QR code recognition?

[alekop]

I am trying to add QR reader support to an existing app that uses the zxing library. It can scan QR codes when running on electron, but not on iOS (14.8). The camera stream comes up, but it doesn't detect QR codes. Is that a limitation of the plugin?

This plugin does not support out of the box Stream to Canvas that is required by most image processing, see this reply for drawing video on canvas using iOSRTC- #721 (comment)

I think you need to capture video frames by yourself.

Get the image frame data and then decode the base64

video.render.save(function (data) {
            });

I have created a scanner with Dynamsoft Barcode Reader: https://github.com/xulihang/cordova-barcode-scanner
