Hi
I try to get the meta data of music file (i try different files and udio formats mp3 wav etc) all files are good becaouse other players shows meta data :C
I try it on different ways but no one method work :/
my code:
Qt Code: 
  1. testPlayer = new QMediaPlayer;
  2.     playList = new QMediaPlaylist;
  3.  
  4.     testPlayer->setVolume(50);
  5. // testPlayer->setMedia(QUrl::fromLocalFile("test2.mp3")); // try without playlist -> dont work :C
  6.     playList->addMedia(QUrl::fromLocalFile("test2.mp3"));
  7.     testPlayer->setPlaylist(playList);
  8.     playList->setCurrentIndex(0);
  9.     qDebug() << "Test: " << testPlayer->metaData(QMediaMetaData::Title);
  10.  
  11.     connect(testPlayer, SIGNAL(metaDataChanged()), this, SLOT(stc()));
  12.  
  13.     stc();
To copy to clipboard, switch view to plain text mode 

Qt Code: 
  1. void MainWindow::stc()
  2. {
  3.     qDebug() << testPlayer->isMetaDataAvailable();
  4.     if(testPlayer->isMetaDataAvailable())
  5.     {
  6.         qDebug() << testPlayer->metaData(QMediaMetaData::Duration);
  7.     }
  8. }
To copy to clipboard, switch view to plain text mode 

and i always get result data
Test: QVariant(Invalid)
false
false
false
false
what i do wrong :C ?
