The V4L2_PIX_FMT_S5C_UYVY_JPG is a single-planar image format generated
by S5C73M3 camera. The image data consist of interleaved JPEG compressed
data and raw UYVY data and the meta data appended at the end.
The meta-data is a list of offsets to UYVY data blocks of fixed size, which
may be followed by a JPEG data chunk. Whether the JPEG chunk is present
between two subsequent VYUY blocks can be figured out from the difference
between two offset values.
All numbers are 4 byte unsigned integers.
