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.
TheHTMLMediaElement interface adds toHTMLElement the properties and methods needed to support basic media-related capabilities that are common to audio and video.
TheHTMLVideoElement andHTMLAudioElement elements both inherit this interface.

Instance properties
This interface also inherits properties from its ancestorsHTMLElement,Element,Node, andEventTarget.
HTMLMediaElement.audioTracksRead onlyAn
AudioTrackListthat lists theAudioTrackobjects contained in the element.HTMLMediaElement.autoplayA 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 theAutoplay 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 onlyReturns a
TimeRangesobject that indicates the ranges of the media source that the browser has buffered (if any) at the moment thebufferedproperty is accessed.HTMLMediaElement.controlsA boolean that reflects the
controlsHTML attribute, indicating whether user interface items for controlling the resource should be displayed.HTMLMediaElement.controlsListReturns 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.crossOriginA string indicating theCORS setting for this media element.
HTMLMediaElement.currentSrcRead onlyReturns a string with the absolute URL of the chosen media resource.
HTMLMediaElement.currentTimeA 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.
HTMLMediaElement.defaultMutedA boolean that reflects the
mutedHTML attribute, which indicates whether the media element's audio output should be muted by default.HTMLMediaElement.defaultPlaybackRateA
doubleindicating the default playback rate for the media.HTMLMediaElement.disableRemotePlaybackA boolean that sets or returns the remote playback state, indicating whether the media element is allowed to have a remote playback UI.
HTMLMediaElement.durationRead onlyA 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 onlyReturns a boolean that indicates whether the media element has finished playing.
HTMLMediaElement.errorRead onlyReturns a
MediaErrorobject for the most recent error, ornullif there has not been an error.HTMLMediaElement.loopA boolean that reflects the
loopHTML attribute, which indicates whether the media element should start over when it reaches the end.HTMLMediaElement.mediaKeysRead onlySecure contextReturns a
MediaKeysobject, that is a set of keys that the element can use for decryption of media data during playback. If no key is available, it can benull.HTMLMediaElement.mutedA boolean that determines whether audio is muted.
trueif the audio is muted andfalseotherwise.HTMLMediaElement.networkStateRead onlyReturns a
unsigned short(enumeration) indicating the current state of fetching the media over the network.HTMLMediaElement.pausedRead onlyReturns a boolean that indicates whether the media element is paused.
HTMLMediaElement.playbackRateA
doublethat indicates the rate at which the media is being played back.HTMLMediaElement.playedRead onlyReturns a
TimeRangesobject that contains the ranges of the media source that the browser has played, if any.HTMLMediaElement.preloadA string that reflects the
preloadHTML attribute, indicating what data should be preloaded, if any. Possible values are:none,metadata,auto.HTMLMediaElement.preservesPitchA 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 onlyReturns a
unsigned short(enumeration) indicating the readiness state of the media.HTMLMediaElement.remoteRead onlyReturn a
RemotePlaybackobject instance associated with the media element.HTMLMediaElement.seekableRead onlyReturns a
TimeRangesobject that contains the time ranges that the user is able to seek to, if any.HTMLMediaElement.seekingRead onlyReturns a boolean that indicates whether the media is in the process of seeking to a new position.
HTMLMediaElement.sinkIdRead onlySecure contextReturns 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.srcA string that reflects the
srcHTML attribute, which contains the URL of a media resource to use.HTMLMediaElement.srcObjectAn object which serves as the source of the media associated with the
HTMLMediaElement, ornullif not assigned.HTMLMediaElement.textTracksRead onlyReturns a
TextTrackListobject containing the list ofTextTrackobjects contained in the element.HTMLMediaElement.videoTracksRead onlyReturns a
VideoTrackListobject containing the list ofVideoTrackobjects contained in the element.HTMLMediaElement.volumeA
doubleindicating the audio volume, from 0.0 (silent) to 1.0 (loudest).
Obsolete properties
These properties are obsolete and should not be used, even if a browser still supports them.
