Yes, you can use the RTCP-provided "jitter" statistic for this 
purpose.  Note the "RTPReceptionStats" class.  To access this class, 
see, for example, how "openRTSP" implements the "-Q" option.

To be honest, I'm not sure how you would use the "jitter" statistic 
to calculate an estimate of the client's buffer size, but there's 
probably information out there on the Internet about this...
