C# 通过UDP 远程监控摄像头
背景： 项目需要到网上想下载一个UDP远程通信的例子，但是居然没有下到合适的例子。

实现效果
关键代码：
客户端 采集摄像头数据 通过UDP发送
private void CameraConn()
{
videoSource = new VideoCaptureDevice(videoDevices[comboBox1.SelectedIndex].MonikerString);
videoSourcePlayer1.VideoSource = videoSource;
videoSourcePlayer1.NewFrame += videoPlayer_RGB_NewFrame;
videoSourcePlayer1.Start();
}
void videoPlayer_RGB_NewFrame(object sender, ref Bitmap image)
{
var ip = IPAddress.Parse(server.Text);
var multicast = new IPEndPoint(ip, 4444);
MemoryStream ms = new MemoryStream();
image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
byte[] bytes = new byte[ms.Length];
bytes = ms.ToArray();
client.Send(bytes, bytes.Length, multicast);
//Thread.Sleep(1);
}
服务端代码：
private void Form1_Load(object sender, EventArgs e)
{
//创建等待连接线程
Thread thread = new Thread(new ThreadStart(waitConnect));
thread.IsBackground = true;
thread.Start();
}
private void waitConnect()
{
client = new UdpClient(new IPEndPoint(IPAddress.Any, UDP_PORT));
//启动接收线程
Thread thread = new Thread(new ThreadStart(recvImage));
thread.IsBackground = true;
thread.Start();
}
private void recvImage()
{
while(true)
{
//接受图像帧数据
byte[] recvBuf = client.Receive(ref remote);
MemoryStream ms = new MemoryStream(recvBuf);
try
{
//显示到pictureBox上
pictureBox1.Image = Image.FromStream(ms);
}
catch (ArgumentException)
{ }
}
}
