Can't use webcam with higher resolutions

Hello, processers!

here I have this peculiar behaviour of my webcam (or pc) when trying to have a higher resolution web cam feed with these lines:

Capture cam;
import processing.video.*;
void setup() {
  //size(1280,960);
  fullScreen();
  cam = new Capture(this, 1280, 960, "FSC WebCam 130");
  cam.start();
  printArray(Capture.list());
}

void draw() {
  if (cam.available()) {
    cam.read();
  }

  image(cam, 0, 0, 1280, 1024);
}

black screen or single still frame appears when program is executed, upon closing it gives me this error: "(java.exe:4800): GStreamer-CRITICAL **: Trying to dispose element Video Capture, but it is in PAUSED instead of the NULL state. You need to explicitly set elements to the NULL state before dropping the final reference, to allow them to clean up. This problem may also be caused by a refcounting bug in the application or some element."

webcam used: fujitsu siemens ( http://mobilespecs.net/webcam/Fujitsu-Siemens/Fujitsu-Siemens_Webcam_130_portable.html )

If someone would have an idea how to solve it it would help immensely! Cheers!
