title: Android - SurfaceTexture.updateTexImage and MediaPlayer
body: <p>I play a video with mediaPlayer and modify it using surfaceTexture and OpenGL ES 2.0. </p>
  
  <p>In the doc, it says that </p>
  
  <pre><code>surfaceTexture.updateTexImage();
  </code></pre>
  
  <p>will "update the texture image to the most recent frame from the image stream".</p>
  
  <p>So if I call 2 times updateTexImage, the texture image will not necessarily be the 2nd frame of the video ? </p>
  
  <p>If this is the case, then I guess there is no way to control the speed of the video with media player and OpenGL ?</p>
