/**

|
* SECTION:element-tiger
|
|
* @title: tiger
|
|
* @see_also: katedec
|
|
*
|
|
* This element decodes and renders Kate streams.
|
|
* [Kate](http://libkate.googlecode.com/) is a free codec for text based data,
|
|
* such as subtitles. Any number of kate streams can be embedded in an Ogg
|
|
* stream.
|
|
*
|
|
* libkate (see above url) and [libtiger](http://libtiger.googlecode.com/)
|
|
* are needed to build this element.
|
|
*
|
|
* ## Example pipeline
|
|
*
|
|
* This pipeline renders a Kate stream on top of a Theora video multiplexed
|
|
* in the same stream:
|
|
* |[
|
|
* gst-launch-1.0 \
|
|
* filesrc location=video.ogg ! oggdemux name=demux \
|
|
* demux. ! queue ! theoradec ! videoconvert ! tiger name=tiger \
|
|
* demux. ! queue ! kateparse ! tiger. \
|
|
* tiger. ! videoconvert ! autovideosink
|
|
* ]|
