What version of the product are you using? On what operating system?
Windows 7 (64bit), java 32bit, opencv 2.2 32bit

Please provide any additional information below.

That is the code:
import static com.googlecode.javacv.cpp.opencv_core.*;
import static com.googlecode.javacv.cpp.opencv_imgproc.*;
import static com.googlecode.javacv.cpp.opencv_highgui.*;

public class Vision {

    public static void main(String [] args){

        //smooth("pic.jpg");
        openVideo("tree.avi");

    }

    public static void smooth(String filename) { 

        IplImage image = cvLoadImage(filename);
        if (image != null) {
            cvSmooth(image, image, CV_GAUSSIAN, 3);
            cvSaveImage(filename, image);
            cvReleaseImage(image);
        }
    }

    public static void openVideo(String filename){

        CvCapture video=cvCreateFileCapture(filename);

        if(video==null){
            return ;
        }

        cvReleaseCapture(video);
    }
}

Smooth image works good. But opening window brings the error.

This is a known problem with OpenCV on Windows. Don't use OpenCV, use 
FFmpegFrameGrabber.

I changed to FFmpegFrameGrabber but now I get UnsatisfiedLinkError.
I have downloaded FFmpeg (32 bit) and set system path.

What is "FFmpeg (32 bit)" exactly?

FFmpeg 0.6.x or 0.7.x Precompiled for Windows. I downloaded it from here 
http://hawkeye.arrozcru.org/builds/win32/shared/. I supose I need that for 
FFmpegFrameGrabber.

And what does the README.txt file of JavaCV say?

Sory, miss that completly. Now FFmpegFrameGrabber works but when I try to use 
IplImage, I get the same error (UnsatisfiedLinkError).
I have tried OpenCV 2.3, OpenCV 2.2 (compiled for MinGW) and OpenCV 2.2 VS2010, 
all the same. I set PATH and install Microsoft Visual C++ 2010 Redistributable 
Package (x86). Java, OpenCV and windows (different computer) are 32bit. My PATH 
is C:\JavaCV\OpenCV2.2\bin.

As indicated in the README.txt file, if you use the latest version of JavaCV, 
you will need OpenCV 2.3.0, not OpenCV 2.2.0
