Hi all,

but v4l2sink doesn't appear in OBS > tools. I've found this information in github about it, but I still have the issue: https://github.com/CatxFish/obs-v4l2sink/issues/54

1642878083698.png


The directory /usr/lib/x86_64-linux-gnu/obs-plugins contains the file v4l2sink.so, but the OBS' Log show that v4l2sink.so is not loaded. Any idea what can I do? Here the OBS Log:

I forgot to say before running OBS, I run this command: "sudo modprobe v4l2loopback devices=2 card_label="OBS Cam" exclusive_caps=1"

And the OBS Devices are shown

$ v4l2-ctl --list-devices
OBS Cam (platform:v4l2loopback-000):
/dev/video6

Dummy video device (0x0001) (platform:v4l2loopback-001):
/dev/video7

PM-876 HD Camera: PM-876 (usb-0000:00:14.0-4.1.4):
/dev/video4
/dev/video5

Integrated IR Camera: Integrate (usb-0000:00:14.0-5):
