The QMediaPlayer
class is a high level media playback class. It can be used to playback audio of video media files. The content to playback is specified as a QUrl
object.
player = QMediaPlayer() audioOutput = QAudioOutput() player.setAudioOutput(audioOutput) connect(player, SIGNAL(positionChanged(qint64)), self, SLOT(positionChanged(qint64))) player.setSource(QUrl.fromLocalFile("/Users/me/Music/coolsong.mp3")) audioOutput.setVolume(50) player.play()
QVideoWidget
can be used with QMediaPlayer
for video rendering.
