hello!

I have a problem to use processing,
When i run it, the result is :
If you know the issue, thanks a lot !

Use surface.setTitle() instead of frame.setTitle in Processing 3
"Arial" is not available, so another font will be used. Use PFont.list() to show available fonts.
NullPointerException

Show your entire code

Sometimes it’s something small like loading before size()

Here the minimum of the code makes this mistake

// Librairies
import java.util.*;
import processing.video.*;
import jp.nyatla.nyar4psg.*;


// Déclaration des objets et des constantes
Capture cam;

// Déclaration des variables globales
String extcam = "/dev/video0";


PFont maPolice;
String[] cameras;



// Initialisations
void setup() 
{

    

  size(1280, 480,P3D); background(200); smooth(); //noLoop();
  
 
  cameras = Capture.list();
  
  if (cameras.length == 0) 

  {
    println("No camera"); 
    exit();
  } 
  else 
  {
    println("cameras:");
    for (int i = 0; i < cameras.length; i++) println(cameras[i]);
  }
  cam=new Capture(this,640,480,extcam); 
  cam.start();
}

// Programme principal
void draw()
{
  

 
  if (cam.available()) cam.read();
  cam.updatePixels(); image(cam,0,0);

  
}

any ideas?

thanks a lot !

What is this import? Are you using it in the provided minimal sketch above? If you remove it, does the error go away?

There are a few additional important details that you need to describe:

What is this other import in your sketch? Description, github link or library webpage? What is this library for? Removing the library resolves the problem?

Second, when you get the error, what line gets highlighted in the Processing editor?

What OS are you using?

The code you provided, beside the alien library, is a standard code available as an example in the PDE so it should work.
