QML camera feed is reversed

b15h0y

Hello, I just started developing a simple image processing app with qml and python and had question regarding setting up the camera feed.

My Main.qml file currently has:

import QtQuick 2.7
import QtMultimedia 5.4
import Ubuntu.Components 1.3
import QtQuick.Layouts 1.3
import Qt.labs.settings 1.0
import io.thp.pyotherside 1.3

MainView {
    id: root
    objectName: 'mainView'
    applicationName: 'example-hello.none'
    automaticOrientation: true
    width: units.gu(45)
    height: units.gu(75)

    Page {
        id:main
        anchors.fill: parent
        width: 640
        height: 360

        header: PageHeader {
        id: header
        title: i18n.tr('Camera')
        }

        Camera {
            id: camera
            imageProcessing.whiteBalanceMode: CameraImageProcessing.WhiteBalanceFlash
            exposure {
                exposureCompensation: -1.0
                exposureMode: Camera.ExposurePortrait
            }
            flash.mode: Camera.FlashRedEyeReduction
            imageCapture {
                onImageCaptured: {
                    photoPreview.source = preview  // Show the preview in an Image
                }
            }
            transform: Rotation { origin.x: 25; origin.y: 25; angle: 45}

        }

        VideoOutput {
            source: camera
            anchors.fill: parent
            focus : visible // to receive focus and capture key events when visible
        }

        Image {
            id: photoPreview
        }
        
    }

//declare a variable to import a Python module
    Python {
        id: python

        //connect main.py
        Component.onCompleted: {
            addImportPath(Qt.resolvedUrl('../src/'));
            importModule_sync("main")
        }

        onError: {
            console.log('python error: ' + traceback);
        }          
    }
}

Camera is working but the view is flipped, I tried using a Transform to rotate it but the app crashes, what am I missing here? also is it possible to send the camera feed in real time to a python function in my main.py file that I linked at the end?

Testing device : Volla Phone
note: normal camera app is working properly, so the issue is code related
