#543 closed defect (fixed)

Variables are wrongly increased in the spec

Description

In 8.4.5.1,
xPartIdx = xPartIdx + xPartInc
yPartIdx = yPartIdx + yPartInc
are done before invoking the decoding process for each part. So the part with idx=0 will be wrongly skipped.

Recommendation:
The variables should be increased after invoking the decoding process as attached.

Thanks for reporting.

This will be fixed JVET-P2001-vD without moving it:

  • For i = 0..NumIntraSubPartitions − 1, the following applies:
  1. The variables xPartIdx, yPartIdx, and xPartPbIdx are derived as follows:

xPartIdx = i * xPartInc (8‑53)
yPartIdx = i * yPartInc (8‑54)
xPartPbIdx = xPartIdx % pbFactor (8‑55)
