[Live-devel] Query regarding- detection of client disconnection from RTSP server

This will happen automatically (assuming that you used a non-zero value (e.g., the default value of 65) for the “reclamationTestSeconds” parameter in “RTSPServer::createNew()”).

If the server sees no activity (RTSP commands or RTCP “RR” packets) from the client in “reclamationTestSeconds” seconds, it will automatically stop streaming to that client.

When the *final* client goes away, then (assuming that you set “reuseFirstSource” to “True” in your “ OnDemandServerMediaSubsession” subclass’s constructor, when it called the “OnDemandServerMediaSubsession” constructor) the server will automatically close the input source - i.e., it will automatically call “Medium::close()” - and thus the destructor of - whatever ‘input source’ object you created in your implementation of the “createNewStreamSource()” virtual function.

I.e., if you defined your own “FramedSource” subclass for your ‘input data source’, and create an object of this subclass in your implementation of the “createNewStreamSource()” virtual function, the you should make sure that this subclass's destructor shuts down the input data source.
