Kate is a free codec for text based data, which can also carry images.
|
||||
It is typically used to create overlays on a video.
|
||||
|
||||
libkate, a codec for Kate streams, is required to build this plugin:
|
||||
http://libkate.googlecode.com/
|
||||
|
||||
libtiger, a rendering library for Kate streams, is optional:
|
||||
http://libtiger.googlecode.com/
|
||||
|
||||
The Kate plugin contains various elements to manipulate Kate streams:
|
||||
|
||||
- katedec: decodes Kate streams to text
|
||||
- kateenc: encodes Kate streams from text and SPU images
|
||||
- kateparse: parses Kate streams
|
||||
- katetag: allows changing metadata in Kate streams
|
||||
- tiger: decodes and renders Kate streams using libtiger (needs libtiger)
|
||||
|
||||
More information about Kate can be found at:

|

* The kateparse element will parse the header packets of the Kate
|

* stream and put them as the streamheader in the caps. This is used in the
|
||||
* multifdsink case where you want to stream live kate streams to multiple
|
||||
* clients, each client has to receive the streamheaders first before they can
|
||||
* consume the kate packets.
|
||||
* </para>
|
||||
* <para>
|
||||
* This element also makes sure that the buffers that it pushes out are properly
|
||||
* timestamped and that their offset and offset_end are set. The buffers that
|
||||
* kateparse outputs have all of the metadata that oggmux expects to receive,
|
||||
* which allows you to (for example) remux an ogg/kate file.

* @short_description: retags kate streams
|

*
|
||||
* <refsect2>
|
||||
* <para>
|
||||
* The katetag element can change the tag contained within a raw
|
||||
* kate stream. Specifically, it modifies the comments header packet
|
||||
* of the kate stream, as well as the language and category of the
|
||||
* kate stream.
|
||||
* </para>
|
||||
* <para>
|
||||
* The element will also process the stream as the #kateparse element does
|
||||
* so it can be used when remuxing an Ogg Kate stream, without additional
|
||||
* elements.
|
||||
* </para>
|
||||
* <para>
|
||||
* Applications can set the tags to write using the #GstTagSetter interface.
|
||||
* Tags contained within the kate stream will be picked up
|
||||
* automatically (and merged according to the merge mode set via the tag
|
||||
* setter interface).
|
||||
* </para>
|
||||
* <title>Example pipelines</title>
|
||||
* <para>
|
||||
* This element is only useful with gst-launch for modifying the language
|
||||
* and/or category (which are properties of the stream located in the kate
|
||||
* beginning of stream header), because it does not support setting the tags
|
||||
* on a #GstTagSetter interface. Conceptually, the element will usually be
|
||||
* used like:
|
||||
* <programlisting>
|
||||
* gst-launch -v filesrc location=foo.ogg ! oggdemux ! katetag ! oggmux ! filesink location=bar.ogg
|
||||
* </programlisting>
|
||||
* </para>
|
||||
* <para>
|
||||
* This pipeline will set the language and category of the stream to the
|
||||
* given values:
|
||||
* <programlisting>
|
||||
* gst-launch -v filesrc location=foo.ogg ! oggdemux ! katetag language=pt_BR category=subtitles ! oggmux ! filesink location=bar.ogg
|
||||
* </programlisting>
