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

Mpeg4 visual simpel profile and ffmpeg
by Kim.Schulz＠csr.com 13 Dec '06

13 Dec '06

Hi I want to decode a rtp stream of mpeg4 visual simple data, but I am not sure which codec id to use for this. A helpful guy in irc told me to use CODEC_ID_MPEG4 and then do the additional setup in the codec context. But what settings should I set in the context? I only have very limited information about the video stream as it arrives - Level (1-3) and the fact that it is MPEG4 visual simple profile. The stream follows RFC 3016 and I have the entire setup ready to grep the frames and get the video payload out of it - simply need to setup the codec. Anyone here who has worked with this and know how to do set it up? Maybe even have a short example. -- Med venlig hilsen / Best regards Kim Schulz To access the latest news from CSR copy this link into a web browser: http://www.csr.com/email_sig.php

Compile error in h264.c on Mac OS X 10.4.8
by adam.block＠gmail.com 08 Dec '06

08 Dec '06

Hi. I am trying to compile trunk (rev. 6997) for the Mac on OSX 10.4.8. (Previously I was running 6375 with no problems but I need the fix that allows piping into ffmpeg from STDIN.) Lame is version 3.97. I got the dist from svn, then added the amr_float and amrwb_float directories to libavcodec (I need to decode 3gpp video). I ran configure: ./configure --enable-mp3lame --enable-shared --disable-mmx --disable-vhook --enable-amr_nb --enable-amr_wb With --disable-mmx and --disable-vhook as recommended for Intel Mac. Everything made fine until: cc -I"/Users/adamblock/src/ffmpeg"/libswscale -DHAVE_AV_CONFIG_H -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_ISOC9X_SOURCE -I"/Users/adamblock/src/ffmpeg" -I"/Users/adamblock/src/ffmpeg" -I"/Users/adamblock/src/ffmpeg"/libavutil -no-cpp-precomp -pipe -force_cpusubtype_ALL -Wno-sign-compare -fomit-frame-pointer -g -Wdeclaration-after-statement -Wall -Wno-switch -Wdisabled-optimization -Wpointer-arith -Wredundant-decls -O3 -c -o h264.o h264.c h264.c: In function 'hl_decode_mb': h264.c:3661: warning: suggest parentheses around arithmetic in operand of ^ h264.c:3667: warning: suggest parentheses around arithmetic in operand of ^ h264.c: In function 'decode_unregistered_user_data': h264.c:7598: warning: pointer targets in passing argument 1 of 'sscanf' differ in signedness cabac.h: In function 'decode_cabac_residual': cabac.h:636: error: PIC register '%ebx' clobbered in 'asm' cabac.h:636: error: PIC register '%ebx' clobbered in 'asm' h264.c: At top level: cabac.h:109: warning: 'put_cabac_static' defined but not used cabac.h:155: warning: 'put_cabac_terminate' defined but not used cabac.h:183: warning: 'put_cabac_u' defined but not used cabac.h:218: warning: 'put_cabac_ueg' defined but not used cabac.h:808: warning: 'get_cabac_u' defined but not used cabac.h:824: warning: 'get_cabac_ueg' defined but not used make[1]: *** [h264.o] Error 1 make: *** [lib] Error 2 Any thoughts? If you suggest changes to headers, compile flags, etc. please be explicit about how to make the changes; I'm good as far as configure flags and pretty hopeless after that. :) Thanks!!! /afb

Hello, Can anyone tell me why certain quicktime (.mov) formats do not seem to convert to FLV. Do I need to flag --enable-x264 when I complile ffmpeg for Quicktime support? If anyone can let me know what config options I need to focus on to get Quicktime codec support in ffmpeg - I would really appreciate it. Thank you, Ryan
