title: QMediaPlayer doesn't work in qt5
body: <p>I use Xcode 4.6 on Mac OS X 10.8 and Qt 5.1. I want to use QMeduaPlayer class in my application. Here is my code:</p>
  
  <pre><code>#include &lt;QApplication&gt;
  #include &lt;QMediaPlayer&gt;
  
  int main(int argc, char *argv[])
  {
      QApplication a(argc, argv);
      QMediaPlayer* pl = new QMediaPlayer();
      pl-&gt;setMedia(QUrl::fromLocalFile("Crashday.wav"));
      pl-&gt;play();
      a.exec();
  }
  </code></pre>
  
  <p>But it doesn’t work and in the console I see:</p>
