\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.
|
|
|
|
