Class DataSource

java.lang.Object
  javax.media.protocol.DataSource
      javax.media.protocol.PushBufferDataSource
          net.sf.fmj.media.protocol.rtp.DataSource

All Implemented Interfaces:

Controls, Duration

public class DataSource
extends PushBufferDataSource

RTP protocol handler DataSource. Very basic; makes the connection, gets the underlying DataSource, and delegates all calls to the underlying DataSource. TODO: support the full URL format: "rtp://address:port[:ssrc]/content-type/[ttl]" address is an IP address, port is an integer port number, and content-type is a string such as video or audio. The SSRC (Synchronizing Source) and TTL (Time to Live) fields are optional. TODO: the dimensions of the format (if video) are not known until a frame arrives. We probably need to wrap ((PushBufferDataSource) dataSource).getStreams(); to somehow get the first frame if it is video, and determine the format, and have our wrapper return the full format when queried.
