[Live-devel] How to update SDPLines info?

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();
	}
