DeviceController

interface DeviceController

DeviceController keeps track of the devices being used for audio device (e.g. built-in speaker), video input (e.g. camera)). The list functions return MediaDevice objects. Changes in device availability are broadcast to any registered DeviceChangeObserver.

Functions

addDeviceChangeObserver

Adds an observer to receive callbacks about device changes.

abstract fun addDeviceChangeObserver(observer: DeviceChangeObserver): Unit

chooseAudioDevice

Selects an audio device to use.

abstract fun chooseAudioDevice(mediaDevice: MediaDevice): Unit

getActiveAudioDevice

Get the active input/output audio device in the meeting, return null if there isn't any.

abstract fun getActiveAudioDevice(): MediaDevice?

getActiveCamera

Get the currently active camera, if any. This will return null if using a custom source, e.g. one passed in via AudioVideoControllerFacade.startLocalVideo

abstract fun getActiveCamera(): MediaDevice?

listAudioDevices

Lists currently available audio devices.

abstract fun listAudioDevices(): List<MediaDevice>

removeDeviceChangeObserver

Removes an observer to stop receiving callbacks about device changes.

abstract fun removeDeviceChangeObserver(observer: DeviceChangeObserver): Unit

switchCamera

Switches the currently active camera. This will no-op if using a custom source, e.g. one passed in via AudioVideoControllerFacade.startLocalVideo

abstract fun switchCamera(): Unit
