title: HTML5 video formats - compatibility
body: <p>So, I'm building a website on which users can upload an watch videos.
  I'm using the standard HTML5 video player (<code>&lt;video...&gt; &lt;src&gt;...</code>)
  Currently, I use multiple sources: MP4, OGG and WEBM, for cross-browser compatibility</p>
  
  <p>Due to the fact that maintaining three formats is both CPU intensive (converting) as well as eating away precious disk space, I started searching the need to find out whether it's really needed to support this three formats</p>
  
  <p>According to the chart I found on Wikipedia (<a href="http://en.wikipedia.org/wiki/HTML5_video" rel="noreferrer">http://en.wikipedia.org/wiki/HTML5_video</a>),
  OGG and MP4 should be sufficient, as all browsers seem to be supporting at least one of these formats</p>
  
  <p>... or am I missing something?</p>
