La interfaz HTMLMediaElement añade a HTMLElement las propiedades y métodos necesarios para soportar las capacidades básicas relacionadas con los medios de comunicación que son comunes en audio y vÃdeo. Los elementos HTMLVideoElement y HTMLAudioElement heredan esta interfaz.
must be a string
PropertiesEsta interfaz también hereda propiedades de sus antepasados HTMLElement, Element, Node y EventTarget.
HTMLMediaElement.audioTracks
Un AudioTrackList que lista los AudioTrack objetos contenidos en el elemento.
HTMLMediaElement.autoplay
Un Booleano que refleja el autoplay. Atributo HTML, que indica si la reproducción debe comenzar automáticamente tan pronto como haya suficiente material disponible para hacerlo sin interrupción.
Nota: Los sitios que reproducen automáticamente audio (o vÃdeos con una pista de audio) pueden ser una experiencia desagradable para los usuarios, por lo que deben evitarse en la medida de lo posible. Si debe ofrecer la funcionalidad de autojuego, debe hacer que se active (requiriendo que el usuario lo habilite especÃficamente). Sin embargo, esto puede ser útil a la hora de crear elementos multimedia cuya fuente se establecerá más adelante, bajo el control del usuario.
HTMLMediaElement.buffered Read only
Devuelve un objeto TimeRanges que indica los rangos de la fuente de medios que el navegador ha almacenado en el búfer (si existe) en el momento en que se accede a la propiedad almacenada en el búfer.
HTMLMediaElement.controller
Es un objeto MediaController que representa el controlador de medios asignado al elemento, o nulo si no se asigna ninguno.
HTMLMediaElement.controls
Es un booleano que refleja el controles[1]. Atributo HTML, que indica si deben visualizarse las posiciones de la interfase de usuario para controlar el recurso.
HTMLMediaElement.controlsList Read only
Devuelve un DOMTokenList que ayuda al agente de usuario a seleccionar qué controles mostrar en el elemento multimedia cuando el agente de usuario muestra su propio conjunto de controles. La DOMTokenList toma uno o más de los tres valores posibles: nodownload, nofullscreen y noremoteplayback.
HTMLMediaElement.crossOrigin
Es un DOMString que indica la configuración CORS para este elemento multimedia.
HTMLMediaElement.currentSrc Read only
Devuelve un DOMString con la URL absoluta del recurso multimedia elegido.
HTMLMediaElement.currentTime
Es un doble indicador del tiempo de reproducción actual en segundos. Fijar este valor busca que los medios de comunicación se adapten a los nuevos tiempos.
HTMLMediaElement.defaultMuted
Es un booleano que refleja el silenciado. Atributo HTML, que indica si la salida de audio del elemento multimedia debe silenciarse de forma predeterminada.
HTMLMediaElement.defaultPlaybackRate
Es un doble que indica la velocidad de reproducción predeterminada del material.
HTMLMediaElement.disableRemotePlayback
Es un Booleano que establece o devuelve el estado de reproducción remota, indicando si el elemento multimedia puede tener una interfaz de reproducción remota.
HTMLMediaElement.duration Read only
Devuelve un doble indicando la longitud del material en segundos, o 0 si no hay datos de material disponibles.
HTMLMediaElement.ended Read only
Devuelve un Booleano que indica si el elemento multimedia ha terminado de reproducirse.
HTMLMediaElement.error Read only
Returns a MediaError object for the most recent error, or null if there has not been an error.
HTMLMediaElement.loop
Is a Boolean that reflects the loop HTML attribute, which indicates whether the media element should start over when it reaches the end.
HTMLMediaElement.mediaGroup
Is a DOMString that reflects the mediagroup HTML attribute, which indicates the name of the group of elements it belongs to. A group of media elements shares a common MediaController.
HTMLMediaElement.mediaKeys Read only Experimental
Returns a MediaKeys object or null. MediaKeys is a set of keys that an associated HTMLMediaElement can use for decryption of media data during playback.
HTMLMediaElement.mozAudioCaptured Read only No estándar
Returns a Boolean. Related to audio stream capture.
HTMLMediaElement.mozFragmentEnd No estándar
Is a double that provides access to the fragment end time if the media element has a fragment URI for currentSrc, otherwise it is equal to the media duration.
HTMLMediaElement.mozFrameBufferLength No estándar Obsoleto
Is a unsigned long that indicates the number of samples that will be returned in the framebuffer of each MozAudioAvailable event. This number is a total for all channels, and by default is set to be the number of channels * 1024 (e.g., 2 channels * 1024 samples = 2048 total).
The mozFrameBufferLength property can be set to a new value for lower latency, larger amounts of data, etc. The size given must be a number between 512 and 16384. Using any other size results in an exception being thrown. The best time to set a new length is after the loadedmetadata event fires, when the audio info is known, but before the audio has started or MozAudioAvailable events have begun firing.
HTMLMediaElement.mozSampleRate Read only No estándar Obsoleto
Returns a double representing the number of samples per second that will be played. For example, 44100 samples per second is the sample rate used by CD audio.
