Hello! how are you? I have a problem with the camera, I’m using macOS 10.15.6. I’m trying to run 2 codes, and I have the similar problem. For example:
```auto
import processing.video.*;
Capture video;
void setup () {
size (600,400);
video = new Capture(this,640,480,30);
video.start();
}
void draw () {
video.read();
background(0);
tint(255,mouseY,mouseY);
image (video,0,0,mouseX,mouseY);
}
```
The error is this:

Do the video example sketches work correctly?
Have you tried reinstalling the lib?
