* .. _V4L2-PIX-FMT-S5C-UYVY-JPG:
- ``V4L2_PIX_FMT_S5C_UYVY_JPG``
- 'S5CI'
- Two-planar format used by Samsung S5C73MX cameras. The first plane
contains interleaved JPEG and UYVY image data, followed by meta
data in form of an array of offsets to the UYVY data blocks. The
actual pointer array follows immediately the interleaved JPEG/UYVY
data, the number of entries in this array equals the height of the
UYVY image. Each entry is a 4-byte unsigned integer in big endian
order and it's an offset to a single pixel line of the UYVY image.
The first plane can start either with JPEG or UYVY data chunk. The
size of a single UYVY block equals the UYVY image's width
multiplied by 2. The size of a JPEG chunk depends on the image and
can vary with each line.
The second plane, at an offset of 4084 bytes, contains a 4-byte
offset to the pointer array in the first plane. This offset is
followed by a 4-byte value indicating size of the pointer array.
All numbers in the second plane are also in big endian order.
Remaining data in the second plane is undefined. The information
in the second plane allows to easily find location of the pointer
array, which can be different for each frame. The size of the
pointer array is constant for given UYVY image height.
In order to extract UYVY and JPEG frames an application can
initially set a data pointer to the start of first plane and then
add an offset from the first entry of the pointers table. Such a
pointer indicates start of an UYVY image pixel line. Whole UYVY
line can be copied to a separate buffer. These steps should be
repeated for each line, i.e. the number of entries in the pointer
array. Anything what's in between the UYVY lines is JPEG data and
should be concatenated to form the JPEG stream.
* .. _V4L2-PIX-FMT-MT21C:
- ``V4L2_PIX_FMT_MT21C``
- 'MT21'
- Compressed two-planar YVU420 format used by Mediatek MT8173, MT8192,
MT8195 and more. The compression is lossless. This format have
similitude with ``V4L2_PIX_FMT_MM21`` in term of alignment and tiling.
It remains an opaque intermediate format and the MDP hardware must be
used to convert ``V4L2_PIX_FMT_MT21C`` to ``V4L2_PIX_FMT_NV12M``,
``V4L2_PIX_FMT_YUV420M`` or ``V4L2_PIX_FMT_YVU420``.
* .. _V4L2-PIX-FMT-QC08C:
- ``V4L2_PIX_FMT_QC08C``
- 'QC08C'
- Compressed Macro-tile 8-Bit YUV420 format used by Qualcomm platforms.
It is an opaque intermediate format. The used compression is lossless
and it is used by various multimedia hardware blocks like GPU, display
controllers, ISP and video accelerators.
It contains four planes for progressive video and eight planes for
interlaced video.
* .. _V4L2-PIX-FMT-QC10C:
- ``V4L2_PIX_FMT_QC10C``
- 'QC10C'
- Compressed Macro-tile 10-Bit YUV420 format used by Qualcomm platforms.
It is an opaque intermediate format. The used compression is lossless
and it is used by various multimedia hardware blocks like GPU, display
controllers, ISP and video accelerators.
It contains four planes for progressive video.
