Camera example not working: The camera service is missing

Johan Borkhuis

Hello,

I am trying to run the Camera example on my embedded system (i.MX8 system), but when started I get a warning-popup telling me that the camera service is missing, and also the list of devices is empty.

I know the camera is working, as I can get an image from it using gstreamer, but for some reason the streaming is not working.

What service is missing, and how can I start this service, or how can I debug why the service is not started?

My system:

i.MX8 based
Qt 5.15.7, using eglfs
Yocto based, linux kernel 5.15.71

My camera-data

# v4l2-ctl -all -d /dev/video0
