title: How does Vine looping video playback work on iOS?
body: <p>Vine loops videos without any pauses in between loops. I've tried creating an <code>AVPlayer</code> that plays the video from the beginning whenever it ends. This introduces a slight lag between every loop. I'm looking for suggestions of ways to avoid this lag.</p>
  
  <p>I have considered creating much longer videos out of repeating short clips. Am I missing some obvious solution?</p>
  
  <p>Thanks.</p>
