As a result, the MOV muxer, which uses AVStream::avg_frame_rate to determine the timecode frame rate, will fail when copying a track: {{{ffmpeg -f imf -i countdown-small/CPL_bb2ce11c- 1bb6-4781-8e69-967183d02b9b.xml -map 0 -c copy -t 5 -shortest build/out.mov}}} Suggest setting the avg_frame_rate and r_frame_rate of the video stream to the edit_rate of the MXF track. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9856> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#8929: ffmpeg can encode rgb av1 webm files but not decode them -------------------------------------+------------------------------------- Reporter: | Type: defect av1masterrace | Status: new | Priority: important Component: ffmpeg | Version: | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: If I use the newest version to encode a gif to an av1 webm it will choose gbrp which is great because it keeps the colours the same. It also decodes fine in Chromium and mpv. However in VLC and ffplay white becomes pink and it all looks horrible. Same when decoding into another format with ffmpeg. I don't know whether this also affects rgb av1 in other containers like mkv or mp4.
