First of all, use compositor (or glvideomixer) as provided by GStreamer
1.6 and newer. The old videomixer is not going to work well with live
streams like RTSP.

It would work exactly the same as an application with a single stream
to a videomixer. You would wait for the pad-added signal on rtspsrc,
from there get the pads with the RTP streams and link in a decodebin or
anything else that would decode your video. Then on the pad-added
signal of the decodebin you would request a sink pad from the
compositor element for each of the streams.

And the compositor itself would be linked further downstream to
whatever sink you want to use.


For details check the application developer's manual about the pad-
added signal and request pads. Section 8 of that document.
