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 <stdio.h> #include <stdlib.h> #include <unistd.h> #include <string.h> #include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h> #include <sys/time.h> #include <pthread.h> #include <signal.h>

#define PORT 8000 #define BUFSIZE 1024

int sockfd; struct sockaddr_in server_addr; struct sockaddr_in client_addr; char buf[BUFSIZE]; int len; int n;

void *send_video(void *arg) { // 初始化视频文件 FILE *fp = fopen("video.mp4", "r"); if (fp == NULL) { printf("Error opening file\n"); 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);
}

// 关闭文件和套接字
fclose(fp);
close(sockfd);
pthread_exit(NULL);

}

int main(int argc, char *argv[]) { // 创建套接字 sockfd = socket(AF_INET, SOCK_DGRAM, 0); if (sockfd < 0) { printf("Error creating socket\n"); exit(1); }

// 绑定服务器地址
memset((char *)&server_addr, 0, sizeof(server_addr));
server_addr.sin_family = AF_INET;
server_addr.sin_addr.s_addr = htonl(INADDR_ANY);
server_addr.sin_port = htons(PORT);
if (bind(sockfd, (struct sockaddr *)&amp;server_addr, sizeof(server_addr)) < 0)
{
    printf("Error binding\n");
    exit(1);
}

// 初始化客户端地址
len = sizeof(client_addr);
memset((char *)&amp;client_addr, 0, sizeof(client_addr));
client_addr.sin_family = AF_INET;
client_addr.sin_addr.s_addr = inet_addr("127.0.
