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 make install </pre>
