RTP module cannot feed muxed streams to RTSP server module
#rtp stream-out module is currently not handling muxed streams correcly when it is opening an RTSP server. An attempt to use e.g. MPEG-TS together with RTSP fails, because the RTSP server only sees the ES, and not the muxed TS stream. VLC builds a UDP multicast MPEG-TS stream, but the setup RTSP server thinks it is getting two ES streams.
