FFmpegFrameRecorder問題

Question

在使用FFmpegFrameRecorder從JavaCV JVM的以下消息崩潰：

的代碼如下：

package com.opencv.windows; 

import com.googlecode.javacv.CanvasFrame; 
import com.googlecode.javacv.FFmpegFrameGrabber; 
import com.googlecode.javacv.FFmpegFrameRecorder; 
import com.googlecode.javacv.OpenCVFrameGrabber; 
import com.googlecode.javacv.cpp.opencv_core; 

public class VideoRecorderDemo 
{ 
    OpenCVFrameGrabber grabber; 
    FFmpegFrameRecorder recorder; 
    CanvasFrame canvasFrame; 

    VideoRecorderDemo() 
    { 
     grabber = new OpenCVFrameGrabber("c:\\sample.mp4"); 
     recorder = new FFmpegFrameRecorder("c:\\sample1.mp4", 2); 
     canvasFrame = new CanvasFrame("Video Recorder Demo");  
     canvasFrame.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE); 

     try 
     { 
      grabber.start(); 

      opencv_core.IplImage image; 
      while((canvasFrame.isVisible()) && (image = grabber.grab()) != null) 
       canvasFrame.showImage(image); 
     } 
     catch(Exception e) 
     { 
      System.out.println("Error : " + e.getMessage()); 
     } 

     init(); 
     startRecording(); 
     stopRecording(); 
    } 

    void init() 
    { 
     try 
     { 
      grabber.start(); 
      recorder.start(); 
     } 
     catch(Exception e) 
     { 
      System.out.println(e.getMessage()); 
     } 
    } 

    void startRecording() 
    { 
     try 
     { 
      opencv_core.IplImage image; 
      while((canvasFrame.isVisible()) && (image = grabber.grab()) != null) 
      { 
       recorder.record(image); 
       canvasFrame.showImage(image); 
      } 
     } 
     catch(Exception e) 
     { 
      System.out.println(e.getMessage()); 
     } 
    } 

    void stopRecording() 
    { 
     try 
     { 
      grabber.stop(); 
      recorder.stop(); 
      canvasFrame.dispose(); 
     } 
     catch(Exception e) 
     { 
      System.out.println(e.getMessage()); 
     } 
    } 

    public static void main(String args[]) 
    { 
     new VideoRecorderDemo(); 
    } 
} 

我使用的OpenCV 2.4.3庫和從zeronoe提供的ffmpeg庫（ffmpeg-20130209-git-969039e-win64-shared）

謝謝

ü必須使用這個版本的ffmpeg：

http://ffmpeg.zeranoe.com/builds/win64/shared/ffmpeg-20121029-git-11d695d-win64-shared.7z

我有烏爾問題，但我找遍了JavaCV自述文件，我發現JavaCV編譯了該版本的ffmpeg

好運氣
