cameraCaptureState

Capture state of the camera device. Whenever the user grants a media-request sent by the web page, requesting video capture capabilities (navigator.mediaDevices.getUserMedia({video: true})) this property will be set to %WEBKIT_MEDIA_CAPTURE_STATE_ACTIVE.

The application can monitor this property and provide a visual indicator allowing to optionally deactivate or mute the capture device by setting this property respectively to %WEBKIT_MEDIA_CAPTURE_STATE_NONE or %WEBKIT_MEDIA_CAPTURE_STATE_MUTED.

If the capture state of the device is set to %WEBKIT_MEDIA_CAPTURE_STATE_NONE the web-page can still re-request the permission to the user. Permission desision caching is left to the application.
