#39 closed defect (fixed)

encoder bug of delta QP

Reported by: h.huang Owned by:
Priority: trivial Milestone: HM-16.6-JEM-4.1
Component: JEM Version: HM-16.6-JEM-4.0
Keywords: delta QP Cc: ksuehring, XiangLi, jvet@…

Description

In TEncCu.cpp line 2935:

m_pcEntropyCoder->encodeQP( rpcTempCU, 0, false );

It should be

m_pcEntropyCoder->encodeQP( rpcTempCU, uiFirstNonZeroPartIdx, false );

When delta QP is on, this bug can cause inaccurate coding of QP in RDO process, thus can affect the RD performance. No impact under CTC.
