[Live-devel] memory leak in RTSPClient when SETUP is processed

And it gets delete[]d later, when the RTSPClient does a "TEARDOWN".  So this isn't really a memory leak.

However, I can see why "valgrind" might get confused by this.  The "sessionId" field in "MediaSubsession" is a bit strange, because it - unlike most class member fields - is not managed by the class's member functions and/or its constructor/destructor.  Instead, it is managed by whatever code happens to use the "sessionId" field - in this case, the "RTSPClient" code.  (Note that "MediaSession"s can be used without RTSP - e.g., if you want to receive a multicast stream using only its SDP description.  So "sessionId" is not an inherent property of a "MediaSession".)

However, because you're at least the third 'valgrinerd' :-) to have asked about this over the years, I might end up changing this behavior, so I don't keep getting questions about this...
