About the YouTube video, it is not clear enough how he handle the QR value to have the image data.

Maybe the QR value itself contains a link to the image which is stored some else. Or maybe the QR value contains an ID that refers to a database record which retrieves the image form it.

However, check the following article that gives information on how to choose the right barcode for your requirement.

It might be customized to decode that code to image. Can you share that qr code for better understanding

I don't think it is possible because there is a limitation of characters in qr code. You can give a link that points to your image.

If it really needs to be encoded then it is possible to convert your image to base64 but I am not sure that it will maintain that character limit.

Furthermore, I also believe that no scanner will fetch that image during scan, you need to customize your application to decode that.

So its better to give a link of image
