java如何自动获取摄像头rtsp地址和其ip

Java可以使用OpenCV库来获取摄像头的rtsp地址和IP。具体实现方法可以参考以下代码：

import org.opencv.core.Core;
import org.opencv.core.Mat;
import org.opencv.videoio.VideoCapture;

public class CameraTest {
static {
System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
}

public static void main(String[] args) {
VideoCapture camera = new VideoCapture(0);
if (!camera.isOpened()) {
System.out.println("摄像头未连接！");
} else {
Mat frame = new Mat();
camera.read(frame);
String rtspUrl = camera.get(Videoio.CAP_PROP_FOURCC);
String ip = camera.get(Videoio.CAP_PROP_POS_MSEC);
System.out.println("rtsp地址：" + rtspUrl);
System.out.println("IP地址：" + ip);
camera.release();
}
}
}

这段代码可以获取摄像头的rtsp地址和IP地址，并输出到控制台上。
