Revision 6 (Saúl Ibarra Corretgé, 08/28/2013 05:13 PM) → Revision 7/43 (Saúl Ibarra Corretgé, 08/28/2013 05:13 PM)
h1. WIPVideo
Notes while video is a work in progress. Repository: http://devel.ag-projects.com/cgi-bin/darcsweb.cgi?r=saul/python-sipsimple-video;a=summary
h2. Dependencies
The following dependencies are required to build PJSIP with video support (including H264)
* SDL 2
* ffmpeg (libavformat, libswscale, libavcodec, libavutil)
* libx264
Versions I have tried:
* SDL (2.0.0-7655)
* ffmpeg (2.0 release)
* libx264 (snapshot-20130806-2245-stable)
h2. Patches
If the above versions are used, PJSIP needs to be patched with the attached patch (avcodec.diff) or it won't compile. This does not occur when compiling it against the latest library versions on Debian unstable.
h2. Compiling dependencies
All dependencies will be compiled to a directory in the user's HOME directory:
<pre>
export MY_VIDEO_LIBS=$HOME/work/ag-projects/video/local
</pre>
h3. libx264
<pre>
./configure --enable-shared --disable-avs --disable-swscale --disable-lavf --disable-ffms --disable-gpac --prefix=$MY_VIDEO_LIBS
make
make install
</pre>
h3. ffmpeg
<pre>
# Some exports
export PKG_CONFIG_PATH=$MY_VIDEO_LIBS/lib/pkgconfig
./configure --enable-shared --disable-static --enable-memalign-hack --enable-gpl --enable-libx264 --prefix=$MY_VIDEO_LIBS
./configure --enable-shared --disable-static --enable-memalign-hack --enable-gpl --enable-libx264 --prefix=$MY_VIDEO_LIBS --extra-cflags="`pkg-config --cflags x264`" --extra-ldflags="`pkg-config --libs x264`"
make
make install
</pre>
h3. SDL
<pre>
./configure --disable-audio --prefix=$MY_VIDEO_LIBS
make
make install
</pre>
h2. Compiling PJSIP (pjsua, for testing)
<pre>
svn co http://svn.pjsip.org/repos/pjproject/trunk pjsip
cd pjsip
echo "#define PJMEDIA_HAS_VIDEO 1" > pjlib/include/pj/config_site.h
./configure --with-sdl=$MY_VIDEO_LIBS --with-ffmpeg=$MY_VIDEO_LIBS
make dep
make
# pjsua will be located in pjsip-apps/bin/
</pre>
