Detailed DescriptionThe 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 com.nokia.Qt.QMediaPlaylistSourceControl/1.0 as defined in QMediaPlaylistSourceControl_iid. See also QMediaService::requestControl() and QMediaPlayer. Member Function Documentation
