[Live-devel] sigsegv when closing RTSPServer whilst streaming

[Piers Hawksley - Panogenics]

Thanks Ross,

The stack trace is below.

This crash occurs when closing the application whilst it is streaming. 
It does not occur when closing the application if streaming is stopped 
first.

It only occurs when streaming RTP over TCP; it doesn't occur when 
streaming RTP over UDP.

Please let me know if you need further debug.

Best Regards,

Piers
