Я хочу одновременно воспроизводить 4 элемента видеообзора по URL потока rtsp, чтобы он воспроизводил 1 элемент, оставшийся не работающим, но если запустить в sumsung node2, можно воспроизвести 3 элемента, оставшиеся не работающими. Как сделать, чтобы для просмотра видео все 4 элемента работали одновременно.

Мой код

      import android.app.Activity;
     import android.media.MediaPlayer;
     import android.media.MediaPlayer.OnPreparedListener;
     import android.net.Uri;
     import android.os.Bundle;
     import android.view.Window;
     import android.widget.MediaController;
     import android.widget.VideoView;

     public class MainActivity extends Activity {

String SrcPath = "rtsp://monitor:monitor@192.168.60.101/MPEG4/ch1/sub/av_stream";
String SrcPath1 = "rtsp://monitor:monitor@192.168.60.102/MPEG4/ch2/sub/av_stream";
String SrcPath2 = "rtsp://monitor:monitor@192.168.60.101/MPEG4/ch3/sub/av_stream";
String SrcPath3 = "rtsp://monitor:monitor@192.168.60.101/MPEG4/ch4/sub/av_stream";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_main);

    VideoView myVideoView1 = (VideoView) findViewById(R.id.videoView1);
    VideoView myVideoView2 = (VideoView) findViewById(R.id.videoView2);
    VideoView myVideoView3 = (VideoView) findViewById(R.id.videoView3);
    VideoView myVideoView4 = (VideoView) findViewById(R.id.videoView4);


    prepareVideo(myVideoView1, SrcPath);
    prepareVideo(myVideoView2, SrcPath1);
    prepareVideo(myVideoView3, SrcPath2);
    prepareVideo(myVideoView4, SrcPath3);

}

public void prepareVideo(final VideoView videoView, String url) {
    try {


        MediaController mediacontroller = new MediaController(this);
        mediacontroller.setAnchorView(videoView);
        videoView.setMediaController(mediacontroller);
        videoView.setVideoURI(Uri.parse(url));


        videoView.setOnPreparedListener(new OnPreparedListener() {
            public void onPrepared(MediaPlayer player) {

                videoView.requestFocus();
                videoView.start();

            }
        });

        //

    } catch (Exception e) {
        System.out.println("Exception caught: "   e.getMessage());
    }
   }

 }

Просто введите этот код и вызовите метод showVideos:
