[Live-devel] Pausing an rtsp stream with TCP

[Ross Finlayson]

>I have a question about 'Pausing' a rtsp stream with TCP.

Can you explain this a bit more?  Are you referring to (i) 
implementing the RTSP "PAUSE" command in a RTSP client; (ii) 
implementing the RTSP "PAUSE" command in a RTSP server, if the RTP 
stream is being sent via UDP (the normal case); or (iii) implementing 
the RTSP "PAUSE" command in a RTSP server, if the RTP stream is being 
sent via TCP (i.e., over the RTSP TCP connection)?

If you're talking about (i), then the "RTSPClient" class already has 
a "pauseMediaSession()" operation.

If you're talking about (ii), then the RTSP server implementation 
already implements "PAUSE" on unicast streams (using 
"OnDemandServerMediaSubsession").  However, to use this, your input 
source class (a subclass of "FramedSource") will need to implement 
the virtual function "doStopGettingFrames()".

If you're talking about (iii), then it currently can't be done.  (For 
RTP-over-TCP, once the "RTPSource" object starts reading from the TCP 
connection, the TCP connection can then no longer be used for RTSP commands.)
