title: How to display a 360 video frame by frame, for a desktop VR app in Unity?
body: <p>Is it possible to control a 360 degrees video to move forward or backward in time (frame +/- 1) by the means of an event, like pressing a controller button?</p>
  
  <p>The idea here is to have an environment extracted from a video. The video should not play. When pressing a button, we can go to the next/previous frame.</p>
  
  <p>Is there some documentation on this? I only found the <a href="https://github.com/Unity-Technologies/SkyboxPanoramicShader/blob/master/Skybox-PanoramicBeta.shader" rel="noreferrer">Skybox-PanoramicBeta.shader</a>.</p>
