#1806: Audio/video stream order reversed in remuxed VOB files ------------------------------------+------------------------------------ Reporter: paulbu | Owner: Type: defect | Status: open Priority: normal | Component: avformat Version: git-master | Resolution: Keywords: mpegps | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ------------------------------------+------------------------------------ Comment (by wim_arbor): AFAIK mpeg ps files do not contain stream numbers other than the stream ID. The Stream ID for video streams start with 0xE0, MP2 audio streams start with 0xC0, AC3 is encoded in private stream 1 (0xBD) with substream number starting at 0x80. So the stream id for mpeg ps depends on the format and is independent of the stream number ffmpeg uses internally. That would mean the problem is not the stream number of the video stream in the file used for dvdauthor, and ffmpeg is not doing any wrong stream mapping. If I convert the attached file with this commandline: {{{ ffmpeg -i test-ffmpeg.vob -target pal-dvd -codec copy out.vob }}} I am able to create a DVD with dvdauthor 0.6.9 but not with dvdauthor 0.7.1. (I did not test other versions). This could mean an issue with dvdauthor. Note when I delay the audiostream, both versions of dvdauthor work. {{{ ffmpeg -i test-ffmpeg.vob -itsoffset 1.5 -i test-ffmpeg.vob -map 1:v -map 0:a -target pal-dvd -codec copy out2.vob }}} Indeed ffprobe displays swapped video and audio stream number; {{{ Input #0, mpeg, from 'out.vob': Duration: 00:00:05.59, start: 0.500000, bitrate: 2759 kb/s Stream #0:0[0x1bf]: Data: dvd_nav_packet Stream #0:1[0x80]: Audio: ac3, 48000 Hz, stereo, fltp, 256 kb/s Stream #0:2[0x1e0]: Video: mpeg2video (Main), yuv420p(tv), 352x576 [SAR 24:11 DAR 4:3], max. 3060 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc }}} {{{ Input #0, mpeg, from 'out2.vob': Duration: 00:00:06.43, start: 0.620000, bitrate: 2385 kb/s Stream #0:0[0x1bf]: Data: dvd_nav_packet Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv), 352x576 [SAR 24:11 DAR 4:3], max. 3060 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc Stream #0:2[0x80]: Audio: ac3, 48000 Hz, stereo, fltp, 256 kb/s }}} That is a problem in ffmpeg too if you refer to a stream with a number (like 0:1). -- Ticket URL: <https://trac.ffmpeg.org/ticket/1806#comment:4> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

Also a full backtrace with linenumbers and disassembly of the crashing place and register values could help to better understand this And the inability of carl to reproduce this might be due to differing libvo-aacenc versions (but iam just guessing here) With which libvo-aacenc version does this happen?
