Hello all,
I'm developping a streaming engine which should stream Layered Video (such as 
MPEG4-FGS bitstreams for example) and adapt the bitrate that is going out 
whenever feedback is received from the network.
I planned to use the ccRTP stack to do this, but I don't exactly see how the 
concept of RTPClockRate works:

How does RTPClockRate relate to the sending rate and to the timestamps I have 
to put when I enqueue an outgoing packet?
Do I have to adjust the clockRate on-the-fly as I adjust the streaming rate?
Moreover, is there a minimal inter-packet delay between 2 outoing packets that 
should be observed on this stack? How many packets per second can it handle? I 
guess it depends on the packet size?

Thanks for any input,
