What happens when you click on a embedded YouTube video? Well, if it’s not running, video will start playing, else a click on the video’ll open a YouTube's page, and the video will start playing from begining. Now, YouTube's player is smarter: First, the click on the video pauses it, and opens a YouTube page that continues to play the video seamlessly and adds a parameter #t=. For e.g. try the new feature using the video embedded below, you'll notice that YouTube uses a URL format: http://www.youtube.com/watch?v=Umj1lvgoI68#t=1m15s (where 1m15s is the start time). Another change’s, now when click on the player, YouTube pauses the video.
