recodesame*=OPTION, *-orecodesame*=OPTION:: Select recode to the same format option, 'OPTION' can be: + [width="100%"] |=================================================================================== |*NO* |Never recode to the same format. |*YES* |Always recode to the same format. |=================================================================================== + Defaults to: *NO* *--profile*=NAME, *-oprofile*=NAME:: Set profile for target audience, 'NAME' can be: + [width="100%"] |======================================================= |*NONE* |no profile |*FF* |optimise for Firefox |*EDGE* |optimise for MS Edge and Internet Explorer > 11 |*IE* |optimise for MS Edge and Internet Explorer <= 11 |*CHROME* |Google Chrome |*SAFARI* |Apple Safari |*OPERA* |Opera |*MAXTHON* |Maxthon |======================================================= + *Note:* applies to the MP4 output format only, and is ignored for all other formats. + Defaults to: *NONE* --*level*=NAME, -o *level*=NAME:: Set level for output if available.

'LIST' can have one or more entries that are separated by commas. These are the only file extensions that will be transcoded. Can be specified numerous times and will be merged, which is required when specifying them in the fstab because commas cannot be used to separate the extensions. The entries support shell wildcard patterns. + Example: --include_extensions=mp4,wmv to encode MPEG-4 and Windows Media files only. + Defaults to: Encode all supported files. *--hide_extensions*=LIST, *-ohide_extensions*=LIST:: Set a list of file extensions to exclude from the output. 'LIST' can have one or more entries that are separated by commas. Can be specified numerous times and will be merged, which is required when specifying them in the fstab because commas cannot be used to separate the extensions. The entries support shell wildcard patterns. + Example: --hide_extensions=jpg,png,cue to stop covers and cue sheets from showing up. + Defaults to: Show all files. === Audio Options === *--audiobitrate*=BITRATE, *-o audiobitrate*=BITRATE:: Select the audio encoding bitrate. + Defaults to: *128 kbit* + *Acceptable values for 'BITRATE':* + *mp4:* 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144, 160, 176, 192, 224, 256, 288, 320, 352, 384, 416, and 448 kbps. + *mp3:* For sampling frequencies of 32, 44.1, and 48 kHz, 'BITRATE' can be among 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, and 320 kbps. + For sampling frequencies of 16, 22.05, and 24 kHz, 'BITRATE' can be among 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144, and 160 kbps. + When in doubt, it is recommended to choose a bitrate among 96, 112, 128, 160, 192, 224, 256, and 320 kbps. + -- *BITRATE*:: can be defined as... * n bit/s: # or #bps * n kbit/s: #K or #Kbps * n Mbit/s: #M or #Mbps -- *--audiosamplerate*=SAMPLERATE, *-o audiosamplerate*=SAMPLERATE:: This limits the output sample rate to 'SAMPLERATE'. If the source file sample rate is higher, it will be downsampled automatically. + Typical values are 8000, 11025, 22050, 44100, 48000, 96000, and 192000. + If the target codec does not support the selected sample rate, the next matching rate will be chosen (e.g. if 24K is selected but only 22.05 or 44.1 KHz is supported, 22.05 KHz will be set). + Set to 0 to keep the source rate. + Defaults to: *44.1 kHz* + -- *SAMPLERATE*:: can be defined as... * In Hz: # or #Hz * In kHz: #K or #KHz -- *--audiochannels*=CHANNELS, *-o audiochannels*=CHANNELS:: This limits the number of output channels to 'CHANNELS'. If the source has more channels, the number will be reduced to this limit. + Typical values are 1, 2 or 6 (e.g., 5.1) channels. + If the target codec does not support the selected number of channels, transcoding may fail. + Set to 0 to keep the number of channels. + Defaults to: *2 channels (stereo)* *--audiosamplefmt*=SAMPLEFMT, *-o audiosamplefmt*=SAMPLEFMT:: This sets a sample format. 'SAMPLEFMT' can be: + 0 to use the predefined setting; 8, 16, 32, 64 for integer format, F16, F32, F64 for floating point. + Not all formats are supported by all destination types. Selecting an invalid format will be reported as a command line error and a list of values printed. + [width="100%"] |=========================== |*Container Format* | *Sample Format* |*AIFF* |0, 16, 32 |*ALAC* |0, 16, 24 |*WAV* |0, 8, 16, 32, 64, F16, F32, F64 |*FLAC* |0, 16, 24 |=========================== + Defaults to: 0 (Use the same as the source or the predefined format of the destination if the source format is not possible.) === Video Options === *--videobitrate*=BITRATE, *-o videobitrate*=BITRATE:: This sets the video encoding bit rate. Setting this too high or too low may cause transcoding to fail. + Defaults to: *2 Mbit* + *mp4:* May be specified as 500 to 25,000 kbps. + -- *BITRATE*:: can be defined as... * n bit/s: # or #bps * n kbit/s: #K or #Kbps * n Mbit/s: #M or #Mbps -- *--videoheight*=HEIGHT, -o *videoheight*=HEIGHT:: This sets the height of the transcoded video. + When the video is rescaled, the aspect ratio is preserved if --width is not set at the same time. + Defaults to: *keep source video height* *--videowidth*=WIDTH, -o *videowidth*=WIDTH:: This sets the width of the transcoded video. + When the video is rescaled, the aspect ratio is preserved if --height is not set at the same time. + Defaults to: *keep source video width* *--deinterlace*, -o *deinterlace*:: Deinterlace video if necessary while transcoding. + This may need a higher bit rate, but this will increase picture quality when streaming via HTML5. + Defaults to: "no deinterlace" === HLS Options === *--segment_duration*, -o *segment_duration*:: Set the duration of one video segment of the HLS stream.

