Irgendeine Idee, was ich tun kann?

Antwort1

Ich habe es gelöst. Deaktivieren Sie Secure Boot. Ich habe v4l2loopback neu installiert.

sudo apt install v4l2loopback-utils v4l2loopback-dkms cmake nasm yasm pkg-config libgtk2.0-dev
sudo modprobe v4l2loopback
v4l2-ctl --list-devices     # check if you have dummy video devices
Dummy video device (0x0000) (platform:v4l2loopback-000):
/dev/video0
