There are several notes and warning mesages in the middle of the media docbook. Use the ReST tags for that, as it makes them visually better and hightlights them. While here, modify a few ones to make them clearer. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

Effect Devices Interface
|
|
************************
|
|
|
|
.. note::
|
|
This interface has been be suspended from the V4L2 API.
|
|
The implementation for such effects should be done
|
|
via mem2mem devices.
|
|
|
|
A V4L2 video effect device can do image effects, filtering, or combine
|
|
two or more images or image streams. For example video transitions or
|
|
wipes. Applications send data to be processed and receive the result
|
|
data either with :ref:`read() <func-read>` and
|
|
:ref:`write() <func-write>` functions, or through the streaming I/O
|
|
mechanism.
