Summary of the bug: $title
How to reproduce:

# in one terminal:

$ vlc sintel.mpg
":sout=#transcode{vcodec=h264,vb=300,scale=0.25,acodec=mp4a,ab=128,channels=2,samplerate=22050}:rtp{mux=ts,sdp=rtsp://:8554/test.sdp}"

Of course, I'm not sure if it's a VLC or ffmpeg bug, but at least it's reproducible.

[cehoyos]

Is MPlayer (or any other application) able to receive the stream?

[rogerdpack]

unfortunately mplayer responds with

rtsp_session: unsupported RTSP server. Server type is 'VLC/2.0.4'.

then rejects it. odd.

[cehoyos]

Is that with or without live555 support in MPlayer?

[rogerdpack]

ok, with live555 it seems to sometimes work...after a long pause/delay it started playing it at least once, other times it doesn't work ​https://gist.github.com/4128685.

[codywohlers]

the same stream works on the same client using VLC, totem, and gst-play-1.0

[tpol]

It looks like FFmpeg incorrectly parses the SDP information in case of MPEG-2 transport stream.

When payload type is 33, it uses the Session control url instead of the Media control url in RTSP SETUP request.

I was able to receive the stream with the following fix:
