[PyQt] QML QtMultimedia Bug(?) on Ubuntu

Hi Phil,


A colleague of mine is trying to use the QtQuick Multimedia module (import QtMultimedia 5.6) on Ubuntu having installed PyQt5 via pip. The application fails on this import complaining that libQt5MultimediaQuick_p.so cannot be found and, sure enough, it doesn’t seem to be there. We’ve tried upgrading via ‘pip install –U pyqt5’ with no change/improvement. Any suggestions? The basic example is as follows:


import QtQuick 2.6

import QtMultimedia 5.6


Item {

    width: 640

    height: 360


    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





    VideoOutput {

        source: camera

        anchors.fill: parent

        focus : visible // to receive focus and capture key events when visible



    Image {

        id: photoPreview




Cheers, Rob
