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