Why am I missing the Qt Multimedia functionality?

Question

I am new to Qt and I'm creating a simple application which will playback an audio file. I realized that I am lacking the Qt Multimedia API for audio when I wrote:

#include <QAudioOutput>

..and I get that there is no such file.

I downloaded the latest Qt SDK framework and I can't find a way to add these APIs. I am using Qt creator IDE.

IS there a way to get the multimedia functionality working maybe as an add-on or some other way?

Thanks.

Answer 1

Try including it like this:

#include <QtMultimedia/QAudioOutput>

Answer 2

Without more info it's hard to say, but possibly your include paths are just incomplete. Read https://doc.qt.io/archives/qt-4.7/qtmultimedia.html and be sure to add

QT += multimedia

to your project file.

Answer 3

try sudo apt-get install qtmultimedia5-dev
