That means dsputil.o file had size 2.1MB with debug info. For example in Commit:22180e7a5a39f8a77498fcbce54368ecc408df8f. After the rebase onto actual master the size of dsputil.o increased to 4.7MB, which seems really wierd to me. Maybe it can be a gcc bug/feature as it is connected with optimization (--disable-optimizations reduces the size again but the speed ...). Unfortunately I can't track the commit when this situation appeared I'm only sure that the commit mentioned above is OK. I'm using gcc 4.4.5 for arm-unknown-elf target on windows/mingw. $ arm-unknown-elf-gcc -v Using built-in specs.

When transcoded with FFmpeg, the resulting file is non-interleaved, i.e. the 15 seconds of sound come first (without picture). MPlayer's mpegts demuxer indicates that the stream does start with mostly identical timestamps for audio and video (but plays the video too fast). FFmpeg seems to believe that audio starts with timestamps ~130 and video with ~260. {{{ $ ffmpeg -i ts720p_i_fr.ts -qscale 5 out.avi ffmpeg version N-32263-g3584b01, Copyright (c) 2000-2011 the FFmpeg developers built on Sep 1 2011 12:14:35 with gcc 4.5.3 configuration: --cc='/usr/local/gcc-4.5.3/bin/gcc -m32' libavutil 51. 14. 0 / 51. 14. 0 libavcodec 53. 12. 0 / 53. 12. 0 libavformat 53. 10. 0 / 53. 10. 0 libavdevice 53. 3. 0 / 53. 3. 0 libavfilter 2. 37. 0 / 2. 37. 0 libswscale 2. 0. 0 / 2. 0. 0 [mpegts @ 0x8c963a0] Continuity Check Failed [mpegts @ 0x8c963a0] max_analyze_duration 5000000 reached at 5016000 [mpegts @ 0x8c963a0] PES packet size mismatch Input #0, mpegts, from 'ts720p_i_fr.ts': Duration: 00:00:14.61, start: 130.272000, bitrate: 9237 kb/s Program 16 Metadata: service_name : PMR COBRA 1213 service_provider: PMR Stream #0.0[0x109]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], 60 fps, 60 tbr, 90k tbn, 120 tbc Stream #0.1[0x103]: Audio: mp2 ([4][0][0][0] / 0x0004), 48000 Hz, stereo, s16, 128 kb/s [buffer @ 0x8d86a00] w:1280 h:720 pixfmt:yuv420p tb:1/1000000 sar:1/1 sws_param: Incompatible sample format 's16' for codec 'ac3', auto-selecting format 'flt' Output #0, avi, to 'out.avi': Metadata: ISFT : Lavf53.10.0 Stream #0.0: Video: mpeg4 (FMP4 / 0x34504D46), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], q=2-31, 200 kb/s, 60 tbn, 60 tbc Stream #0.1: Audio: ac3 ([0] [0][0] / 0x2000), 48000 Hz, stereo, flt, 128 kb/s Stream mapping: Stream #0.0 -> #0.0 (h264 -> mpeg4) Stream #0.1 -> #0.1 (mp2 -> ac3) Press [q] to stop, [?] for help [mpegts @ 0x8c963a0] Continuity Check Failed Last message repeated 1 times 236kB time=00:00:14.27 bitrate= 135.6kbits/s [mpegts @ 0x8c963a0] PES packet size mismatch [h264 @ 0x8c9b6e0] error while decoding MB 76 41, bytestream (-5) [h264 @ 0x8c9b6e0] concealing 293 DC, 293 AC, 293 MV errors frame= 852 fps= 31 q=5.0 Lsize= 177161kB time=00:00:14.62 bitrate=99241.4kbits/s video:12002kB audio:228kB global headers:0kB muxing overhead 1348.534109% }}} -- Ticket URL: <https://avcodec.org/trac/ffmpeg/ticket/424> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

The file contains left, center and right stream, FFmpeg currently warns that the channel layout is unsupported. It is simple to set the correct channel layout (trivial patch attached), but the problem is that the file has channel order "center, left, right" (MPEG-3-0-B), so that FFmpeg maps the left channel to the right, the right channel to center and the center channel to the left channel on decoding. How can a demuxer tell the pcm decoder that the decoder has to reorder channels? {{{ ffmpeg -i MPEG30B.caf FFmpeg version git-N-29301-gab15726, Copyright (c) 2000-2011 the FFmpeg developers built on Apr 23 2011 10:48:07 with gcc 4.5.2 configuration: --cc=/usr/local/gcc-4.5.2/bin/gcc --enable-gpl --enable- libcelt libavutil 51. 0. 0 / 51. 0. 0 libavcodec 53. 1. 0 / 53. 1. 0 libavformat 53. 0. 1 / 53. 0. 1 libavdevice 53. 0. 0 / 53. 0. 0 libavfilter 2. 0. 0 / 2. 0. 0 libswscale 0. 13. 0 / 0. 13. 0 [caf @ 0x12a0ae0] Unknown channel layout.

#386: Missing audio and subtitle streams in vob file --------------------------+-------------------------- Reporter: Aztek | Type: defect Status: new | Priority: normal Component: undetermined | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced: 0 Analyzed: 0 | --------------------------+-------------------------- ==Problem== I want to transcode a VOB into x264 on a headless Debian stable server. `mediainfo` reports a number of audio tracks and subtitle streams. `ffprobe` (and `ffmpeg`) reports no audio nor subtitle stream. I'd like to provide the VOB file but I can't for legal reasons. I tried to cut the file (with `dd`) to give a "small sample" but `ffprobe` behaviour seems to depend on the length of the resulting VOB file (with 10MB, all the audio streams are found but non of the subtitles streams for instance; at 500MB, just one audio stream is available). `ffplay` can successfully play the file but I am not sure I can actually choose the audio stream I want. I can provide anything you might consider usefull. Thanks for your help. ==Important note== I am sure all the VOB files I concatenated actually contained parts of the movie (all of those were needed otherwise parts of the movie just disappear). `mediainfo` reports a menu stream (and that might be the reason why `ffprobe` reports wrong streams). But as I said, every VOB files I used are needed. So, if you know any way to extract precisely menu-related stuff from the VOB, please let me know. (I'd like to avoid mplayer or avidemux: those depend on too many useless things like dbus or avahi) ==Software version== ffprobe 0.8 libavutil 51. 9. 1 libavcodec 53. 7. 0 libavformat 53. 4. 0
