Field Detail

ondevicechange

public @JsNullable 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.

Method Detail

enumerateDevices

public @JsNonNull 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.

MediaDevices.enumerateDevices - MDN, mediaDevices: enumerateDevices - Media Capture and Streams

getSupportedConstraints

public @JsNonNull 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.

getUserMedia

public @JsNonNull Promise<MediaStream> getUserMedia(@Nonnull
                                                    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.

See Also:

MediaDevices.getUserMedia - MDN, MediaDevices.getUserMedia() - Media Capture and Streams

getUserMedia

public @JsNonNull 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.

getDisplayMedia

public @JsNonNull Promise<MediaStream> getDisplayMedia(@Nonnull
                                                       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.

See Also:

MediaDevices.getDisplayMedia - MDN, MediaDevices.getDisplayMedia() - Screen Capture

getDisplayMedia

public @JsNonNull Promise<MediaStream> getDisplayMedia()
