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{2.0cm}|p{1.0cm}|p{1.0cm}|p{2.7cm}|p{1.0cm}|p{1.0cm}|p{2.7cm}| .. 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)
