+Multi-planar format structures
+******************************
+
+The :ref:`struct v4l2_plane_pix_format <v4l2-plane-pix-format>` structures define size
+and layout for each of the planes in a multi-planar format. The
+:ref:`struct v4l2_pix_format_mplane <v4l2-pix-format-mplane>` structure contains
+information common to all planes (such as image width and height) and an
+array of :ref:`struct v4l2_plane_pix_format <v4l2-plane-pix-format>` structures,
+describing all planes of that format.

+       -  __u32
+
+       -  ``bytesperline``
