How can I cast my android's phone screen running a VR application to my desktop ?


I’m developing an application with Unreal Engine 4 in VR for android. I would like to cast what players can see in a 2D screen without seeing a splitscreen like a regular screencast. I saw that’s possible with occulus but I’m working with GoogleVR and google Cardboard. Should I implement a local “multiplayer” with a single camera following the direction of the player or are there easiest ways to do it ?

Thanks in advance for your assistance.