HTMLMediaElement.controllerDeprecatedNon-standardA
MediaControllerobject that represents the media controller assigned to the element, ornullif none is assigned.HTMLMediaElement.mediaGroupDeprecatedNon-standardA string that reflects the
mediagroupHTML attribute, which indicates the name of the group of elements it belongs to. A group of media elements shares a commonMediaController.HTMLMediaElement.mozAudioCapturedRead onlyNon-standardDeprecatedReturns a boolean. Related to audio stream capture.
HTMLMediaElement.mozFragmentEndNon-standardDeprecatedA
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 ancestorsHTMLElement,Element,Node, andEventTarget.
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()Quickly seeks to the given time with low precision.
HTMLMediaElement.load()Resets the media to the beginning and selects the best available source from the sources provided using the
srcattribute or the<source>element.HTMLMediaElement.pause()Pauses the media playback.
HTMLMediaElement.play()Begins playback of the media.
HTMLMediaElement.seekToNextFrame()DeprecatedNon-standardSeeks to the next frame in the media. This non-standard, experimental method makes it possible to manually drive reading and rendering of media at a custom speed, or to move through the media frame-by-frame to perform filtering or other operations.
HTMLMediaElement.setMediaKeys()Secure contextReturns
Promise. Sets theMediaKeyskeys to use when decrypting media during playback.HTMLMediaElement.setSinkId()Secure contextSets the ID of the audio device to use for output and returns a
Promise. This only works when the application is authorized to use the specified device.
Obsolete methods
These methods are obsolete and should not be used, even if a browser still supports them.
HTMLMediaElement.mozCaptureStream()Non-standardThe Firefox-prefixed equivalent of
HTMLMediaElement.captureStream(). See itsbrowser compatibility for details.HTMLMediaElement.mozCaptureStreamUntilEnded()Non-standardDeprecated[enter description]
HTMLMediaElement.mozGetMetadata()Non-standardDeprecatedReturns
Object, which contains properties that represent metadata from the playing media resource as{key: value}pairs. A separate copy of the data is returned each time the method is called. This method must be called after theloadedmetadataevent fires.
Events
Inherits events from its parent,HTMLElement.
Listen to these events usingaddEventListener() or by assigning an event listener to theoneventname property of this interface.
abortFired when the resource was not fully loaded, but not as the result of an error.
canplayFired when the user agent can play the media, but estimates thatnot enough data has been loaded to play the media up to its end without having to stop for further buffering of content.
canplaythroughFired when the user agent can play the media, and estimates that enough data has been loaded to play the media up to its end without having to stop for further buffering of content.
durationchangeFired when the duration property has been updated.
emptiedFired when the media has become empty; for example, when the media has already been loaded (or partially loaded), and the
HTMLMediaElement.load()method is called to reload it.encryptedFired when initialization data is found in the media that indicates the media is encrypted.
endedFired when playback stops when end of the media (<audio> or <video>) is reached or because no further data is available.
errorFired when the resource could not be loaded due to an error.
loadeddataFired when the first frame of the media has finished loading.
loadedmetadataFired when the metadata has been loaded.
loadstartFired when the browser has started to load a resource.
pauseFired when a request to pause play is handled and the activity has entered its paused state, most commonly occurring when the media's
HTMLMediaElement.pause()method is called.playFired when the
pausedproperty is changed fromtruetofalse, as a result of theHTMLMediaElement.play()method, or theautoplayattribute.playingFired when playback is ready to start after having been paused or delayed due to lack of data.
progressFired periodically as the browser loads a resource.
ratechangeFired when the playback rate has changed.
seekedFired when a seek operation completes.
seekingFired when a seek operation begins.
stalledFired when the user agent is trying to fetch media data, but data is unexpectedly not forthcoming.
suspendFired when the media data loading has been suspended.
timeupdateFired when the time indicated by the
currentTimeproperty has been updated.volumechangeFired when the volume has changed.
