✨ Control preview resolution

[Emilien1982]

What feature or enhancement are you suggesting?

Hi.

I'm using RNCV to scan QRcodes.
At the moment, on Samsung S21, I can scan ~5 codes simultaneously at a ~50 cm distance.
I enabled the zoom, so I can scan longer distance but with a narrow field (meaning 1 or 2 codes).
I need to reach 20 codes at 2 m (so without zooming).

My thought is: if far codes are read when zooming, the app receive a hight resolution image and lower it on preview without zoom.
Lower preview resolution make sens for many cases but in my case it's not wanted. I would assume lower FPS with higher resolution.

Thanks for considering adding a preview resolution parameter.

What Platforms whould this feature/enhancement affect?

Android, iOS

Alternatives/Workarounds

I currently trick the distance with the zoom. But it reduce ne number of codes I can scan simultaneously.

Guten Tag, Hans here 🍻.

Thank you for your suggestion on controlling preview resolution! It sounds like an interesting enhancement for scanning QR codes more effectively. However, I would recommend providing more technical details about your current implementation, including any logs or errors you may have encountered. This would greatly assist mrousavy in understanding and possibly addressing the issue more efficiently.

If you have access to logs from the development environment, please gather them and include those in this issue. This would help us determine if this is a more fundamental problem with the library or just an implementation detail.

Looking forward to your updates!
