how to use a remote camera (webcam or Windows-usb) as my Android built-in camera(s) Please read carefully, there are MANY answers to the 'opposite' question from the one I ask here, but I cannot find an answer to the following question:

I have an android device with no built-in camera.  I want to be able to use a REMOTE camera as the "built-in" camera on this android device.  The remote camera could be a (streaming)webcam, or it could be a USB cam attached to a PC.

My requirement is that the android device i use "think" that it has a camera built-in (or even better, two cameras, a front- and rear-facing one), so that I can use Skype, and zoom, and all other camera apps. 

I am happy to also need to install software on the remote device where the camera is physically attached.  That remote device is really a windows PC, but if necessary, i could perhaps have it be a Linux box. 

Please note that I do NOT need to 'turn' my android camera into a webcam. That is "easy" -- except that I don't have an android camera. That is why i need to do the opposite.  I would be fine to use a very generic solution, for example a "net-usb" client server solution, which would give me a usb-camera on my android. But the solutions i have seen like that are VERY expensive.

Thank you for any help/pointers you can give me.

PS ("the truth") -- the truth is that I would like to run Skype and Zoom on an android-86 running within a Windows HyperVisor. Unfortuantely, Windows HyperV seems not to support USB, and so i don't know how to add a 'built-in' camera to the android-x86 which I have already running there. Therefore, i can not use SKype or Zoom, since I don't have a camera 'built-in' to this machine.
I'm not sure about using a 'remote' camera, but as for a USB camera I've found a simple solution for myself as I was having a similar issue. Enable USB 2.0 and go into the Devices tab and Webcams and click on your webcam (assuming it's detected) prior to installing your operating system. This worked great for me with android x86 7.1 RC2
