使用linux c语言编写RTP客户端,要求完整实现RTP协议

实现完整的RTP协议需要更复杂的代码和逻辑。下面是一个基于C语言的简单RTP客户端示例，演示了如何发送和接收RTP数据包：

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

#define RTP_PORT 1234
#define BUFFER_SIZE 1024

typedef struct {
    unsigned short version:2;
    unsigned short padding:1;
    unsigned short extension:1;
    unsigned short csrcCount:4;
    unsigned short marker:1;
    unsigned short payloadType:7;
    unsigned short sequenceNumber;
    unsigned int timestamp;
    unsigned int ssrc;
} RTPHeader;

int main() {
    int sockfd;
    struct sockaddr_in server_addr;
    char buffer[BUFFER_SIZE];
    RTPHeader *header;

    // 创建套接字
    sockfd = socket(AF_INET, SOCK_DGRAM, 0);
    if (sockfd < 0) {
        perror("Failed to create socket");
        exit(EXIT_FAILURE);
    }

    // 设置服务器地址
    memset(&server_addr, 0, sizeof(server_addr));
    server_addr.sin_family = AF_INET;
    server_addr.sin_port = htons(RTP_PORT);
    if (inet_pton(AF_INET, "127.0.0.1", &(server_addr.sin_addr)) <= 0) {
        perror("Invalid address");
        exit(EXIT_FAILURE);
    }

    // 发送RTP数据包
    header = (RTPHeader *)buffer;
    memset(buffer, 0, BUFFER_SIZE);

    // 填充RTP头部
    header->version = 2
