默认情况下,wireshark并没有分析数据包的内容,从而判断是否是rtsp数据包,它是根据端口,默认端口是554,认为是进行rtsp协议会话,所以会在捕获界面显示数据包的Protocol协议,如果知道哪些端口也是进行rtsp会话的情况下,可以在菜单栏中选择分析,点击编码为,在字段中选择tcp port 值填写指定的端口,然后在当前的协议中,选择RTSP
另外,可以通过鼠标右键选择追踪流,点击其中的TCP,查看RTSP的交互过程
问题:RTSP/1.0 405 Method Not Allowed
主要是在进行OPTIONS指令包封装的时候,通过wireshark抓包进行编写,
查看大致内容为Request: OPTIONS rtsp:://192.168.1.88 RTSP/1.0\r\n
Method: OPTIONS
URL: rtsp:://192.168.1.88
以为信息的开头是Request,实际上这是解析的语句
错误:
request_stream << "REQUEST: " <<"OPTIONS " << "rtsp://192.168.0.114 " << "RTSP/1.0\r\n";
request_stream << "CSeq: " << "2\r\n";
request_stream << "User-Agent: " << "LibVLC/2.1.5 (Live555 Streaming Media v2014.0)\r\n\r\n";
正确:
问题:RTSP/1.0 404 Stream Not Found
主要是在进行DESCRIBE的时候没有填写获取的视频流信息
request_stream << "DESCRIBE " << "rtsp://192.168.0.114/smoke.264 " << "RTSP/1.0\r\n";//right
request_stream << "DESCRIBE " << "rtsp://192.168.0.114 " << "RTSP/1.0\r\n";//error
