Mauro Carvalho Chehab 8e080c2e6c V4L/DVB (12761): DocBook: add media API specs
The V4L and DVB API's are there for a long time. however, up to now,
no efforts were done to merge them to kernel DocBook.

This patch adds the current versions of the specs as an unique compendium.

<para>A V4L2 codec can compress, decompress, transform, or otherwise
convert video data from one format into another format, in memory.
Applications send data to be converted to the driver through a
&func-write; call, and receive the converted data through a
&func-read; call. For efficiency a driver may also support streaming
I/O.</para>
