title: Maximum duration (or file size) of html5 video
body: <p>I'm trying to use a custom html5 player with a 4-hour long video (2.3 GB!), but I'm getting some problems: playback stops, video seeking doesn't seem to work well and so on.</p>
  
  <p>Using the native player of the browser, I have the same issues.</p>
  
  <p>So I was wondering: are there any recommendations about the maximum duration (or file size) of a video in html5? What about mobile devices?</p>
