188c2ecf20Sopenharmony_ci===========
198c2ecf20Sopenharmony_ci
208c2ecf20Sopenharmony_ciThese four pixel formats are raw sRGB / Bayer formats with 14 bits per
218c2ecf20Sopenharmony_cicolour. Each sample is stored in a 16-bit word, with two unused high
228c2ecf20Sopenharmony_cibits filled with zeros. Each n-pixel row contains n/2 green samples
238c2ecf20Sopenharmony_ciand n/2 blue or red samples, with alternating red and blue rows. Bytes
248c2ecf20Sopenharmony_ciare stored in memory in little endian order. They are conventionally
258c2ecf20Sopenharmony_cidescribed as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an
268c2ecf20Sopenharmony_ciexample of a small V4L2_PIX_FMT_SBGGR14 image:
