I suggest subclassing each "RTPSink" class that you use, and redefine 
the "auxSDPLine()" virtual function to add the following SDP line:

a=framerate<fps>\r\n

where <fps> is the frame rate (in frames-per-second).  If you do 
this, then the client will automatically parse this line, and make it 
available to clients via the "MediaSession:: videoFPS()" function.

Of course, this begs the question of how you (the server programmer) 
gets this frame rate from the input data - but that's for you to 
figure out.
