[Interest] Simplest way of dynamically updating a texture to be displayed on a shader material

I have a material that is painting a texture. The texture was created with window()->createTextureFromImage
Let’s say that now I want to update that image at 60 frames per second. This might not be a very efficient way of doing it.
What would be the simplest way of creating a texture which will constantly be updated and painted via QSGMaterialShader
I’ve seen that there is a private QSGVideoNode_* that basically paints a video frame using a texture that is updated whenever a new frame arrives.
Would this be the best example (and the most performant way) for what I am trying to achieve?
