rtsp 格式学习

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
