playList->addMedia(QUrl::fromLocalFile("test2.mp3"));
testPlayer->setPlaylist(playList);
playList->setCurrentIndex(0);
qDebug() << "Test: " << testPlayer->metaData(QMediaMetaData::Title);
connect(testPlayer, SIGNAL(metaDataChanged()), this, SLOT(stc()));
stc();
void MainWindow::stc()
{
qDebug() << testPlayer->isMetaDataAvailable();
if(testPlayer->isMetaDataAvailable())
