Comment # 1 on bug 1233674 from Christophe Marin

after a quick test, there are different issues

1/ the app doesn't know where Qt plugins path are by default.
I had to manually specify /usr/lib64/qt6/plugins/avkys in the plugins section
to have something listed on the second tab

2/ without the step above, nothing can be selected in the 'General options'
section

3/ even when steps above are resolved, the app still doesn't capture anything.
Tested with different 'video capture' settings and v4l2 camera driver.

'akvcam' seems to be the default settings, but that seems to require something
