Mal by si doinštalovať v4l2ucp /universal control panel/  a popozerať sa, či netreba niečo prestaviť.  V4linux má niekedy konflikt s použitím /dev/video0 a potrebuje prestaviť na dev/video1 a pod.

A pod rootem cheese funguje (https://forum.manjaro.org/t/webcam-not-working-with-cheese-unless-sudo-ed/44724/8) ?

Taky viz https://bugzilla.gnome.org/show_bug.cgi?id=795022  =>

Right now it can be worked around by stopping pipewire socket before running cheese, like this:
`systemctl --user stop pipewire.socket'
but, if I understand correct, it breaks cheese to pipewire integration

After that cheese starts working fine, camera is found on every launching without issues.

Díky, zkouším...

Cheese nepotřebuji, ale kameru nenajde ani Skype, to je blbý... Najde ji naprosto spolehlivě VLC a guvcview a ukazuje krásný obraz (mě) :-)
