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);
                }
