import org.opencv.core.*;
import org.opencv.imgcodecs.Imgcodecs;
import org.opencv.core.Core;
import org.opencv.videoio.VideoCapture;

public class VideoCap {
    public static void main (String args[]){
        System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
        VideoCapture camera = new VideoCapture("http://86.45.26.248:8080/?action=stream?dummy=param.mjpg");
        if(!camera.isOpened()){
            System.out.println("Error");
        }
        else {
            Mat frame = new Mat();
            while(true){
                if (camera.read(frame)){
                    System.out.println("Frame Obtained");
                    System.out.println("Captured Frame Width " + 
                    frame.width() + " Height " + frame.height());
                    Imgcodecs.imwrite("camera.jpg", frame);
                    System.out.println("OK");
                    break;
                }
            }   
        }
