MediaStreamTrack extension type

The MediaStreamTrack interface of the Media Capture and Streams API represents a single media track within a stream; typically, these are audio or video tracks, but other track types may exist as well.

Some user agents subclass this interface to provide more precise information or functionality, such as CanvasCaptureMediaStreamTrack.

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
applyConstraints([MediaTrackConstraints constraints]) → JSPromise<JSAny?>
The applyConstraints() method of the MediaStreamTrack interface applies a set of constraints to the track; these constraints let the website or app establish ideal values and acceptable ranges of values for the constrainable properties of the track, such as frame rate, dimensions, echo cancellation, and so forth.
clone() → MediaStreamTrack
The clone() method of the MediaStreamTrack interface creates a duplicate of the MediaStreamTrack. This new MediaStreamTrack object is identical except for its unique MediaStreamTrack.id.
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
getCapabilities() → MediaTrackCapabilities
The getCapabilities() method of the MediaStreamTrack interface returns a MediaTrackCapabilities object which specifies the values or range of values which each constrainable property, based upon the platform and .
getConstraints() → MediaTrackConstraints
The getConstraints() method of the MediaStreamTrack interface returns a MediaTrackConstraints object containing the set of constraints most recently established for the track using a prior call to MediaStreamTrack.applyConstraints. These constraints indicate values and ranges of values that the website or application has specified are required or acceptable for the included constrainable properties.
getSettings() → MediaTrackSettings
The getSettings() method of the MediaStreamTrack interface returns a MediaTrackSettings object containing the current values of each of the constrainable properties for the current MediaStreamTrack.
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
stop() → void
The stop() method of the MediaStreamTrack interface stops the track.
toString() → String
A string representation of this object.

Operators

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