Question

How to check if the browser can play mp4 via html5 video tag?

Answer 1

This might help you:

<script type="text/javascript">'.    var canPlay = false;    var v = document.createElement('video');    if(v.canPlayType && v.canPlayType('video/mp4').replace(/no/, '')) {        canPlay = true;    }     alert(canPlay);  </script> 

Answer 2

Alex Polo's reply is not bad but incomplete try this to check if the codec is supported too:

var mp4Supported = (!!document.createElement('video').canPlayType('video/mp4; codecs=avc1.42E01E,mp4a.40.2')); 

Likewise for ogg, webm and so on ... Works with audio too :)
