Hi,
I have a setup of two RPi 4B 4GB (ground and air) equipped with ASUS AC56 wifi adapters. AirPi is also equipped with RPi V2 CSI camera. Currently I am using openHD 2.0.8.
Video parameters:
WIDTH=1280
HEIGHT=720
FPS=59.9
With any combination of the openhd parameters, I cannot get screen-screen latency below 150 ms, but as far as I see a lot of people claim that they reach values close to 100 ms with older versions of RPi.
Can you give me any advice or send your configuration file for RPi4 which can reach lower latency?
Alexey
