        int second = 0;
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            writer.VideoCodec = VideoCodec.H264;
            writer.Width = Screen.PrimaryScreen.Bounds.Width;
            writer.Height = Screen.PrimaryScreen.Bounds.Height;
            writer.BitRate = 1000000;
            writer.Open("D:/DemoVideo.mp4");

            RecordTimer.Interval = 40;
            RecordTimer.Start();

        }

        private void RecordTimer_Tick(object sender, EventArgs e)
        {
            Rectangle bounds = Screen.GetBounds(Point.Empty);
            using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))

                using (Graphics g = Graphics.FromImage(bitmap))
                {
                    g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
                }
                writer.WriteVideoFrame(bitmap);
            }

            textBox1.Text = RecordTimer.ToString();
            second ++;
            if(second > 1500)
            {
                RecordTimer.Stop();
                RecordTimer.Dispose();
                writer.Close();
                writer.Dispose();
            }
        }
    }
