Help in Setting up OBS Studio virtual output using the Snap versions

I’m trying to setup a virtual output using OBS for Zoom and Discord video calls.

When I went to Tools -> V4L2 Video Output, I got “format not support” on any video format:


I tried /dev/video1 since that was also there when I checked.

I saw in a [tutorial}( that I should install v4l2loopback-dkms, & followed it by typing sudo modprobe v4l2loopback video_nr=10 card_label="OBS Video Source" exclusive_caps=1 in the terminal. Didn’t work either.

FYI, I’m using an NVIDIA GeForce GTX 1060
