帮我写一个socket接口，udp协议实现摄像头调用的代码，OpenCV4.0，C++

以下是一个简单的UDP Socket接口，用于发送OpenCV摄像头捕获的图像数据：

#include <opencv2/opencv.hpp>
#include <iostream>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <unistd.h>
#include <cstring>

using namespace cv;
using namespace std;

#define PORT 8888

int main() {
    // 创建UDP Socket
    int sockfd = socket(AF_INET, SOCK_DGRAM, 0);
    if (sockfd < 0) {
        cerr << "Failed to create socket." << endl;
        return -1;
    }
    
    // 设置Socket选项
    int optval = 1;
    setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, (const void *)&optval, sizeof(int));
    
    // 设置服务器地址
    struct sockaddr_in serv_addr;
    memset(&serv_addr, 0, sizeof(serv_addr));
    serv_addr.sin_family = AF_INET;
    serv_addr.sin_port = htons(PORT);
    serv_addr.sin_addr.s_addr = htonl(INADDR_ANY);
    
    // 绑定Socket
    if (bind(sockfd, (struct sockaddr *)&serv_addr, sizeof(serv_addr)) < 0) {
        cerr << "Failed to bind socket." << endl;
        return -1;
    }
    
    // 开始捕获摄像头图像
    VideoCapture cap(0);
    if (!cap.isOpened()) {
        cerr << "Failed to open camera." << endl;
        return -1;
    }
    
    // 设置视频编码参数
    int codec = VideoWriter::fourcc('M', 'J', 'P', 'G');
    double fps = 25.0;
    int width = cap.get(CAP_PROP_FRAME_WIDTH);
    int height = cap.get(CAP_PROP_FRAME_HEIGHT);
    int quality = 90;
    
    // 按帧捕获并发送图像
    Mat frame;
    struct sockaddr_in cli_addr;
    socklen_t len = sizeof(cli_addr);
    while (true) {
        cap >> frame;
        if (frame.empty()) {
            cerr << "Failed to capture frame." << endl;
            break;
        }
        
        // 将帧转换为JPEG格式
        vector<uchar> buffer;
        vector<int> params = { IMWRITE_JPEG_QUALITY, quality };
        imencode(".jpg", frame, buffer, params);
        
        // 发送JPEG图像
        sendto(sockfd, buffer.data(), buffer.size(), 0, (struct sockaddr *)&cli_addr, len);
    }
    
    // 关闭Socket和摄像头
    close(sockfd);
    cap.release();
    
    return 0;
}

这个程序使用了OpenCV的 VideoCapture 类来捕获摄像头图像，然后将每一帧转换为JPEG格式，并使用UDP Socket发送给客户端。你需要在客户端实现相应的UDP Socket接收代码来接收这些图像数据。
