Hi again!
Now, I'm having trouble with statistics. I call the
SyncSourceLink::getCumulativeLostPackets()-method (iqueue.h). It seems,
however, that the baseSeqNum used in SyncSourceLink::computeStats()-method
always is zero.
I expected the method SyncSourceLink::initSequence to be called when the first
packet arrived. First, the method is never called when I run my tests (might be
because of my tests i guess), secondly I expected it to initiate the baseSeqNum
but it doesn't.
Now, I've added a line to IncomingDataQueue::recordReception to initiate the
baseSeqNum:
----------------------------------------
...
if ( result ) {
// the packet is considered valid.
srcLink.incObservedPacketCount();
srcLink.incObservedOctetCount(pkt.getPayloadSize());
srcLink.lastPacketTime = recvtime;
if ( srcLink.getObservedPacketCount() == 1 ) {
// ooops, it's the first packet from this source
setSender(*src,true);
srcLink.baseSeqNum = pkt.getSeqNum(); // Added by me
(Jörgen)
srcLink.setInitialDataTimestamp(pkt.getTimestamp());
}
...
-----------------------------------------
Now, at least the number of lost packets is not HUGE but still, the number of
lost packets is about twice the number of received packets. Might of course be
because of the client I use in these tests. To get the statistics I stream a
quicktime-file with JM Studio and I've not looked how it generate the sequence
numbers...
Anyone using the statistics from ccrtp?
