thread on mailinglist for discussion. This patch also implements a RTSPServerType enum, which allows the RTSP to keep track of what kind of a stream we're handling: standard-compliant RTP or a proprietary derivative. This will be used in subsequent patches to implement more Realmedia-specific extensions required to receive and parse data coming from a Realmedia server. Originally committed as revision 15104 to svn://svn.ffmpeg.org/ffmpeg/trunk
