I am working on a project with google cardboard, the idea of this project is just playing 360 video and viewing with google cardboard like the virtual tour (I have downloaded one of the 360 video from here http://www.kolor.com/360-video/gallery ).
i am doing this with creating a 3D sphere in unity and trying to put the video texture INSIDE the sphere, and also put the camera inside the sphere.
however, i have no idea how to put the video texture INSIDE the sphere and play it.
I’m trying to do the same thing…
Unfortunatly, I’ve seen that smartphone(android and IOs) cannot read MovieTexture, but only full-screen video (Unity - Manual: Movie Textures)…
For know I don’t know how solve that but I let you know when(if) I found a solution.
For your answer about reverse the texture you can follow this tutorial for oculus rift.
