JavaCV crashes when using FFmpeg on Windows

[GoogleCodeExporter]

What steps will reproduce the problem?
1.download javacv 0.4
2.Try to create an FFmpegframegrabber
3.

What is the expected output? What do you see instead?
import static com.googlecode.javacv.cpp.avformat.*;

import java.awt.image.BufferedImage;

import com.google.sites.lvgeeks.deepthought.utils.img_displayer;
import com.googlecode.javacv.FFmpegFrameGrabber;
import com.googlecode.javacv.FFmpegFrameRecorder;
import com.googlecode.javacv.FrameGrabber.Exception;
import com.googlecode.javacv.cpp.avformat.AVFormatContext;

public class ffmpegtest {

    public static void main(String[] args) throws Exception
    {

        img_displayer win = new img_displayer(640,480);

            System.out.println("create grabber");
    FFmpegFrameGrabber grabber = new FFmpegFrameGrabber("drop.avi");
    System.out.println("start grabber");
    grabber.start();

    while(true)
    {
        BufferedImage buf = grabber.grab().getBufferedImage();
        win.img=buf;
    }
    }

}

Img_displayer is a class that simply displays a bufferedimage in a JFrame

i get the error

Yes, it seems like those newer Windows builds of FFmpeg don't work.. I'll have 
to check out why.

I'm pretty sure FFmpeg 1.0 worked with JavaCV 0.3

how would I package the libraries?
just jar the directory?

Yes, as per the build scripts in the archive. But it turns out is isn't the 
DLLs of FFmpeg that are the problem, but the way we need to link to them:
http://ffmpeg.org/platform.html#Linking-to-FFmpeg-with-Microsoft-Visual-C_002b_0
02b
I'm attaching updated javacv-windows JAR files. Let me know if you still have 
problems with those (they work fine here), thanks.

Hi, can these Jars please be deployed into the repository at 
http://maven2.javacpp.googlecode.com/git

since using maven things will not work out of the box

Sure, ok, it won't do much damage to update the binaries there I suppose :) 
Done:
