Add support for front camera

[maplemedley]

Currently only the back camera can be used to record videos, would it be possible to add support for the front camera as well? For me it's much more convenient to use that.

Sounds good, I'll build it eventually. Feel free to open a PR if you know how

Thanks for considering it!
Sadly I have no clue and little time rn, so I can't help out that much atm. But I can help test out test builds or tweak existing code

Yes please front cam support would be greatly appreciated.
