防止过度消耗内存的参数
Name Meaning maxInitialLineLength The maximum length of the initial line (e.g. "SETUP / RTSP/1.0" or "RTSP/1.0 200 OK") If the length of the initial line exceeds this value, a TooLongFrameException will be raised. maxHeaderSize The maximum length of all headers. If the sum of the length of each header exceeds this value, a TooLongFrameException will be raised. maxContentLength The maximum length of the content. If the content length exceeds this value, a TooLongFrameException will be raised.
