This is a series of patches to allow proper decoding of ogg metadata in chained `ogg/vorbis, `ogg/flac` and `ogg/opus` streams.
## Changes since last version: * Metadata update is now using a factored out function from the vorbis decoder which includes update the underlying AVStream metadata and setting AVSTREAM_EVENT_FLAG_METADATA_UPDATED on it. * New vorbis comment metadata erase existing ones instead of appending * Test utility is updated to include the stream's metadata * A test for chained ogg/vorbis metadata is added. Last version and discussion: https://ffmpeg.org/pipermail/ffmpeg-devel/2025-February/339887.html Romain Beauxis (9): libavcodec/decode.c: intercept `AV_PKT_DATA_METADATA_UPDATE` packet extra data, attach them to the next decoded frame. tests: Add stream dump test API util. libavformat/oggparsevorbis.c: Don't append new metadata. tests: Add chained ogg/vorbis stream dump test. libavformat/oggdec.h, libavformat/oggparsevorbis.c: Factor out vorbis metadata update mechanism. libavformat/oggparseflac.c: Parse ogg/flac comments in new ogg packets, add them to ogg stream new_metadata. tests: Add chained ogg/flac stream dump test. libavformat/oggparseopus.c: Parse comments from secondary chained streams header packet. tests: Add chained ogg/opus stream dump test. libavcodec/decode.c | 20 +++ libavformat/oggdec.h | 14 +++ libavformat/oggparseflac.c | 21 ++++ libavformat/oggparseopus.c | 13 +- libavformat/oggparsevorbis.c | 29 +++-- tests/Makefile | 4 + tests/api/Makefile | 2 +- tests/api/api-dump-stream-meta-test.c | 175 ++++++++++++++++++++++++++ tests/fate/ogg-flac.mak | 11 ++ tests/fate/ogg-opus.mak | 11 ++ tests/fate/ogg-vorbis.mak | 11 ++ 11 files changed, 298 insertions(+), 13 deletions(-) create mode 100644 tests/api/api-dump-stream-meta-test.c create mode 100644 tests/fate/ogg-flac.mak create mode 100644 tests/fate/ogg-opus.mak create mode 100644 tests/fate/ogg-vorbis.mak -- 2.39.5 (Apple Git-154) _______________________________________________ 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".
