For a long time, MKVToolNix de-facto set the standards for how to mux certain codecs into Matroska and other tools (like FFmpeg) simply followed its lead. This was never how it was supposed to happen, but it was necessary to get things done. But times have changed and today a codec mapping is a prerequisite for adding support for a codec. - Andreas _______________________________________________ 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".
