Access denied finding property "vendor.camera.aux.packagelist"

@jsulm, no it is not being called. Seems like a bug?

    QMediaCaptureSession m_captureSession;
    QImageCapture *m_imageCapture = new QImageCapture;

    camera = new QCamera(QCameraDevice::FrontFace);
    m_captureSession.setCamera(camera);

    m_captureSession.setImageCapture(m_imageCapture);

    camera->start();

    if (!m_imageCapture->isReadyForCapture())
    {
        qDebug() << "Camera is not ready for capture";
    }

    QObject::connect(&btn, &QPushButton::clicked, [m_imageCapture, camera]()
                     {
                         qDebug() << camera->isActive() << " " << m_imageCapture->isReadyForCapture();
                         int id = m_imageCapture->captureToFile("/storage/emulated/0/Download/f.jpeg"); });

    QObject::connect(m_imageCapture, &QImageCapture::readyForCaptureChanged, []()
                     { qDebug() << "READYYYYYYYYYYYYYYYYYY"; });

There is no "READYYYYYYYYYYYYYYYYYY" in my logs. I have tried both on Xiaomi and Samsung.

@Ivelin What Qt version do you use? Try with the latest one.

[Ivelin]

@jsulm, I am using Qt 6.2.4.

I try to stick to something older, so there is lower chance for bugs, unfortunately this doesn't seem to be the case, so I will try the latest one.

Bugs get fixed in newer versions (of course new bugs are also introduced :-)).

@jsulm, hello

Late update. It is not the version I am pretty sure.

The Qt 6.2 example for camera works just fine, so it must be something from my code.

Yes, I am still banging my head, so I can fix that problem. it is been a week now I am getting pretty desperate

The problem must be in the code.

Could someone please help me ? Any Ideas ?

I also went over the whole documentation, but still can't see where is the problem in this simple code..

@Ivelin QMultimedia module was reworked in Qt6. Better to use the latest version of Qt6.

@JoeCFD, I am going to try With Qt 6.6 ( latest current ), but again the qt camera example for qt 6.2 worked just fine, so I suppose it should be a problem in the code.

@Ivelin put or zip your whole test code somewhere for other people to be able to access for testing.

[Ivelin]

@JoeCFD, I will, but I just think that I have found something !

This is my current code:

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    checkPermission();
    checkPermission1();

    QWidget widget;
    QPushButton btn;
    btn.setMinimumSize(QSize(200, 200));
    btn.setText("Take a picutre");

    QVBoxLayout layout;
    layout.addWidget(&btn);
    widget.setLayout(&layout);

    QCamera *camera = new QCamera;
    QMediaCaptureSession m_captureSession;
    QImageCapture *m_imageCapture;

    camera = new QCamera(QCameraDevice::FrontFace);
    m_captureSession.setCamera(camera);

    m_imageCapture = new QImageCapture;
    m_captureSession.setImageCapture(m_imageCapture);
    QObject::connect(camera, &QCamera::errorOccurred, [&camera]()
                     {
        if (camera->error() != QCamera::NoError)
            qDebug() << "ERROR: " << camera->errorString(); });

    QObject::connect(m_imageCapture, &QImageCapture::errorOccurred, [](int id, const QImageCapture::Error error, const QString &errorString)
                     { qDebug() << "ERROR: " << errorString; });

    camera->start();

    QObject::connect(&btn, &QPushButton::clicked, [m_imageCapture, camera]()
                     {
                         qDebug() << camera->isActive() << " " << m_imageCapture->isReadyForCapture();
                         int id = m_imageCapture->captureToFile("/storage/emulated/0/Download/f.jpeg"); });

    widget.show();
    return a.exec();
}

After having those QObject:connect for rrorOccured when clicking the button, so I can take a picture I get:

ERROR:  "Could not capture in stopped state"

Maybe this is a valid lead ?

Could someone take a look?
