The V4L2_PIX_FMT_S5C_UYVY_JPG is a two-plane image format used by
Samsung S5C73M3 camera. The first plane contains interleaved UYVY
and JPEG data, followed by meta-data in form of offsets to the UYVU
data blocks.
The second plane contains additional meta-data needed for extracting
JPEG and UYVY data stream from the first plane, in particular an
offset to the first entry of an array of data offsets in the first
plane. The offsets are expressed as 4-byte unsigned integers.