Audio bitrates will be reduced to 256 KBit, video to 1.5 MBit. The source bitrate will not be scaled up if it is lower; it will remain at the lower value. Keep in mind that only root can, by default, utilise the "allow other" option. Either use the "user allow other" key in /etc/fuse.conf or run FFmpegfs as root. Any user must have "allow other" enabled in order to access the mount. By default, only the user who initiated FFmpegfs has access to this. Examples: ffmpegfs -f $HOME/test/in $HOME/test/out --log_stderr --log_maxlevel=DEBUG -o allow_other,ro,desttype=mp4,cachepath=$HOME/test/cache Transcode files using FFmpegfs from test/in to test/out while logging to stderr at a noisy TRACE level. The cache resides in test/cache. All directories are under the current user's home directory. ffmpegfs -f $HOME/test/in $HOME/test/out --log_stderr --log_maxlevel=DEBUG -o allow_other,ro,desttype=mp4,cachepath=$HOME/test/cache,videowidth=640 Similar to the previous, but with a 640-pixel maximum video width. The aspect ratio will be maintained when scaling down larger videos. Videos that are smaller won't be scaled up. ffmpegfs -f $HOME/test/in $HOME/test/out --log_stderr --log_maxlevel=DEBUG -o allow_other,ro,desttype=mp4,cachepath=$HOME/test/cache,deinterlace Deinterlacing can be enabled for better image quality. == HOW IT WORKS == The decoder and encoder are initialised when a file is opened, and the file's metadata is also read. At this point, a rough estimate of the total file size can be made. Because the actual size greatly depends on the material encoded, this technique works fair-to-good for MP4 or WebM output files but works well for MP3, AIFF, or WAV output files. The file is transcoded as it is being read and stored in a private per-file buffer. This buffer keeps expanding as the file is read until the entire file has been transcoded. After being decoded, the file is stored in a disc buffer and is readily accessible. Other processes will share the same transcoded data if they access the same file because transcoding is done in a single additional thread, which saves CPU time. Transcoding will continue for a while if all processes close the file before it is finished. Transcoding will resume if the file is viewed once more before the timer expires. If not, it will halt and delete the current chunk to free up storage space. A file will be transcoded up to the seek point when you seek within it (if not already done). Since the majority of programmes will read a file from beginning to end, this is typically not a problem. Future upgrades might offer actual random seeking (but if this is feasible, it is not yet clear due to restrictions to positioning inside compressed streams). When HLS streaming is chosen, this already functions. The requested segment is immediately skipped to by FFmpegfs. *MP3:* The source file's comments are used to generate ID3 version 2.4 and 1.1 tags. They are correspondingly at the beginning and the end of the file. *MP4:* The same is true for meta atoms contained in MP4 containers. *WAV*: The estimated size of the WAV file will be included in a pro forma WAV header. When the file is complete, this header will be changed. Though most current gamers apparently disregard this information and continue to play the file, it does not seem required. Only for MP3 targets: A particular optimization has been done so that programmes that look for id3v1 tags don't have to wait for the entire file to be transcoded before reading the tag. This accelerates these apps *dramatically*. == ABOUT OUTPUT FORMATS == A few remarks regarding the output formats that are supported: Since these are plain vanilla constant bitrate (CBR) MP3 files, there isn't much to say about the MP3 output. Any modern player should be able to play them well. However, MP4 files are unique because standard MP4s aren't really ideal for live broadcasting. The start block of an MP4 has a field with the size of the compressed data section, which is the cause. It suffices to say that until the size is known, compression must be finished, a file seek must be performed to the beginning, and the size atom updated. That size is unknown for a live stream that is ongoing. To obtain that value for our transcoded files, one would need to wait for the entire file to be recoded. As if that weren't enough, the file's final section contains some crucial details, such as meta tags for the artist, album, etc. Additionally, the fact that there is just one enormous data block makes it difficult to do random searches among the contents without access to the entire data section. Many programmes will then read the crucial information from the end of an MP4 before returning to the file's head and beginning playback. This will destroy FFmpegfs' entire transcode-on-demand concept. Several extensions have been created to work around the restriction, including "faststart," which moves the aforementioned meta data from the end to the beginning of the MP4 file. Additionally, it is possible to omit the size field (0). An further plugin is isml (smooth live streaming). Older versions of FFmpeg do not support several new MP4 features that are required for direct-to-stream transcoding, like ISMV, faststart, separate moof/empty moov, to mention a few (or if available, not working properly). Faststart files are produced by default with an empty size field so that the file can be started to be written out at once rather than having to be encoded as a complete first. It would take some time before playback could begin if it were fully encoded. The data part is divided into chunks of about 1 second each, all with their own header, so it is possible to fill in the size fields early enough. One disadvantage is that not all players agree with the format, or they play it with odd side effects. VLC only refreshes the time display every several seconds while playing the file. There may not always be a complete duration displayed while streaming using HTML5 video tags, but that is fine as long as the content plays. Playback can only move backwards from the current playback position. However, that is the cost of commencing playback quickly. == DEVELOPMENT == Git is the revision control system used by FFmpegfs.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. 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 them 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 prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. 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. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey 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; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If 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 convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU 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 that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. 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. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 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. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. 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 state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 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 3 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, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program 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, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU 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 Lesser General Public License instead of this License.

