SIP SIMPLE Client SDK

h1. WIPVideo

Notes while video is a work in progress.

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

export CFLAGS=`pkg-config --cflags x264`

export LDFLAGS=`pkg-config --libs x264`

./configure --enable-shared --disable-static --enable-memalign-hack --enable-gpl --enable-libx264 --prefix=$MY_VIDEO_LIBS

make

make install

# Clear CFLAGS and LDFLAGS

unset CFLAGS

unset LDFLAGS

</pre>

h3. SDL

<pre>

./configure --disable-audio --prefix=$MY_VIDEO_LIBS

make
