Can't capture from Logitech webcam on Ubuntu server
I am running an Ubuntu server 22.04 VM on an esxi host. I have connected my logitech webcam and passed it through to the VM. I have tried multiple programs to capture an image or audio from it but none of them work. The webcam seems to be correctly recognized from the system:

Basically nothing works, and I dont know what this "Inappropriate ioctl for device" error means which some programs output. Searching online couldn't find any helpful information.. Any ideas? |
