Tests mostly work for me. There are a few images (that I reported earlier) that give: Canvas change detected. The output will be damaged. Use -threads 1 to try decoding with best effort. They don't animate without that option and with it render incorrectly. A few other notes: - should ffprobe report anything with files containing xmp? - 0 duration behaves differently than web browsers, which use the gif behavior and set it to 10; as long as it's consistent in ffmpeg between the two either is fine to me. - The files in https://crbug.com/690848 don't exit cleanly from ffplay, other corrupt files do; ffmpeg exits, so maybe it's a non-issue. > > Patch 5/8 is still there for making changes in lavc/webp reviewable but shall > be stashed when pushing. > > -Thilo > > Josef Zlomek (2): > libavcodec/webp: add support for animated WebP > libavformat/webp: add WebP demuxer > > Thilo Borgmann via ffmpeg-devel (6): > avcodec/webp: remove unused definitions > avcodec/webp: separate VP8 decoding > avcodec/bsf: Add awebp2webp bitstream filter > avcodec/webp: make init_canvas_frame static > fate: add test for animated WebP > avcodec/webp: export XMP metadata > > Changelog | 2 + > configure | 1 + > doc/demuxers.texi | 28 + > libavcodec/bitstream_filters.c | 1 + > libavcodec/bsf/Makefile | 1 + > libavcodec/bsf/awebp2webp.c | 350 ++++++++ > libavcodec/codec_desc.c | 3 +- > libavcodec/version.h | 2 +- > libavcodec/webp.c | 796 ++++++++++++++++-- > libavformat/Makefile | 1 + > libavformat/allformats.c | 1 + > libavformat/version.h | 2 +- > libavformat/webpdec.c | 383 +++++++++ > tests/fate/image.mak | 3 + > tests/ref/fate/exif-image-webp | 4 +- > tests/ref/fate/webp-anim | 22 + > tests/ref/fate/webp-rgb-lena-lossless | 2 +- > tests/ref/fate/webp-rgb-lena-lossless-rgb24 | 2 +- > tests/ref/fate/webp-rgb-lossless | 2 +- > .../fate/webp-rgb-lossless-palette-predictor | 2 +- > tests/ref/fate/webp-rgb-lossy-q80 | 2 +- > tests/ref/fate/webp-rgba-lossless | 2 +- > tests/ref/fate/webp-rgba-lossy-q80 | 2 +- > 23 files changed, 1530 insertions(+), 84 deletions(-) > create mode 100644 libavcodec/bsf/awebp2webp.c > create mode 100644 libavformat/webpdec.c > create mode 100644 tests/ref/fate/webp-anim > > -- > 2.43.0 > > _______________________________________________ > 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". _______________________________________________ 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".
