* lavc/golomb: unmerge the cached bitstream reader codebitstream_unmergeAlexandra Hájková2022-01-25
| | | | | | | | | | Move the cached bitstream reader code to a new header, which can either be used on its own with the cached bitstream reader, or from get_bits code by #defining CACHED_BITSTREAM_READER. Restore proper attribution for this code. Integration by Anton Khirnov <anton@khirnov.net>
* lavc/get_bits: add a compat wrapper for the cached bitstream readerAnton Khirnov2022-01-25
| | | | Use that instead of the merged version.
* lavc/bitstream: make skip_remaining() publicAnton Khirnov2022-01-25
| | | | | Also rename it to bitstream_skip_cache(), which is more descriptive and follows the naming conventions of tis API.
* lavc/bitstream: templatize for BE/LEAnton Khirnov2022-01-25
| | | | Allows using both BE and LE bitstream readers in the same file.
* lavc: add standalone cached bitstream readerAlexandra Hájková2022-01-25
| | | | | | | | | | | | | | | | | | | | The cached bitstream reader was originally written by Alexandra Hájková for Libav, with significant input from Kostya Shishkov and Luca Barbato. It was then committed to FFmpeg in ca079b09549, by merging it with the implementation of the current bitstream reader. This merge makes the code of get_bits.h significantly harder to read, since it now contains two different bitstream readers interleaved with #ifdefs. Additionally, the code was committed without proper authorship attribution. This commit re-adds the cached bitstream reader as a standalone header, as it was originally developed. It will be made useful in following commits. Integration by Anton Khirnov. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* lavc/svq3: stop including h264dec.hAnton Khirnov2022-01-24
| | | | | | | | The only thing that is actually used directly from there is the PART_NOT_AVAILABLE constant, which can be trivially copied to svq3 decoder itself. Otherwise it only depends on other indirectly included headers.

* lavc/h264_parse: stop including h264dec.hAnton Khirnov2022-01-24
| | | | | | It is unnecessary and only files that are parts of the decoder (as opposed to standalone code called by the decoder) are allowed to include h264dec.h

* lavc/h264: replace MAX_MMCO_COUNT with H264_MAX_MMCO_COUNTAnton Khirnov2022-01-24
| | | | | | They apparently serve the same purpose; the latter is one larger and has a comment explaining how the value is derived, so seems more trustworthy.

* avformat/mux: Peek into the muxing queue for avoid_negative_tsAndreas Rheinhardt2022-01-21
| | | | | | | | | | | Peeking into the muxing queue can improve the estimate of the lowest timestamp needed for avoid_negative_ts in case the lowest timestamp is in a packet other than the first packet to be muxed. This fixes tickets #4536 and #5784 as well as the output from the matroska-avoid-negative-ts FATE-test. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/mux: Preserve sync even if later packet has negative tsAndreas Rheinhardt2022-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | write_packet() has code to shift the packets timestamps to make them nonnegative or even make them start at ts zero; this code inspects every packet that is written and if a packet with negative timestamp (whether this is dts or pts depends upon another flag; basically: Matroska uses pts, everyone else dts) is encountered, this is offset to make the timestamp zero. All further packets will be offset accordingly (with the offset converted according to the streams' timebases). This is based around an assumption, namely that the timestamps are indeed non-decreasing, so that the first packet with negative timestamps is the first packet with timestamps. This assumption is often fulfilled given that the default interleavement function by default interleaves per dts; yet there are scenarios in which it may not be fulfilled: a) av_write_frame() instead of av_interleaved_write_frame() is used. b) The audio_preload option is used. c) When the timestamps that are made nonnegative/zero are pts (i.e. with Matroska), because the packet with the smallest dts is not necessarily the packet with the smallest pts. d) Possibly with custom interleavement functions. In these cases the relative sync of the first few packet(s) is offset relative to the later packets. This contradicts the documentation ("When shifting is enabled, all output timestamps are shifted by the same amount"). Therefore this commit changes this: As soon as the first packet with valid timestamps is output, it is checked and recorded whether the timestamps need to be shifted. Further packets are no longer checked for needing to be offset; instead they are simply offset. In the cases above this leads to packets with negative timestamps (and the appropriate warnings) instead of desync. This will mostly be fixed in the next commit. This commit also factors handling the avoid_negative_ts stuff out of write_packet() in order to be able to return immediately. Tickets #4536 and #5784 as well as the matroska-avoid-negative-ts-test are examples of c); as has been said, some timestamps are now negative, yet the ref file update does not show it because ffmpeg.c sanitizes the timestamps (-copyts disables it; ffprobe and mkvinfo also show the original timestamps).

* avformat/mux: Remove assert based on faulty assumptionsAndreas Rheinhardt2022-01-21
| | | | | | | | | This assert is based upon the wrong assumption that the noninterleaved codepath is never used; if it is used, max_interleave_delta is irrelevant. It furthermore ignores audio_preload. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
