First, note that the “ProxyServerMediaSession” implementation automatically reconnects to the ‘back-end’ RTSP server whenever its connection fails (and/or it detects that the stream is no longer alive).  So there is nothing that you should need to do yourself to recover from this.

If you want to see more information about what the “ProxyServerMediaSession” is doing to recover, then you could pass a value of 2 as the “verbosityLevel” parameter (equivalent to running “live555ProxyServer” with the “-V” option), to get enhanced error output (to ’stderr’).  If you want to do more than this, you could subclass (or, at worst, modify) “ProxyServerMediaSubsession”, but then you’re on your own.
