视频拆帧处理

                BufferedImage img = converter.getBufferedImage(frame);
                //压缩图片并且保存
                Thumbnails.of(img).scale(0.5).toFile(new File(file.getPath() + File.separator + "frame_" + frameCount + ".jpg"));
            }
            grabber.stop();
            System.out.println("耗时： " + ((System.currentTimeMillis() - millis) / 1000));
