| 11 | <para>A V4L2 codec can compress, decompress, transform, or otherwise |
| 12 | convert video data from one format into another format, in memory. |
| 13 | Applications send data to be converted to the driver through a |
| 14 | &func-write; call, and receive the converted data through a |
| 15 | &func-read; call. For efficiency a driver may also support streaming |
| 16 | I/O.</para> |
