Get HTML5 Video Duration
HTML5 video is exciting, if only for the reason that we no longer need Flash or other third party plugins to render media. We can also create custom controls and displays around the video, and one of those displays should be the duration of the video. Let me show you how to get and display the video duration!
The JavaScript
video elements have a duration property which represents the number of seconds in the video. To display the duration in a pretty fashion, you'll need to use parseInt and modulus (%):
// Assume "video" is the video node
var i = setInterval(function() {
if(video.readyState > 0) {
var minutes = parseInt(video.duration / 60, 10);
var seconds = video.duration % 60;
// (Put the minutes and seconds in the display)
clearInterval(i);
}
}, 200);
It's important to use setInterval and check the video's readyState in case the video hasn't loaded by the time you attempt to pull the duration. parseInt is used to get the minute number and modulus is used to get the second count.

Feature detection via JavaScript is a client side best practice and for all the right reasons, but unfortunately that same functionality hasn't been available within CSS. What we end up doing is repeating the same properties multiple times with each browser prefix. Yuck. Another thing we...

There are two events you can use instead of an interval
a)
loadedmetadatab)
durationchangeOf course you still need to check
readyStateinitially.(function(){ var video = document.querySelector('video'); var onDurationChange = function(){ if(video.readyState){ //to your thing } }; video.addEventListener('durationchange', onDurationChange); onDurationChange(); })();You need to divide video duration by 60 to get minutes, then use parseInt with radix 10. We should test if video duration > 0 before our division.

if (video.duration > 0) { var minutes = parseInt(video.duration / 60, 10); var seconds = video.duration % 60; }David,

Thanks for the great articles!
Since when (and on which platforms)
setIntervalpasses the interval ID as argument to the callback function?HTML5 video is really great, gone are the days struggling with Flash codes and easily display our videos. Thanks for the JS code.
Thanks for the code! What if I want also to get the hours and display them as a
HH:mm:ssformat accordingly?I m trying to buid the video using jquery. Please help to fetch the video duration before loaded
var video=$(''); var source= $(''); $(source).appendTo(video); $(source).attr('src',php.mp4); $(source).attr('type','video/mp4'); //var d= $(video).duration; var d=document.querySelector('video').duration; console.log(d);You could just use the javascript
whilefunction…while (true) { if (video.readyState) { //blabla code break; } //code to execute if not accomplished }
