Overview

This article shows how to play audio file using QMediaPlayer from Qt Mobility 1.1.

Project Configuration

Modify the project configuration .pro file by including Qt Mobility support:

CONFIG += mobility
MOBILITY+= multimedia

Source Code

  • .h

Include required headers:

#include <QMediaPlayer>

Declare slot and private members:

private slots:
 void statusChanged(QMediaPlayer::MediaStatus status);

private:

QMediaPlayer '''m_pPlayer;

.cpp

Play a file located on the device:

m_pPlayer = new QMediaPlayer(this);
connect(m_pPlayer, SIGNAL (positionChanged(qint64)), this, SLOT (statusChanged(qint64)));
//Select a file
m_pPlayer->setMedia(QUrl::fromLocalFile("e:SoundsDigitalGirl_Rules.mp3"));
//Set the volume
m_pPlayer->setVolume(50);
m_pPlayer->play();

Implement the declared slot: void MainWindow::statusChanged(QMediaPlayer::MediaStatus status) {

if ( (QMediaPlayer::LoadedMedia == status) && m_pPlayer)
{
m_pPlayer->play();
}

}
