OpenCV not Working on Processing 3, on Ubuntu 18.04

[lub34]

Hey all, been running processing on my Jetson Nano on a Ubuntu 18.04 setup and everytime I try to run anything with the OpenCV library, I got this error. I installed the library directly through the PDE and have had no trouble with other libraries such as PixelPusher. The issue seems to be with capturing video, or video-based libraries in general such as Video and OpenCV. Curious if anyone has a solution?

Below, you will find, the code I'm running, a screenshot of the error I keep getting, and the best solution I've tried yet.

Code:
`
import processing.video.;
import java.awt.;

Capture video;

void setup() {
size(640, 480);
video = new Capture(this, 640/2, 480/2);

video.start();
}
`

Screenshot:

Best solution yet (yet still no success, merely changed the error to what I currently have now):
