title: Add a simulated camera to an Android device
body: <p>Short version : I'd like to add a simulated camera to an Android device.</p>
  
  <p>Long version : I am developing an Android app on two Android devices : A and B. I want the A's camera to send its stream to B, and I want B to handle it as if it was a camera of its own. So B would have this "fake camera" fed by A's stream. But this "fake camera" has to act like a real one.
  The connection between those two is done, the stream sending/receiving is correctly done, and I'm able to display it on B'screen. But I have no clue how to simulate it as an extra camera of the B's device.</p>
  
  <p>If you have any tips for me, I would be glad to ear about it.
  Thanks.</p>
  
  <p>PS : The stream sent/dreceived is a GLSurfaceView</p>
