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

问题:

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".

3. Hardware > New:
4. Configures camera facing back
5. Click on the property value and choose = "webcam0".
6. Once done all the above the webcam should be connected. If it doesnt then you need to check your WebCam drivers.
