[Live-devel] RTSP Server 'Keep Alive' support

[Ross Finlayson]

Yes.  Note the "reclamationTestSeconds" parameter (default value, 45 
seconds) in "RTSPServer::createNew()".

Yes it does.  The server treats either an incoming RTCP "RR" packet, 
or any RTSP command (not just "GET_PARAMETER") as indicating client 
liveness.

Note, though, that if you requested RTP-over-TCP streaming, then 
(because of software limitations) the server will not see any RTSP 
requests after "PLAY".  However, incoming RTCP "RR" packets will 
always be handled (and used to indicate client liveness).

All standards-clompliant RTSP/RTP clients should send RTCP "RR" packets.
