I'm streaming audio/video from an IP camera through VLC as the client. I have
no documentation on the camera. I need to use rtsp to stream the audio and
video channels separately, but I can't seem to get it to work here. Also, from
the SDP message it appears to use Live555 v2009.09.28 as its rtsp server. On
other cameras I've been able to use something like rtsp://ip:port/control, but
it's not working for me here. Below is the sdp message:

Here's what I've tried:
rtsp://192.168.1.123/mpeg4 -- streams both a/v
rtsp://192.168.1.123/track1 -- error, your input can't be opened
rtsp://192.168.1.123/mpeg4/track1 -- error
rtsp//192.168.1.123/mpeg4#track1 -- streams both a/v
rtsp://192.168.1.123/foobar/mpeg4 -- streams both a/v
rtsp://192.168.1.123/mpeg4/foobar -- error
In the VLC toolbar, I can select Video-->VideoTrack-->Disable, to turn off the
video, but I need to be able to do this with the rtsp url. Not sure if there's
some finer point of the url syntax that I'm missing, but perusing the RFC's
hasn't really helped so far.
Thanks!
