如何以无损格式录制网络摄像头的视频？

Question

我正在尝试编写一个可以无损格式录制视频的应用程序。为此，我使用Webcam-Capture和Xuggler库。一切正常但外播视频有以下工件：

这并不是在所有帧中观察到的，几乎是5个帧中的一个。我的代码：

@FXML
public void record() {
            File file = new File("output.wmv");

            IMediaWriter writer = ToolFactory.makeWriter(file.getName());
            Dimension size = WebcamResolution.VGA.getSize();

            writer.addVideoStream(0, 0, ICodec.ID.CODEC_ID_RAWVIDEO, size.width, size.height);

            Webcam webcam = Webcam.getDefault();
            webcam.setViewSize(size);
            webcam.open(true);

            long start = System.currentTimeMillis();

            for (int i = 0; i < 50; i++) {

                System.out.println("Capture frame " + i);

                BufferedImage image = ConverterFactory.convertToType(webcam.getImage(), BufferedImage.TYPE_3BYTE_BGR);
                IConverter converter = ConverterFactory.createConverter(image, IPixelFormat.Type.YUV420P);

                IVideoPicture frame = converter.toPicture(image, (System.currentTimeMillis() - start) * 1000);
                frame.setKeyFrame(i == 0);
                frame.setQuality(100);

                writer.encodeVideo(0, frame);

                // 10 FPS
                try {
                    Thread.sleep(40);
                } catch (InterruptedException e) {
                    e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
                }
            }

            writer.close();

            System.out.println("Video recorded in file: " + file.getAbsolutePath());

}

我做错了什么？
