#1462 closed defect (fixed)

Encoder/decoder mismatch when activating chroma dQP

After fixing #1461, encoder/decoder mismatch show up.
This is caused by several issues:

  • missing call to xCheckChromaQPOffset in xCheckModeSplit (failing to reset chroma-QG's heading non-coded blocks to zero-offset)
  • in xCheckChromaQPOffset, bad reset of chroma-QG's heading non-coded blocks to zero-offset (missing for loop for CUs + bad conditions)
  • missing copy of m_cuChromaQpOffsetIdxPlus1 to cu.chromaQpAdj for GEO modes
