Capture works in Processing IDE but not in Eclipse

in Integration and Hardware • 2 years ago

Heres the code:

package schalterraum;
import processing.core.PApplet;
import processing.video.*;
public class PhotoStage
{
private Capture myCapture;
private PApplet parent;
public PhotoStage(PApplet p)
{
parent = p;
init();
}
private void init()
{
myCapture = new Capture(parent, 620, 480, 30);
}
public void draw()
{
parent.image(myCapture, 0, 0);
}
public void captureEvent(Capture myCapture)
{
myCapture.read();
}
}

The error

If I'm adressing a capture device directly (Capture.list()[0]) the error changes to this

Quicktime 7 is installed and in the System Libaray (QTJava.zip). Also tried adding QTJava from processing folder to build path, didnt change anything.

Also starting application in 32bit mode, java version "1.6.0_26".

Getting mad here ..

Could you ever get this to work? I'm working on something similar, capture from an acquisition card.
It works in processing, but not in eclipse. Getting mad here, too...

Re: Capture works in Processing IDE but not in Eclipse

i'm not sure, cause sometime during the project i had to change from my mac to windows as the final system where the program would run. unfortunately right now i dont have eclipse installed on my mac, so i cant test the code properly.

but i browsed the final code and the only main difference i found was how i outputted the capture.

this:

parent.image(myCapture, 0, 0);

changed to:

beginShape(QUADS);
texture(webcam);
vertex(0, 0, webcam.width, 0);
vertex(image_width, 0, 0, 0);
vertex(image_width, image_height , 0, webcam.height);
vertex(0, image_height, webcam.width, webcam.height);
endShape();

maybe that helps? let me know. otherwise i'll install eclipse and see if i can get it running.

Re: Capture works in Processing IDE but not in Eclipse

my code is running now. and its also running without the bugfix i posted a few minutes ago. but i have to say that i'm running on a different system today. back then it probably was mac os 10.5 or 10.6. now i'm running a clean install of 10.8, and a different version of eclipse and quicktime .. many factors changed.

what system are running this on? have you tried a different capture source? maybe i can run the code and see if it works .. ?

I'm running 10.8. I changed to 32bits, as I saw that was the problem. I can now list the Capture devices.
Most curiously, eclipse can't find the cam.start() function......

I need to head home right now, it's running pretty late here, but i'll be on this tmrw again. I need it(among other things) running by friday, so i'll defo be on it.. . ^^

Thanks for your answers, hopefully i fin a fix and post it here, otherwise I will greatly appreciate your help!

PS:
I was running processing 2.0, just dl'ed 1.5 again, will install and test first thing in the morning.
