// 2. The HTMLMediaElement doesn't always hold a WebMediaPlayer instance while
//    static function does't work here because it cannot be override in
//    inherited classes like WebMediaPlayerImpl.

// This function can return "", "maybe" or "probably" as defined in
// http://www.w3.org/TR/html5/embedded-content-0.html#dom-navigator-canplaytype
// to indicate how certain that the particular implementation can play videos in
// the format specified by content_type and key_system. Note that "" means the
// implementation cannot play such videos.
