Functions

addRenderer

open override fun addRenderer(renderer: VideoSink)

Add a VideoSink that will receive frames.

dispose

open override fun dispose()

Disposes the track. LiveKit will generally take care of disposing tracks for you.

getRTCStats

suspend fun getRTCStats(): RTCStatsReport?

Return the RTCStatsReport for this track, or null if none is available.

fun getRTCStats(callback: RTCStatsCollectorCallback)

Calls the callback with the RTCStatsReport for this track, or null if none is available.

removeRenderer

open override fun removeRenderer(renderer: VideoSink)

Remove a previously added VideoSink.

restartTrack

fun restartTrack(options: LocalVideoTrackOptions = defaultsManager.videoTrackCaptureDefaults.copy())

Restart a track with new options.

setDeviceId

fun ~~setDeviceId~~(deviceId: String)

If this is a camera track, switches to the new camera determined by deviceId

start

open fun start()

Starts the track.

startCapture

open fun startCapture()

Starts the capturer with the capture params contained in options.

startForegroundService

suspend fun startForegroundService(notificationId: Int?, notification: Notification?)

A foreground service is generally required prior to startCapture for screen capture. This method starts up a helper foreground service that only serves to display a notification while capturing. This foreground service will automatically stop upon the end of screen capture.

stop

open override fun stop()

Stops the track.

stopCapture

open fun stopCapture()

Stops the capturer.

switchCamera

fun switchCamera(deviceId: String? = null, position: CameraPosition? = null)

Switch to a different camera. Only works if this track is backed by a camera capturer.
