[Live-devel] segfault RtspClient

[Ross Finlayson]

Thanks for reporting this.  This is strange.  The problem appears to be occurring in the “SocketDescriptor” destructor; it is apparently finding - within its “fSubChannelHashTable” - a pointer to a “RTPInterface” object that had already been deleted.

But what I can’t (yet) understand is how this can be happening - because the “RTPInterface” destructor would have called “stopNetworkReading()”, which would have called “deregisterSocket()” for each of the (socket-number, stream-channel-id) pairs.  This should have removed the “RTPInterface”s pointer from each “SocketDescriptor”s “fSubChannelHashTable”.

Lots of people have been using RTP/RTCP-over-TCP streaming (for many years), and several bugs in this part of the code were fixed a few years ago - so it’s a bit surprising that nobody else has reported this new problem.  It appears that you are using the code in a way that many other people aren’t.  If you can figure out more about how/why this problem is occurring, please let us know.

Thanks again for the report.