At this point, a rough estimate of the total file size can be made\&. Because the actual size greatly depends on the material encoded, this technique works fair\-to\-good for MP4 or WebM output files but works well for MP3, AIFF, or WAV output files\&. .sp The file is transcoded as it is being read and stored in a private per\-file buffer\&. This buffer keeps expanding as the file is read until the entire file has been transcoded\&. After being decoded, the file is stored in a disc buffer and is readily accessible\&. .sp Other processes will share the same transcoded data if they access the same file because transcoding is done in a single additional thread, which saves CPU time\&. Transcoding will continue for a while if all processes close the file before it is finished\&. Transcoding will resume if the file is viewed once more before the timer expires\&. If not, it will halt and delete the current chunk to free up storage space\&. .sp A file will be transcoded up to the seek point when you seek within it (if not already done)\&. Since the majority of programmes will read a file from beginning to end, this is typically not a problem\&. Future upgrades might offer actual random seeking (but if this is feasible, it is not yet clear due to restrictions to positioning inside compressed streams)\&. When HLS streaming is chosen, this already functions\&. The requested segment is immediately skipped to by FFmpegfs\&. .sp \fBMP3:\fR The source file\(cqs comments are used to generate ID3 version 2\&.4 and 1\&.1 tags\&. They are correspondingly at the beginning and the end of the file\&. .sp \fBMP4:\fR The same is true for meta atoms contained in MP4 containers\&. .sp \fBWAV\fR: The estimated size of the WAV file will be included in a pro forma WAV header\&. When the file is complete, this header will be changed\&. Though most current gamers apparently disregard this information and continue to play the file, it does not seem required\&. .sp Only for MP3 targets: A particular optimization has been done so that programmes that look for id3v1 tags don\(cqt have to wait for the entire file to be transcoded before reading the tag\&. This accelerates these apps \fBdramatically\fR\&. .SH "ABOUT OUTPUT FORMATS" .sp A few remarks regarding the output formats that are supported: .sp Since these are plain vanilla constant bitrate (CBR) MP3 files, there isn\(cqt much to say about the MP3 output\&. Any modern player should be able to play them well\&. .sp However, MP4 files are unique because standard MP4s aren\(cqt really ideal for live broadcasting\&. The start block of an MP4 has a field with the size of the compressed data section, which is the cause\&. It suffices to say that until the size is known, compression must be finished, a file seek must be performed to the beginning, and the size atom updated\&. .sp That size is unknown for a live stream that is ongoing\&. To obtain that value for our transcoded files, one would need to wait for the entire file to be recoded\&. As if that weren\(cqt enough, the file\(cqs final section contains some crucial details, such as meta tags for the artist, album, etc\&. Additionally, the fact that there is just one enormous data block makes it difficult to do random searches among the contents without access to the entire data section\&. .sp Many programmes will then read the crucial information from the end of an MP4 before returning to the file\(cqs head and beginning playback\&. This will destroy FFmpegfs\*(Aq entire transcode\-on\-demand concept\&. .sp Several extensions have been created to work around the restriction, including "faststart," which moves the aforementioned meta data from the end to the beginning of the MP4 file\&. Additionally, it is possible to omit the size field (0)\&. An further plugin is isml (smooth live streaming)\&. .sp Older versions of FFmpeg do not support several new MP4 features that are required for direct\-to\-stream transcoding, like ISMV, faststart, separate moof/empty moov, to mention a few (or if available, not working properly)\&. .sp Faststart files are produced by default with an empty size field so that the file can be started to be written out at once rather than having to be encoded as a complete first\&. It would take some time before playback could begin if it were fully encoded\&. The data part is divided into chunks of about 1 second each, all with their own header, so it is possible to fill in the size fields early enough\&. .sp One disadvantage is that not all players agree with the format, or they play it with odd side effects\&. VLC only refreshes the time display every several seconds while playing the file\&. There may not always be a complete duration displayed while streaming using HTML5 video tags, but that is fine as long as the content plays\&. Playback can only move backwards from the current playback position\&. .sp However, that is the cost of commencing playback quickly\&. .SH "DEVELOPMENT" .sp Git is the revision control system used by FFmpegfs\&.
