VFW Capture support
by ramiro＠lisha.ufsc.br 23 Oct '07

23 Oct '07

Hello, First attempt for VFW capture support in Windows. For testing purposes only! Enable it with: ./configure --enable-memalign-hack --enable-vfw-cap It prints lots of (somewhat useless) debug messages. Image is upside down =). I just have to find the right PIX_FMT and width/height... I'm way too tired to look at that now. Note: Run this FFmpeg from Windows' command prompts (cmd or command)! *Not MSys!*. This patch includes the patch I sent to ffmpeg-devel for interactive support for Windows. You must kill it with 'q' or Ctrl+C, or else the capture device won't be released, and you'll have to reboot Windows to get it back. MSys doesn't capture 'q' nor Ctrl+C, so it's doomed to make you loose control of the device. Ramiro Polla

I have an video file which has the following information in VLC Stream 0 - mpga Stream 1 - mpgv Stream 2 - cvd Stream 3 - a52 I believe this is a muxed mpeg1 file...when I run ffmpeg to create an flv, the encoder exits with an error message, the output follows, if anyone has any ideas as to why this happens, or if this is a known issue I'd greatly appreciate any feedback. ffmpeg -i input.mpg -f flv -r 30 -b 300k -ab 32 -ar 22050 -qmin 2 -qmax 15 -cmp 2 -subcmp 2 -g 150 -async 2 mpegfail.flv FFmpeg version SVN-r8757, Copyright (c) 2000-2007 Fabrice Bellard, et al. configuration: --prefix=/Users/Asli/CODE/ffmpeg/installed --enable-libmp3lame --enable-gpl --disable-vhook --extra-cflags=-I /Users/Asli/CODE/lame/installed/include --extra-ldflags=-L/Users/Asli/CODE/lame/installed/lib libavutil version: 49.4.0 libavcodec version: 51.40.4 libavformat version: 51.12.1 built on Apr 18 2007 18:32:06, gcc: 4.0.1 (Apple Computer, Inc. build 5367) Input #0, mpeg, from '/Users/Asli/Desktop/failing encoder 2/523032-9006fe9657181e29.mpg': Duration: 00:00:13.5, start: 0.122878, bitrate: 6257 kb/s Stream #0.0[0x99]: Audio: dca Stream #0.1[0x1e0]: Video: mpeg1video, yuv420p, 640x480, 104857 kb/s, 24.00 fps(r) Stream #0.2[0x1c0]: Audio: mp2, 44100 Hz, mono, 96 kb/s Output #0, flv, to '/Users/Asli/Desktop/mpegfail.flv': Stream #0.0: Video: flv, yuv420p, 640x480, q=2-15, 300 kb/s, 30.00 fps(c) Stream #0.1: Audio: mp3, 22050 Hz, mono, 0 kb/s Stream mapping: Stream #0.1 -> #0.0 Stream #0.0 -> #0.1 Press [q] to stop encoding [dca @ 0x3c17f4]Not a DCA frame= 0kB time=13.1 bitrate= 0.2kbits/s Error while decoding stream #0.0 frame= 408 fps= 70 q=31.0 Lsize= 1250kB time=0.1 bitrate=131240.7kbits/s video:935kB audio:0kB global headers:0kB muxing overhead 33.635186% AB _________________________________________________________________ PC Magazine?s 2007 editors? choice for best Web mail?award-winning Windows Live Hotmail. http://imagine-windowslive.com/hotmail/?locale=en-us&ocid=TXT_TAGHM_migrati…

ffmpeg ffsvq3 codec cannot decode video in .mov file
by sergemp＠mail.ru 05 Aug '07

