if you have a new setup the

- video

AND

- GLvideo

( both from contribution manager ) not work anymore.

pls. load the new video lib as i link above.

if you have a older system ( as the raspbian zip i used above )  
GLvideo works for the capture but for the  
video need a repair, i did by a own build might read [here](http://kll.engineering-news.org/kllfusion01/articles.php?article_id=160)

but best is just do a new setup / new processing install /  
and video lib from  
[https://github.com/processing/processing-video/releases](https://github.com/processing/processing-video/releases) ,

all only tested on RPI3B+ hardware
