+V4L2_PIX_FMT_NV12MT_16X16
+Variation of ``V4L2_PIX_FMT_NV12`` and ``V4L2_PIX_FMT_NV21`` with planes
+non contiguous in memory.
+
+
+Description
+===========
+
+This is a multi-planar, two-plane version of the YUV 4:2:0 format. The
+three components are separated into two sub-images or planes.
+``V4L2_PIX_FMT_NV12M`` differs from ``V4L2_PIX_FMT_NV12`` in that the
+two planes are non-contiguous in memory, i.e. the chroma plane do not
+necessarily immediately follows the luma plane. The luminance data
+occupies the first plane. The Y plane has one byte per pixel. In the
+second plane there is a chrominance data with alternating chroma
+samples. The CbCr plane is the same width, in bytes, as the Y plane (and
+of the image), but is half as tall in pixels. Each CbCr pair belongs to
+four pixels. For example, Cb\ :sub:`0`/Cr\ :sub:`0` belongs to
+Y'\ :sub:`00`, Y'\ :sub:`01`, Y'\ :sub:`10`, Y'\ :sub:`11`.
+``V4L2_PIX_FMT_NV12MT_16X16`` is the tiled version of
+``V4L2_PIX_FMT_NV12M`` with 16x16 macroblock tiles. Here pixels are
+arranged in 16x16 2D tiles and tiles are arranged in linear order in
+memory. ``V4L2_PIX_FMT_NV21M`` is the same as ``V4L2_PIX_FMT_NV12M``
+except the Cb and Cr bytes are swapped, the CrCb plane starts with a Cr
+byte.
+
+``V4L2_PIX_FMT_NV12M`` is intended to be used only in drivers and
+applications that support the multi-planar API, described in
+:ref:`planar-apis`.
+
+If the Y plane has pad bytes after each row, then the CbCr plane has as
+many pad bytes after its rows.
+
+**Byte Order.**
+Each cell is one byte.
