I need to obtain the sizes of the I, P and B frames of the video of a DVD. Is this possible with ffmpeg? _________________________________________________________________ Express yourself instantly with MSN Messenger!

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

Encoding grey pattern to WMV causes green square artefacts in Windows Media Player
by vanista＠gmail.com 31 Aug '07

31 Aug '07

Uploaded files to : ftp://upload.mplayerhq.hu/MPlayer/incoming/wmv_green_squares_wmp Subject : Transcoding grey static video to WMV causes green square artefacts in Windows Media Player I transcoded a simple GIF animation to WMV. Part of the picture displayed as green square artefacts during playback in Windows Media Player. I've extracted and expanded this part of the picture. It features grey pixels with somewhat high frequencies (noise). This new samples easily produces the problem in WMP. The same output is decoded fine with libavcodec and all players using it. Using Windows Media Encoder on the same input doesn't produce the problem. I also figured that filtering out the high frequencies would fix the problem. For example, using GStreamer's postproc_lowpass5 filter with scope=2 quality=0. ffmpeg -i grey.avi -vcodec wmv2 ffout.wmv FFmpeg version SVN-r9376, Copyright (c) 2000-2007 Fabrice Bellard, et al. configuration: --prefix=/opt/sherdev/MPlayer/1.0rc1 --enable-gpl --disable-strip --disable-mmx libavutil version: 49.4.0 libavcodec version: 51.40.4 libavformat version: 51.12.1 built on Jun 20 2007 14:58:35, gcc: 3.4.6 Input #0, avi, from 'grey.avi': Duration: 00:00:02.0, start: 0.000000, bitrate: 93 kb/s Stream #0.0: Video: rawvideo, yuv420p, 96x80, 1.00 fps(r) Output #0, asf, to 'ffout.wmv': Stream #0.0: Video: wmv2, yuv420p, 96x80, q=2-31, 200 kb/s, 1.00 fps(c) Stream mapping: Stream #0.0 -> #0.0 Compiler did not align stack variables.

Build ffmpeg with external library support using mingw32
by spendino＠cantoche.com 16 Aug '07

16 Aug '07

Hello everybody. As far as I know ffmpeg, amr support has recently changed - this codec is now compiled as an external library-. I'd like to build ffmpeg with libamr-nb enabled and I experience troubles. Here is what I get : $ ./configure --enable-memalign-hack --enable-libamr-nb ERROR: libamrnb not found If you think configure made a mistake, make sure you are using the latest version from SVN. If the latest version fails, report the problem to the ffmpeg-devel at mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "config.err" produced by configure as this will help solving the problem. And here is my config.err check_lib zlib.h zlibVersion -lz check_header zlib.h check_cpp BEGIN /tmp/ffmpeg-conf-8495-1348-20764.c 1 #include <zlib.h> 2 int x; END /tmp/ffmpeg-conf-8495-1348-20764.c gcc -fomit-frame-pointer -E -o /tmp/ffmpeg-conf-23568-1348-24308.o /tmp/ffmpeg-conf-8495-1348-20764.c C:/DOCUME~1/Sylvain/LOCALS~1/Temp/ffmpeg-conf-8495-1348-20764.c:1:18: zlib.h: No such file or directory check_lib amrnb/interf_dec.h Speech_Decode_Frame_init -lamrnb -lm check_header amrnb/interf_dec.h check_cpp BEGIN /tmp/ffmpeg-conf-8495-1348-20764.c 1 #include <amrnb/interf_dec.h> 2 int x; END /tmp/ffmpeg-conf-8495-1348-20764.c gcc -fomit-frame-pointer -E -o /tmp/ffmpeg-conf-23568-1348-24308.o /tmp/ffmpeg-conf-8495-1348-20764.c C:/DOCUME~1/Sylvain/LOCALS~1/Temp/ffmpeg-conf-8495-1348-20764.c:1:30: amrnb/interf_dec.h: No such file or directory ERROR: libamrnb not found Please note that I am using : - mingw32 - libamrnb 6.1.0.3 - FFmpeg version SVN-r9197 ( libavutil version: 49.4.0 libavcodec version: 51.40.4 libavformat version: 51.12.1 ) However, both the zlib and the libamrnb are installed (they are located in /usr/local). Does someone know why these libs cannot be found ? Thanks in advance Sylvain

