Class RTPChannel

java.lang.Object
  de.humatic.dsj.src.rtp.RTPChannel

public class RTPChannel
extends java.lang.Object

RTPChannel represents a single subsession within an rtsp/rtp stream. Channels are setup by either RTP / RTSPSources during stream negotiation / sdp parsing and later on receive payload specific data from the Source or from RTPSink to handle packetizing of sample data. RTPChannels will themselves construct a dedicated RTPHandler object, that knows how to deal with a specific mediatype and its transport via RTP.
Methods in this class are called by the Source or its Filtergraph and are public for package design reasons, application code does not directly use this class.

Constructor Summary

RTPChannel(JSink sink, java.lang.String tID, int pt, int cNr, int inssrc)
Constructs an RTPChannel for outgoing data, used by RTPSink.

RTPChannel(Source src, java.lang.String tID, int pt, int cNr, int flags)
Constructs an RTPChannel for incoming data as used by RTPSource and RTSPSource.
