QMediaPlayer using problem



  • Hi, I use Xcode 4.6 on Mac OS X 10.8 and Qt 5.1. I want to use QMediaPlayer class in my application. Here is my code:
    @
    #include <QApplication>
    #include <QMediaPlayer>

    int main(int argc, char argv[])
    {
    QApplication a(argc, argv);
    QMediaPlayer
    pl = new QMediaPlayer();
    pl->setMedia(QUrl::fromLocalFile("Crashday.wav"));
    pl->play();
    a.exec();
    }
    @

    But it doesn't work and in console I see:
