* fftools/ffmpeg_filter: implement filtergraph chainingAnton Khirnov2024-04-09
| | | | | | | | | | This allows one complex filtergraph's output to be sent as input to another one, which is useful in certain situations (one is described in the docs). Chaining filtergraphs was already effectively possible by using a wrapped_avframe encoder connected to a loopback decoder, but it is ugly, non-obvious and inefficient.
* avcodec/liblc3: add encoding/decoding support of LC3 audio codecAntoine Soulier via ffmpeg-devel2024-04-04
| | | | | | | The LC3 audio codec is the default codec of Bluetooth LE audio. This is a wrapper over the liblc3 library (https://github.com/google/liblc3). Signed-off-by: Antoine Soulier <asoulier@google.com>

* avformat/rcwtdec: add RCWT Closed Captions demuxerMarth642024-04-02
| | | | | | | | | | | | | | | RCWT (Raw Captions With Time) is a format native to ccextractor, a commonly used OSS tool for processing 608/708 Closed Captions (CC). RCWT can be used to archive the original extracted CC bitstream. The muxer was added in January 2024. In this commit, add the demuxer. One can now demux RCWT files for rendering in ccaption_dec or interop with ccextractor (which produces RCWT). Using the muxer/demuxer combo, the CC bits can be kept for processing or rendering with either tool. This can be an effective way to backup an original CC stream, including format extensions like EIA-708 and overall original presentation. Signed-off-by: Marth64 <marth64@proxyid.net>

| | | | | | | | | It should be available in all relevant modern compilers and will allow us to use features like anonymous unions. Note that stdatomic.h is still emulated on MSVC, as current versions require the /experimental:c11atomics, and do not support ATOMIC_VAR_INIT() anyway.

* libavformat: add RCWT closed caption muxexMarth642024-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Signed-off-by: Marth64 <marth64@proxyid.net> Raw Captions With Time (RCWT) is a format native to ccextractor, a commonly used open source tool for processing 608/708 closed caption (CC) sources. It can be used to archive the original, raw CC bitstream and to produce a source file file for later CC processing or conversion. As a result, it also allows for interopability with ccextractor for processing CC data extracted via ffmpeg. The format is simple to parse and can be used to retain all lines and variants of CC. A free specification of RCWT can be found here: https://github.com/CCExtractor/ccextractor/blob/master/docs/BINARY_FILE_FORMAT.TXT This muxer implements the specification as of 01/05/2024, which has been stable and unchanged for 10 years as of this writing. This muxer will have some nuances from the way that ccextractor muxes RCWT. No compatibility issues when processing the output with ccextractor have been observed as a result of this so far, but mileage may vary and outputs will not be a bit-exact match. Specifically, the differences are: (1) This muxer will identify as "FF" as the writing program identifier, so as to be honest about the output's origin. (2) ffmpeg's MPEG-1/2, H264, HEVC, etc. decoders extract closed captioning data differently than ccextractor from embedded SEI/user data. For example, DVD captioning bytes will be translated to ATSC A53 format. This allows ffmpeg to handle 608/708 in a consistant way downstream. This is a lossless conversion and the meaningful data is retained. (3) This muxer will not alter the extracted data except to remove invalid packets in between valid CC blocks. On the other hand, ccextractor will by default remove mid-stream padding, and add padding at the end of the stream (in order to convey the end time of the source video).

* fftools/ffmpeg: convert to a threaded architectureAnton Khirnov2023-12-12
| | | | | | | | | | Change the main loop and every component (demuxers, decoders, filters, encoders, muxers) to use the previously added transcode scheduler. Every instance of every such component was already running in a separate thread, but now they can actually run in parallel. Changes the results of ffmpeg-fix_sub_duration_heartbeat - tested by JEEB to be more correct and deterministic.

* ffprobe: fix XML rendering, review XML layoutStefano Sabatini2023-10-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix rendering of int values within a side data element, which was broken since commit d2d3a83ad93, where the side data element was correctly marked as a variable fields element. Logic to render a string variable was implemented already, but it was not implemented for the int fields path, which was enabled by that commit. Also, code and schema is changed in order to account for multiple variable-fields elements - such as side data, contained within the same parent. Previously it was assumed that a single variable-fields element was contained within the parent, which was the case for tags, but is not the case for side-data. Previously data was rendered as: <side_data_list> <side_data side_data_type="CPB properties" max_bitrate="0" min_bitrate="0" avg_bitrate="0" buffer_size="327680" vbv_delay="-1"/> </side_data_list> Now as: <side_data_list> <side_data type="CPB properties"> <side_datum key="side_data_type" value="CPB properties"/> <side_datum key="max_bitrate" value="0"/> <side_datum key="min_bitrate" value="0"/> <side_datum key="avg_bitrate" value="0"/> <side_datum key="buffer_size" value="49152"/> <side_datum key="vbv_delay" value="-1"/> </side_data> </side_data_list> Variable-fields elements are rendered as a containing element wrapping generic key/values elements, enabling use of strict XML schema.
