[Live-devel] Access violation crash in rtspclient

[Ross Finlayson]

I'll be doing something similar to your first fix (but it most certainly will not be using a "goto" :-)

OK, that's your fault.  You're using the synchronous "RTSPClient" interface - which is OK - but you're having your "BYE" handler callback routine delete your "RTSPClient" object while you're in the middle of a synchronous operation.  That's bad (on your part).  (It's weird that you're getting a RTCP "BYE" before you get a response to your RTSP "PLAY" command, but I suppose that's possible...)

What you'll need to do, then, is have your "BYE" handler routine set a Boolean flag (but not actually delete anything then), and have your code test for this flag after it returns from "playMediaSession()".
