    \brief The QMediaControl class provides a base interface for media service controls.

    Media controls provide an interface to individual features provided by a
    media service.  Most services implement a principal control which exposes
    the core functionality of the service and a number of optional controls which
    expose any additional functionality.

    A pointer to a control implemented by a media service can be obtained using
    the \l {QMediaService::requestControl()} member of QMediaService.  If the
    service doesn't implement a control it will instead return a null pointer.

    \snippet multimedia-snippets/media.cpp Request control

    Alternatively if the IId of the control has been declared using
    Q_MEDIA_DECLARE_CONTROL the template version of
    QMediaService::requestControl() can be used to request the service without
    explicitly passing the IId or using qobject_cast().

    \snippet multimedia-snippets/media.cpp Request control templated

    Most application code will not interface directly with a media service's
    controls, instead the QMediaObject which owns the service acts as an
    intermediary between one or more controls and the application.

/*!
    \macro Q_MEDIA_DECLARE_CONTROL(Class, IId)
    \relates QMediaControl

    The Q_MEDIA_DECLARE_CONTROL macro declares an \a IId for a \a Class that
    inherits from QMediaControl.

    Declaring an IId for a QMediaControl allows an instance of that control to
    be requested from QMediaService::requestControl() without explicitly
    passing the IId.
