[Live-devel] RTSP Server Crash with Milestone Client

Unfortunately, because the problem seems to happen only with your custom server, we can't reproduce it ourselves, so you're going to have to identify precisely where - in our code - your server is crashing, and why.

(BTW, almost everything within a LIVE555 application happens "inside the event loop", so that's probably not significant.)

For starters, I suggest turning on debugging printing in the "RTSPServer" code by adding

#define DEBUG 1

near the top of "liveMedia/RTSPServer.cpp", and recompiling.  This should help tell you what's going wrong.

It's conceivable that your new client has somehow (perhaps by using slightly different RTSP command syntax) uncovered an error in our server code - in which case I'd be very interested in discovering this.
