#539 closed defect (fixed)

Deblocking Filter Incorrect when Minimum Transform Size is not 4x4.

Reported by: bheng Owned by:
Priority: minor Milestone: HM-7.1
Component: HM Version: HM-7.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…


Some portions of the LoopFilter code assume that the "BaseUnit" is always 4-pixels. However, this assumption is only true when the minimum transform size is 4x4. With any other minimum transform size, only the first four pixels out of each 8, 16, or 32 pixel edge are actually filtered by the HM software.

The attached patch could be used to fix the issues.
