Mjpg-Streamer on Rpi0

Hi MichaIng - thanks so much for your patience and help with this.

After a daemon-reload, I’m getting another error:

Now one would need to find the correct /dev/video* device node. /dev/video0 is obviously not correct. But probably it works with none of them this way (getting MJPEG stream from one of the devices), but they may all require libcamera: https://www.raspberrypi.com/documentation/computers/camera_software.html#device-nodes-when-using-libcamera

I have a camera module 3 now as well, and will tinker with this when I find time.
