+Image Formats
+#############
+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>`.)
