+    \class QMediaPlaylistSourceControl
+    \ingroup multimedia
+
+    \preliminary
+    \brief The QMediaPlaylistSourceControl class provides access to the playlist playback
+    functionality of a QMediaService.
+
+    This control allows QMediaPlaylist to be passed directly to the service
+    instead of playing media sources one by one.  This control should be
+    implemented if backend benefits from knowing the next media source to be
+    played, for example for preloading, cross fading or gap-less playback.
+
+    If QMediaPlaylistSourceControl is provided, the backend must listen for
+    current playlist item changes to load corresponding media source and
+    advance the playlist  with QMediaPlaylist::next() when playback of the
+    current media is finished.
+
+    The interface name of QMediaPlaylistSourceControl is \c com.nokia.Qt.QMediaPlaylistSourceControl/1.0 as
+    defined in QMediaPlaylistSourceControl_iid.
+
+    \sa QMediaService::requestControl(), QMediaPlayer
