-V4L2_PIX_FMT_NV21
-Formats with ½ horizontal and vertical chroma resolution, also known as

-chroma samples as opposed to ``V4L2_PIX_FMT_YVU420``
-
-
-Description
-===========
-
-These are two-plane versions of the YUV 4:2:0 format. The three
-components are separated into two sub-images or planes. The Y plane is
-first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_NV12``, a
-combined CbCr plane immediately follows the Y plane in memory. 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_NV21`` is
-the same except the Cb and Cr bytes are swapped, the CrCb plane starts
-with a Cr byte.
-
-If the Y plane has pad bytes after each row, then the CbCr plane has as
-many pad bytes after its rows.

-

-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

-

-
-Width of the buffer has to be aligned to the multiple of 128, and height

-The requirement that width is multiple of 128 is implemented because,

+******************
+Planar YUV formats
+******************
+
+Planar formats split luma and chroma data in separate memory regions. They
+exist in two variants:
+
+- Semi-planar formats use two planes. The first plane is the luma plane and
+ stores the Y components. The second plane is the chroma plane and stores the
+ Cb and Cr components interleaved.
+
+- Fully planar formats use three planes to store the Y, Cb and Cr components
+ separately.
+
+Within a plane, components are stored in pixel order, which may be linear or
+tiled. Padding may be supported at the end of the lines, and the line stride of
+the chroma planes may be constrained by the line stride of the luma plane.
+
+Some planar formats allow planes to be placed in independent memory locations.
+They are identified by an 'M' suffix in their name (such as in
+``V4L2_PIX_FMT_NV12M``). Those formats are intended to be used only in drivers
+and applications that support the multi-planar API, described in
+:ref:`planar-apis`. Unless explicitly documented as supporting non-contiguous
+planes, formats require the planes to follow each other immediately in memory.
+
+
+Semi-Planar YUV Formats
+=======================
+
+These formats are commonly referred to as NV formats (NV12, NV16, ...). They
+use two planes, and store the luma components in the first plane and the chroma
+components in the second plane. The Cb and Cr components are interleaved in the
+chroma plane, with Cb and Cr always stored in pairs. The chroma order is
+exposed as different formats.
+
+For memory contiguous formats, the number of padding pixels at the end of the
+chroma lines is identical to the padding of the luma lines. Without horizontal
+subsampling, the chroma line stride (in bytes) is thus equal to twice the luma
+line stride. With horizontal subsampling by 2, the chroma line stride is equal
+to the luma line stride. Vertical subsampling doesn't affect the line stride.
+
+For non-contiguous formats, no constraints are enforced by the format on the
+relationship between the luma and chroma line padding and stride.
+
+All components are stored with the same number of bits per component.

+NV12MT and MV12MT_16X16
+-----------------------
+
+Semi-planar YUV 4:2:0 formats, using macroblock tiling. The chroma plane is
+subsampled by 2 in each direction. Chroma lines contain half the number of
+pixels and the same number of bytes as luma lines, and the chroma plane
+contains half the number of lines of the luma plane.
+
+``V4L2_PIX_FMT_NV12MT_16X16`` stores pixel in 2D 16x16 macroblocks, and stores
+macroblocks linearly in memory. The line stride and image height must be
+aligned to a multiple of 16. The layouts of the luma and chroma planes are
+identical.
+
+``V4L2_PIX_FMT_NV12MT`` stores pixels in 2D 64x32 macroblocks, and stores 2x2
+groups of macroblocks in Z-order in memory, alternating Z and mirrored Z shapes
+horizontally. The line stride must be a multiple of 128 pixels to ensure an
+integer number of Z shapes. The image height must be a multiple of 32 pixels.
+If the vertical resolution is an odd number of macroblocks, the last row of
+macroblocks is stored in linear order. The layouts of the luma and chroma
+planes are identical.

Semi-planar pixel formats are documented in separate files. This duplicates information, as those formats share comon traits. Consolidate them in a single file and summarize their descriptions in a single table.
