We are using live555 library (proxyServer) for proxying the back-end Camera streams to end clients in one of our applications.
Recently I was trying to write a Camera simulation application (using live555 2017.09.12) to test our Proxy Server. This Camera simulation app Registers an RTSP stream (generated from local video file) with our Proxy Server application. I have implemented this code referring to testOnDemandRTSPServer.cpp. This code is working fine.
But occassionally stream is not getting registered properly with the Proxy Server. With the help of tcpdump and additional logs, I have found that Camera simulation app received DESCRIBE request along with response to REGISTER request. Below is the corresponding log that printed contents of fResponseBuffer during Registration failure.
fResponseBuffer :
RTSP/1.0 200 OK
CSeq: 3
Date: Thu, Oct 12 2017 14:56:02 GMT
DESCRIBE rtsp://10.0.1.163:8554/matroskaFileTest RTSP/1.0
CSeq: 2
User-Agent: Video Framework
Accept: application/sdp
Because of this, DESCRIBE request is not processed by Camera simulation app and Registration is getting failed some times.
Steps to reproduce :
Register a stream (generated using sms object in testOnDemandRTSPServer.cpp) to proxy server using RTSPServer::registerStream(). Then run this binary (testOnDemandRTSPServer) in several times. Occassionally REGISTRATION would fail because of this issue. This can be confirmed by printing contents of fResponseBuffer in RTSPClient::handleResponseBytes().
