[QtMultimedia] How to read metaData from all mediaObject in QMediaPlayList ?

superbobnoob

Hey. I read metaData in SLOT
@connect(&musicPlayer, SIGNAL(metaDataAvailableChanged(bool)), this, SLOT(updateInfo()));

void PlayerWindow::updateInfo()
{
QString author = musicPlayer.metaData("Author").toString();

QString title = musicPlayer.metaData("Title").toString();

qDebug() << author << " - " <&lt; title;

musicPlayList.next();

}@

and load files to playList
@void PlayerWindow::on_pushButton_clicked()
{
static QString path = QDir::homePath();
QStringList filePaths = QFileDialog::getOpenFileNames(this, tr("Open File"), path, tr("MP3 files (.mp3);;All files (.*)"));

if(!filePaths.empty())
{
    for(int i = 0; i&lt;filePaths.size(); i++)
    {
        musicPlayList.addMedia(QUrl::fromLocalFile&#40;filePaths[i]&#41;);
    }
    musicPlayList.setCurrentIndex(0);
}

}@

And this is too slow i think becouse it read metaData only for every second file.

So my question is how to do this right to get metaData of all files in QMediaPlayList
