No, it's extracted from the stream itself - in the function 
"MPEG1or2AudioStreamFramer::currentFramePlayTime()".  (The bit rate 
estimation in the test program affects only the rate at which RTCP packets 
are sent; it is not important.)

Do you have an example of a file that illustrates this problem?  If so, 
please put it online and send the URL, so I can test it for myself.  (Try 
to find a file that makes the A/V drift most obvious.)
