[Live-devel] Implementing SET_PARAMETER and GET_PARAMETER

It depends on which object's state you want to update as a result of 
the "SET_PARAMETER" operation.

If you want to update the state of the "RTSPClientSession" object, 
then yes, you'd probably need to add a virtual function to 
"RTSPClientSession".

If, however, you want to update the state of the "RTSPServer" object 
only, then you could probably do this by writing a generic 
implementation of "SET_PARAMETER" for "RTSPClientSession" that calls 
a new virtual function in "fOurServer" ("RTSPServer").

And if you want to update the state of the "ServerMediaSubsession" 
object, then you would have even more work to do.
