What is wrong with my rtsp methods? (the server always answers 459)

Sorry for my bad english

I work with rtsp program to communicate

this RTSP server responds to error 459 (aggregation operation is not allowed) in my SETUP request

I have no idea about this.

Please help me. What did I misunderstand?

If you use your own RTSP client, read and re-read RFC 2326: RTSP Spec , and RFC 4566: SDP Specification ? It also seems like you're integrating with Windows Media Server, so MSDN is another good place to start.

RTSP is based on sessions, each of which is identified by a unique URL. A session will always have one or more presentation streams (e.g. audio, video, subtitles ...). Presentation streams are identified by the optional suffix "a: control = ...", which is tied to the URL for the session itself.

Some commands work at the session level, other teams work with presentation streams, some commands can execute one of them. The SETUP command ONLY works with presentation streams, so you are returning an error message because you are trying to access a session. Each presentation stream will work in its own RTP stream, and they must be configured separately.

So, in your case, if you want a video stream, you should send:

 SETUP rtsp://xxx.xxx.xxx.xxx:554/racecar_300.wmv/video RTSP/1.0
