Swing Java CV 1.0网络摄像头视频捕获：无法将帧转换为IplImage

我无法使用JavaCV/OpenCV/FFMPEG录制网络摄像头视频（即捕获和保存.avi或.mp4文件），我做错了什么

使用的版本（全部64位）

Win 7、NetBeans8.0.2、jdk1.7.0_10、JavaCV 1.0、OpenCV 3.0.0、ffmpeg-2.1.1-win64-shared。

我的系统变量设置为

C:\Program Files\Java\jdk1.7.0_10；%SystemRoot%\system32；%SystemRoot%；%SystemRoot%\System32\Wbem；%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\；C:\Program Files\Intel\WiFi\bin\；C:\Program Files\Common Files\Intel\WirelessCommon\；C:\ProgramFiles（x86）\Intel\OpenCLSDK\2.0\bin\x86；C:\ProgramFiles（x86）\Intel\OpenCLSDK\2.0\bin\x64；C:\ProgramFiles（x86）\MySQL\MySQL Fabric 1.5.4和MySQL Utilities 1.5.4 1.5\；C:\ProgramFiles（x86）\MySQL\MySQL Fabric 1.5.4和MySQL Utilities 1.5.4 1.5\PHP的条令扩展\C:\opencv\build\x64\vc11\bin；C:\ffmpeg\bin

下载并设置路径变量后，我将jar文件添加到Netbeans项目中

C:\opencv\build\java\opencv-300.jar C:\javacv-1.0-bin\javacv-bin\videoinput.jar C:\javacv-1.0-bin\javacv-bin\videoinput-windows-x86\u 64.jar C:\javacv-1.0-bin\javacv-bin\videoinput-windows-x86.jar C:\javacv-1.0-bin\javacv-bin\opencv.jar C:\javacv-1.0-bin\javacv-bin\opencv-windows-x86\u 64.jar C:\javacv-1.0-bin\javacv-bin\opencv-windows-x86.jar C:\javacv-1.0-bin\javacv-bin\libfreenect.jar C:\javacv-1.0-bin\javacv-bin\libfreenect-windows-x86_64.jar C:\javacv-1.0-bin\javacv-bin\libfreenect-windows-x86.jar C:\javacv-1.0-bin\javacv-bin\libdc1394.jar C:\javacv-1.0-bin\javacv-bin\junit.jar C:\javacv-1.0-bin\javacv-bin\javacv.jar C:\javacv-1.0-bin\javacv-bin\javacpp.jar C:\javacv-1.0-bin\javacv-bin\hamcrest-core.jar C:\javacv-1.0-bin\javacv-bin\flycapture.jar C:\javacv-1.0-bin\javacv-bin\flycapture-windows-x86\u 64.jar C:\javacv-1.0-bin\javacv-bin\flycapture-windows-x86.jar C:\javacv-1.0-bin\javacv-bin\flandmark.jar C:\javacv-1.0-bin\javacv-bin\flandmark-windows-x86_64.jar C:\javacv-1.0-bin\javacv-bin\flandmark-windows-x86.jar C:\javacv-1.0-bin\javacv-bin\ffmpeg.jar C:\javacv-1.0-bin\javacv-bin\ffmpeg-windows-x86\u 64.jar C:\javacv-1.0-bin\javacv-bin\ffmpeg-windows-x86.jar C:\javacv-1.0-bin\javacv-bin\artoolkitplus.jar C:\javacv-1.0-bin\javacv-bin\artoolkitplus-windows-x86_64.jar C:\javacv-1.0-bin\javacv-bin\artoolkitplus-windows-x86.jar

问题1:
捕获网络摄像头视频的第一个程序（显示并保存到output.avi文件）如下所示

它显示网络摄像头并创建output.avi。但在媒体播放器中打开文件output.avi时终止程序后，它不会显示任何内容：）

它不起作用

        FrameGrabber grabber = FrameGrabber.createDefault(0);
        grabber.start();

        // CanvasFrame, FrameGrabber, and FrameRecorder use Frame objects to communicate image data.
        // We need a FrameConverter to interface with other APIs (Android, Java 2D, or OpenCV).
        OpenCVFrameConverter.ToIplImage converter = new OpenCVFrameConverter.ToIplImage();


        IplImage grabbedImage = converter.convert(grabber.grab());
        int width  = grabbedImage.width();
        int height = grabbedImage.height();


        FrameRecorder recorder = FrameRecorder.createDefault("output.avi", width, height);
        recorder.start();


        CanvasFrame frame = new CanvasFrame("Some Title");

        while (frame.isVisible() && (grabbedImage = converter.convert(grabber.grab())) != null) {
           // cvWarpPerspective(grabbedImage, rotatedImage, randomR);

            Frame rotatedFrame = converter.convert(grabbedImage);

            //opencv_core.IplImage grabbedImage = grabber.grab();
            frame.showImage(rotatedFrame);
            recorder.record(rotatedFrame);
        }
        frame.dispose();
        recorder.stop();
        grabber.stop();
    }
}

问题2:当我运行以下代码时

opencv_core.IplImage grabbedImage = grabber.grab();  

不兼容类型：无法将框架转换为IplImage出现消息

       Logger.getLogger(JCVdemo.class.getName()).log(Level.SEVERE, null, ex);  
     }  
   }
}  

问题是：我做错了什么

我无法录制任何类型的视频；无论我使用哪个版本的JavaCV/OPenCv

---

请告诉我从网络摄像头录制视频的工作示例，以及JavaCV/OpenCV/FFmpeg兼容版本的工作示例。

使用：

OpenCVFrameConverter

OpenCVFrameConverter.ToIplImage converter = new OpenCVFrameConverter.ToIplImage();
img = converter.convert(grabber.grab());
