Detailed Description

The videoWidget() property of QVideoWidgetControl provides a pointer to a video widget implemented by the control's media service. This widget is owned by the media service and so care should be taken not to delete it.

QVideoWidgetControl is one of number of possible video output controls.

QVideoWidgetControl *widgetControl = mediaService->requestControl<QVideoWidgetControl *>();

layout->addWidget(widgetControl->videoWidget());

The interface name of QVideoWidgetControl is "com.copperspice.CS.videoWidgetControl/1.0" as defined in QVideoWidgetControl_iid.
