Every four consecutive samples are packed into seven +bytes. Each of the first four bytes contain the eight high order bits +of the pixels, and the three following bytes contains the six least +significants bits of each pixel, in the same order. + +Each n-pixel row contains n/2 green samples and n/2 blue or red samples, +with alternating green-red and green-blue rows. They are conventionally +described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example +of one of these formats: + +**Byte Order.** +Each cell is one byte. + + + +.. flat-table:: + :header-rows: 0 + :stub-columns: 0 + :widths: 2 1 1 1 1 1 1 1 + + + - .. row 1 + + - start + 0: + + - B\ :sub:`00high` + + - G\ :sub:`01high` + + - B\ :sub:`02high` + + - G\ :sub:`03high` + + - G\ :sub:`01low bits 1--0`\ (bits 7--6) + B\ :sub:`00low bits 5--0`\ (bits 5--0) + + - R\ :sub:`02low bits 3--0`\ (bits 7--4) + G\ :sub:`01low bits 5--2`\ (bits 3--0) + + - G\ :sub:`03low bits 5--0`\ (bits 7--2) + R\ :sub:`02low bits 5--4`\ (bits 1--0) + + - .. row 2 + + - start + 7: + + - G\ :sub:`00high` + + - R\ :sub:`01high` + + - G\ :sub:`02high` + + - R\ :sub:`03high` + + - R\ :sub:`01low bits 1--0`\ (bits 7--6) + G\ :sub:`00low bits 5--0`\ (bits 5--0) + + - G\ :sub:`02low bits 3--0`\ (bits 7--4) + R\ :sub:`01low bits 5--2`\ (bits 3--0) + + - R\ :sub:`03low bits 5--0`\ (bits 7--2) + G\ :sub:`02low bits 5--4`\ (bits 1--0) + + - .. row 3 + + - start + 14 + + - B\ :sub:`20high` + + - G\ :sub:`21high` + + - B\ :sub:`22high` + + - G\ :sub:`23high` + + - G\ :sub:`21low bits 1--0`\ (bits 7--6) + B\ :sub:`20low bits 5--0`\ (bits 5--0) + + - R\ :sub:`22low bits 3--0`\ (bits 7--4) + G\ :sub:`21low bits 5--2`\ (bits 3--0) + + - G\ :sub:`23low bits 5--0`\ (bits 7--2) + R\ :sub:`22low bits 5--4`\ (bits 1--0) + + - .. row 4 + + - start + 21 + + - G\ :sub:`30high` + + - R\ :sub:`31high` + + - G\ :sub:`32high` + + - R\ :sub:`33high` + + - R\ :sub:`31low bits 1--0`\ (bits 7--6) + G\ :sub:`30low bits 5--0`\ (bits 5--0) + + - G\ :sub:`32low bits 3--0`\ (bits 7--4) + R\ :sub:`31low bits 5--2`\ (bits 3--0) + + - R\ :sub:`33low bits 5--0`\ (bits 7--2) + G\ :sub:`32low bits 5--4`\ (bits 1--0) diff --git a/include/uapi/linux/videodev2.h b/include/uapi/linux/videodev2.h index 600877b..a15e03b 100644 --- a/include/uapi/linux/videodev2.h +++ b/include/uapi/linux/videodev2.h @@ -609,6 +609,11 @@ struct v4l2_pix_format { #define V4L2_PIX_FMT_SGBRG12P v4l2_fourcc('p', 'G', 'C', 'C') #define V4L2_PIX_FMT_SGRBG12P v4l2_fourcc('p', 'g', 'C', 'C') #define V4L2_PIX_FMT_SRGGB12P v4l2_fourcc('p', 'R', 'C', 'C') + /* 14bit raw bayer packed, 7 bytes for every 4 pixels */ +#define V4L2_PIX_FMT_SBGGR14P v4l2_fourcc('p', 'B', 'E', 'E') +#define V4L2_PIX_FMT_SGBRG14P v4l2_fourcc('p', 'G', 'E', 'E') +#define V4L2_PIX_FMT_SGRBG14P v4l2_fourcc('p', 'g', 'E', 'E') +#define V4L2_PIX_FMT_SRGGB14P v4l2_fourcc('p', 'R', 'E', 'E') #define V4L2_PIX_FMT_SBGGR16 v4l2_fourcc('B', 'Y', 'R', '2') /* 16 BGBG..
