내가 뭘 할 수 있는지 알아?

답변1

나는 그것을 해결했다. 보안 부팅 비활성화 v4l2loopback을 다시 설치했습니다.

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
