RTSP(Real-Time Streaming Protocol)是一种网络协议,用于控制实时多媒体数据,如视频流。要在C语言中通过TCP获取RTSP数据,你需要使用一些库,比如libavcodec(处理解码),libavformat(处理格式转换和网络传输)以及libsocket(处理TCP连接)。以下是一个简单的示例,展示了如何使用libavformat建立TCP连接并接收RTSP数据:
```c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/socket.h>
#include <arpa/inet.h>
#include "libavformat/avformat.h"
#define BUFFER_SIZE 4096
int main(int argc, char *argv[]) {
int sock = socket(AF_INET, SOCK_STREAM, 0);
struct sockaddr_in server_addr;
memset(&server_addr, 0, sizeof(server_addr));
server_addr.sin_family = AF_INET;
server_addr.sin_port = htons(554); // RTSP默认端口
inet_pton(AF_INET, "your_server_ip", &server_addr.sin_addr);
if (connect(sock, (struct sockaddr *)&server_addr, sizeof(server_addr)) < 0) {
perror("Error connecting to server");
return 1;
}
char buffer[BUFFER_SIZE];
while (1) {
ssize_t bytes_received = recv(sock, buffer, BUFFER_SIZE, 0);
if (bytes_received <= 0) {
perror("Error receiving data");
break;
}
// 解析接收到的数据,这里假设是raw RTP数据,实际可能需要AVFormatContext解析
// buffer bytes_received bytes
printf("Received %zd bytes from server\n", bytes_received);
}
close(sock);
return 0;
}
