QR-Code | program based on Java which generates QR Code | QRCode Processing library

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.

My code is -

I am using endroid/qr-code https://github.com/endroid/qr-code to generate QrCode. Now I need to send this QR to my email too.

I have used following codes:

While running the Pimcore6.9 along with the symfony4.4 I had spotted some warnings:

The MimetypeGuesser is depricated since symfony4.3 use MimeTypes instead.

Intergrate this for https://rapidapi.com/qrcode-monkey/api/custom-qr-code-with-logo

For this code

const express = require('express'); const http = require("https");

const router = express.Router();

router.post('/',async (req,res)=>{

console.log("req",req.body);

return res.sendStatus(200);

});

module.exports = router;

I want to do similar think like this ( How to generate QR CODE with logo in flutter ) but instead of using asset image, I want to user pick an image with image_picker package and then store that image in file and use it in QR code as an embedded image. Please anyone help me out.

Thank You

In our App we use a tab navigation and a stack navigation for each tab. We want an array of devices where we could add and delete devices. The array should be available on every tab.

This is our provider

I'm trying to create a simple html program that generates QR using external API. Basically, the JS creates QR for data supplied in field. eg: Data to be supplied for QR is :

For an academy project I have to find parts of a object (location / angle relative to the object ). The object is marked with a QR-code.

Currently I'm stuck on the basics. I scanned a room and load this room with "Spatial Object Mesh Observer".

But this observer gives no relevant information: The observer does not attempt to find 3D model LODs when sending the meshes to the application.

Someone a hint where I could start?

Friends, I need to redirect an URL (which doen't exist in the blog anymore) to another one in the same blog. How could I do this with the help of .htaccess?

The problem is that we have a printed QR-Code which leads people to this old URL which was in our old blog. We have another one now, using the same subdomain. Any idea?
