OBS-studio 27.0.1-2 no longer showing virtual camera after update to 21.1 and kernel 5.14.x

[av8r]

First let my start by saying that obs and virtual camera (webcam) was working as expected before I updated.

I have completely uninstalled obs-studio and v4l2loopback-kdms including any .config and *rc files.
then reinstalled it.

but it’s still not working. I do not see the “Start virtual camera” button anymore.
When I go to add my webcam under the video capture device (v4l2) it sees my Depstech webcam but does not show the video feed.

I can start the camera and video feed if I use qt v4l2 test utility, so Manjaro must see and recognize it

I reinstalled obs and v4l2loopback using pamac.

I found this tutorial on the forum here but it seems to be old, I have not tried it yet.
https://forum.manjaro.org/t/howto-install-an-obs-studio-virtual-camera/67317
the reason I have not tried it is, I’m not sure if I can delete the git clone directories when it’s done?

Does anybody have the same problem?

Please read this:

[HowTo] become a Manjaro power user when you're a wizard at Windows but a N00b at Manjaro / Linux

Difficulty: ☆☆☆☆☆ Remember when you installed your very first Windows, added bells and whistles and then couldn’t see the wood for the trees any more and had to re-install? Well, you’re in the same situation now: You’re a N00b again! Embrace it! I know right now you’re thinking:

Why is this so much more difficult than Windows?

Especially the Linux has multiple kernels section, then try an LTS kernel and hopefully the problem will go away “automagically”.

As you gave me a : did the issue go away?

Still don’t see the output from the camera. But I got the virtual camera button back by reinstalling obs from pamac. But I loved that tread you liked to that will be my new reading material for a while. Henson the heart. I’m gonna open a new tread and find out what “webcams” people are using.

Thank you very much for your help:)

My solution was to:

pacman remove --no-save obs-studio 
pacman remove --no-save v4l2loopback-dkms 
sudo updatedb 
locate obs-studio 

Then use the rm --recursive --force --verbose command to remove all files leftover from OBS-studio.

Then reinstall OBS-studio, v4l2loopback-dkms, obs-v4l2sink, using pamac:

sudo pamac install obs-studio

(when prompted install v4l2loopback-dkms as well.)

sudo pamac install obs-v4l2sink

reboot your system and open obs-studio you should now have a new menu option under the Tools section called v4l2sink.

You might have to use this command:

sudo modprobe v4l2loopback

to get the start virtual camera button to show.
