There are apps like splashtop to stream content from the pc to a smartphone but of course that is not optimized and will have big latency in VR.
There will be optimized streaming solutions within the oculus store like im360VR, Next VR and Samsungs Project Beyond camera. But if you want to watch your own videos in the oculus cinema, you can just do that by putting them onto the sd card of the Note 4.
Actually, Trinus Gyre does what I originally created this post for. At least, the PC aspect of it!
