2054f38fcaSMauro Carvalho ChehabThese four pixel formats are raw sRGB / Bayer formats with 8 bits per
2154f38fcaSMauro Carvalho Chehabsample. Each sample is stored in a byte. Each n-pixel row contains n/2
2254f38fcaSMauro Carvalho Chehabgreen samples and n/2 blue or red samples, with alternating red and
2354f38fcaSMauro Carvalho Chehabblue rows. They are conventionally described as GRGR... BGBG...,
2454f38fcaSMauro Carvalho ChehabRGRG... GBGB..., etc. Below is an example of a small V4L2_PIX_FMT_SBGGR8 image:
