Hello, this patchset is about the Matroska muxer. It consists partially of patches from my earlier patchset [1] that is currently blocked by the webm_chunk muxer [2].
One focus of this patchset is about improving writing Cues; in particular, an assert that is triggered if the reserved space for writing Cues in front exceeds the needed space by one byte is fixed. Furthermore, the checks involved in writing SeekHeads were fixed. This goes beyond what was done in the earlier patchset. - Andreas [1]: https://ffmpeg.org/pipermail/ffmpeg-devel/2019-November/252578.html [2]: https://ffmpeg.org/pipermail/ffmpeg-devel/2019-December/254783.html Andreas Rheinhardt (20): avformat/matroskaenc: Fix ReferenceBlock timestamp avformat/matroskaenc: Improve writing Projection avformat/matroskaenc: Remove useless AVIOContext avformat/matroskaenc: Adapt documentation of put_ebml_num avformat/matroskaenc: Check return value of ff_isom_write_hvcc() avformat/matroskaenc: Check functions that can fail avformat/matroskaenc: Avoid allocations for SeekHead avformat/matroskaenc: Improve calculating EBML ID size avformat/matroskaenc: Check for failure when writing SeekHead avformat/matroskaenc: Avoid unnecessary seek avformat/matroskaenc: Cosmetics avformat/matroskaenc: Avoid allocation for Cues avformat/aviobuf: Add function to reset dynamic buffer avformat/matroskadec: Simplify writing Cues avformat/matroskaenc: Write level 1 elements in one go avformat/matroskaenc: Remove unused function parameter avformat/matroskaenc: Check that Cluster has been opened avformat/matroskaenc: Don't fail if reserved Cues space doesn't suffice avformat/matroskaenc: Fix edge case of writing Cues at the beginning avformat/matroskaenc: Avoid seek when writing Cues at the front doc/muxers.texi | 4 +- libavformat/avio_internal.h | 7 + libavformat/aviobuf.c | 11 + libavformat/matroskaenc.c | 516 ++++++++++++--------------- tests/fate/matroska.mak | 2 +- tests/fate/wavpack.mak | 4 +- tests/ref/fate/aac-autobsf-adtstoasc | 4 +- tests/ref/fate/binsub-mksenc | 2 +- tests/ref/fate/rgb24-mkv | 4 +- tests/ref/lavf/mka | 4 +- tests/ref/lavf/mkv | 4 +- tests/ref/lavf/mkv_attachment | 4 +- tests/ref/seek/lavf-mkv | 44 +-- 13 files changed, 286 insertions(+), 324 deletions(-) -- 2.20.1 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
