Hi!
I get 10-30 images from server. If i show in android phone images in QML Image, then image flicked when updating. How convert QImages in video and show in qml?

Hi,

That something that would be simpler to do server side.

Server can retur me only images. I create class

class ImageProvider : public QQuickImageProvider
{
public:
    ImageProvider() : QQuickImageProvider(QQuickImageProvider::Pixmap)
    {
    }
 
    QPixmap m_pixmap = QPixmap("/home/owner/Загрузки/image_2022-02-04_15-52-48.png");
 
    QPixmap requestPixmap(const QString &id, QSize *size, const QSize &requestedSize) override
    {
        return m_pixmap;
    }
};

and set in main.cpp

engine.addImageProvider(QLatin1String("imageProviderIRImage"),  appCore->m_imageProviderIRImage);

And set source image in qml

source: "image://imageProviderIRImage"

But image no updating whin I update m_pixmap? Function requestPixmap used only once. How I can update image in QML?

Why should image be reloaded with this code?
The image in loaded once by ImageProvider and in QML the link is static, so once image is loaded there is no reason to request image again.

It is help me. I change source when updating image.

            imageIrImage.source = "image://imageProviderIRImage"
            imageIrImage.source = "image://imageProviderIRImage/ir"
