| |
| \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 org.qt-project.qt.mediaplaylistsourcecontrol/5.0 as |
| defined in QMediaPlaylistSourceControl_iid. |
| |
| \sa QMediaService::requestControl(), QMediaPlayer |
