    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"
