Warning generated on calling the capture slot form QCamera

Kira

Hello All,

I am trying to run the below code :

 QByteArray cameraDevice;
    int cameraId = 1;
    QList<QByteArray> cameradev = QCamera::availableDevices();
    cameraDevice = cameradev[cameraId];

    QCamera *camera = new QCamera(cameraDevice);

    QString description = camera->deviceDescription(cameraDevice);
    qDebug()<<"Device Name"<< description;

    QCameraImageCapture *imageCapture = new QCameraImageCapture(camera);
    camera->setCaptureMode(QCamera::CaptureStillImage);
    camera->start();

    QImageEncoderSettings imageSettings;
    imageSettings.setCodec("image/jpeg");
    imageSettings.setResolution(1024,768);
    imageCapture->setEncodingSettings(imageSettings);

    imageCapture->setCaptureDestination(QCameraImageCapture::CaptureToBuffer);


//    Store image in buffer when captured
     QObject::connect(imageCapture, &QCameraImageCapture::imageCaptured, [=] (int id, QImage img) {

         img.save("samplerotated.jpeg","jpeg");


         QPoint center = img.rect().center();
         QMatrix matrix;
         matrix.translate(center.x(), center.y());
         matrix.rotate(-90);
         QImage dstImg = img.transformed(matrix);

         dstImg.save("New.jpeg","jpeg");

    });


    camera->searchAndLock();
    imageCapture->capture();
    camera->unlock();
    qDebug()<< camera->error();

The code works fine but sometimes generates the following warning.
QObject::moveToThread: Current thread (0x21d234e1db0) is not the object's thread (0x21d2ceeb370).
Cannot move to target thread (0x21d234e1db0)

How to resolve the following warning generated

Hi,

Are you calling moveToThread anywhere in your code ?
