14 | A V4L2 video effect device can do image effects, filtering, or combine | |
15 | two or more images or image streams. For example video transitions or | |
16 | wipes. Applications send data to be processed and receive the result | |
17 | data either with :ref:`read() <func-read>` and | |
18 | :ref:`write() <func-write>` functions, or through the streaming I/O | |
19 | mechanism. | |
