I am trying to test google Duo on android tv running android version 5. Its not able to detect the camera.  Can you please guide me through the possible causes of this error. 
Could that error be because of external Camera not supporting android Device 
Could it be because of android firmware (every android tv manufacturer produce its own version of android tv). Does it require implementation or firmware to support external camera
Please guide me through those error
