Criando веб-камера с COM в C# форм Windows

---

как сохранить видео или записать его в форме c# windows? мне надоел мой бедный английский.

Что я уже пробовал:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using AForge.Video;
using AForge.Video.DirectShow;
using System.Drawing.Imaging;
using System.Timers;


namespace WebCam
{
    public partial class Form1 : Form
    {

        Image capturaImagem;
        public string caminhoImagemSalva = null;
        private bool ExistenDispositivos = false;
        private FilterInfoCollection DispositivosDeVideo;
        private VideoCaptureDevice FluenteDeVideo = null;
        private AVIWriter VideoWriter = new AVIWriter("wmv3");
        private VideoCaptureDevice FinalVideo = null;
        private VideoCaptureDeviceForm captureDevice;
        Bitmap Image;
        private Bitmap video;

        private SaveFileDialog saveAvi;

        public Form1()
        {
            InitializeComponent();
            BuscarDipositivos();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            DispositivosDeVideo = new FilterInfoCollection(FilterCategory.VideoInputDevice);
            FluenteDeVideo = new VideoCaptureDevice();

        }
        public void CaregarDispositivos(FilterInfoCollection Dispositivos)
        {
            for (int i = 0; i < Dispositivos.Count; i++)
                comboBox1.Items.Add(Dispositivos[i].Name.ToString());
            comboBox1.Text = comboBox1.Items[0].ToString();
        }
        public void BuscarDipositivos()
        {
            DispositivosDeVideo = new FilterInfoCollection(FilterCategory.VideoInputDevice);
            if (DispositivosDeVideo.Count == 0)
                ExistenDispositivos = false;
            else
            {
                ExistenDispositivos = true;
                CaregarDispositivos(DispositivosDeVideo);
            }
        }
}
