[Live-devel] Proxyserver Subsession Teardown

[Lakshmi Narayan.G]

Hi Ross,
    Thank you for the reply. Yes It is PAUSE That is sent to the camera. 
(mistake in subject). The scenario in which I am facing the issue, is as 
follows

  * REGISTER a camera with Video and Audio subsession.
  * Client 1 - openRTSP -v rtsp://ip:port/streamid (VIDEO ONLY CLIENT)
  * Client 2 - openRTSP rtsp://ip:port/streamid
  * Stop Client 2

(Live.2016.02.22 unchanged code for Proxy and Client. Used 
testOnDemandRTSPServer for camera with test.264 and test.mp3 as subsessions)

Observation: With client 2 Exiting, ProxyServer will cleanup the 
resources allocated to the client, calls reclaimStreamStates() and in 
this process does closeStreamSource if no longer in use.

as I checked - this was found to be a rough flow of code that sends 
Pause to camera
/
/
/RTSPServer::RTSPClientSession::~RTSPClientSession()//
//reclaimStreamStates()//
//subsession->deleteStream()//
//~StreamState()//
//reclaim()//
//ProxyServerMediaSubsession::closeStreamSource//
//proxyRTSPClient->sendPauseCommand()/

This was verified for both UDP and RTP-over-TCP (Targeted usage will be 
RTP-over-TCP)
Could we send PAUSE only to that particular subsession and handle the 
same at the Camera side. Or any alternative way of handling this situation

When there are two (or more) ‘front-end’ clients streaming the same stream from the proxy server, then the closure of any one of the ‘front-end’ streams has no effect on what the proxy server does.  It’s only when the *last* ‘front-end’ stream closes that the proxy server will send a “PAUSE” command to the ‘back-end’ server.
