video capture / eclipse
Mar 8th, 2008, 6:42am  
The following program works fine using the Processing IDE, but I only get a blank screen when I try to run it in Eclipse. No errors, just blankness... captureEvent() never gets called... the window is sized correctly but the background color doesn't change.

Any ideas? I'm on an intel powerbook running Leopard... thanks for any help! - Charlie

   camera.read();

 public void draw() {
   background(0);
   image(camera,0,0);
 }

I found this thread which seems relevant:

http://processing.org/discourse/yabb_beta/YaBB.cgi?board=Video;action=display;num=1203252042

It recommends setting the maximum heap size of the virtual machine to lower than 500MB; the poster couldn't figure out how to get it to work at higher settings. Unfortunately, setting it lower than 500 MB didn't help me...

OK, I noticed early today that I had two processes that had hung on my computer:

CompressorJobController
CompressorTranscoder

If I quit these using the Activity Monitor or plain old kill then the applet launched via Eclipse will show the camera feed once or twice. Then the same two processes hang and I have to force quit all over again to get things working.

Any idea what the problem might be or why the Processing IDE doesn't have these issues?

So far it seems to work consistently in NetBeans... I guess I will use that instead of Eclipse.
