I would make a script in Python including the OpenCV library or similar and for example putting a video on full screen continously playing and putting other stuff on it.
Is it possible to include whatever Python library I want and include a playable video on a separate “layer” creating two layers, one above the other? Does EYESY make this available?
You can import libraries to the EYESY. Section 6.3 of the manual might be useful for this.
The EYESY ships with an OS that uses Pygame library to generate the visuals. If you have questions about Pygame’s visual capabilities, please see the Pygame Documentation.
