I tried to display the video stream from a camera in real-time with PySide6, and it worked well by implementing a subclass of QQuickImageProvider. However, someone mentioned that QQuickImageProvider is a bit complicated, QQuickPaintedItem could be a good alternative which may bring performance improvements, higher customizability, and the ability to implement more features.

Since he was talking based on the context of C++, I've been searching the web for several days. Sadly, there weren't too many results related to implementing QQuickPaintedItem within a PySide/QML project, not to mentions comparison between them.

So here is the quetion from a rookie: Is QQuickPaintedItem really a better option? How about the implement? Can you provide some examples?

Thanks.
