\brief The QMediaPlaylist class provides a list of media content to play.
QMediaPlaylist is intended to be used with other media objects,
like QMediaPlayer.
QMediaPlaylist allows to access the service intrinsic playlist functionality
if available, otherwise it provides the local memory playlist implementation.
\snippet multimedia-snippets/media.cpp Movie playlist
Depending on playlist source implementation, most of the playlist mutating
operations can be asynchronous.
QMediaPlayList currently supports M3U playlists (file extension .m3u and .m3u8).

The QMediaPlaylist::PlaybackMode describes the order items in playlist are played.
\value CurrentItemOnce The current item is played only once.
\value CurrentItemInLoop The current item is played repeatedly in a loop.
\value Sequential Playback starts from the current and moves through each successive item until the last is reached and then stops.
The next item is a null item when the last one is currently playing.
\value Loop Playback restarts at the first item after the last has finished playing.
