Public bug reported:
I can't seem to get a Camera qml object to record to a file. I get the
error "Could not open file for video recording". I'm using the sample
code below [1] and get the output below [2].
I'm using the camera, microphone, and video apparmor profiles.
"/home/phablet/Videos/testing.testing/" did not exist. I tried making
that directory in case that was the problem, but it didn't help (and I
feel like QtMultimedia should make that if needed anyway).
