java.lang.OutOfMemoryError

I have a lot of code.

To much to paste here.

When i run my sketch it goes fine but the memory is increasing till i get a memory leak.

Now my question is. How can i figure out where the problem is?

And is there anyone willing to look at my code?

It's for my graduation project which i have to finish in a few days.

Here is the red error text:

java(296,0xbb183000) malloc: *** mmap(size=528384) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug

Are you running in Java mode? I've seen a few issues on GitHub about memory management issues in Experimental mode, but if you're running in Java mode that's not the problem. You could use a tool like VisualVM (which comes with Java) to take a heap dump of your running sketch. A heap dump will show you all of the objects and how much memory they are using.

Looks like you have an issue with the usage of textures in OpenGL, but that's all I can say...

Or maybe the texture part requires more memory then the other parts (the leak for example) so that's why it stops with that error.

Anyway, i will look into it when i'm at home again.

I'm hoping it's not the blobscanner.

O yeah if i launch Java VisualVM.app, nothing starts up.

Is that normal?

When you launch VisualVM, you should get a window that looks something like this:

I just tested on my OS X 10.8 machine, and the built-in copy wouldn't run for me either. Luckily, you can download a standalone version from http://visualvm.java.net. I downloaded that and it worked perfectly.

Thanks. I don't really have time to figure out how it works but i will definitely do when i (failed) graduated.

I know where the bug is causes. And it's probably a processing bug (although every bug i posted so far was me doing something wrong).

I had this:

PGraphics preProcessedImage() {
if (updateReady() && tableBoundsValid()) {
preProcessed.loadPixels();
preProcessed.beginDraw();
preProcessed.background(0);
preProcessed.image(getImage().get(tableBounds.x1, tableBounds.y1, tableBounds.width(), tableBounds.height()), 0, 0);
preProcessed.image(maskImage, 0, 0, tableBounds.width(), tableBounds.height());
preProcessed.endDraw();
preProcessed.updatePixels();
if(preProcessed.width > 5) {
fastblur(preProcessed, 5);
}
return preProcessed;
}
return null;
}

Now i use this:

PImage preProcessedImage() {
if (updateReady() && tableBoundsValid()) {
tmp = getImage().get(tableBounds.x1, tableBounds.y1, tableBounds.width(), tableBounds.height());
if(preProcessed.width > 5) {
fastblur(tmp, 5);
}
return tmp;
}
return null;
}

And the memory is at a pretty stable 820 mb now.

Can you upload your code somewhere? I'm curious...

Re: java.lang.OutOfMemoryError

hmm i had it again. But it does make a huge difference. It's like 95% more stable now.

I'm uploading now, this can take some time since there are a lot of images included.

Here are the libraries you need:

(if you have no kinect it's no problem, it's lazy load and you can choose between webcam, kinect or images).

libraries:

https://code.google.com/p/simple-openni/

http://jklabs.net/maxlink/

http://keystonep5.sourceforge.net/

a modified version of blobscanner which contains a bugfix and a new method to scan with color.

https://dl.dropboxusercontent.com/u/17630770/Processing/libraries/blobscanner2%202.zip

Here is a old video which shows a bit what you have to do:

https://dl.dropboxusercontent.com/u/17630770/temp/circle_sequencer02.mov

I mostly use webcam now (not shown in the video).

For setting the colors to scan (adjust detector) make sure when you change the fuzziness slider that you click the color in the image again. I do this wrong in the video, you can see if i click base drum again the slider goes back to default 0.5. If i had clicked in the image it wouldn't have happened.

I use processing 201. The video library is used from processing 1.5.1 which is included in the code folder so no worries about that.

Would be really need if you can help me out.
