Looking at the documentation of Qt5 it seems possible to change the pixel format of the camera. I need to create a QCameraViewfinderSettings
set the new pixel format and set the new settings to the camera... like in this example
QCameraViewfinderSettings viewfinderSettings;
viewfinderSettings.setPixelFormat(QVideoFrame::Format_RGB32);
camera->setViewfinderSettings(viewfinderSettings);
But I cannot find anything similar in QML... Is there any way to do the something in QML? I'd like something like:
Camera {
id: camera
viewfinder.pixelFormat = VideoFrame.Format_RGB32
}
If QML doesn't allow me to set the pixel format what alternatives have I?
No, you can't change the pixel format in QML per the maintainer of that component, but you can pass the QML object to C++ and do it from there per bug report 42909.
As Yoann Lopes wrote in that bug's comments, you can access the QCamera of the QML object with:
