QMediaPlayer: positionChanged() Signal interrupts sound

[ChristianH]

Hello,

i am programming a software which includes playing a sound file.

Everytime when the signal positionChanged(qint64) is emitted, my position slider should update the current position of the sound file. This works fine, but everytime when this happens (every second) the sound interrupts for a moment.

In my class Soundfile i create a pointer of QMediaPlayer named soundfile.

QMediaPlayer* soundfile;

QMediaPlayer* soundfile;

To copy to clipboard, switch view to plain text mode 

In the constructor Soundfile() i wrote this:

soundfile = new QMediaPlayer(this, QMediaPlayer::LowLatency);
QObject::connect(soundfile, SIGNAL(positionChanged(qint64)), this, SLOT(changedPosition(qint64)));

soundfile = new QMediaPlayer(this, QMediaPlayer::LowLatency);
QObject::connect(soundfile, SIGNAL(positionChanged(qint64)), this, SLOT(changedPosition(qint64)));

To copy to clipboard, switch view to plain text mode 

The slot changedPosition in the class Soundfile is this:

void Soundfile::changedPosition(qint64 p) {

QTime time(0,0,0,0);
time = time.addMSecs(soundfile->position());
 
if(p != 0) recordSlider->setValue(p);
changeRecordTime(QString::number(p));
recordPositionLabel->setText("Current time: " + time.toString());
}

QTime time(0,0,0,0);
time = time.addMSecs(soundfile->position());

if(p != 0) recordSlider->setValue(p);
changeRecordTime(QString::number(p));
recordPositionLabel->setText("Current time: " + time.toString());
}

To copy to clipboard, switch view to plain text mode 

(the rest is updating the current time label)

Is there any problem why it could interrupting playing the sound file?

I hope someone has an idea.

With best regards,
Christian

Have you checked how long the slot needs to execute?
If it exceeds the time the player has buffered data for, then it can't play any further until the slot returns.
