通过套接字发送视频帧

我使用Kinect设备捕获视频流。我需要通过网络发送这些流。为此我使用了插座。她是在服务器和客户端的代码：通过套接字发送视频帧

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); 
     } 
    }

客户：

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是帧从Kinect和每1秒更新readed。当客户端启动时，调用套接字接收方法，它接收帧并在转换为位图后将其命名为图像WPF控件。我的问题是，这种行为发生在客户端循环不重复。

只是猜测，但一旦你发送图像在服务器中，你的套接字超出范围，所以我想客户端失去了连接，并死亡。 – Chris 2012-08-07 11:59:47

没有发生任何错误，为什么接收方法调用一次？还有另一种发送视频的方式吗？ – 2012-08-07 12:14:29

我认为你做得对，虽然取决于你的需要UDP套接字可能会更有意义。试着改变你的服务器的代码是这样的：

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); 
    } 
}

您发送了一个位图到客户端，然后掉下来循环。套接字不会保持打开状态，所以您的客户端运行一次循环。

谢谢，它工作。如果在服务器环路中发送位图失败，如何在客户端重新连接到服务器？ – 2012-08-07 12:46:39
