This was not correct, both issues are present also in the latest version.
I've attached a patch which: 1. Adds a new member function scheduleReset() to ProxyRTSPClient This function is used to ensure the reset (including reconnection to 'back-end') is not done from within call stack of SocketDescriptor::tcpReadHandler. 2. Overrides RTSPClient::connectToServer in ProxyRTSPClient The overriding version will reset the ProxyRTSPClient if DESCRIBE has previously been sent. The purpose is to prevent a client to the Proxy from doing PLAY while reconnection to the 'back-end' is in progress. If this is allowed, RTSPClient::connectionHandler is replaced by SocketDescriptor::tcpReadHandler before the connectionHandler is called, meaning the RTSPClient is not functional. /Erik
