Hi GWAK,  
i don’t know library for this, i will go for glsl filter…  
but, more easily, you can process each pixels, get the color, if it is “green” replace by a color or same pixel from another image,  
like [here](https://forum.processing.org/two/discussion/25647/greenscreen-effect-for-movie.html) for movie frames

i found too this in the forum: [key-out-color-from-video](https://discourse.processing.org/t/key-out-color-from-video/324)  
i hope it help…
