\brief The QMediaBackgroundPlaybackControl class provides access to the background playback
related control of a QMediaService.
If a QMediaService can play media in background, it should implement QMediaBackgroundPlaybackControl.
This control provides a means to set the \l {setContextId()}{contextId} for application,
\l {acquire()}{acquire the resource for playback} and \l {release()} {release the playback resource}.
The interface name of QMediaBackgroundPlaybackControl is \c com.nokia.Qt.QMediaBackgroundPlaybackControl/1.0 as
defined in QMediaBackgroundPlaybackControl_iid.
