I am hoping that it may be a missing package that can be installed or possibly modifying the mjpeg-stramer command, however, I am not sure what I can do.

Hm this shows that your cam only supports GRBG and YUYV. Are you sure that you run it before with MJPG?

Thanks, @Jappe I am not sure what mode I ran mjpeg-streamer on this camera on the old install. I used to run this camera on an old pi3 too. I may need to fork out and get a new camera (with a long USB cable - the reason I am using this one is that it has a nice long USB cable that reaches my printer nicely).

If there is a way to switch mjpeg-streamer to run in GRBG or YUYV that would be an easy fix but I am not sure if that is something that can be done with mjpeg-streamer.

Alright I did a bit testing since I have a cam which supports MJPG and YUYV.
There is a -y flag to start mjpg-streamer in YUYV mode.
You have to edit the service file:

dietpi-services → mjpg-streamer → edit
Then nano opens the file, you have to edit [Service] section. Uncomment the #ExecStart= line and add the -y after the video device. Also add another ExecStart= like shown in the example:

ExecStart=
ExecStart=/opt/mjpg-streamer/mjpg_streamer -i 'input_uvc.so -d /dev/video0 -y' -o 'output_http.so -p 8082 -n'

Save the file and restart the service and check via journalctl if it now uses YUYV.

Thanks for following this up - I tried modifying the command to include -y to use the YUYV format but I had no joy.

I managed to get the camera working on motioneye which is a workable solution, although I expect that it is a little more resource intensive than mjpeg-streamer. So this solves my problem.
Thanks again for your assistance.
