Play Audio File Using Qt Mobility

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();
}

}
