| 11 | This interface has been be suspended from the V4L2 API implemented |
| 12 | in Linux 2.6 until we have more experience with effect device |
| 13 | interfaces. |
| 14 | |
| 15 | A V4L2 video effect device can do image effects, filtering, or combine |
| 16 | two or more images or image streams. For example video transitions or |
| 17 | wipes. Applications send data to be processed and receive the result |
| 18 | data either with :ref:`read() <func-read>` and |
| 19 | :ref:`write() <func-write>` functions, or through the streaming I/O |
| 20 | mechanism. |
