Recording audio stream

[c1223]

I want to use QT to record an internet audio stream. So far I can play the stream:

player = new QMediaPlayer();
    //connect(player, SIGNAL(positionChanged(qint64)), this, SLOT(positionChanged(qint64)));
    player->setMedia(QUrl("http://idobiradio.idobi.com/;stream.mp3"));
    player->setVolume(50);
    player->play();

player = new QMediaPlayer();
    //connect(player, SIGNAL(positionChanged(qint64)), this, SLOT(positionChanged(qint64)));
    player->setMedia(QUrl("http://idobiradio.idobi.com/;stream.mp3"));
    player->setVolume(50);
    player->play();

To copy to clipboard, switch view to plain text mode 

However, I want to take that data and record it to an MP3. How would I do that? I've been looking at using QIODevice but can't quite work out how to extract the data stream from the media player.

Thanks
