Open file containing playlist with QFile and then read/write it with QTextStream or QDataStream. Smth like this:

// Reading
QFile f("list.pl");
if (f.open(QFile::ReadOnly)) {
  QDataStream s(&f);
  QString song;
  while (!s.atEnd()) { s >> song; }
}

You can extend QDataStream for reading/writing your custom data (http://doc.qt.io/qt-5/qdatastream.html)

#include <QMediaPlaylist>
#include <QFileDialog>
#include <QDebug>
void MainWindow::on_pushButton_released()
{
QMediaPlaylist* playlist = new QMediaPlaylist;
playlist->addMedia(QUrl("http://example.com/movie1.mp4"));
playlist->addMedia(QUrl("http://example.com/movie2.mp4"));
playlist->addMedia(QUrl("http://example.com/movie3.mp4"));
QString fn=QFileDialog::getSaveFileName(this,"Save file",QDir::currentPath(),
"Text files (.txt);;All files (.*)");
qDebug() << playlist->save(QUrl::fromLocalFile(fn),"m3u");
delete QMediaPlaylist;
}
