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

@povoq oh, I am sorry, I was trying to start developing with QML and python and thought clickable should be on the phone.

I'm trying to get clickable and docker running on my UT phone (Volla phone), however starting the services with sudo systemctl start docker yields the following error:

Failed to start docker.service: Unknown unit: docker.service
See system logs and 'systemctl status docker.service' for details.

Checking systemctl status docker.service gives:

Failed to get properties: No such interface ''

Info about UT:

Distributor ID: Ubuntu
Description:    Ubuntu 16.04.7 LTS
Release:    16.04
Codename:   xenial

Any idea about a solution to this, haven't found something useful online
