#252(avformat:new): matroska/rawvideo decoding gives invalid pixel format string -1 @ buffer

#252: matroska/rawvideo decoding gives invalid pixel format string -1 @ buffer ---------------------------------------+--------------------- Reporter: kenney | Type: defect Status: new | Priority: normal Component: avformat | Version: git Keywords: matroska rawvideo pix_fmt | Blocked By: Blocking: | Reproduced: 0 Analyzed: 0 | ---------------------------------------+--------------------- The error: {{{ [buffer @ 00000000003F8E80] Invalid pixel format string '-1' Error opening filters! }}} I am converting an mkv file with a V_UNCOMPRESSED or -vcodec rawvideo video stream to any other stream, let's say .avi. First create the .mkv with rawvideo using any (short) valid video file, such as an avi: $ ffmpeg -i goodfile.avi -vcodec rawvideo test.mkv [See output 1 below] Next, I convert the mkv, which doesn't play ofcourse, back to avi: $ ffmpeg -i test.mkv test.avi [See output 2 below] The first step is just for you guys to be able to test this. I need to be able to pipe uncompressed frames with a timecode to ffmpeg.exe commandline, and mkv seems one of the only formats that allows this, as the rest either doesn't have VFR or uncompressed frames. And no, I cannot use the libs. Here is '''output 1''', no problems here: {{{ ffmpeg version git-N-30155-g01a73d6, Copyright (c) 2000-2011 the FFmpeg developers built on May 23 2011 03:47:41 with gcc 4.5.3 configuration: --enable-gpl --enable-version3 --enable-memalign-hack --enable-runtime-cpudetect --enable-avisynth --enable-bzlib --enable- frei0r --enable-libopencore-amrnb --enable-libopencore-amrwb --enable- libfreetype --enable-libgsm --enable-libmp3lame --enable-libopenjpeg --enable-librtmp --enable-libschroedinger --enable-libspeex --enable- libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable- libxavs --enable-libxvid --enable-zlib --pkg-config=pkg-config libavutil 51. 2. 1 / 51. 2. 1 libavcodec 53. 6. 0 / 53. 6. 0 libavformat 53. 2. 0 / 53. 2. 0 libavdevice 53. 0. 0 / 53. 0. 0 libavfilter 2. 10. 0 / 2. 10. 0 libswscale 0. 14. 0 / 0. 14. 0 libpostproc 51. 2. 0 / 51. 2. 0 [avi @ 000000000033A0C0] non-interleaved AVI Input #0, avi, from 'goodfile.avi': Duration: 00:00:02.54, start: 0.000000, bitrate: 298619 kb/s Stream #0.0: Video: rawvideo, bgr24, 960x540, 24 tbr, 24 tbn, 24 tbc [buffer @ 000000000033CD60] w:960 h:540 pixfmt:bgr24 tb:1/1000000 sar:0/1 sws_param: Output #0, matroska, to 'test.mkv': Metadata: encoder : Lavf53.2.0 Stream #0.0: Video: rawvideo, bgr24, 960x540, q=2-31, 200 kb/s, 1k tbn, 25 tbc Stream mapping: Stream #0.0 -> #0.0 Press [q] to stop, [?] for help frame= 60 fps= 0 q=0.0 size= 91112kB time=2.40 bitrate=310996.0kbits/s frame= 61 fps= 0 q=0.0 Lsize= 92647kB time=2.44 bitrate=311049.8kbits/s video:92644kB audio:0kB global headers:0kB muxing overhead 0.003153% }}} And here is '''output 2''', the problem: {{{ ffmpeg version git-N-30155-g01a73d6, Copyright (c) 2000-2011 the FFmpeg developers built on May 23 2011 03:47:41 with gcc 4.5.3 configuration: --enable-gpl --enable-version3 --enable-memalign-hack --enable-runtime-cpudetect --enable-avisynth --enable-bzlib --enable- frei0r --enable-libopencore-amrnb --enable-libopencore-amrwb --enable- libfreetype --enable-libgsm --enable-libmp3lame --enable-libopenjpeg --enable-librtmp --enable-libschroedinger --enable-libspeex --enable- libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable- libxavs --enable-libxvid --enable-zlib --pkg-config=pkg-config libavutil 51. 2. 1 / 51. 2. 1 libavcodec 53. 6. 0 / 53. 6. 0 libavformat 53. 2. 0 / 53. 2. 0 libavdevice 53. 0. 0 / 53. 0. 0 libavfilter 2. 10. 0 / 2. 10. 0 libswscale 0. 14. 0 / 0. 14. 0 libpostproc 51. 2. 0 / 51. 2. 0 [matroska,webm @ 00000000003F9F20] Estimating duration from bitrate, this may be inaccurate Input #0, matroska,webm, from 'test.mkv': Metadata: ENCODER : Lavf53.2.0 Duration: 00:00:02.44, start: 0.000000, bitrate: N/A Stream #0.0: Video: rawvideo, 960x540, PAR 1:1 DAR 16:9, 25 fps, 25 tbr, 1k tbn, 25 tbc (default) [buffer @ 00000000003F8E80] Invalid pixel format string '-1' Error opening filters! }}} Now, I realize that there is nowhere in the file stored what the pixel format is. Even when I specify -pix_fmt rgb24 I get this error. Also, according to the specs ( http://www.matroska.org/technical/specs/index.html ) there is a ColourSpace field that might be used but is not written. Btw if there is a workaround to this by specifying internal filters like -vf buffer or something in the mean time (I tried..), I'd appreciate it;) -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/252> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#67(undetermined:new): grey images (and video) when using -ss
by FFmpeg 27 Sep '12

#67: grey images (and video) when using -ss --------------------------+-------------------------- Reporter: aphid | Type: defect Status: new | Priority: normal Component: undetermined | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced: 0 Analyzed: 0 | --------------------------+-------------------------- I'm splitting mpeg2 video, as captured from a capture card (and will ultimately be applying some libavfilter stuff for trademark obfuscation, but that is peripheral to this report). I've recently upgraded from ffmpeg that was probably 1.5 years or so old, and splitting fine both for still images and video, to git. When creating images with -ss, output is solid grey unless -ss happens to fall exactly on a keyframe. When creating video, it starts gray, transitions to gray+artifacts and then looks fine after the first keyframe.

The file contains several frames with ~900x700 resolution and one frame 1920x1080 (which does not to contradict to H.264 specification). Some time ago there was similar issue (issue2393 in old tracker) and it was successfully fixed. The bug was introduced again after git revision aecd0a4 (probably with ffmpeg-mt merge). If it is required I'll find the exact revision when the bug was introduced. Platform is WIN32.
