This will allow you to do what you want to do (in your “RTSPServer” subclass).  (I’ll send an email to this list when this is done; stay tuned…)

I have now installed a new version (2021.01.14) of the “LIVE555 Streaming Media” code that makes the “lookupServerMediaSession()” function asynchronous.  (This function now includes parameters “completionFunc” and “completionClientData”, see “liveMedia/include/GenericMediaServer.hh”.)

If you want to reimplement this virtual function (e.g., a subclass of “RTSPServer”), you can do so as follows:
	Once you done the lookup, to get a “ServerMediaSession*” pointer (e.g., named “sms”), which might be NULL (if the lookup failed):
		if (completionFunc != NULL) {
			(*completionFunc)(completionClientData, sms);
		}
