So I've installed QtMultimedia and in the picture, you can see all the modules installed.

Then I added modules to my project's qmake

QT  = multimedia
QT  = multimediawidgets

And I can easily use stuff like QVideoWidget or QMediaPlayer and it compiles. But including QAbstractVideoSurface doesn't work!

#include <QAbstractVideoSurface>     //file not found

I've tried updating components and installing Qt 6.3.0, but the result is the same.

What module did I miss or maybe it's a bug?

CodePudding user response：

In Qt 6.0.0 and higher versions:

QAbstractVideoSurface has been replaced by the QVideoSink class, and generic rendering support has been enhanced to cover all pixel formats supported by Qt Multimedia.

please read Changes to Qt Multimedia.
