QT Problem

[majdbousaad]

I got this error:

could not load multimedia backend ""
QtMultimedia is not currently supported on this platform or compiler.
Failed to create QVideoSink "Not available"
Failed to initialize QMediaPlayer "Not available"

Before this I had a problem that we could not find qt "windows" in ""
I then put an enviroment variable called QT_QPA_PLATFORM_PLUGIN_PATH with the value "pyside6/plugins/platforms"

Hello, did it fix your issue?

Hello, I solved it by creating a venv enviroment.
But do you know what caused the problem outside the venv enviroment?

Probably a bad installation…

Did you try to make a clean install? Maybe take a look a pipx and install Manim Slides via pipx :)
