title: Android: render textureview of 2D video in side-by-side
body: <p>I am trying to create an video player app which is capable of displaying a 2D video in a side-by-side projection for cardboard. The input is a 2D video, so no need for head tracking. I checked the Google Cardboard SDKs but they don't provide an implementation for simple side-by-side projections with Non-3D or 360° contents.</p>
  
  <p>My current implementation of the video player already uses a <code>TextureView</code> to render the video.</p>
  
  <p>I found a sample code for side-by-side-camera preview: <a href="https://stackoverflow.com/questions/27881389/android-side-by-side-camera">[android Side By Side Camera</a></p>
  
  <p>How do I get the output from the <code>TextureView</code> of my video player into a <code>GvrView</code>?</p>
