[Live-devel] Access violation in ReorderingpacketBuffer::freepacket

[Jeff Shanab]

Thanks. I have gotten it to crash 4 or 5 times now and in all cases the Packet is in varying states of destruction. The previous observation about max packet size was not repeatable.  This points to a race condition. The code is identical to all the other camera models but it is possible this is the first one calling into use packet-reordering.

There is something different, for sure. But I am connected to 25 to 400 cameera streams so crashing the whole process because of double delete or heap corruption is a real problem. I will let you know if I find anything profound.

Unfortunately you're probably going to track this down yourself, unless you can get the crash to happen with the "testRTSPClient" demo application.

However, you mentioned before that your crash happened after you introduced a "new brand of camera", so you might want to begin by investigating what might be different about this camera.  In particular, I suggest starting by comparing the SDP description returned by this camera with that returned by your other cameras (that don't cause the crash).

But apart from that, you're on your own.  Sorry.
