I am developing a python application where a drone and a computer communicate over local network (wifi). My need is to stream the drone's camera to OpenCV-python on the computer with the lowest possible latency at the highest possible resolution.

Thus far I have been trying rather naive approaches over TCP that give okay-ish results, I get something like 0.1s or 0.2s latency for VGA format. It has a point for some use cases as it enables lossless transmission, but since the most common scenario is to aggressively control the drone in real time from the stream, I am aiming for something of much lower latency and hopefully higher resolution.

My advisor has recommended using WebRTC. I have done some research on the matter, found the aiortc library that implements WebRTC in python, but I am unsure this is the way to go for my use case as it seems to be more geared toward web developers.

I am a bit lost I think. Could you highlight the advantages of WebRTC in my application if any, or point me toward solutions that are more relevant for my problem please?

Thanks in advance!

[1]Protocol comparison

rtc communicate peer to peer, I think you knew that. And if u use local network U will not need STUN server or TURN to connect two devices. That is make more decrease latency and code shorter. I'm not work with drone but I think your method stream had latency < 0,2 is good. fyi protocol campare
