QtMultimedia Qt Multimedia

Qt Multimedia is an essential module that provides a rich set of QML types and C++ classes to handle multimedia content. It also provides necessary APIs to access the camera and radio functionality. The included Qt Audio Engine provides types for 3D positional audio playback and management.

The Qt Multimedia Widgets module provides widget based multimedia classes.

The QML types can be imported into your applciation using the following import statement in your .qml file.

import QtMultimedia 5.4

If you intend to use the C++ classes in your application, include the C++ definitions using the following directive:

#include <QtMultimedia>

Note: If you are using a few classes from this module, we recommend including those specific classes only instead of the module.

To link against the corresponding C++ libraries, add the following to your qmake project file:

QT += multimedia
