First, the easiest way to do this is to run each RTSP client in a separate
*process* (i.e., in a separate application, *not* as a separate thread within a
single application). If you do not need to share memory between the stream
receivers, then this is the simplest solution.
The rest of this message, however, assumes that - for whatever reason - you
want all of your stream receivers to run in the same application (i.e.,
process).
How to start playing another stream? This depends - What decides when a new
stream should be played? Whatever this is, it will need to be handled as an
"event", within the event loop.
Perhaps, for example, you have a GUI - running in a different thread - where
the user indicates (perhaps by filling in a form and clicking a button) that a
new stream should be started. In this case, you could use the "EventTrigger"
mechanism that's defined for the "TaskScheduler" class: See
http://www.live555.com/liveMedia/faq.html#other-kinds-of-event
Or perhaps you have a TCP socket connected to a console that the user is using
to type commands (e.g. "start-playing <rtsp-url>"). In this case, this
'command-line user interface' TCP socket could be read and parsed from within
the event loop - using a handler that's set up using the
"TaskScheduler:turnOnBackgroundReadHandling()" routine.
But whatever you do, the 'event' that determines that a new stream needs to be
played is an 'event' that will need to be handled within the event loop.
