FYI, you could also use our "testRTSPClient" demo application for this. It can
stream from multiple "rtsp://" URLs concurrently.

That's strange. I suspect that the problem is (somehow) related to your 'data
source' implementation - i.e., your "FramedSource" subclass.
What happens when you don't just 'base' your server on
"testOnDemandRTSPServer", but actually use the (original, unmodified)
"testOnDemandRTSPServer" code? What happens when two clients request the same
stream (from a file)? And do things change at all when you change your server
to use a single input source for all concurrent clients - i.e., if you change
line 29 of "testOnDemandRTSPServer.cpp" to
Boolean reuseFirstSource = True;
?
