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.
