|  |   <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> | ||
