[Interest] Creating a video feed or overlay

[Tom Isaacson]

I'm working on an app that reads data from a sensor then displays it on a graph using qwt. This part is working fine but what we want to do now is create a video feed of the graph that can be displayed in other apps. We'd also like to add the graph as an overlay to a video feed from a camera. Is either of these possible in Qt, and if so where do I start?

Thanks for any help,

Tom
