Our software, in accordance with the RTP/RTCP standard, delivers - to 
each client - data frames with an accurate presentation time.  These 
presentation times are times in the *sender's* clock.

If the receiver's clock runs at a different rate than the sender's 
clock (the clock used by the data presentation times), then the 
receiving application may need to compensate for this.  The mechanism 
that the application uses t odo so is (necessarily) application and 
codec-specific, and best handled by media decoders (which are not 
part of our software); therefore it is not something that we do in 
our libraries.

(For example, the receiving application might choose to drop some 
decoded audio samples, or to duplicate some decoded audio samples, as 
appropriate.)
