//用來操作攝像頭
 private VideoCaptureDevice Camera = null;
 //用來把每一幀圖像編碼到視頻文件
 private VideoFileWriter VideoOutPut = new VideoFileWriter();


 開始代碼:
 //獲取攝像頭列表
var devs = new FilterInfoCollection(FilterCategory.VideoInputDevice);

//實(shí)例化設(shè)備控制類(我選了第1個)
Camera = new VideoCaptureDevice(devs[0].MonikerString);

//配置錄像參數(shù)(寬,高,幀率,比特率等參數(shù))VideoCapabilities這個屬性會返回?cái)z像頭支持哪些配置,從這里面選一個賦值接即可,我選了第1個
Camera.VideoResolution = Camera.VideoCapabilities[0];

//設(shè)置回調(diào),aforge會不斷從這個回調(diào)推出圖像數(shù)據(jù)
Camera.NewFrame += Camera_NewFrame;

//打開攝像頭
Camera.Start();

//打開錄像文件(如果沒有則創(chuàng)建,如果有也會清空),這里還有關(guān)于
VideoOutPut.Open("E:/VIDEO.MP4", 
　　　　Camera.VideoResolution.FrameSize.Width, 
　　　　Camera.VideoResolution.FrameSize.Height, 
　　　　Camera.VideoResolution.AverageFrameRate, 
　　　　VideoCodec.MPEG4, 
　　　　Camera.VideoResolution.BitCount);
給AForge輸出圖像數(shù)據(jù)的回調(diào)方法:
//圖像緩存
private Bitmap bmp = new Bitmap(1, 1);

//攝像頭輸出回調(diào)
private void Camera_NewFrame(object sender, NewFrameEventArgs eventArgs)
{
 //寫到文件
 VideoOutPut.WriteVideoFrame(eventArgs.Frame);
 lock (bmp)
 {
  //釋放上一個緩存
  bmp.Dispose();
  //保存一份緩存
  bmp = eventArgs.Frame.Clone() as Bitmap;
 }
}

   //停攝像頭
   Camera.Stop();

   //關(guān)閉錄像文件,如果忘了不關(guān)閉,將會得到一個損壞的文件,無法      
   VideoOutPut.Close();