HTMLMediaElement.muted
Is a Boolean that determines whether audio is muted. true if the audio is muted and false otherwise.
HTMLMediaElement.networkState Read only
Returns a unsigned short (enumeration) indicating the current state of fetching the media over the network.
HTMLMediaElement.paused Read only
Returns a Boolean that indicates whether the media element is paused.
HTMLMediaElement.playbackRate
Is a double that indicates the rate at which the media is being played back.
HTMLMediaElement.played Read only
Returns a TimeRanges object that contains the ranges of the media source that the browser has played, if any.
HTMLMediaElement.preload
Is a DOMString that reflects the preload HTML attribute, indicating what data should be preloaded, if any. Possible values are: none, metadata, auto.
HTMLMediaElement.preservesPitch No estándar
Is a Boolean 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. This is implemented with prefixes in Firefox (mozPreservesPitch) and WebKit (webkitPreservesPitch).
HTMLMediaElement.readyState Read only
Returns a unsigned short (enumeration) indicating the readiness state of the media.
HTMLMediaElement.seekable Read only
Returns a TimeRanges object that contains the time ranges that the user is able to seek to, if any.
HTMLMediaElement.seeking Read only
Returns a Boolean that indicates whether the media is in the process of seeking to a new position.
HTMLMediaElement.sinkId Read only Experimental
Returns a DOMString that is the unique ID of the audio device delivering output, or an empty string if it is using the user agent default. This ID should be one of the MediaDeviceInfo.deviceid values returned from MediaDevices.enumerateDevices(), id-multimedia, or id-communications.
HTMLMediaElement.src
Is a DOMString that reflects the src HTML attribute, which contains the URL of a media resource to use.
HTMLMediaElement.srcObject
Is a MediaStream representing the media to play or that has played in the current HTMLMediaElement, or null if not assigned.
HTMLMediaElement.textTracks Read only
Returns the list of TextTrack objects contained in the element.
HTMLMediaElement.videoTracks Read only
Returns the list of VideoTrack objects contained in the element.
Nota: Gecko sólo soporta la reproducción de una sola pista, y el análisis de los metadatos de las pistas sólo está disponible para los medios con el formato de contenedor Ogg.
HTMLMediaElement.volume
Is a double indicating the audio volume, from 0.0 (silent) to 1.0 (loudest).
HTMLMediaElement.onencrypted
Sets the EventHandler called when the media is encrypted.
HTMLMediaElement.onwaitingforkey
Sets the EventHandler called when playback is blocked while waiting for an encryption key.
These attributes are obsolete and should not be used, even if a browser still supports them.
HTMLMediaElement.initialTime Read only No estándar Obsoleto
Returns a double that indicates the initial playback position in seconds.
HTMLMediaElement.mozChannels Read only No estándar Obsoleto
Returns a double representing the number of channels in the audio resource (e.g., 2 for stereo).
HTMLMediaElement.onmozinterruptbegin No estándar Obsoleto
Sets the event handler called when the media element is interrupted because of the Audio Channel manager. This was Firefox-specific, having been implemented for Firefox OS, and was removed in Firefox 55.
HTMLMediaElement.onmozinterruptend No estándar Obsoleto
Sets the EventHandler called when the interruption is concluded. This was Firefox-specific, having been implemented for Firefox OS, and was removed in Firefox 55.
This interface also inherits methods from its ancestors HTMLElement, Element, Node, and EventTarget.
HTMLMediaElement.addTextTrack()
Adds a text track (such as a track for subtitles) to a media element.
HTMLMediaElement.captureStream() Experimental
Returns MediaStream, captures a stream of the media content.
HTMLMediaElement.canPlayType()
Determines whether the specified media type can be played back.
HTMLMediaElement.fastSeek()
Directly seeks to the given time.
HTMLMediaElement.load()
Resets the media to the beginning and selects the best available source from the sources provided using the src attribute or the <source> element.
HTMLMediaElement.mozCaptureStream() No estándar
[enter description]
HTMLMediaElement.mozCaptureStreamUntilEnded() No estándar
[enter description]
HTMLMediaElement.mozGetMetadata() No estándar
Returns 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 the loadedmetadata event fires.
HTMLMediaElement.pause()
Pauses the media playback.
HTMLMediaElement.play()
Begins playback of the media.
HTMLMediaElement.seekToNextFrame() No estándar Experimental
Seeks 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() Experimental
Returns Promise. Sets the MediaKeys keys to use when decrypting media during playback.
HTMLMediaElement.setSinkId() Experimental
Sets 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.
These methods are obsolete and should not be used, even if a browser still supports them.
HTMLMediaElement.mozLoadFrom() No estándar Obsoleto
This method, available only in Mozilla's implementation, loads data from another media element. This works similarly to load() except that instead of running the normal resource selection algorithm, the source is simply set to the other element's currentSrc. This is optimized so this element gets access to all of the other element's cached and buffered data; in fact, the two elements share downloaded data, so data downloaded by either element is available to both.
