I am looking for the simplest way to do alpha fading between two video channels and control it with physical buttons.
I have tested the videos with OMXPlayer, and they are good (both on codec, resolution, file size, duration, fps, etc.), but I don't know how to make the fade between two videos.
How can I do it?
there are some different ways to do it. I have actually tried with gstreamer wrapper (the one in openframeworks) but it is super slow and does not keep the right framerate. So I need a solution tailored to rasberrypi.
