NicEdit editor and youtube videos
===

I've used the nicEdit - http://nicedit.com/

I need to insert the videos from youtube. I need to insert only url for example: `http://www.youtube.com/watch?v=4GuqB1BQVr4` 

and replace to 

`<iframe width="560" height="315" src="http://www.youtube.com/embed/4GuqB1BQVr4" frameborder="0" allowfullscreen></iframe>`

How can i insert the videos from youtube using nicEdit?
