We have logs for the stream IDs for which incomplete packet reads are made and they have odd numbers which mean they are RTCP packets. Here are some example logs for 2 streams from the camera: RECEIVED PACKET SIZE 52 FOR STREAM ID 1 ON SOCKET 22 BYTES READ = 52 RECEIVED PACKET SIZE 52 FOR STREAM ID 3 ON SOCKET 22 BYTES READ = 0 RTCP.CPP:358 : TCP socket #22, channel id 3 : packetReadWasIncomplete BYTES READ=0 for every alternately received RTCP packet.