05 Aug '07

Hello, ffmpeg-user. Initially it was an mplayer issue. But as far as it's related to ffmpeg codec I was suggested to write here. I tried to play with mplayer this file: http://www.iwamamoscow.ru/i/video/other/mountaindew_seagal.mov size: 4895360 It's played fine with -vfm qtvideo. In that case it's played with: Selected video codec: [qtsvq3] vfm: qtvideo (Win32/QuickTime SVQ3 decoder) Selected audio codec: [ffqdm2] afm: ffmpeg (FFmpeg QDM2 audio decoder) But without that switch mplayer tries to use ffsvq3 codec. And it prints a lot of errors instead of video (see log below). I've also rechecked it with first ffmpeg.exe that I found: ffmpeg.exe -i mounta~1.mov out.avi Start of ffmpeg log (stderr only - it prints everything to stderr somewhy): ========================================================================== FFmpeg version SVN-r8564, Copyright (c) 2000-2007 Fabrice Bellard, et al. configuration: --enable-gpl --enable-pp --enable-swscaler --enable-pthreads --enable-liba52 --enable-avisynth --enable-libdts --enable-libfaac --enable-libfaad --enable-libgsm --enable-libmp3lame --enable-libnut --enable-libogg --enable-libtheora --enable-libvorbis --enable-x264 --enable-xvid --enable-amr_nb --enable-amr_wb --cpu=i686 --enable-memalign-hack --extra-ldflags=-static libavutil version: 49.4.0 libavcodec version: 51.40.2 libavformat version: 51.11.0 built on Mar 31 2007 16:35:11, gcc: 4.3.0 20070126 (experimental) Seems stream 0 codec frame rate differs from container frame rate: 2997.00 (2997/1) -> 29.97 (30000/1001) Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'mounta~1.mov': Duration: 00:01:00.5, start: 0.000000, bitrate: 647 kb/s Stream #0.0(eng): Video: svq3, yuv420p, 320x240, 29.97 fps(r) Stream #0.1(eng): Audio: qdm2, 44100 Hz, mono Stream #0.2(eng): Video: mjpeg, yuvj444p, 320x240, 15.00 fps(r) Output #0, avi, to 'out.avi': Stream #0.0: Video: mpeg4, yuv420p, 320x240, q=2-31, 200 kb/s, 15.00 fps(c) Stream #0.1: Audio: mp2, 44100 Hz, mono, 64 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 [mpeg4 @ 009D4840]removing common factors from framerate Press [q] to stop encoding [svq3 @ 009D4840]luma prediction:2544 [svq3 @ 009D4840]error while decoding MB 0 0 Error while decoding stream #0.0 [svq3 @ 009D4840]luma prediction:1760 [svq3 @ 009D4840]error while decoding MB 0 0 Error while decoding stream #0.0 [svq3 @ 009D4840]top block unavailable for requested intra mode at 5 0 [svq3 @ 009D4840]check_intra_pred_mode = -1 [svq3 @ 009D4840]error while decoding MB 5 0 Error while decoding stream #0.0 [svq3 @ 009D4840]unsupported slice header (FF) Error while decoding stream #0.0 [svq3 @ 009D4840]left block unavailable for requested intra mode at 0 0 [svq3 @ 009D4840]check_intra_pred_mode = -1 [svq3 @ 009D4840]error while decoding MB 0 0 Error while decoding stream #0.0 [svq3 @ 009D4840]left block unavailable for requested intra mode at 0 0 [svq3 @ 009D4840]check_intra_pred_mode = -1 [svq3 @ 009D4840]error while decoding MB 0 0 Error while decoding stream #0.0 [svq3 @ 009D4840]error while decoding MB 0 0 Error while decoding stream #0.0 [svq3 @ 009D4840]top block unavailable for requested intra mode at 3 0 [svq3 @ 009D4840]check_intra_pred_mode = -1 [svq3 @ 009D4840]error while decoding MB 3 0 Error while decoding stream #0.0 [svq3 @ 009D4840]unsupported slice header (FF) Error while decoding stream #0.0 [svq3 @ 009D4840]top block unavailable for requested intra mode at 3 0 [svq3 @ 009D4840]check_intra_pred_mode = -1 [svq3 @ 009D4840]error while decoding MB 3 0 Error while decoding stream #0.0 [svq3 @ 009D4840]top block unavailable for requested intra mode at 3 0 [svq3 @ 009D4840]check_intra_pred_mode = -1 [svq3 @ 009D4840]error while decoding MB 3 0 Error while decoding stream #0.0 [svq3 @ 009D4840]top block unavailable for requested intra mode at 3 0 [svq3 @ 009D4840]check_intra_pred_mode = -1 [svq3 @ 009D4840]error while decoding MB 3 0 Error while decoding stream #0.0 [svq3 @ 009D4840]top block unavailable for requested intra mode at 4 0 [svq3 @ 009D4840]check_intra_pred_mode = -1 [svq3 @ 009D4840]error while decoding MB 4 0 Error while decoding stream #0.0 ... ========================================================================== Start of mplayer log (stderr only): ========================================================================== [svq3 @ 00CB5670]luma prediction:2544 [svq3 @ 00CB5670]error while decoding MB 0 0 Error while decoding frame!

How correctly convert animated GIF to FLV?
by rimling＠gmail.com 10 Jun '07

10 Jun '07

Hi all. I am try to convert animated GIF to FLV and on some images receive troubles. Frames with transparency sometime coming black in transparent area, i.e. lost transparency. Long time fighting with that, using gifsicle, read forums and this maillist. At the end solution was found. It is a optimizing GIF with ImageMagick before converting to FLV: convert original.gif -coalesce out.gif after this optimizing procedure do convert: ffmpeg -f gif -i out.gif result.flv And than all right. But may be somebody know more right path?

ogg support
by richard.bennett＠skynet.be 08 Jun '07

08 Jun '07

Hi, Could someone please confirm whether the current CVS version of FFMpeg supports converting ogg video to avi or fla? I tried to do it using the version of FFMpeg supplied with Ubuntu feisty (FFmpeg version SVN-rUNKNOWN, built on Jan 28 2007 22:48:38), and the resulting files were 0 size for flv, and only audio for avi. I'm happy to compile from source, but it would help if I knew if the feature was supported or not, or if I am using the wrong syntax. The command I used was simply: ffmpeg -i clip.ogg clip.avi Thanks, Richard.

OGG THEORA/VORBIS TO FLV AUDIO/VIDEO SYNCHONIZATION ISSUES
by jmcveigh＠kidsco.ca 08 Jun '07

08 Jun '07

Hello; I produce many stop-motion animations starring toy Lego characters. Videos can be viewed at http://www.brickfilms.com/ . I must regularily convert from OGG THEORA/OGG VORBIS to FLV to place the files on a new website. I can successfully convert the file, but there are audio/video synchronization issues. The audio is lagging a few seconds behind. I would truly appreciate your assistance. Thank you for your time. Here is some more information about my setup: ffmpeg -i input.flv -ar 44100 output.flv FFmpeg version SVN-r8852, Copyright (c) 2000-2007 Fabrice Bellard, et al. configuration: --enable-libmp3lame --enable-libogg --enable-libtheora --enable-libvorbis libavutil version: 49.4.0 libavcodec version: 51.40.4 libavformat version: 51.12.1 built on Apr 27 2007 15:06:54, gcc: 4.1.1 20061011 (Red Hat 4.1.1-30) Running Fedora Core 6 If more details are required, please let me know.
