[Live-devel] Adding streams to already-running event loop

[Ross Finlayson]

> I’ve got this working along the lines you’ve described, but the problem I’m running into is a need for some kind of external (to live555 thread) reference to each RTSPClient, in order to trigger other events (stopping one, for example). That’s why I thought about creating the clients outside of the loop, but I can understand why that’s not a good idea. Creating the RTSPClient instance inside the eventTrigger handler doesn’t provide a way to pass a reference back, either (as far as I can tell).

I suggest creating - in the external thread - some object (struct) that represents the stream.  This struct could contain some fields (such as the RTSP URL) that would be set by the external thread, and other LIVE555-specific fields (such as a pointer to a “RTSPClient” object) that would be set and accessed only by the LIVE555-event-loop thread.

Then, pass a pointer to this struct (rather than just the RTSP URL) as the ‘clientData’ parameter to “triggerEvent()”.
