rtsp 格式學習以及如何顯示rtsp資料包

 預設情況下，wireshark并沒有分析資料包的内容，進而判斷是否是rtsp資料包，它是根據端口，預設端口是554，認為是進行rtsp協定會話，是以會在捕獲界面顯示資料包的Protocol協定，如果知道哪些端口也是進行rtsp會話的情況下，可以在菜單欄中選擇分析，點選編碼為，在字段中選擇tcp port 值填寫指定的端口，然後在目前的協定中，選擇RTSP

另外，可以通過滑鼠右鍵選擇追蹤流，點選其中的TCP，檢視RTSP的互動過程

問題：RTSP/1.0 405 Method Not Allowed

主要是在進行OPTIONS指令包封裝的時候，通過wireshark抓包進行編寫，

檢視大緻内容為Request: OPTIONS rtsp:://192.168.1.88 RTSP/1.0\r\n

Method: OPTIONS

URL: rtsp:://192.168.1.88

以為資訊的開頭是Request，實際上這是解析的語句

錯誤：

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：

問題：RTSP/1.0 404 Stream Not Found

主要是在進行DESCRIBE的時候沒有填寫擷取的視訊流資訊

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
