[touch] Can't record camera video to a file

[Michael Terry]

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).

And the same copy-paste about testing on Qt 5.5.1 in this bug :)

If 5.5.1 solves the problem, it is possible to consider trying out shipping Qt Multimedia 5.5 (only) on top of otherwise Qt 5.4.1 for stable image users. This should be possible unlike mixing some of the more core modules.

No change with 5.5.1-1ubuntu1~xenial1~test1 from the PPA on mako image 353 (devel-proposed).

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.
