public MediaCaptureState camera_capture_state { get; set; }
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.
