rtsp客户端不应答服务器

Question

I'm writing a RTSP server. When I wait for header from client my server receives:

OPTIONS rtsp://192.168.1.147:55555 RTSP/1.0
CSeq: 2
User-Agent: LibVLC/2.0.1 (LIVE555 Streaming Media v2011.12.23)

readLine() in this place returns null. then I'm sending :

bw.write("RTSP/1.0 200 OK" + CRLF);
bw.write("Supported: play.basic, con.persistent");
bw.write("CSeq: " + RTSPSeqNb + CRLF);
bw.write("Session: " + RTSP_ID + CRLF);
bw.write("Public: SETUP, PLAY, TEARDOWN" + CRLF+CRLF);
bw.flush();

Where CRLF = "\\r\\n" But there is no any response. My question: WHY?

Answer 1

Did you forget to append CRLF to the second line before CSeq ? Then lots of networking "why" questions could be answered with wireshark .
