[Live-devel] RTSP Server Crash with Milestone Client

[Viswanatha Reddy]

Dear Ross,
Thanks for your reply.
I collected the debug information while running with Milestone client and VLC client.
The snapshot of the crash pointing the crash inside the Server is also given.
Please find the attachment, which contains all the debug info.

Thank you,

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.
