v4l2loopback "format not support" error in OBS Studio

Question

I keep getting a weird error in OBS Studio while trying to enable my virtual camera, "format not support". This is after installing packages in Manjaro 19.0.2:

yay -S dkms linux56-headers
yay -S obs-v4l2sink v4l2loopback-dkms

Is this a OBS issue or a v4l2loopback one?

I found it. I forgot to run sudo modprobe v4l2loopback. It enables it I think.

please accept your answer, so it doesn't show up as unresolved any longer. – umläute Sep 21 '20 at 15:19

Some stuff that help me figure out a similar issue:

Note that this issue can also arise from a video device that is not available e.g. /dev/video1 when there is no active device /dev/video1 changing to another device e.g. /dev/video0 may resolve this error

list devices with:

ls /dev | grep video

you may be able to make additional devices available when you load the kernel module:

sudo modprobe v4l2loopback devices=2
