HTML5 Player Comparison http://bit.ly/9l0fs3
A good listing of features for HTML5 players that allow you to add features beyond basic browser playback, including full screen. Many are iOS compatible and will fall back to use Flash if the browser doesn’t support HTML5 or the format of your video isn’t supported under HTML5 on specific browsers. For example, if you format to MP4 H264 supported by Chrome, Safari and IE9, you’ll get a Flash player fallback on Firefox.
