RTSP的状态码是可以拓展的,RTSP的应用不需要理解所以的状态码,只要符合一定的规则就可以了。比如客户端收到一个431,但是又不认识它,可以把它当成400来处理。 这几个x00是最基础的,客户端必须要认识的,其他的看需求了。

下面是协议的原文。

RTSP status codes are extensible. RTSP applications are not required to understand the meaning of all registered status codes, though such understanding is obviously desirable. However, applications MUST understand the class of any status code, as indicated by the first digit, and treat any unrecognized response as being equivalent to the x00 status code of that class, with the exception that an unrecognized response MUST NOT be cached. For example, if an unrecognized status code of 431 is received by the client, it can safely assume that there was something wrong with its request and treat the response as if it had received a 400 status code. In such cases, user agents SHOULD present to the user the entity returned with the response, since that entity is likely to include human- readable information which will explain the unusual status.

这里是协议里定义的状态码。
