#3256: FFMPEG SVQ3 Matroska remux produces unplayable output (FFPlay don't want to play SVQ3 MKV output) -------------------------------------+------------------------------------- Reporter: Vika | Owner: Apelsinova | Status: open Type: defect | Component: avformat Priority: important | Resolution: Version: git-master | Blocked By: Keywords: mkv svq3 | Reproduced by developer: 1 regression | Blocking: | Analyzed by developer: 1 | -------------------------------------+------------------------------------- Comment (by Vika Apelsinova): The bug was fixed in MKVToolNix by https://github.com/mbunkus/mkvtoolnix/commit/6fbbd882d2b0819b2e3a4d4fc2880f9..., but FFPlay and VLC still don't want to play output. [[BR]]
Not really, the output file was invalid (and can not be decoded with vlc).

Just do a recursive grep for A_QUICKTIME on VLC's sources and you'll see for yourself. As for the CodecID. mkvmerge has used A_QUICKTIME since 2009. Before it used A_QUICKTIME/QDMx. Back then there was a decision that appending the codec type to the A_QUICKTIME string was superfluous as the FourCC is contained in CodecPrivate for both A_QUICKTIME and A_QUICKTIME/QDMx. This is very similar to how V_QUICKTIME works. The CodecPrivate contains the content of the STSD atom. Unfortunately we totally forgot to update the specs page, which is why it doesn't list A_QUICKTIME. I will update the specs page tonight. So if you want to fix ffmpeg you should do the following: 1. In the demuxing part: treat A_QUICKTIME and A_QUICKTIME/wxyz identically. Get the FourCC from CodecPrivate (should be bytes 4 - 7 starting at 0). 2. In the muxing part: simply don't write A_QUICKTIME/wxyz but just A_QUICKTIME. }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/3256#comment:6> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

ffplay can now play the video from output-mkvtoolnix-6.6.0.mkv
Why only video? Ok, everything is clear with FFPlay (decoding). What with encoding? The output file is still invalid? Why FFMPEG's output uses deprecated "A_QUICKTIME/QDM2" as Audio Codec ID insted of just "A_QUICKTIME" like mosu wrote? -- Ticket URL: <https://trac.ffmpeg.org/ticket/3256#comment:9> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