Problem converting AAC/MKV to AC3/MPEG
by bumph＠holyblasphemy.org 05 Aug '07

05 Aug '07

Hello, I am trying to transcode from H264 and AAC in a Matroska container to an MPEG-2 suitable for burning as a DVD-Video. The video is transcoded perfectly but the audio is not. The audio source is stereo but ffmpeg seems to think it is mono. The resulting AC3 audio is mono and slowed down (I guess by half.) How can I convince ffmpeg that the input audio is stereo and that it should produce a stereo audio output at the right speed? I am running Mac OS X 10.4 on a G4 PowerPC laptop. I checked out the latest version of FFmpeg from the Subversion repository less than an hour ago. I am using this command: ffmpeg -i Sample.mkv -target pal-dvd Sample.mpg And this is the output: FFmpeg version SVN-r9255, Copyright (c) 2000-2007 Fabrice Bellard, et al. configuration: --disable-vhook --enable-shared --enable-pthreads --enable-gpl --enable-pp --enable-x11grab --enable-libmp3lame --enable-libogg --enable-libvorbis --enable-libtheora --enable-libfaac --enable-libfaad --enable-libxvid --enable-libx264 --enable-liba52 libavutil version: 49.4.0 libavcodec version: 51.40.4 libavformat version: 51.12.1 built on Jun 8 2007 15:47:07, gcc: 4.0.1 (Apple Computer, Inc. build 5250) [matroska @ 0xeeb58]Ignoring seekhead entry for ID=0x1549a966 [matroska @ 0xeeb58]Ignoring seekhead entry for ID=0x1654ae6b [matroska @ 0xeeb58]Unknown entry 0x73a4 in info header [matroska @ 0xeeb58]Unknown track header entry 0x55aa - ignoring [matroska @ 0xeeb58]Unknown track header entry 0x23314f - ignoring [matroska @ 0xeeb58]Unknown track header entry 0x55ee - ignoring [matroska @ 0xeeb58]Unknown track header entry 0xaa - ignoring [matroska @ 0xeeb58]Unknown track header entry 0x55aa - ignoring [matroska @ 0xeeb58]Unknown track header entry 0x23314f - ignoring [matroska @ 0xeeb58]Unknown track header entry 0x55ee - ignoring [matroska @ 0xeeb58]Unknown track header entry 0xaa - ignoring Input #0, matroska, from 'Sample.mkv': Duration: 00:01:02.8, start: 0.000000, bitrate: N/A Stream #0.0: Video: h264, yuv420p, 720x400, 24.39 fps(r) Stream #0.1: Audio: mpeg4aac, 48000 Hz, mono Output #0, dvd, to 'Sample.mpg': Stream #0.0: Video: mpeg2video, yuv420p, 720x576, q=2-31, 6000 kb/s, 25.00 fps(c) Stream #0.1: Audio: ac3, 48000 Hz, mono, 448 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Press [q] to stop encoding frame= 1564 fps= 14 q=2.0 Lsize= 18826kB time=62.5 bitrate=2466.8kbits/s video:10848kB audio:6864kB global headers:0kB muxing overhead 6.293671% I tried specifying "-ac 2" as an option for the input but it made no difference. I tried specifying it for the output and it did produce stereo audio but it was very noisy and still slowed down. I have uploaded the sample that I am I trying to convert to ftp://upload.mplayerhq.hu/MPlayer/incoming/cc1625/ I'd be grateful if someone could tell me what I'm doing wrong. Thanks. Charles

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!

Mike, (Reply to Michel's email below) Many thanks for your help! Now have had a chance to read this... >> ffmpeg -v /dev/video0 -f avi -s 720x576 -an outfile.avi >> > > What version is this (BTW - that command wont work any version - in old > versions -v should be -vd) No idea. The version information annoyingly says "UNKNOWN" All I know this computer is running some flavour of Debian.

But since you dont have X, try v4lctl. Here's the docs I'm looking at: http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html#SEC3 No mention about -vc. Obviously, I'm looking at the wrong docs, but putting ffmpeg in google brings up ffmpeg.mplayerhq.hu which made me assume the ppl behind mplayer developed ffmpeg or something. Tried http://sourceforge.net/projects/ffmpeg/ - can't find any docs. Clicked on the homepage and it went to ffmpeg.mplayerhq.hu. I also searched various newsgroups. > Note that if you install just the X *client* libraries on the capture > machine, you should be able to use xawtv there with display on your > usual desktop. Never got X forwarding to work perfect to be honest with you, but will try. I've done the basics like enable X forwarding in the sshd_config file, and start X forwarding using "ssh -X piers at 192.168.1.4" but I *always* get errors like: piers at video-test-a:~$ xawtv This is xawtv-3.95.dfsg.1, running on Linux/i686 (2.6.15-1-686) Error: Can't open display: piers at video-test-a:~$ This is obviously due to a misconfiguration on my part somewhere, but I was never able to figure it out. But, this isn't the place or time to discuss X forwarding :) Thanks so very much for your help anyway! Regards - Piers
