.. 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.
