对不起，我的英语不好
我正在为 rtsp 通信程序工作
此 RTSP 服务器在我的 SETUP 请求中回复 459 错误(不允许聚合操作)
我不知道这个。
请帮我。我做错了什么？

最佳答案
如果您正在实现自己的 RTSP 客户端，您是否阅读并重新阅读了 RFC 2326: RTSP Spec 和 RFC 4566: SDP Spec ？此外，您似乎正在与 Windows Media Server 集成，因此 MSDN 是另一个不错的起点。
RTSP 协议(protocol)基于 session ，每个 session 都由唯一的 URL 标识。一个 session 总是有一个或多个演示流(例如音频、视频、字幕...)。演示流由附加到 session 本身的 URL 上的附加“a:control=...”后缀标识。
某些命令在 session 级别运行，其他命令与演示流一起工作，某些命令可能执行任一操作。 SETUP 命令仅适用于演示流，因此您将返回错误，因为您正在尝试访问 session 。每个演示流都将在其自己的 RTP 流上结束，它们必须单独设置。
所以在你的情况下，如果你想要视频流，你应该发送:
SETUP rtsp://xxx.xxx.xxx.xxx:554/racecar_300.wmv/video RTSP/1.0
