一：配置opencv，网络上面很多配置opencv的文章，这里就不多说了，[https://blog.csdn.net/sinat\_38102206/article/details/81156589][https_blog.csdn.net_sinat_38102206_article_details_81156589]  
二：上代码

<dependency>
                <groupId>org.bytedeco</groupId>
                <artifactId>javacv-platform</artifactId>
                <version>1.4.4</version>
            </dependency>

@Test
        public void testzc() throws FrameGrabber.Exception {
            String file = "rtsp://192.168.2.38:5554/2";
            FFmpegFrameGrabber grabber = FFmpegFrameGrabber.createDefault(file);
            grabber.setOption("rtsp_transport", "tcp"); // 使用tcp的方式，不然会丢包很严重
            // 一直报错的原因！！！就是因为是 2560 * 1440的太大了。。
            grabber.setImageWidth(960);
            grabber.setImageHeight(540);
            System.out.println("grabber start");
            grabber.start();
            CanvasFrame canvasFrame = new CanvasFrame("sdsaf");
            canvasFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            canvasFrame.setAlwaysOnTop(true);
            OpenCVFrameConverter.ToMat converter = new OpenCVFrameConverter.ToMat();
           // OpenCVFrameConverter.ToIplImage converter = new OpenCVFrameConverter.ToIplImage();
            while (true){
                Frame frame = grabber.grabImage();
                opencv_core.Mat mat = converter.convertToMat(frame);
                canvasFrame.showImage(frame);
            }
    
        }

三：看效果
