#3184(undetermined:new): sfd: de/muxing does not properly work for cri adx and ac3
#3184: sfd: de/muxing does not properly work for cri adx and ac3 -------------------------------------+------------------------------------- Reporter: Soukyuu | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: SFD (SofDec) is essentially mpeg1 video + adx audio (in later versions, also ac3 audio). ffplay plays the file fine - adx is being played in file as well as out of file. The files come directly from the Ar tonelico 2 game, so they are official and not corrupted. Demuxing: - video works - adx works - ac3 is being detected as adx, 0 channels, cannot be demuxed. Muxing: - m1v + adx = mpeg with m1v+broken mp3 - m1b + adx = mpeg with m1v+broken mp3+working ac3 How to reproduce: - Demuxing AC3 {{{ "D:\\Program Files\\ffmpeg-20131129-git-7ea9c4a- win64-static\\bin\\ffmpeg.exe" -i ".\\AT2_OP1D.SFD" -acodec copy -vn -map 0:1 -report -f ac3 "R:\\test.ac3" ffmpeg version N-58570-g7ea9c4a Copyright (c) 2000-2013 the FFmpeg developers built on Nov 28 2013 22:06:58 with gcc 4.8.2 (GCC) }}} - Muxing m1v + adx {{{ "D:\\Program Files\\ffmpeg-20131129-git-7ea9c4a- win64-static\\bin\\ffmpeg.exe" -i "R:\\AT2_OP01.m1v" -i "R:\\AT2_OP01.adx" -report -c copy -map 0:v:0 -map 1:a:0 -f mpeg "R:\\out.sfd" ffmpeg version N-58570-g7ea9c4a built on Nov 28 2013 22:06:58 with gcc 4.8.2 (GCC) }}} - Muxing m1v + adx + ac3 {{{ "D:\\Program Files\\ffmpeg-20131129-git-7ea9c4a- win64-static\\bin\\ffmpeg.exe" -i "R:\\AT2_OP1D.m1v" -i "R:\\AT2_OP1D.adx" -i "R:\\AT2_OP1D.ac3" -map 0:v:0 -map 1:a:0 -map 2:a:0 -acodec copy -vcodec copy -report -f mpeg out.sfd ffmpeg version N-58570-g7ea9c4a Copyright (c) 2000-2013 the FFmpeg developers built on Nov 28 2013 22:06:58 with gcc 4.8.2 (GCC) }}} The demuxing error probably comes from the fact sfd isn't really following the format and doing something along the lines of using an adx header for ac3 stream. The muxing error is beyond me though. ffmpeg -formats lists ADX as being muxable, I am also telling it to copy the codec, yet it still botches it to mp2. I mentioned this on the irc channel some time ago and was told that the actual muxing code is not there. Can provide samples if needed.

- ac3 is being detected as adx, 0 channels, cannot be demuxed.
Please provide a sample. Muxing sdf is not supported, if it is mentioned as supported, this would be a (separate) bug. Please consider providing the failing command line for ac3-in-sdf together with the complete, uncut console output, please do not compress the console output. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3184#comment:1> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

The sample is not fully uploaded, but I guess you already managed to reproduce it. By the way, sfd does not even seem to be defined as a separate format, so what I meant by "mentioned as supported" is muxing/demuxing adx (not sfd). The patch will only affect being unable to demux ac3, right? Should I make a separate issue/enhancement request to support proper sfd muxing? -- Ticket URL: <https://trac.ffmpeg.org/ticket/3184#comment:7> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
