/dev/video99: No such file or directory #128

Open hannesbhm opened 2 years ago

hannesbhm commented 2 years ago

Hello! I get the following error:

pi@raspberrypi:~ $ cd /dev/video99 -bash: cd: /dev/video99: No such file or directory

Im sure that i did every step right and can open the cam via homekit but without pictures. The camera doesn't answer.

Maybe someone can help me. Thanks!

Looks like it works only on Buster OS right now. I've tried Bull Eye - it doesn't work.

Try installing that. i have made it run on Bull eye as well after some configurations and this was the key: sudo apt install linux-headers

Try modprobe v4l2loopback and see if the v4l2loopback module is available for the current kernel.

I had the same error due to the absence of headers for the active kernel updated by rpi-update. If you're in the same situation, try to revert kernel & header versions to stable ones:

sudo apt update
sudo apt install --reinstall raspberrypi-bootloader raspberrypi-kernel
