Get QAudioBuffer from QMediaPLayer

[azazaz]

Hi, I create stream player based on qmediaplayer and want add peak level meter to it.
i use functions from example recorder and make this:

my result left on image, on right what i need

peak level update based on signal from QAudioProbe

QAudioProbe *probe = new  QAudioProbe(); 
 connect(probe, SIGNAL(audioBufferProbed(QAudioBuffer)),
                 this, SLOT(processBuffer(QAudioBuffer)));

QAudioProbe *probe = new  QAudioProbe(); 
 connect(probe, SIGNAL(audioBufferProbed(QAudioBuffer)),
                 this, SLOT(processBuffer(QAudioBuffer)));

To copy to clipboard, switch view to plain text mode 

i tried emit this signal but it not working;

how to emit this signal or get audiobuffer from player for no use signal and send buffer to processBuffer manualy?

Have you called QAudioProbe::setSource() with your QMediaPlayer? (Almost exactly as in the documentation)
