SIP SIMPLE Client SDK

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

# If a 32bit build is wanted, then run this configure instead:

./configure --host=i386-apple-darwin --enable-shared --disable-avs --disable-swscale --disable-lavf --disable-ffms --disable-gpac --prefix=$MY_VIDEO_LIBS

</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 --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>
