OGG, MP4, FLV / SWF
<video width="320" height="240" controls> 
   <!-- Firefox --> 
   <source src="mv.ogg" type="video/ogg" />  
   <!-- Safari/Chrome-->   
   <source src="mv.mp4" type="video/mp4" />  
   <!-- if video tag is not supported then will use flash -->  
   <embed src="http://blip.tv/play/gcMVgcmBAgA%2Em4v" type="application/x-shockwave-flash"  
width="1024" height="798" allowscriptaccess="always" allowfullscreen="true"> </embed>  
</video>  

HTML5 video tag note
1, you need to create three video formats to implement support for Firefox, Safari / Chrome and IE;
2. Do not omit any kind of format. HTML 5 can not be as compatible as you think Firefox and Safari, Safari can explain video tag, would expect to load the appropriate file, if you omit certain format, it will cause the player to blank;
3. Remember that the full-screen display is not supported by Safari and Chrome. However, in Firefox 3.6 version, you can full screen browsing;
4. To understand why IE load Flash files, because IE does not explain video element. However, if the browser supports, is expected to load the appropriate file.
