You're right - there isn't, unfortunately.  This information isn't 
exposed to the "RTSPServer" code, because it's not needed there. 
Instead, it's used by the "ServerMediaS(ubs)ession" object for the 
stream, via the 'streamToken' pointer (which the "RTSPServer" code 
treats as opaque).

Here's what I would do.  Unfortunately it requires first moving the 
definition of "class StreamState" from 
"OnDemandServerMediaSubsession.cpp" to 
"include/OnDemandServerMediaSubsession.hh".  (I might make that 
change in a future release of the code.)

1/ Have your "OnDemandServerMediaSubsession" subclass export a function
	FramedSource* framedSource(void* streamToken) {
		StreamState* streamState = (StreamState*)streamToken;
		return streamState->mediaSource();
	}

2/ In your "RTSPServer" subclass, for each RTSPClientSession* clientSession :
	for (unsigned i = 0; i < fNumStreamStates; ++i) {
		YourOnDemandServerMediaSubsession* subsession
			= (YourOnDemandServerMediaSubsession*) 
(fStreamStates[i].subsession);
		FramedSource* source = 
subsession->framedSource(fStreamStates[i].streamToken);
	}
