c# - 如何通过 TCP 通过 Internet 将 Motion JPEG 发送到 Windows Phone

Question

我想使用全局 ip 89.232.123.122 从我的电脑发送动态 JPEG 到 Windows Phone 手机。如何与那个手机建立连接并通过连接推送mjpeg？

Answer 1

要发送多媒体(如动态 JPEG)，请使用 UDP 而不是 TCP。

在发件人端使用此代码:

  UdpClient sendFrame = new UdpClient();
  // your image is img:
  Bitmap img = new Bitmap("pic.png");


  // always send image
  while (true)
                {
      MemoryStream memory_Stream = new MemoryStream();
      // convert bitmap to jpg
      SaveJPG100(img, memory_Stream);

      byte[] byte_Of_Frame = memory_Stream.ToArray();
     // send data on port 2000 on remote host
     sendFrame.Send(byte_Of_Frame, byte_Of_Frame.Length,"89.232.123.122",2000);

                }

//将 btm 转换为 jpg

public void SaveJPG100(Bitmap bmp, System.IO.Stream stream)
{

    EncoderParameters encoderParameters = new EncoderParameters(1);
    encoderParameters.Param[0] = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 100L);
    bmp.Save(stream, GetEncoder(ImageFormat.Jpeg), encoderParameters);
}

// generate jpg description
public ImageCodecInfo GetEncoder(ImageFormat format)
{

    ImageCodecInfo[] codecs = ImageCodecInfo.GetImageDecoders();

    foreach (ImageCodecInfo codec in codecs)
    {
        if (codec.FormatID == format.Guid)
        {
            return codec;
        }
    }
    return null;
}

在接收方使用此代码

            UdpClient receiveFrame = new UdpClient(2000);
            // recieve data from any ip address and any port
            IPEndPoint remote = new IPEndPoint(IPAddress.ANY, 0);

            while (true)
            {

                byte[] byte_Of_Frame = receiveFrame.Receive(ref remote);
                MemoryStream ms = new MemoryStream(byte_Of_Frame);

                pictureBox1.Image=(new Bitmap(ms));
            }
