Unable to unload v4l2loopback, Close any programs using virtual video devices and try again about mon2cam

[AkumuKernel]

Hi, hi, i have same problem, but, i tried to use sudo sudo
modprobe -r v4l2loopback
and:
modprobe: FATAL: Module v4l2loopback not found.
I have v4l2loopback installed
I'm on Linux archiso 5.6.10-arch1-1

It just means any error happened when trying to unload v4l2loopback, try sudo modprobe -r v4l2loopback and see if that works, if something like discord is using any webcam, even just having the settings page open on the video page uses the webcam.

I had recently done a system upgrade and forgot to reboot. A reboot fixed it. I'm sorry, I am an idiot. Thanks for the help though 😄

No problem, things like that are confusing with no real error

If you're getting Module v4l2loopback not found you have to install v4l2loopback

You also have your kernel headers installed and rebooted?

Yes I have the core/linux-headers arch package installed and rebooted many times
