Re: [Ccrtp-devel] A newbie question about receiver report

[Federico Montesino Pouzols]

Hi, after a quick look at the code, I think the problem is your main
loop exits when there are no packets in the reception queue. Suppose
your program starts and no packet has been receive before:

>         while(socket->isWaiting()) {
>              receive(socket);
>         }

And suppose a number of packets are available, but after processing
them the queue becomes empty. I would try an infinite loop like
"for(;;)".
