CanvasCaptureMediaStreamTrack extension type

The CanvasCaptureMediaStreamTrack interface of the Media Capture and Streams API represents the video track contained in a MediaStream being generated from a canvas following a call to HTMLCanvasElement.captureStream.

Properties

canvas → HTMLCanvasElement
The canvas read-only property of the CanvasCaptureMediaStreamTrack interface returns the HTMLCanvasElement from which frames are being captured.
no setter
contentHint ↔ String
The contentHint property of the MediaStreamTrack interface is a string that hints at the type of content the track contains. Allowable values depend on the value of the MediaStreamTrack.kind property.
getter/setter pairinherited
enabled ↔ bool
The enabled property of the MediaStreamTrack interface is a Boolean value which is true if the track is allowed to render the source stream or false if it is not. This can be used to intentionally mute a track.
getter/setter pairinherited
hashCode → int
The hash code for this object.
no setterinherited
id → String
The id read-only property of the MediaStreamTrack interface returns a string containing a unique identifier (GUID) for the track, which is generated by the .
no setterinherited
kind → String
The kind read-only property of the MediaStreamTrack interface returns a string set to "audio" if the track is an audio track and to "video" if it is a video track. It doesn't change if the track is disassociated from its source.
no setterinherited
label → String
The label read-only property of the MediaStreamTrack interface returns a string containing a -assigned label that identifies the track source, as in "internal microphone".
no setterinherited
muted → bool
The muted read-only property of the MediaStreamTrack interface returns a boolean value indicating whether or not the track is currently unable to provide media output.
no setterinherited
onended ↔ EventHandler?
getter/setter pairinherited
onmute ↔ EventHandler?
getter/setter pairinherited
onunmute ↔ EventHandler?
getter/setter pairinherited
readyState → MediaStreamTrackState
The readyState read-only property of the MediaStreamTrack interface returns an enumerated value giving the status of the track.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

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.
inherited
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.
inherited
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 .
inherited
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.
inherited
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.
inherited
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
requestFrame() → void
The requestFrame() method of the CanvasCaptureMediaStreamTrack interface requests that a frame be captured from the canvas and sent to the stream.
stop() → void
The stop() method of the MediaStreamTrack interface stops the track.
inherited
toString() → String
A string representation of this object.

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