Video not visible when using QtQuick3D

LeBeef

Hello Folks,

I have trouble using QtQuick3D and Video from QtMultimedia together. When I activate QtQuick3D the video is not visible anymore. I am using Pyside2 5.15.1 on Mac OS 10.14.6

Does anyone know how to solve this problem? The problem occurs as soon as I set surface format on app start like:

fmt = QSurfaceFormat()
fmt.setDepthBufferSize(24)
fmt.setSamples(4)
fmt.setStencilBufferSize(8)
fmt.setVersion(4, 3)
fmt.setProfile(QSurfaceFormat.CoreProfile)
QSurfaceFormat.setDefaultFormat(fmt)

When I remove these lines, the video works fine, but then I can not use View3D anymore.

Here is the missing qml part:

import QtQuick 2.15
import QtQuick3D 1.15
import QtQuick3D.Helpers 1.15
import QtMultimedia 5.15

Item {
    id: root_component
    anchors.fill: parent

    Video {
        anchors.fill: parent
        source: "assets/01_Animation_PTB.mp4"
        Component.onCompleted: {
            play()
        }
    }

    Item {
//        anchors.fill: parent
        width: 300
        height: 200

        View3D {
            id: view
            anchors.fill: parent

            environment: SceneEnvironment {
                clearColor: "skyblue"
                backgroundMode: SceneEnvironment.Color
            }

            PerspectiveCamera {
                position: Qt.vector3d(0, 200, 300)
                eulerRotation.x: -30
            }

            DirectionalLight {
                eulerRotation.x: -30
                eulerRotation.y: -70
            }

            Model {
                position: Qt.vector3d(0, 150, 0)
                source: "#Sphere"

                materials: [
                    DefaultMaterial {

                        }
                    }
                ]

                SequentialAnimation on y {
                    loops: Animation.Infinite
                    NumberAnimation {
                        duration: 3000
                        to: -150
                        from: 150
                        easing.type:Easing.InQuad
                    }
                    NumberAnimation {
                        duration: 3000
                        to: 150
                        from: -150
                        easing.type:Easing.OutQuad
                    }
                }
            }
        }
    }
}
