Gpac MPEG-4 Systems library and headers
WWW: http://gpac.sourceforge.net/
This is a small portion of gpac, only headers and mpeg4 systems library
due to a chicken and egg problem similar to mpeg4ip, faad, and mpeg4ip-libmp4v2
x264 wants m4systems lib for mpeg4 output, gpac wants ffmpeg, next version
of ffmpeg wants x264.
