Colors shifted and only browsers recognize the device

[wilsoft-gt]

I have some issues, the first one is that only browsers recognize as a camera device, If I try Zoom, Skype or any other program it does not work. The second one is that on broser the color looks shifted:

I created the device with: sudo modprobe v4l2loopback video_nr=10 card_label="OBS Video Source" exclusive_caps=1

I have an nvidia GTX1060 with driver 450.80.02 and ubuntu 20.04.1, is there any way to make it work with nv12 codec?

I don't know if this will help but I had an issue with my colors being shifted. I'm using arch linux. Originally I installed v4l2loopback-dkms which only allowed me to broadcast in YUV420 and all the other formats would error out. I tried installing v4l2loopback-dkms-git from the AUR and then sudo modprobe -r v4l2loopback to make sure the old /dev/video2 on my system was removed then re-enabled it with sudo modprobe v4l2loopback to create a new one. After that I was able to use the YUY2 video format and my colors were showing correctly.

@thornycrackers Thanks bro, reinstalling v4l2loopback as you suggested came with support for the other formats.

Switching to YUY2 fixed color glitch for me.

If it happens again, you can also try using the resolution of 704x396; its what fixed it for me :smile:

Solved here in KDE Neon 5.20 (Ubuntu 20.04) removing libv4l2rds0 package. After this, the YUY2 video mode works and the image colors stay ok.

Can be solved everywhere by moving to new version of OBS Studio (26), which comes with v4l2loopback support without the need for additional plugins like this one.
