This is probably a slightly peculiar question that I am posting here.
I need a bare minimum android emulator for windows that would be able to take a webcam as an input. I have developed an augmented reality application using Vuforia and Unity3d. Compiled application only works for android because of the Vuforia, however I would need it on a windows 7. I have tried it on a Bluestack emulator and it works fine, I have also tested several other emulators. Typically webcam input does not work or it has 1 second delay. Bluestack seems to be fine, but I would require something that requires less computer resources than Bluestack.
