190      - unknown
191    * .. _V4L2-PIX-FMT-Y4:
192
193      - ``V4L2_PIX_FMT_Y4``
194      - 'Y04 '
195      - Old 4-bit greyscale format. Only the most significant 4 bits of
196	each byte are used, the other bits are set to 0.
197    * .. _V4L2-PIX-FMT-Y6:
198
199      - ``V4L2_PIX_FMT_Y6``
200      - 'Y06 '
201      - Old 6-bit greyscale format. Only the most significant 6 bits of
202	each byte are used, the other bits are set to 0.
203    * .. _V4L2-PIX-FMT-S5C-UYVY-JPG:
204
205      - ``V4L2_PIX_FMT_S5C_UYVY_JPG``
206      - 'S5CI'
207      - Two-planar format used by Samsung S5C73MX cameras. The first plane
208	contains interleaved JPEG and UYVY image data, followed by meta
209	data in form of an array of offsets to the UYVY data blocks. The
210	actual pointer array follows immediately the interleaved JPEG/UYVY
211	data, the number of entries in this array equals the height of the
212	UYVY image. Each entry is a 4-byte unsigned integer in big endian
213	order and it's an offset to a single pixel line of the UYVY image.
214	The first plane can start either with JPEG or UYVY data chunk. The
215	size of a single UYVY block equals the UYVY image's width
216	multiplied by 2. The size of a JPEG chunk depends on the image and
217	can vary with each line.
218
219	The second plane, at an offset of 4084 bytes, contains a 4-byte
220	offset to the pointer array in the first plane. This offset is
221	followed by a 4-byte value indicating size of the pointer array.
222	All numbers in the second plane are also in big endian order.
223	Remaining data in the second plane is undefined. The information
224	in the second plane allows to easily find location of the pointer
225	array, which can be different for each frame. The size of the
226	pointer array is constant for given UYVY image height.
227
228	In order to extract UYVY and JPEG frames an application can
229	initially set a data pointer to the start of first plane and then
230	add an offset from the first entry of the pointers table. Such a
231	pointer indicates start of an UYVY image pixel line. Whole UYVY
232	line can be copied to a separate buffer. These steps should be
233	repeated for each line, i.e. the number of entries in the pointer
234	array. Anything what's in between the UYVY lines is JPEG data and
235	should be concatenated to form the JPEG stream.
236    * .. _V4L2-PIX-FMT-MT21C:
237
238      - ``V4L2_PIX_FMT_MT21C``
239      - 'MT21'
240      - Compressed two-planar YVU420 format used by Mediatek MT8173.
241	The compression is lossless.
242	It is an opaque intermediate format and the MDP hardware must be
243	used to convert ``V4L2_PIX_FMT_MT21C`` to ``V4L2_PIX_FMT_NV12M``,
244	``V4L2_PIX_FMT_YUV420M`` or ``V4L2_PIX_FMT_YVU420``.
245    * .. _V4L2-PIX-FMT-SUNXI-TILED-NV12:
246
247      - ``V4L2_PIX_FMT_SUNXI_TILED_NV12``
248      - 'ST12'
249      - Two-planar NV12-based format used by the video engine found on Allwinner
250	(codenamed sunxi) platforms, with 32x32 tiles for the luminance plane
251	and 32x64 tiles for the chrominance plane. The data in each tile is
252	stored in linear order, within the tile bounds. Each tile follows the
253	previous one linearly in memory (from left to right, top to bottom).
254
255	The associated buffer dimensions are aligned to match an integer number
256	of tiles, resulting in 32-aligned resolutions for the luminance plane
257	and 16-aligned resolutions for the chrominance plane (with 2x2
258	subsampling).
