QtMultimedia 5.0 not installed.



  • my error: module is not installed:
    i know my problem lies not on my qt creator because i can create video via a new qml. it lies on this old legacy code, i believe. any workaround?

    Hi,

    Maybe a silly question but do you have

    @QT += multimedia@

    in you pro file ?



  • QT += declarative
    QT += multimedia

    has been added to qmlapplicationviewer.pri & project file.
    error:
    module "QtMultimedia" is not installed" when i add import QtMultimedia 5.0 without any multimedia code. Is it because QmlApplicationViewer and multimedia not compatible

    What version of Qt (Qt version + compiler version) did you use to create the new QML project?

    What version of Qt (Qt version + compiler version) did you use to create your legacy code?

    Did "import QtMultimedia" ever work in your legacy code?
