title: How do videos autoplay on iOS at youtube.com
body: <p>When I set autoplay to true for a YouTube video (IFrame API) on my site, it doesn't work. All the documentation says apple disables autoplay on ios for bandwidth reasons. </p>
  
  <p>However, I see that videos play automatically (without clicking on the video element) on youtube.com on iPad. How did YouTube make it work? It would be hard to imagine Apple does something special just for YouTube.</p>
