linux中c语言实现实时视频传输完整代码

这是一个使用 C 语言在 Linux 系统下实现实时视频传输的完整代码：

#include <string.h>
#include <sys/types.h>
#include <sys/socket.h>

        exit(1);
    }

    // 读取视频文件并发送
    while ((n = fread(buf, 1, BUFSIZE, fp)) > 0)
    {
        printf("Sending %d bytes\n", n);
        sendto(sockfd, buf, n, 0, (struct sockaddr *)&client_addr, len);
    }

}

int main(int argc, char *argv[])
{
    // 创建套接字
    sockfd = socket(AF_INET, SOCK_DGRAM, 0);
