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
DOMStringcontaining 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"
