HTMLMediaElement.canPlayType()

The HTMLMediaElement.canPlayType() method determines whether the specified media type can be played back.

Note: This feature is not available in Web Workers.

Syntax

str = audioOrVideo.canPlayType(mediaType);

Parameters

mediaType
A DOMString containing the MIME type of the media.

Return value

A String. Possible values are:

  • 'probably': The specified media type appears to be playable.
  • 'maybe': Cannot tell if the media type is playable without playing it.
  • '' (empty string): The specified media type definitely cannot be played.

Note: Previously canPlayType('video/webm') returned 'probably'. Starting with Gecko 28 (Firefox 28 / Thunderbird 28 / SeaMonkey 2.25 / Firefox OS 1.3), it returns 'maybe'. (bug 884275)

Example

var obj = document.createElement('video');
console.log(obj.canPlayType('video/mp4')); // "maybe"
