    void stopRecording()

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

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

我正在使用OpenCV 2.4.3库和zeronoe提供的ffmpeg库（ffmpeg-20130209-git-969039e-win64-shared）

谢谢

你必须使用这个版本的ffmpeg：

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

我有你的问题，但我搜索了JavaCV自述文件，我发现JavaCV已经用这个版本的ffmpeg编译

祝你好运
