Every two consecutive samples are packed into three +bytes. Each of the first two bytes contain the 8 high order bits of +the pixels, and the third byte contains the four 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 a small V4L2_PIX_FMT_SBGGR12P image: + +**Byte Order.** +Each cell is one byte. + +.. tabularcolumns:: |p{2.2cm}|p{1.2cm}|p{1.2cm}|p{3.1cm}|p{1.2cm}|p{1.2cm}|p{3.1cm}| + + +.. flat-table:: + :header-rows: 0 + :stub-columns: 0 + :widths: 2 1 1 1 1 1 1 + + + - - start + 0: + - B\ :sub:`00high` + - G\ :sub:`01high` + - G\ :sub:`01low`\ (bits 7--4) + + B\ :sub:`00low`\ (bits 3--0) + - B\ :sub:`02high` + - G\ :sub:`03high` + - G\ :sub:`03low`\ (bits 7--4) + + B\ :sub:`02low`\ (bits 3--0) + + - - start + 6: + - G\ :sub:`10high` + - R\ :sub:`11high` + - R\ :sub:`11low`\ (bits 7--4) + + G\ :sub:`10low`\ (bits 3--0) + - G\ :sub:`12high` + - R\ :sub:`13high` + - R\ :sub:`13low`\ (bits 3--2) + + G\ :sub:`12low`\ (bits 3--0) + - - start + 12: + - B\ :sub:`20high` + - G\ :sub:`21high` + - G\ :sub:`21low`\ (bits 7--4) + + B\ :sub:`20low`\ (bits 3--0) + - B\ :sub:`22high` + - G\ :sub:`23high` + - G\ :sub:`23low`\ (bits 7--4) + + B\ :sub:`22low`\ (bits 3--0) + - - start + 18: + - G\ :sub:`30high` + - R\ :sub:`31high` + - R\ :sub:`31low`\ (bits 7--4) + + G\ :sub:`30low`\ (bits 3--0) + - G\ :sub:`32high` + - R\ :sub:`33high` + - R\ :sub:`33low`\ (bits 3--2) + + G\ :sub:`32low`\ (bits 3--0) |
