why RTSP Video url is showing no Video in my Picturebox

I'm trying to implement RTSP url for live view of camera with AForge.Video.DirectShow;

here's my code

private VideoCaptureDevice videoSource; public camtest3() { InitializeComponent(); } private void camtest3_Load(object sender, EventArgs e) { // Create a new instance of the VideoCaptureDevice class using the RTSP URL videoSource = new VideoCaptureDevice("rtsp://IP:554/av0_1"); // Register the NewFrame event handler to capture each new video frame videoSource.NewFrame += new NewFrameEventHandler(VideoCaptureDevice_NewFrame); // Start capturing video videoSource.Start(); } private void VideoCaptureDevice_NewFrame(object sender, NewFrameEventArgs eventArgs) { // Display the video frame in a picture box control named pictureBox1 pictureBox1.Image = (Bitmap)eventArgs.Frame.Clone(); } 

while using breakpoints i noticed that the call is never going to pictureBox1.Image = (Bitmap)eventArgs.Frame.Clone();

i have installed the below libraries

The code is working without any Error but no Video displayed
