4 years ago Hit this same issue, I think there's just some information missing on how to use. Try this:
modprobe v4l2loopback video_nr=5 card_label=“Virtual_cam”
Then use /dev/video5 as plugin target
Worked for me
When trying to enable output I get format not supported on any option.
Really interested in getting this to work to avoid having to use corporate MS BS programs.
v4l2-ctl --list-formats ioctl: VIDIOC_ENUM_FMT
The above is all I see so I guess there is no video devices. My system has 2 /dev/video0 and 1 my webcam is on /dev/video1
