The camera in the emulator, is it really possible to replace the standard one?

Question

Emulators

Hello gentlemen. The VPS has an emulator, namely bluestacks. The task is the following, you need to read the QR code of the WhatsApp application, and for this, logically, you need a camera.
From the ideas was:
start broadcasting the desktop and download any VCAM application in the emulator itself, for example, it catches a photo and I send it using it to read the QR. But the problem is that all programs that work with the camera require the original camera and do not agree to replace something.
Can you please tell me how to make this life come true?

Answer 1

Write a camera driver that outputs a captured image from the screen
