I'm using the live555ProxyServer to be able to reliably record and view streams from four cheap cameras concurrently. Recording is done in 15 minute chunks with 15 seconds of overlap, meaning there will normally be between 4-8 active clients for the 4 proxied streams. The live 555 version is 2015.12.22, compiled for linux-64bit.
Today the live555ProxyServer got stuck in an endless loop, with this tail of the log: ProxyRTSPClient["rtsp://192.168.0.126/ch0_0.h264/"]::continueAfterSETUP(): head codec: H264; numSubsessions 2 queue: H264 MPEG4-GENERIC MPEG4-GENERIC "MPEG4-GENERIC" is then endlessly repeated. I guess the 2nd element in the list starting with fSetupQueueHead has ended up linking back to itself somehow? I think the setup should mean the camera at 192.168.0.126 has just rebooted or reconnected to the network, normally the only event being logged is transmission of "OPTIONS". (That's used to keep the connection alive?) Any suggestions for debuggin this would be really welcome! Some more log if useful: Received 155 new bytes of response data.
