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 ?

[houmingc]

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?
