All Implemented Interfaces:

ChannelHandler

public class RtspDecoder
extends HttpObjectDecoder

Decodes io.netty5.buffer.ByteBufs into RTSP messages represented in HttpMessages.

Parameters that prevents excessive memory consumption

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.
