If you haven’t done so already, please read

It’s important to understand that LIVE555-based applications run with a single
thread of control, using an event loop - rather than threads - to provide
concurrency. Note, in particular, that the “testRTSPClient” demo application
*already* allows you to specify more than one “rtsp://“ URL on the command
line; each of these RTSP streams will be opened and received concurrently -
i.e., using a *single* event-loop thread. For example:
testRTSPClient rtsp://stream1 rtsp://stream2 rtsp://stream3
If, however, you *really* want to run multiple RTSP clients - each with its own
thread of control - then the best way to do this is to run each RTSP client in
its own *process*, not as multiple threads within a single process. For
example, you can run the “testRTSPClient” application (or your own RTSP client
application) multiple times, concurrently - for example:
testRTSPClient rtsp://stream1 &
testRTSPClient rtsp://stream2 &
testRTSPClient rtsp://stream3 &
