通過套接字發送視頻幀

我使用Kinect設備捕獲視頻流。我需要通過網絡發送這些流。爲此我使用了插座。她是在服務器和客戶端的代碼：通過套接字發送視頻幀

private System.Drawing.Bitmap _CurrentBitmap; 
    public ManWindow() 
    { 
     InitializeComponent(); 

     this.Loaded += delegate 
     { 
      BackgroundWorker bw1 = new BackgroundWorker(); 
      bw1.RunWorkerCompleted += (a, b) => bw1.RunWorkerAsync(); 
      bw1.DoWork += delegate { SendImage(); }; 
      bw1.RunWorkerAsync(); 
     }; 
    } 
    public void SendImage() 
    { 
     Socket sListen = new Socket(AddressFamily.InterNetwork, 
            SocketType.Stream, 
            ProtocolType.Tcp); 

     IPAddress IP = IPAddress.Parse("127.0.0.1"); 
     IPEndPoint IPE = new IPEndPoint(IP, 4321); 

     sListen.Bind(IPE); 
     sListen.Listen(2); 

     while (true) 
     { 
      Socket clientSocket; 
      clientSocket = sListen.Accept(); 

      var converter = new System.Drawing.ImageConverter(); 
      byte[] buffer = (byte[])converter.ConvertTo(_CurrentBitmap, typeof(byte[])); 
      clientSocket.Send(buffer, buffer.Length, SocketFlags.None); 
     } 
    }

客戶：

private void Window_Loaded(object sender, RoutedEventArgs e) 
    { 
     BackgroundWorker bw11111 = new BackgroundWorker(); 
     bw11111.RunWorkerCompleted += (a, b) => bw11111.RunWorkerAsync(); 
     bw11111.DoWork += delegate { Recive(); }; 
     bw11111.RunWorkerAsync(); 
     Recive(); 
    } 

    public void Recive() 
    { 
     Socket s = new Socket(AddressFamily.InterNetwork, 
          SocketType.Stream, 
          ProtocolType.Tcp); 

     IPAddress IP = IPAddress.Parse("127.0.0.1"); 
     IPEndPoint IPE = new IPEndPoint(IP, 4321); 
     s.Connect(IPE); 

     while (true) 
     { 

      byte[] buffer = new byte[1000000]; 

      s.Receive(buffer, buffer.Length, SocketFlags.None); 

      MemoryStream ms = new MemoryStream(buffer); 

      ms.Write(buffer, 0, buffer.Length); 
      System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(ms); 

      Dispatcher.BeginInvoke(new Action(() => 
      { 
       rgbImage11.Source = bitmap.ToBitmapSource(); 
      })); 

     } 
    }

_CurrentBitmap是幀從Kinect和每1秒更新readed。當客戶端啓動時，調用套接字接收方法，它接收幀並在轉換爲位圖後將其命名爲圖像WPF控件。我的問題是，這種行爲發生在客戶端循環不重複。

只是猜測，但一旦你發送圖像在服務器中，你的套接字超出範圍，所以我想客戶端失去了連接，並死亡。 – Chris 2012-08-07 11:59:47

沒有發生任何錯誤，爲什麼接收方法調用一次？還有另一種發送視頻的方式嗎？ – 2012-08-07 12:14:29

我認爲你做得對，雖然取決於你的需要UDP套接字可能會更有意義。試着改變你的服務器的代碼是這樣的：

while (true) 
{ 
    Socket clientSocket; 
    clientSocket = sListen.Accept(); 

    var converter = new System.Drawing.ImageConverter(); 
    while(true) // find a better way to determine that the picture is still updating? 
    { 
     byte[] buffer = (byte[])converter.ConvertTo(_CurrentBitmap, typeof(byte[])); 
     clientSocket.Send(buffer, buffer.Length, SocketFlags.None); 
    } 
}

您發送了一個位圖到客戶端，然後掉下來循環。套接字不會保持打開狀態，所以您的客戶端運行一次循環。

謝謝，它工作。如果在服務器環路中發送位圖失敗，如何在客戶端重新連接到服務器？ – 2012-08-07 12:46:39
