SUMMARY
***

***


STEPS TO REPRODUCE
1. Connect a camera (In my case i was trying a ps eye)
2. Use the camera (ie: ffplay /dev/video0)

OBSERVED RESULT
The camera is not listed on the camera indicator and remains in "No camera is in use" even when there's actual output from the camera (tested on ffplay, v4l2 and zoom)

EXPECTED RESULT
The camera indicator should show that a camera is in use.

It detects apps using it via PipeWire. It can't detect camera use for apps that open it in a lower-level way at the moment. Making this bug a wishlist requesting that it do so.

Oh, didn't know that, my camera has a led that turns on when in use so it's not really bothering me but some laptops don't, and having a way to tell if the camera is recording seems like a good idea. gj with kde6 btw runs great kudos to all the team.
