    Default Get QAudioBuffer from QMediaPLayer

    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:
    http://gyazo.com/a45cb3f5dd5a072094d41463ad0b56c3.gif (the image is too large to insert it here, 183kb)


    my result left on image, on right what i need

    peak level update based on signal from QAudioProbe

    Qt Code:
    1. QAudioProbe *probe = new QAudioProbe();
    2. connect(probe, SIGNAL(audioBufferProbed(QAudioBuffer)),
    3. 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)
