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