Video for Everybody is very simply a chunk of HTML code that embeds a video into a website
using the HTML5 <video> element which offers native playback in Firefox
3.5 and Safari 3 & 4.

In other browsers that do not support <video>, it falls
back to Adobe Flash.

If Flash is not installed, QuickTime is used (which allows playback on the iPhone).

If QuickTime is not installed then Windows Media Player is used in Internet
Explorer for Windows Vista and above. This means that it is actually almost impossible for the
video to not play in IE on Vista / Windows 7. Even
without Flash and QuickTime, you’d have to disable Windows Media Player or
all ActiveX entirely!
Finally, if all else fails, a warning is issued that provides links to download the video, and links to software
relevant to getting the video to play within the browser itself. Since this is just HTML, you can put
anything here you want.
