    \class QVideoRendererControl
    \preliminary

    \brief The QVideoRendererControl class provides a control for rendering
    to a video surface.

    \ingroup multimedia-serv

    Using the surface() property of QVideoRendererControl a QAbstractVideoSurface
    may be set as the video render target of a QMediaService.

    \code
    QVideoRendererControl *rendererControl = mediaService->control<QVideoRendererControl *>();
    rendererControl->setSurface(myVideoSurface);
    \endcode

    QVideoRendererControl is one of number of possible video output controls,
    in order to receive video it must be made the active video output
    control by setting the output property of QVideoOutputControl to
    \l {QVideoOutputControl::RendererOutput}{RendererOutput}. Consequently any
    QMediaService that implements QVideoRendererControl must also implement
    QVideoOutputControl.

    \code
    QVideoOutputControl *outputControl = mediaService->control<QVideoOutputControl *>();
    outputControl->setOutput(QVideoOutputControl::RendererOutput);
    \endcode

    The interface name of QVideoRendererControl is \c com.nokia.Qt.QVideoRendererControl/1.0 as
    defined in QVideoRendererControl_iid.

    \sa QMediaService::control(), QVideoOutputControl, QVideoWidget
