The features of this script:
The bar smoothly progress with animation on less than 4 min. videos.
The animation is not noticable in longer than 4 min. videos, so it is disabled for less computer load.
The animated bar is also available in ads.
It highlights the buffered range, like YouTube's default.
It is available for embedded videos on other sites than YouTube.
It doesn't show the bar of the script on LIVE streamings.
