0: JPEG picture width is a multiple of 16.

1: JPEG picture width is a multiple of 8 pixels but not a multiple of 16 pixels. Can be set to 1 only for JPEG sampling format
0. HW must fill one block of zero pixel data to the right border of the picture.

Input picture sampling format

0: single type, MB 1 block,

1: single type, MB 4 blocks (not supported),

2: three types, MB 6 blocks (4:2:0),

3: three types, MB 4 blocks (4:2:2),

4: three types, MB 3 blocks (4:4:4) (Not supported)

5: three types, MB 4 blocks (4:4:0)

0: No quantization tables. (not supported)

1: One quantization table. Used when picture is single type.

2: Two quantization tables. One for luminance and one for Chrominance. (not supported)

3: Three quantization tables. Each type (Lu, Cr, Cb) has own QP-table.

Base address for tables is defined in “Base address for standard dependent tables” register, offset 0x00a0.

Exact bit of stream start word where decoding can be started.
