RTP/RTSP and MPEG4-AAC audio
- preliminary support for mpeg4-aac rtp payload (no interleaving support) - use udp transport as default (makes more sense with rtp, doesn't it ?) - some code factorization, so adding support for new rtp payload will be easier (I hope ;-) patch by (Romain DEGEZ: romain degez, smartjog com) Originally committed as revision 4306 to svn://svn.ffmpeg.org/ffmpeg/trunk
