loadPixels() with Capture failing on 3.0 and 3.0.1

[MAKIO135]

Stil failing with Processing 3.1.1 on Windows 8.1

May be related but displaying cam inside a PGraphics also fails in P2D:

import processing.video.*;

Capture video;
PGraphics pg;

void setup() {
    size(320, 240, P2D);

    video = new Capture(this, width, height);
    video.start(); 

    pg = createGraphics(width, height);
    pg.beginDraw();
    pg.background(255, 0, 0);
    pg.endDraw();
}

void draw() {
    if (video.available()) {
        video.read();
        pg.beginDraw();
        pg.image(video, 0, 0);
        pg.endDraw();
    }

    image( pg, 0, 0);
}

Still an issue. Maybe some changes to the list method. With cameras[1] the smallest available resolution, it works again.

Tested on Windows 10 Processing 3.3.3

import processing.video.*;

Capture cam;

void setup() {
  size(640, 480, P2D);
  String[] cameras = Capture.list();
  cam = new Capture(this, cameras[1]);
  cam.start();
}

void draw() {
  if (cam.available() == true) {
    cam.read();
  }
  image(cam, 0, 0, width, height);
  cam.loadPixels();
}

@shiffman Yes, calling loadPixels() with the OpenGL renderer slows down the sketch because image data needs to be copied from GPU memory, so it is not recommended, specially for large resolutions,
