But I think that the information I need is the one which comes from the
receiver to the sender because is the Receiver who loses the packets, and
the SR Reports comes from Sender to Receiver. Besides, how can i see the
information of SR Reports? I've tried to do it redefining the functions
OnGotSR() this way:
void onGotSR(SyncSource& source, SendReport& SR, uint8 blocks)
{
RTPSession::onGotSR(source,SR,blocks);
cout << "I got an SR RTCP report from "
<< hex << (int)source.getID() << "@"
<< dec
<< source.getNetworkAddress() << ":"
<< source.getControlTransportPort() << endl;
RTCPSenderInfo SenInf(&(SR.sinfo));
cout << "RTPTimestamp: " << dec << SenInf.getRTPTimestamp() <<endl;
cout << "RTPTimestamp: " << dec << SR.sinfo.RTPTimestamp <<endl;
cout << "Paquetes enviados: " << dec << SR.sinfo.packetCount <<endl;
cout<<"Paquetes enviados: " << dec << SenInf.getPacketCount() << endl;
printf ("Fraction lost: %u\n",
SR.blocks[0].rinfo.fractionLost);
}
But using a RTCPSenderInfo object it doesn't work (the value is the same in
any packet), and accesing directly to the value, i think it's not correct
(The two values are different). What am i doing wrong? How can I see the RR
information after receiving a SR packet? I think I'm lost with it.
Thanks for replies

If you receive SR packets, you have all the information you need. SR
packets include RR-like reports as well as additional (sending)
information.
