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.

This is how to reproduce the problem:

on VLC (server side) start

whatever.mpg :sout=#rtp{dst=239.1.2.3,mux=ts,sdp=rtsp://your.ip.addr:8080/test}

on second VLC (client side) try

rtsp://your.ip.addr:8080/test

and you'll get:

main debug: looking for access_demux module: 1 candidate livedotcom debug: sdp=v=0 o=- 644537765000 1 IN IP4 127.0.0.1 s=NONE t=0 0 a=tool:vlc 0.8.5-svn-20060223-0000 c=IN IP4 239.1.2.3/1

(no m= line here, thus the SDP is invalid)

livedotcom error: PLAY failed No RTSP session is currently in progress

removed Status::works for me label

added Severity::normal label and removed Severity::major label

This isn't the only thing that's wrong. It seems that multicast isn't working AT ALL anymore in this module. Who has been breaking all this shit.

Also there are fprintf to stderr everywhere, and it doesn't support Aggregate mode RTSP.

(In [14541]) * Fix the rtp module to not create broken SDPs. muxed streams are unsupported in RTSP mode. fixes #452 (closed)

• commented a few fprintf, and changed some to msg_Dbg where possible.
• fixed a couple of spelling errors.
• this module really needs a big cleanup and merging with the other SDP and RTSP code.

Mmm,. lets keep this open and seperate from #568 (closed)

What is the problem now in this ticket ?

The problem is that the rtp access_output module doesn't support the specifying of muxers. It uses rtp muxing by default. Specifying mux=ts is thus invalid syntax. The only way to do MPEG2-TS muxing on a VOD stream is using the VLM instead.

The SDP is not broken because the access_output_rtp doesn't support specifying other muxers.
