            QR Scanner npm library throwing errors for chrome
            Asked 2021-May-31 at 20:53

            I am using the library https://github.com/felipenmoura/qr-code-scanner to implement scanning of the QR codes. I am facing two problems -

            1. Google chrome throws the following error whenever I click the button to trigger. The library works fine on Safari.

            Uncaught (in promise) OverconstrainedError {name: "OverconstrainedError", message: "", constraint: "facingMode"}constraint: "facingMode"message: ""name: "OverconstrainedError"__proto__: OverconstrainedError

            1. The camera feed doesn't work for mobile phones (both safari and chrome). It opens the camera, and doesn't show the live feed, instead it keeps on showing a static image

            I am not sure if this is the best library for QR code scanning. My aim is to implement a button that triggers the camera, scans QR,enter image description here and puts the scanned string into the input field.

            I think it is because of your imports

            you need to change your import from android.support.v4.app.Fragment to android.app.Fragment or vice versa

            The ZXing library is no longer maintained, and that particular class (IntentIntegrator) only supports android.app.Fragment which is the deprecated Android framework version of the AndroidX Fragment class.

            You have a few possible options here:

            1. Fork the ZXing library, and change the android.app.Fragment import to use the androidx.fragment.app.Fragment version instead.

            2. Delegate the IntentIntegrator calls to your Activity instead, and have the results forwarded to your Fragment.

            3. Simply duplicate the Intent initialization code from IntentIntegrator to a helper class of your own. The IntentIntegrator methods are just convenience methods to build an Intent and call startActivityForResult(). You'll still be able to use the IntentIntegrator.parseActivityResult method to interpret the result that comes back.

            I would recommend going with option #3.

            As a longer term alternative, you may also want to consider looking into Firebase ML Kit since ZXing is no longer maintained.

            How to add event in Calendar when scanned by QR scanner in swift iOS

            Before posted I did search for this answer but didn't find what I need so would like to ask if you kindly can help me.

            I have iOS Swift app that scans QR codes which is in my case calendar event then show it as alert popup. What I need is to scan QR Code (calendar event) and when scanned prompt if Event will be added into calendar, also limit scanning to event QR Codes.

            Code that worked was from https://medium.com/@gayatri.hedau/qr-code-scanner-with-avcapturesession-ios-swift-5007ee498b49, but there you can just confirm that you have seen scanned info.

            QR code with event info is created on https://qrcode.tec-it.com/en/Calendar

            I don't know so much but I think that bellow part of code should be adjusted as this part shows alert QR code.

            How to configure c++ Zbar scanner to decode only QR-Code data type?
            Asked 2019-May-31 at 19:38

            I am using Zbar C++ library to decode QRCode,using this tutorial: https://www.learnopencv.com/barcode-and-qr-code-scanner-using-zbar-and-opencv/

            Here I have to decode only QRCode from an image however using this tutorial it decodes both QRcode and barcodes from an Image.

            In tutorial it says to decode only QRCode we have to Configure Zbar Imagescanner properly.

            In tutorial they are using following configuration to decode both QRCode and Barcodes ImageScanner scanner; scanner.set_config(ZBAR_NONE, ZBAR_CFG_ENABLE, 1);

            So to decode only QRCode I am using following configuration: ImageScanner scanner; scanner.set_config(ZBAR_QRCODE, ZBAR_CFG_ENABLE, 1);

            But using this Zbar configuration still it decodes both QRCode and barcodes data.I am getting Decoded Data type as EAN-13 and QR-Code.

            How I can configure Zbar sccanner properly so it decodes only QR-Code Data type?
