Hello. I missing RTP frames, when connect with my H264 plugin on connection speed greater then approximately 256 kBps. I inserted logging of rtp frames sequencenumber in function RTP_Session::SendReceiveStatus RTP_UDP::ReadDataPDU(RTP_DataFrame & frame); after call SendReceiveStatus status = ReadDataOrControlPDU(*dataSocket, frame, TRUE); and periodicaly I have holes in sequence of numbers. At the same time I have working sniffer, and I see that RTP packet missing in my logs is present in sniffers statistics. I tryed to find the place in h323plus sources where can I miss RTP packets, but couldn't find it :( The missed group of packets (even if length of group is 1 - single packet) always ends with rtp packet which have marker=0 Help me to find out the reason why I missing packets. Because of speed?
