Very poor results on iPhone #786

Open yarekc opened 1 year ago

yarekc commented 1 year ago

Library works great on android /Google phone

But when I run it on iPhone 12pro, ba code détection is very difficult: it takes seconds to be able to read a bar code

I have noticed that increasing FPS to 100 gives better results, but still very far from Android

I tried to play with config, but was unable to get a decent result. Do you have any config suggestion so it works correctly on IOS ?

Regards

I really don't understand why people insist to use a bar code reader like a 3D game. I use everyday on IOS, windows, android, mac OS and Linux html5-qrcode for my development at 8fps and works great. your issue is probably a focus problem....

QRcode seems ok. But bar code reader does not: I need to stay motionless without breathing for 2-3 secondes to get a result (Iphone12)

On Android works great: great reactivity. So my question is : what config to use on Ios to get better result (raising FPS did help, but still not good enough)

Добрый день! Похожая проблема на Айфонах , причем на всех, даже на последних моделях https://disk.yandex.ru/i/e5E1bzniphb6iQ .

Разработчик каким-то образом работает над этой проблемой?

I have the same issue. Has anybody figured this out?

In my case, it didn't work on the iPad. But increasing the FPS to 100 and making the qrbox rectangular solved the issue. @yarekc thanks for the FPS tip
