QMediaPlayer, saving frame

[aliks-os]

I want to save image of the frame. After reading of manuals, I have been understood, that I should to use QVideoProbe. I use the following code from manual

QMediaPlayer *player = new QMediaPlayer();
QVideoProbe *probe = new QVideoProbe;

connect(probe, SIGNAL(videoFrameProbed(QVideoFrame)), this, SLOT(processFrame(QVideoFrame)));

qDebug()<<probe->setSource(player); // Returns true, hopefully.

player->setVideoOutput(myVideoSurface);
player->setMedia(QUrl::fromLocalFile("observation.mp4"));
player->play(); // Start receving frames as they get presented to myVideoSurface

But I always have FALSE on probe->setSource(player);
so my slot processFrame is not triggered.

What I do wrong ?

Can any body point me to working example

Hi,

Depending on your platform, the probe might not be available.
