Re: [Ccrtp-devel] Problem looking lost packets

[Mario Mateos]

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
