Below is a patch which corrects the arrival time calculation in the
recordReception function in incqueue.cpp.
The tarrival is in microseconds and the getCurrentRTPClockRate() returns a
timestamp in units per second.
The result of this patch is an correct jitter value in the RR and SR
reports.
please give comments about the patch.
Regards,
Rini van Zetten
