java rtsp请求示例

以下是一个使用Java进行RTSP请求的示例：

import java.io.*;
import java.net.*;

public class RtspClient {
    
    private static final String RTSP_VERSION = "RTSP/1.0";
    private static final String CRLF = "\r\n";
    
    public static void main(String[] args) throws Exception {
        
        String serverAddress = "example.com";
        int serverPort = 554;
        String url = "rtsp://" + serverAddress + ":" + serverPort + "/test.mp4";
        
        // Establish TCP connection with server
        Socket rtspSocket = new Socket(serverAddress, serverPort);
        BufferedReader inputReader = new BufferedReader(new InputStreamReader(rtspSocket.getInputStream()));
        OutputStream outputStream = rtspSocket.getOutputStream();
        
        // Send RTSP OPTIONS request
        String optionsRequest = "OPTIONS " + url + " " + RTSP_VERSION + CRLF +
                                "CSeq: 1" + CRLF +
                                "User-Agent: My RTSP Client" + CRLF +
                                CRLF;
        outputStream.write(optionsRequest.getBytes());
        System.out.println("OPTIONS request sent.");
        
        // Read RTSP OPTIONS response
        String optionsResponse = "";
        String inputLine;
        while ((inputLine = inputReader.readLine()) != null) {
            optionsResponse += inputLine + "\n";
            if (inputLine.equals(""))
                break;
        }
        System.out.println("OPTIONS response received:\n" + optionsResponse);
        
        // Send RTSP DESCRIBE request
        String describeRequest = "DESCRIBE " + url + " " + RTSP_VERSION + CRLF +
                                 "CSeq: 2" + CRLF +
                                 "User-Agent: My RTSP Client" + CRLF +
                                 "Accept: application/sdp" + CRLF +
                                 CRLF;
        outputStream.write(describeRequest.getBytes());
        System.out.println("DESCRIBE request sent.");
        
        // Read RTSP DESCRIBE response
        String describeResponse = "";
        while ((inputLine = inputReader.readLine()) != null) {
            describeResponse += inputLine + "\n";
            if (inputLine.equals(""))
                break;
        }
        System.out.println("DESCRIBE response received:\n" + describeResponse);
        
        // Close the RTSP socket
        rtspSocket.close();
    }
}

这个示例通过建立TCP连接与RTSP服务器进行通信，发送RTSP OPTIONS和DESCRIBE请求，读取响应，并将其输出到控制台。您可以在此基础上构建更复杂的RTSP客户端。
