Comment 4 for bug 1923434

I have forwarded your bug upstream to https://bugreports.qt.io/browse/QTBUG-92597. Let's see what the upstream developers say about it.

If you want, you can register on that site and follow it, maybe they will want some more information from you.

For me the webcam works fine with 5.15.3 and Falkon (I tested on https://webrtc.github.io/samples/src/content/devices/input-output/), so maybe it's an issue specific to v4l1compat.so or something else.
