What is the best way to display stereoscopic video file in Unity 5.6?

Hello. I wonder if there is a good way to display the stereoscopic video on Unity5.6. My current idea is create 2 spheres and 2 cameras for both eyes and use culling to not show the other side. Since the Unity 5.6 supporting the VR, I usually don't need to place 2 cameras for headset and it automatically does for me. I was wondering if there is a way to use culling for each eyes without duplicating the sphere and cameras...

Thank you.
