HTML5 video tag

 I was looking at  HTML5 VIDEO tag and it turned out it's a mess.
  Patents and conflicting interests made this into a situation that you have to encode your video into 3 formats to be sure that will play at least in modern browsers; older browsers are even bigger mess.

•  MP4 will work in IE, and that's pretty much only one that will work there. 
•  Ogg/Theora is neccessary for Firefox and will work in Opera too.
• Webm is supported by Chrome but Google can drop that format any time since they bought the company that created the format.

After you encode your movie, you have to set up IIS to recognize all 3 of those formats or you will get nice red X instead of the movie.

 Under Mime types in IIS Feature View, you need to add:

1. extension .mp4
   type: video/mp4
2.  extension .ogv
    type: video/ogg
3.  extension .webm
    type: video/webm

Android needs extra help, as per http://www.broken-links.com/2010/07/08/making-html5-video-work-on-android-phones/

<script type="text/javascript">
  var video = document.getElementById('video');
  video.addEventListener('click',function(){
    video.play();
  },false);
</script>
