Nothing happens :-(

Hi
I have this code writen:

using DotImaging;
using System;
using System.Windows.Forms;

namespace youtube_new_c
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

            var sourceName = String.Empty;

            var pipeName = new Uri("https://www.youtube.com/watch?v=Vpg9yizPP_g").NamedPipeFromYoutubeUri(); //Youtube

            sourceName = String.Format(@"\\.\pipe\{0}", pipeName);

            
            ImageStreamReader reader = new FileCapture(sourceName);
            reader.Open();

            //seek if you can
            if (reader.CanSeek)
                reader.Seek((int)(reader.Length * 0.25), System.IO.SeekOrigin.Begin);

            //read video frames
            Bgr<byte>[,] frame = null;
            do
            {
                reader.ReadTo(ref frame);
                if (frame == null)
                    break;
                
                frame.Show(scaleForm: true);
                ((double)reader.Position / reader.Length).Progress();
            }
            while (!(Console.KeyAvailable && Console.ReadKey(true).Key == ConsoleKey.Escape));

        }
    }
}

and when run i got a black window, one empty form and another form with a progressbar but nothing happens. Any idea of what i need to do?
Thanks
