HTMLMediaElement
Baseline
Widely available
*
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
* Some parts of this feature may have varying levels of support.
The HTMLMediaElement interface adds to HTMLElement the properties and methods needed to support basic media-related capabilities that are common to audio and video.
The HTMLVideoElement and HTMLAudioElement elements both inherit this interface.
Instance properties
This interface also inherits properties from its ancestors HTMLElement, Element, Node, and EventTarget.
HTMLMediaElement.audioTracksRead only-
An
AudioTrackListthat lists theAudioTrackobjects contained in the element. HTMLMediaElement.autoplay-
A boolean value that reflects the
autoplayHTML attribute, indicating whether playback should automatically begin as soon as enough media is available to do so without interruption.Note: Automatically playing audio when the user doesn't expect or desire it is a poor user experience and should be avoided in most cases, though there are exceptions. See the Autoplay guide for media and Web Audio APIs for more information. Keep in mind that browsers may ignore autoplay requests, so you should ensure that your code isn't dependent on autoplay working.
HTMLMediaElement.bufferedRead only-
Returns a
TimeRangesobject that indicates the ranges of the media source that the browser has buffered (if any) at the moment thebufferedproperty is accessed. HTMLMediaElement.controls-
A boolean that reflects the
controlsHTML attribute, indicating whether user interface items for controlling the resource should be displayed. HTMLMediaElement.controlsList-
Returns a
DOMTokenListthat helps the user agent select what controls to show on the media element whenever the user agent shows its own set of controls. TheDOMTokenListtakes one or more of three possible values:nodownload,nofullscreen, andnoremoteplayback. HTMLMediaElement.crossOrigin-
A string indicating the CORS setting for this media element.
HTMLMediaElement.currentSrcRead only-
Returns a string with the absolute URL of the chosen media resource.
HTMLMediaElement.currentTime-
A double-precision floating-point value indicating the current playback time in seconds; if the media has not started to play and has not been seeked, this value is the media's initial playback time. Setting this value seeks the media to the new time. The time is specified relative to the media's timeline.

A boolean that reflects the
mutedHTML attribute, which indicates whether the media element's audio output should be muted by default. HTMLMediaElement.defaultPlaybackRate-
A

A boolean that sets or returns the remote playback state, indicating whether the media element is allowed to have a remote playback UI.
HTMLMediaElement.durationRead only-
A read-only double-precision floating-point value indicating the total duration of the media in seconds. If no media data is available, the returned value is
NaN. If the media is of indefinite length (such as streamed live media, a WebRTC call's media, or similar), the value isInfinity. HTMLMediaElement.endedRead only-
Returns a boolean that indicates whether the media element has finished playing.

trueif the audio is muted andfalseotherwise. HTMLMediaElement.networkStateRead only-
Returns a
unsigned short(enumeration) indicating the current state of fetching the media over the network. HTMLMediaElement.pausedRead only-
Returns a boolean that indicates whether the media element is paused.
HTMLMediaElement.playbackRate-
A

A string that reflects the
preloadHTML attribute, indicating what data should be preloaded, if any. Possible values are:none,metadata,auto. HTMLMediaElement.preservesPitch-
A boolean value that determines if the pitch of the sound will be preserved. If set to
false, the pitch will adjust to the speed of the audio. HTMLMediaElement.readyStateRead only-
Returns a
unsigned short(enumeration) indicating the readiness state of the media. HTMLMediaElement.remoteRead only-
Return a
RemotePlaybackobject instance associated with the media element. HTMLMediaElement.seekableRead only-
Returns a
TimeRangesobject that contains the time ranges that the user is able to seek to, if any. HTMLMediaElement.seekingRead only-
Returns a boolean that indicates whether the media is in the process of seeking to a new position.
HTMLMediaElement.sinkIdRead only Secure context-
Returns a string that is the unique ID of the audio device delivering output, or an empty string if the user agent default audio device is being used.
HTMLMediaElement.src-
A string that reflects the
srcHTML attribute, which contains the URL of a media resource to use. HTMLMediaElement.srcObject-

Obsolete properties
These properties are obsolete and should not be used, even if a browser still supports them.
HTMLMediaElement.controllerDeprecated Non-standard-

Returns a boolean. Related to audio stream capture.
HTMLMediaElement.mozFragmentEndNon-standard Deprecated-
A
doublethat provides access to the fragment end time if the media element has a fragment URI forcurrentSrc, otherwise it is equal to the media duration.
Instance methods
This interface also inherits methods from its ancestors HTMLElement, Element, Node, and EventTarget.
HTMLMediaElement.addTextTrack()-
Adds a new
TextTrackobject (such as a track for subtitles) to a media element. This is a programmatic interface only and does not affect the DOM. HTMLMediaElement.captureStream()-
Returns
MediaStream, captures a stream of the media content. HTMLMediaElement.canPlayType()-
Given a string specifying a MIME media type (potentially with the
codecsparameter included),canPlayType()returns the stringprobablyif the media should be playable,maybeif there's not enough information to determine whether the media will play or not, or an empty string if the media cannot be played. HTMLMediaElement.fastSeek()-

HTMLMediaElement.setMediaKeys()Secure context-
Returns
Promise. Sets theMediaKeyskeys to use when decrypting media during playback. HTMLMediaElement.setSinkId()Secure context-
