| 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. |
