Hello Captain Björn,

is it possible, to get an newer version of the jsqr-component integrated? I ask, because the current version shows only a black area in browser on an iOS smartphone or pad?

I have searched hints for that in internet and found that this is fixed with a newer version of the component.

Regards,
Holger

Hi,

I just tesed with iPad and do not see any problem...???

Please note: you need to use https for accessing the camera, http is not enough. Could you check this?

Thanks! Björn

Thanks for testing,

I tested it with many different iPhones (from different users) and my own web-application under https. The owners of the iPhones had also checked their system preferences etc.

and I tested it with an iPhone and your appvisitor at https://www.captaincasademo.com/

It is very interesting that it works with the iPad you tested.

??? :/

hmmm ...

Thanks anyway! Holger

No problems with 14.7.1

Which CaptainCasa version are you using? There was an update to the JSQR component in Sept 2020 - because of problems on iOS.

If using a 2020-version: please update, best to the most current one.

Kind regards! Björn

PS: I even participated in the discussion on this: https://github.com/cozmo/jsQR/issues/185 , guess who "nettermensch" is ;-)

Hi,

you mentioned "I have searched hints for that in internet and found that this is fixed with a newer version of the component."

Could you please point me to the corresponding information? Thanks!

Hello,

yes, but it seems that's a litte bit old posting. But mayby it gives hints. The post is about the phenomenon of a black area, so I though it might be a problem of version.

Hi,

just had the chance to steel my son's iPhone...

Yes, there is a black area when iPhone accesses the camera... This is not only with the JSQR component but also with the normal CAMERA component. So the problem is accessing the camera.

The iPhone's version was 14.7.1.

So in iPad 14.7.1. no problem, but on iPhone 14.7.1 there is the problem you described. Why is Apple Safari so inconsistent????!!

We will follow up...

Regards, Björn

Hi Björn,

many thanks for your reply. Now we can assume that it has to do with the iPhone itself. I have tried the Chrome browser and Firefox as well. So I think that it also may not have to do with the browser but with the iPhone.

Kind regards, Holger

Hi Björn,

i've found a demo-page, where the component runs on iPhone in all browsers (firefox, chrome, safari) without black screen
