| 8 | The V4L2 API was primarily designed for devices exchanging image data | |
| 9 | with applications. The :c:type:`struct v4l2_pix_format` and | |
| 10 | :c:type:`struct v4l2_pix_format_mplane` structures define the | |
| 11 | format and layout of an image in memory. The former is used with the | |
| 12 | single-planar API, while the latter is used with the multi-planar | |
| 13 | version (see :ref:`planar-apis`). Image formats are negotiated with | |
| af4a4d0d | 14 | the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. (The explanations here |
| 5377d91f | 15 | focus on video capturing and output, for overlay frame buffer formats |
| af4a4d0d | 16 | see also :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`.) |
