is it possible to using dsj for capture video within the processing? here's the link http://www.humatic.de/htools/dsj.htm,

i tried,but no idea how to do it in processing,like those,the capture device is working however there's no video images in the rendering window

import de.humatic.dsj.*;
int CAPTURE_DEVICE = 0,IMAGE_HEIGHT,IMAGE_WIDTH;
DSCapture graph;


void setup(){
  size(800,600);

  DSEnvironment.unlockDLL("xxxx", -232504, 1811073, 0);
  DSFilterInfo[][] dsi = DSCapture.queryDevices();
  graph = new DSCapture(0, dsi[CAPTURE_DEVICE][0], true, null, null);

  graph.setPreview();
 
}

void draw(){
 
}

thanks in advanced!

Interesting library, at least for Windows users...
I don't have capture device, so I can't try your code.
You don't tell us which system you use (I see warnings for Vista) nor which Processing version you have (I assume 1.0, right?).

Is setPreview() supposed to spawn a preview window? Otherwise I don't see how Processing would deal with the DSJ data.

Also I see in DSJ's DSCapture reference "setPreview(): Reset the graph into preview mode after a capture file had been set."
I don't see this capture file setting. I don't know if it is mandatory, though.

Mmm, my Japanese is a bit rusty (TBH, it never reached the skill to read such page without help!). What does it says? I understand the "Processing library", but beyond that...

I see there is a link to a CaptureDS.zip

OK, so it is a good opportunity to use Google's linguistic tools. Translation is funny:

Library Processing

On this page, Processing and for small public libraries.

CaptureDS

Processing of library Capture, QuickTime for Java using a standard Web camera to capture images. Mac OSX will work but it is relatively comfortable in QuickTime, Windows does not have access to capture device WinVDIG and stay, and as a result of the heavy work. It also can capture 640 × 480 screen size is limited.

CaptureDS is, Windows DirectShow environment using Web cameras to capture images of a single function library for Processing (class).

The operation of this library is humatic are available in DirectShow Java is required.

Using the class CaptureDS Basically, Processing and Capture standard compliant. Please see the document.
