PSCALY_F
Primary Image Vertical Down-scaling Factor
A 6-bit value specifies the vertical down-scaling factor. The scaling factor is equal to
(1+SCALY_F). For example, if SCALY_F = 3, the image will shrink 4 times in vertical
direction.
Note:
For planar format encode mode, SCALY_F can be any value from 0 to 63. For
planar format decode mode, the value of SCALY_F can only be 0, 1, 3, 7, i.e. scaling-down
1/1, 1/2, 1/4 and 1/8.
For packet format, SCALY_F is reserved.
