You *cannot* call any LIVE555 library function (except "TaskScheduler::triggerEvent()") from a non-event-loop thread. I have explained this in the FAQ, and on this mailing list far many more times than I can count!</div><div><br></div><div>You can call "addServerMediaSession()" - from the event loop thread - at any time, but if you do this after you've already called "doEventLoop()" - i..e., while you're running in the event loop - then (obviously) you must do this from an event handler. So, you'll need to set up an event handler function that calls "addServerMediaSession()", and set up an event that gets handled by this event handler.</div><div><br></div><div>The best way to do this from a separate thread is to first (in the LIVE555 thread) create an event trigger using "TashScheduler::createEventTrigger()", and then (in the separate thread) call "TaskScheduler::triggerEvent()". For details, see "UsageEnvironment/include/UsageEnvironment.hh", and also the example in "liveMedia/DeviceSource.cpp".</div><br><br><div apple-content-edited="true">
