title: How to use webcam to scan barcode?
body: <p>I need to make an android app in which, I need to scan the barcode. But the issue is that I do not have an android phone and plan to use the emulator. I was wondering if I could use my webcam to scan the barcode and then feed it to my program to make this work. Are there any available open source libraries which allow me to do so? To be able to read qr code through the same would be a bonus.</p>
