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...
🙂 yes, @Opolork : posts have specific topics, which makes them easy to find... so if someone has an issue, others who might have the same issue, or have had in the past, might be able to help, or get help.
