+/*!
+ \class QMediaService
+ \brief The QMediaService class provides a common base class for media
+ service implementations.
+ \ingroup multimedia-serv
+ \preliminary
+ \since 4.7
+
+ 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 control() function.
+
+ \code
+ QMediaPlayerControl *control = qobject_cast<QMediaPlayerControl *>(
+ service->control("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.
+
+ \sa QMediaObject, QMediaControl, QMediaServiceProvider, QMediaServiceProviderPlugin
