  我有一个示例代码来使用com.xuggle包记录屏幕

  import java.awt.AWTException;
  import java.awt.Dimension;
  import java.awt.Rectangle;
  import java.awt.Robot;
  import java.awt.Toolkit;
  import java.awt.image.BufferedImage;
  import java.util.concurrent.TimeUnit;
  
  import com.xuggle.mediatool.IMediaWriter;
  import com.xuggle.mediatool.ToolFactory;
  import com.xuggle.xuggler.ICodec;
  
  public class ScreenRecordingExample {
  
      private static final double FRAME_RATE = 50;
  
  private static final int SECONDS_TO_RUN_FOR = 20;
  
      private static final String outputFilename = "c:/mydesktop.mp4";
  
      private static Dimension screenBounds;
  
      public static void main(String[] args) {
  
          // let's make a IMediaWriter to write the file.
      final IMediaWriter writer = ToolFactory.makeWriter(outputFilename);
  
          screenBounds = Toolkit.getDefaultToolkit().getScreenSize();
  
          // We tell it we're going to add one video stream, with id 0,
          // at position 0, and that it will have a fixed frame rate of FRAME_RATE.
          writer.addVideoStream(0, 0, ICodec.ID.CODEC_ID_MPEG4, 
                     screenBounds.width/2, screenBounds.height/2);
  
          long startTime = System.nanoTime();
  
          for (int index = 0; index < SECONDS_TO_RUN_FOR * FRAME_RATE; index++) {
  
              // take the screen shot
              BufferedImage screen = getDesktopScreenshot();
  
              // convert to the right image type
              BufferedImage bgrScreen = convertToType(screen, 
                 BufferedImage.TYPE_3BYTE_BGR);
  
              // encode the image to stream #0
              writer.encodeVideo(0, bgrScreen, System.nanoTime() - startTime, 
                     TimeUnit.NANOSECONDS);
  
              // sleep for frame rate milliseconds
              try {
                  Thread.sleep((long) (1000 / FRAME_RATE));
              } 
              catch (InterruptedException e) {
                  // ignore
              }
  
          }
  
          // tell the writer to close and write the trailer if  needed
          writer.close();
  
      }
  
      public static BufferedImage convertToType(BufferedImage sourceImage, int targetType) {
  
          BufferedImage image;
  
          // if the source image is already the target type, return the source image
          if (sourceImage.getType() == targetType) {
              image = sourceImage;
          }
          // otherwise create a new image of the target type and draw the new image
          else {
              image = new BufferedImage(sourceImage.getWidth(), 
                   sourceImage.getHeight(), targetType);
          image.getGraphics().drawImage(sourceImage, 0, 0, null);
          }
  
          return image;
  
      }
  
      private static BufferedImage getDesktopScreenshot() {
          try {
              Robot robot = new Robot();
          Rectangle captureSize = new Rectangle(screenBounds);
          return robot.createScreenCapture(captureSize);
          } 
          catch (AWTException e) {
              e.printStackTrace();
              return null;
          }
  
      }
  
  }
