    QVariant title = metaInfoResolver->metaData(QtMultimediaKit::Title);
    QVariant artist = metaInfoResolver->metaData(QtMultimediaKit::AlbumArtist);
    QVariant genre = metaInfoResolver->metaData(QtMultimediaKit::Genre);
    QVariant albumTitle = metaInfoResolver->metaData
(QtMultimediaKit::AlbumTitle);
    QVariant duration = metaInfoResolver->metaData
(QtMultimediaKit::Duration);//debugļ¼šduration invalid

QtMultimediaKit::Title,QtMultimediaKit::AlbumArtist,QtMultimediaKit::Genre
