#515 closed defect (fixed)

QP adaptation fails when minimum transform size is not 4x4

Reported by: bheng Owned by:

Component: HM Version: HM-6.2
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…


The number of partitions in the delta-QP region width, as calculated below, is only correct when the partition width is 4 pixels. This is only true if the minimum transform size is 4x4.

UInt uiNumPartInQpMinCUWidth = getSlice()->getPPS()->getMinCuDQPSize()>>2;

The attached patch can be used to fix this issue.
