Send audio voice via socket tcp. What signal.

zabitqt

Hey, I capture audio this time, but for the same reason of QAbstractVideoSurface.
I have successfull capture video end SEND PACKETS BYTES FRAME TO SOCKET TCP!!!
If someone want to know how I have done it send me a message DM.

Now this snippet capture audio but I want send data voice to socket channel tcp.
Iis there a signal for this purpose?

    QAudioRecorder* audioRecorder = new QAudioRecorder;

    QAudioEncoderSettings audioSettings;
    audioSettings.setCodec("audio/amr");
    audioSettings.setQuality(QMultimedia::HighQuality);

    audioRecorder->setEncodingSettings(audioSettings);

    //audioRecorder->setOutputLocation(QUrl(QCoreApplication::applicationDirPath() + "/" + "test_audio"));

    audioRecorder->record();

There's QAudioInput in Qt5 and QAudioSource in Qt6, with a example for both:
https://doc.qt.io/qt-5/qtmultimedia-multimedia-audioinput-example.html
https://doc.qt.io/qt-6/qtmultimedia-audiosource-example.html
Again what you captured from them are uncompressed raw audio.

QAudioRecorder* recorder = new QAudioRecorder();
    QAudioProbe* probe = new QAudioProbe;

    connect(probe, SIGNAL(audioBufferProbed(QAudioBuffer)), this, SLOT(processBuffer(QAudioBuffer)));
    

    QAudioEncoderSettings audioSettings;
    audioSettings.setCodec("audio/amr");
    audioSettings.setQuality(QMultimedia::HighQuality);

    recorder->setEncodingSettings(audioSettings);

    
    qDebug() << "probe ritorna " << probe->setSource(recorder); // Returns true, hopefully.


    recorder->record(); // Now we can do things like calculating levels or performing an FFT
    qDebug() << "scritto " << recorder->setOutputLocation(QCoreApplication::applicationDirPath() + "/" + "test_audio");
    myAudioServer = new MyAudioServer();
    myAudioServer->startServer();

    //qDebug() << o;
    qDebug() << recorder->supportedAudioCodecs();
    qDebug() << recorder->state();
    qDebug() << recorder->error();
    qDebug() << recorder->outputLocation();

SetOutLocation return false! Why?

FWIW, never use TCP to stream "realtime" multimedia data. Use UDP. Look at RTP/RTSP to see how it's done properly.

Ok It return false because I don't set QUrl string.
How can play WAV file? I have tried QSound::play but It crash in Thread.

Qt5Cored.pdb contains the debug information required to find the source for the module Qt5Cored.dll

void MyThreadAudioTcpSocket::run()
{
    qDebug() << "Audio Thread started";
    socket = new QTcpSocket();
    connect(socket, SIGNAL(readyRead()), this, SLOT(readyRead()), Qt::DirectConnection);
    connect(socket, SIGNAL(disconnected()), this, SLOT(disconnected()));
    socket->connectToHost("192.168.0.10", 12346);
    // we need to wait...
    if (!socket->waitForConnected(5000))
    {
        qDebug() << "Error: " << socket->errorString();
    }


    QSound bells("C:\\Users\\Administrator\\Documents\\test.wav");
    bells.play();

    exec();

}
