Yes, this is an optimization that our server code makes - based on the (usually
correct) assumption that the properties of the (same-named) stream will not
change.

You can do this by - in your “OnDemandServerMediaSubsession” subclass -
redefining the virtual function
virtual char const* sdpLines();
and reimplementing it as follows:
char const* yourOnDemandServerMediaSubsessionSubclass::sdpLines() {
delete[] fSDPLines; fSDPLines = NULL;
return OnDemandServerMediaSubsessionSubclass::sdpLines();
}
