[Live-devel] Stopping an RTP stream safely/Deleting objects

[Emile Semmes]

Hi all,

I'm streaming an MPEG-2 TS file using code very similar to 
testMPEG2TransportStreamer.cpp. In one of my use cases, I need to stop 
the stream immediately instead of allowing it to complete. I'm doing 
this currently by passing a watch variable to the 
taskScheduler().doEventLoop() call and allowing another thread to set 
that variable when I need to stop playback.

My question is what do I need to do after that to safely stop and delete 
my related objects (UsageEnvironment, RTPSink, etc) if I leave the 
doEventLoop() early? I'm assuming calling Medium::close() on the object 
created by MPEG2TransportStreamFramer::createNew() is correct, but I'm 
not sure what I should call to destroy the object created by 
SimpleRTPSink::createNew(). The destructor is protected so delete is 
forbidden.
Also, should I make a call to RTPSink::stopPlaying() and if so, when? 
I'd like to reuse the RTPsink but give it different parameters on a 
subsequent use.

Thanks,
Emile
