OBS studio as green screen for Jitsi

Dear all,

I have found some videos about installing OBS Studio for LInux and using it as virtual webcam for Jitsi, so I could use a green screen instead of the blur effect.

Now, I have installed the packages, I can start OBS Studio, I have set up everything as shown in the videos on Youtube. I just can't get the virtual webcam to work. The system shows me:

/dev/video0
/dev/video1

Both are the webcam of the laptop. It seems that I can't geht the V4L2sink activated to set up a virtual webcam.

Can someone please help me? Perhaps you know another software which can do such a thing as green screen and hand it over to Jitsi?

Thank you very much in advance!

Cheers,
dexic

Re: OBS studio as green screen for Jitsi

To get the v4l2sink plugin to work in OBS, you need to make sure you have `v4l2loopback' installed, which I assume you do. You will also need to run the command `sudo modprobe v4l2loopback' to create a loopback device that v4l2sink can use.

Note: if you want to use it on google-chrome or chromium-based browsers, you need to do `sudo modprobe v4l2loopback exclusive_caps=1', instead.

Fun fact: I actually have no clue what I'm doing

Re: OBS studio as green screen for Jitsi

OK, I have installed the following packages:
obs-studio
v4l2loopback-dkms
obs-v4l2sink

I have tried the modprobe, but I always receive an error like:
modprobe: FATAL: Module v4l2loopback not found in directory /lib/modules/5.11.2-arch1-1

So, what am I doing wrong? :-)

Did you install linux-headers? DKMS packages require the headers of the kernel you are intending to use, if you have the headers but you've run an update in the meantime you'll want to reboot into the new kernel

Re: OBS studio as green screen for Jitsi

After installing linux-headers:

(3/3) Install DKMS modules
Unable to install module v4l2loopback/0.12.5 for kernel 5.11.5-arch1-1: Missing kernel modules tree.

So what's next?

Update your system, don't install single packages.
