Video Duration and Current Play Time Programming Tutorial
In this 3rd part of customizing the HTML5 video controls we will demonstrate how you can show the current play time and the full video duration time the way youtube videos display video current time and duration. We can use the currentTime and duration properties of the video object and convert them to minutes and seconds for display purposes.
