Getting Slow Motion Video while using QML Media Player-CodePudding

I have been trying to use QML MediaPlayer. So, I start testing the built-in example in Qt Creator (Media Player Example).

After doing some more tests with videos having fps more than 60 (e.g. 120 or 240 fps) I found a weird bug with the media player. The playing video becomes slow-motion! It looks like the fps is always considered 60 or maybe FPSs higher than 120 are not considered!

Note: I have tested with a built-in QML example that is using QML Media Player. Also I have tested with Qt6.3.4-Msvc2019-64Bit.

Any experience with this issue or any help will be appreciated.

Are You sure you have not set any playbackRate?

I have tried the to disable the vsync and it's better but not perfect.

QSurfaceFormat format;
    format.setProfile ( QSurfaceFormat::CoreProfile );
    format.setRenderableType ( QSurfaceFormat::OpenGLES );
    format.setSwapInterval ( 0 );
    format.setVersion ( 3, 0 );  
    QSurfaceFormat::setDefaultFormat ( format );
