It doesn't work for me. How does it work? What do you put in 'id'?

wiki:
You will need the YouTube id of the video - an easy way to get this for a YouTube video is to find the video you want and click Share. The id will be displayed at the end of a URL like http://youtu.be/qDlakzXcnro where "qDlakzXcnro" is the id you want.
