MediaStream extension type

The MediaStream interface of the Media Capture and Streams API represents a stream of media content. A stream consists of several tracks, such as video or audio tracks. Each track is specified as an instance of MediaStreamTrack.

You can obtain a MediaStream object either by using the constructor or by calling functions such as MediaDevices.getUserMedia, MediaDevices.getDisplayMedia, or HTMLCanvasElement.captureStream and HTMLMediaElement.captureStream.

Methods

addEventListener(String type, EventListener? callback, [JSAny options]) → void
The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.
inherited
addTrack(MediaStreamTrack track) → void
The addTrack() method of the MediaStream interface adds a new track to the stream. The track is specified as a parameter of type MediaStreamTrack.
clone() → MediaStream
The clone() method of the MediaStream interface creates a duplicate of the MediaStream. This new MediaStream object has a new unique MediaStream.id and contains clones of every MediaStreamTrack contained by the MediaStream on which clone() was called.
dispatchEvent(Event event) → bool
The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().
inherited
getAudioTracks() → JSArray<MediaStreamTrack>
The getAudioTracks() method of the MediaStream interface returns a sequence that represents all the MediaStreamTrack objects in this stream's track set where MediaStreamTrack.kind is audio.
getTrackById(String trackId) → MediaStreamTrack?
The getTrackById() method of the MediaStream interface returns a MediaStreamTrack object representing the track with the specified ID string. If there is no track with the specified ID, this method returns null.
getTracks() → JSArray<MediaStreamTrack>
The getTracks() method of the MediaStream interface returns a sequence that represents all the MediaStreamTrack objects in this stream's track set, regardless of MediaStreamTrack.kind.
getVideoTracks() → JSArray<MediaStreamTrack>
The getVideoTracks() method of the MediaStream interface returns a sequence of MediaStreamTrack objects representing the video tracks in this stream.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeEventListener(String type, EventListener? callback, [JSAny options]) → void
The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.
inherited
removeTrack(MediaStreamTrack track) → void
The removeTrack() method of the MediaStream interface removes a MediaStreamTrack from a stream.
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
