如何使用C＃桌面应用程序在MPEG，AVI，MP4或WMV中记录WebCam视频。

问题描述

我正在开发桌面应用程序，它要求我连接到网络摄像头并以MPEG，AVI，MP4和WMV格式录制（保存）视频并刻录到CD / DVD中。该应用程序是在Win Forms中。我对基于Web的Flash / Silver light解决方案不感兴趣我只对免费或开源解决方案或控件感兴趣。



我使用Aforge保存为AVI。净，但它需要更多的尺寸保存（如15sce 320x240视频60-100MB）。我对10sce除了1MB。

C＃/ .NET有这样的解决方案吗？

这是代码：

I am working on Desktop Application which requires me to connect to webcam(s) and record(save) the video in MPEG, AVI, MP4 and WMV formats and Burn into the CD/DVD. The application is in Win Forms. I am not interested in Web Based Flash/Silver light solutions I am only interested in free or open source solutions or controls.

I had done saving as AVI using Aforge.Net but its taking more size to save(like 60-100MB for 15sce 320x240 Video ). i am excepting 1MB for 10sce.
Is there such solution available for C#/.NET?
Here is the Code :

using System;
using System.Drawing;
using System.Windows.Forms;
using AForge.Video;
using AForge.Video.DirectShow;
using AForge.Video.VFW;

namespace Aforge_Web_Cam

    {
        private FilterInfoCollection VideoCaptureDevices;
        private VideoCaptureDevice FinalVideo = null;
        private VideoCaptureDeviceForm captureDevice;
        private Bitmap video;
        private AVIWriter AVIwriter = new AVIWriter();
        private SaveFileDialog saveAvi;

        public VideoForm()
        {
            InitializeComponent();
        }

        private void VideoForm_Load(object sender, EventArgs e)
        {
            VideoCaptureDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
            captureDevice = new VideoCaptureDeviceForm();
        }

        private void butStart_Click(object sender, EventArgs e)
        {
            if (captureDevice.ShowDialog(this) == DialogResult.OK)
            {
                VideoCaptureDevice videoSource = captureDevice.VideoDevice;
                FinalVideo = captureDevice.VideoDevice;
                FinalVideo.NewFrame += new NewFrameEventHandler(FinalVideo_NewFrame);
                FinalVideo.Start();
            }
        }

                if (FinalVideo == null)
                { return; }
                if (FinalVideo.IsRunning)
                {
                    //this.FinalVideo.Stop();
                    this.AVIwriter.Close();
                    pbVideo.Image = null;
                }
