Hi,
I am trying to retrieve jitter, delay and packet loss values from the
received RTCP packets by redefining the onGotSR and onGotRR as below.
But the values I am receiving seen incorrect (they are very large). Is there
a bug in the library for what I am trying to do?
Is there a patch out there? Is there a mistake in my program?
Program -
// redefined from QueueRTCPManager
void
onGotSR(SyncSource& source, SendReport& SR, uint8 blocks)
{
RTPSession::onGotSR(source,SR,blocks);
RTCPReceiverInfo RecInf(&(SR.blocks[0].rinfo));
cout << dec
<< "Source IP:Port: " << source.getNetworkAddress() << ":"
<< source.getControlTransportPort() << endl
<< "Packet type: Sender Report" << endl
<< "Delay: " << dec << SR.blocks[0].rinfo.dlsr << " : "
<< dec << RecInf.getDelayLastSR() << endl
<< "Jitter: " << dec << SR.blocks[0].rinfo.jitter << " : "
<< dec << RecInf.getJitter() << endl
<< "Fraction Lost: " << dec << SR.blocks[0].rinfo.fractionLost
<< " : "
<< dec << RecInf.getFractionLost() << endl
<< "Cumulative Packet Lost: " << dec <<
RecInf.getCumulativePacketLost()
<< endl << endl;
}
// redefined from QueueRTCPManager
void
onGotRR(SyncSource& source, RecvReport& RR, uint8 blocks)
{
RTPSession::onGotRR(source,RR,blocks);
RTCPReceiverInfo RecInf(&(RR.blocks[0].rinfo));
cout << dec
<< "Source IP:Port: " << source.getNetworkAddress() << ":"
<< source.getControlTransportPort() << endl
<< "Packet type: Receiver Report" << endl
<< "Delay: " << dec << RR.blocks[0].rinfo.dlsr << " : "
<< dec << RecInf.getDelayLastSR() << endl
<< "Jitter: " << dec << RR.blocks[0].rinfo.jitter << " : "
<< dec << RecInf.getJitter() << endl
<< "Fraction Lost: " << dec << RR.blocks[0].rinfo.fractionLost
<< " : "
<< dec << RecInf.getFractionLost() << endl
<< "Cumulative Packet Lost: " << dec <<
RecInf.getCumulativePacketLost()
<< endl << endl;
}

Anyone has any ideas?
Thank you in advance.
