Ok so I've just gotten started in processing and I'm working on a project with motion tracking. I was looking into OpenCV however I can't even seem to get the basics of the program started. My coding knowledge is limited but I'm hoping someone on here has had some experience with this.

I keep getting this error when I try to run the following code :

UnsatisfiedLinkError:hypermedia.video.OpenCV.capture(III)V

the red text is the line that is highlighted for the error. Any help is appreciated. Or if you can point me towards a "better" library that I can use for a draw program that draws with motion rather than the mouse. Cheers

1. import hypermedia.video.*;        //  Imports the OpenCV library
   OpenCV opencv;                    //  Creates a new OpenCV Object
    
   void setup()
   {
    
     size( 320, 240 );
    
     opencv = new OpenCV( this );    //  Initialises the OpenCV object
     opencv.capture( 320, 240 );     //  Opens a video capture stream
    
   }
    
   void draw()
   {
    
     opencv.read();                  //  Grabs a frame from the camera
     image( opencv.image(), 0, 0 );  //  Displays the image in the OpenCV buffer to the screen
    
   }
   

alright so I'm new to processing. I'm working on a project that is going to require some motion tracking or blob tracking. basically I have a drawing function just drawing text randomly using the mouse. what I want is to be able to use tracking to draw with my hand or body etc. In experience what is the best library available to do such a thing? here is the code I'm using. It's just a beginning sketch I'm using in order to figure out this tracking.

1. void setup() {
         size(1280, 480);
         background(0);
       }
   
       void draw() {
         if (mousePressed) {
           fill(0);
        
         } else{
           fill(random(255),random(255),random(255),(255));
           int cCode = int(random(97, 122));
           char c = char(cCode);
           text(c, mouseX, mouseY);
           textSize(60);
         }
       }
