THX for your fast answer.

Sorry, perhaps I didn't explain my complete scenario. I subclassed
ServerMediaSession in RTSPServerMediaSession and ServerMediaSubsession in
NMMServerMediaSubsession. The single input stream is replicated by NMM by a
mechanism called session sharing. This mechanism works very fine in our
environment (for example with a XDisplay or Playback).

I tried to implement the subsession in such a way that is similar to your
OnDemandServerMediaSubsession but there has been some problems (so much time
ahead so I can't remember why ;-)) so I subclassed ServerMediaSubsession. The
most significant difference is, that I have for each client a seperate liveMedia
part (source->framer->sink).

The NMM graph is built in der SMSession-Subclass. The SM-Subsession has the
control about the liveMedia-part such as the BufferedSource (is a FramedSource),
the Framer and the Sink. So in theory for the liveMedia part it should be no
difference if I have two file sources and two sinks or one source which is
replicated and two sinks.
