title: HTML5 video (mp4) not playing in iOS (nginx server)
body: <p>I am developing a website that features videos.</p>
  
  <p>I received reports that the videos are not playing on iOS, which I confirmed by using iOS Simulator.</p>
  
  <p>After several tests I noticed that:
  1- If I access this url <a href="http://www.w3schools.com/html/movie.mp4" rel="nofollow">http://www.w3schools.com/html/movie.mp4</a> using iOS Sim it plays fine.
  2- If I upload the same video to my server (nginx) and access it directly it does not play.</p>
  
  <p>I thought it was a MIME type issue but the Nginx mime.types has</p>

      video/x-msvideo                         avi;

  <p>Any suggestions? Is the iOS simulator (os x 10.9 latest xcode) reliable for these tests?</p>
