How to use a PC webcam as the emulator's camera

Question

I'm developing a qr code reader application. How can I use my webcam as a camera to scan the qr code in the emulator ?

my SDK version is 4.3. I checked it out in developer.android site and they said that you have to select webcam0 as a back camera. I tried but it didn't work, and shows "unfortunately your app has been stopped".

Use the Camera tab in Extended controls to add or modify Scene images. There are two image locations, one on the wall and one on the table.

To view these image locations in the scene, launch your emulator, then move the camera to the dining room area through the door behind the camera’s starting position. https://developers.google.com/ar/develop/java/emulator#add_augmented_images_to_the_scene
