have it be an AppArmor confined app
Humm, that's not possible at the moment 🙂 .
The camera app is unconfined for a reason and it's the same limitation for the video chat feature.
Of course having a person fully dedicated to the one task of making camera experience better is a good idea.
But the contribution from Pine64 (10$/PP Ubports CE) is not enough to hire a good engineer for a year.
And, as I estimate, that will be roughly what is needed to focus on camera app only without the vast amount of work required for device specific issues with their camera...
