tried a few more things but still no luck with the c920
A logitech c270 worked straight away. So I tried another c920 - didn’t work - eliminates the problem being a specific c920 fault
Installed the logitech capture/config software in case this installed some other driver. The capture software worked fine but connect VST still couldn’t see the video.
So that’s two different and clean windows 64 installations - 2 different c920 cameras. Neither worked. Tried VST connect version 3 - still nothing with the c920
Wonder what’s different about the c920 ? H264 ?
From memory I think the c920 took way less CPU, certainly under windows 7, as the h264 encoding is on the webcam and not on the CPU. It would be good to get this working
