[Live-devel] Information accessible in TransmissionStatsDB

Hi Ross,

I have some questions regarding data accessible in TransmissionStatsDB.
Can you please confirm the exact meaning of the return values of the
function and its units.


1) I think that both
lastSRTime()
diffSR_RRTime()
return the time in units of 1/65536 seconds. Is that right?


2) timeCreated():
I always receive a constant value. Is that the NTP time the session was
created?


3) lastTimeReceived()
Does it return the NTP time the last report was received (for
calculation of round trip delay)?


4) lastPacketNumReceived()
Is that the "extended highest sequence number received" as defined in
RFC3550?


Furthermore I have a question regaring the sending ofrtcp reports. It is
possible to send RTCP reports in a defined time interval through the
sendReport() function. But still the "normal" scheduled RTCP-Reports are
beeing send. Is it possible to disable the sending of these "normal"
RTCP reports?


Thank you very much for your help!

Martin
