Variables

read only audioTracks:AudioTrackList

Is a AudioTrackList that lists the AudioTrack objects contained in the element.

autoplay:Bool

Is a Boolean that reflects the autoplay HTML attribute, indicating whether playback should automatically begin as soon as enough media is available to do so without interruption.

read only buffered:TimeRanges

Returns a TimeRanges object that indicates the ranges of the media source that the browser has buffered (if any) at the moment the buffered property is accessed.

controls:Bool

Is a Boolean that reflects the controls HTML attribute, indicating whether user interface items for controlling the resource should be displayed.

crossOrigin:String

Is a DOMString indicating the CORS setting for this media element.

read only currentSrc:String

Returns a DOMString with the absolute URL of the chosen media resource.

currentTime:Float

Is a double indicating the current playback time in seconds. Setting this value seeks the media to the new time.

defaultMuted:Bool

Is a Boolean that reflects the muted HTML attribute, which indicates whether the media element's audio output should be muted by default.

defaultPlaybackRate:Float

Is a double indicating the default playback rate for the media.

read only duration:Float

Returns a double indicating the length of the media in seconds, or 0 if no media data is available.

read only ended:Bool

Returns a Boolean that indicates whether the media element has finished playing.

read only error:MediaError

Returns a MediaError object for the most recent error, or null if there has not been an error.

loop:Bool

Is a Boolean that reflects the loop HTML attribute, which indicates whether the media element should start over when it reaches the end.

muted:Bool

Is a Boolean that determines whether audio is muted. true if the audio is muted and false otherwise.

read only networkState:Int

Returns a unsigned short (enumeration) indicating the current state of fetching the media over the network.

read only paused:Bool

Returns a Boolean that indicates whether the media element is paused.

playbackRate:Float

Is a double that indicates the rate at which the media is being played back.

read only played:TimeRanges

Returns a TimeRanges object that contains the ranges of the media source that the browser has played, if any.

preload:String

Is a DOMString that reflects the preload HTML attribute, indicating what data should be preloaded, if any. Possible values are: none, metadata, auto.

read only readyState:Int

Returns a unsigned short (enumeration) indicating the readiness state of the media.

read only seekable:TimeRanges

Returns a TimeRanges object that contains the time ranges that the user is able to seek to, if any.

read only seeking:Bool

Returns a Boolean that indicates whether the media is in the process of seeking to a new position.

src:String

Is a DOMString that reflects the src HTML attribute, which contains the URL of a media resource to use.

srcObject:MediaStream

Is a MediaStream representing the media to play or that has played in the current HTMLMediaElement.

read only textTracks:TextTrackList

Returns the list of TextTrack objects contained in the element.

read only videoTracks:VideoTrackList

Returns the list of VideoTrack objects contained in the element.

Note: Gecko supports only single track playback, and the parsing of tracks' metadata is only available for media with the Ogg container format.

volume:Float

Is a double indicating the audio volume, from 0.0 (silent) to 1.0 (loudest).

Methods

addTextTrack (kind:TextTrackKind, label:String = "", language:String = ""):TextTrack

Adds a text track (such as a track for subtitles) to a media element.

canPlayType (type:String):String

Determines whether the specified media type can be played back.

fastSeek (time:Float):Void

Throws:

null	DOMError

load ():Void

Resets the media element and restarts the media resource. Any pending events are discarded. How much media data is fetched is still affected by the preload attribute. This method can be useful for releasing resources after any src attribute and source element descendants have been removed. Otherwise, it is usually unnecessary to use this method, unless required to rescan source element children after dynamic changes.

pause ():Void

Throws:

null	DOMError

play ():Void

Throws:

null	DOMError
