Modifier and Type	Method and Description
Promise<JsArray<MediaDeviceInfo>>	enumerateDevices() The MediaDevices method enumerateDevices() requests a list of the available media input and output devices, such as microphones, cameras, headsets, and so forth.
Promise<MediaStream>	getDisplayMedia() The MediaDevices interface's getDisplayMedia() method prompts the user to select and grant permission to capture the contents of a display or portion thereof (such as a window) as a MediaStream.
Promise<MediaStream>	getDisplayMedia(DisplayMediaStreamConstraints constraints) The MediaDevices interface's getDisplayMedia() method prompts the user to select and grant permission to capture the contents of a display or portion thereof (such as a window) as a MediaStream.
MediaTrackSupportedConstraints	getSupportedConstraints() The getSupportedConstraints() method of the MediaDevices interface returns an object based on the MediaTrackSupportedConstraints dictionary, whose member fields each specify one of the constrainable properties the user agent understands.
Promise<MediaStream>	getUserMedia() The MediaDevices.getUserMedia() method prompts the user for permission to use a media input which produces a MediaStream with tracks containing the requested types of media.
Promise<MediaStream>	getUserMedia(MediaStreamConstraints constraints) The MediaDevices.getUserMedia() method prompts the user for permission to use a media input which produces a MediaStream with tracks containing the requested types of media.

Field Detail

ondevicechange

@Nullable
public EventHandler ondevicechange

The MediaDevices.ondevicechange property is an EventHandler which specifies a function to be called when the devicechange event occurs on a MediaDevices instance. This happens whenever the set of media devices available to the user agent and, by extension, to the web site or app has changed. You can at any time use enumerateDevices() to get the updated list of available devices.
