How to implement slider/progressbar for video app, YouTube style?

I want to revisit this question in 2013. As of Aug 13, 2013 youtube has a progress bar implemented at the top of the website. A redline crosses the screen from left to right at the place where the browser(probably bookmark bar for some) meets the actual website.
