Your stream’s bitrate is exceeding the capacity of your network. You will lose RTP packets, ***even if you are streaming RTP-over-TCP***. (If you are streaming RTP-over-TCP, then eventually the TCP socket, inside the sender’s OS, will run out of buffer space, and several writes to the TCP socket - by the RTSP server - will fail. This is what you are seeing.) You CANNOT avoid data loss if your stream’s bitrate exceeds the capacity of your network (which is usually a lot lower than the nominal ‘speed’ of your network interface). This is physically impossible. The ONLY solution is to reduce your stream’s bitrate.
