Controls for Web Videos Using Bookmarklet

Few years ago I had an urge to watch all the videos with higher speed to save the time. However not all the web players do have controls to speed up or slow down the video. No need to worry, there is a remedy! The simplest solution I found was usage of bookmarklets: bookmark in your browser that has the URL filled with a piece of javascript code. With the right code you can manipulate the <video>s present in the web page.
