    \class QMediaService

    \brief The QMediaService class provides a common base class for media

    service implementations.

    \ingroup multimedia

    \preliminary

    Media services provide implementations of the functionality promised

    by media objects, and allow multiple providers to implement a QMediaObject.

    To provide the functionality of a QMediaObject media services implement

    QMediaControl interfaces.  Services typically implement one core media

    control which provides the core feature of a media object, and some

    number of additional controls which provide either optional features of

    the media object, or features of a secondary media object or peripheral

    object.

    A pointer to media service's QMediaControl implementation can be obtained

    by passing the control's interface name to the requestControl() function.

    \code

    QMediaPlayerControl *control = qobject_cast<QMediaPlayerControl *>(

            service->requestControl("com.nokia.Qt.QMediaPlayerControl/1.0"));

    \endcode

    Media objects can use services loaded dynamically from plug-ins or

    implemented statically within an applications.  Plug-in based services

    should also implement the QMediaServiceProviderPlugin interface.  Static

    services should implement the QMediaServiceProvider interface.
