title: Exoplayer - can you call seekTo() while buffering?
body: <p>I have an ExoPlayer instance, and a seekbar. When the user seeks, I'd like to use <code>ExoPlayer.seekTo()</code> to update the position of the video.</p>
  
  <p>Can you call <code>ExoPlayer.seekTo()</code> as frequently as you want, and it should handle canceling previous <code>seekTo()</code> requests if they haven't finished? Or do we have to prevent ovelapping <code>seekTo()</code> calls ourselves?</p>
  
  <p>Thanks</p>
