All Implemented Interfaces:

OggPayload

public class KateDec
extends Element
implements OggPayload

Katedec is a decoder element for the Kate stream format. See http://wiki.xiph.org/index.php/OggKate for more information. Kate streams may be multiplexed in Ogg. The Katedec element accepts Kate packets (presumably demultiplexed by an Ogg demuxer element) on its sink, and generates Kate events on its source. Kate events are Kate specific structures, which may then be interpreted by a renderer.
