huwai p30 out of focus camera bug #204

Closed pcgrozema closed 2 years ago

pcgrozema commented 3 years ago

I want to make a PWA QR reader with ionic / angular. Your example does not work on all mobiles. I have a problem with the huwai P30. I see the camera as if it had some zoom and it does not focus well when I bring it closer to the qr or another object and therefore it does not scan the qr code. The mobile camera works well and takes pictures correctly. In fact, if I use other qr apps from playstore with (for example qrdroid) the camera works fine. Why does it blur on the PWA? That could be happening?

Thanks

This library is a QR code scanner, and has no logic for camera access.

It sounds like this is an issue with webcams - If you can confirm this is an issue with jsQR - aka not related to the webcam access, but rather to the call of this library, then feel free to clarify in the issue, however if you're just having trouble getting getUserMedia to work I'm unfortunately not going to be able to help much.

Closing this issue until it's clear it's an issue with jsQR not the webcam capture. Please comment/re-open if you feel this is in error.
