#29 closed defect (fixed)

Mismatch between estLastSignificantPositionBit and codeLastSignificantXY

Reported by: tpoirier Owned by:
Priority: minor Milestone: HM-16.6-JEM-3.2
Component: JEM Version: HM-16.6-JEM-3.1
Keywords: Cc: ksuehring, XiangLi, jvet@…


In TEncSbac::estLastSignificantPositionBit, width and height are not swapped if coefficient scanning is vertical as in TEncSbac::codeLastSignificantXY.
It leads to a wrong rate estimation in xRateDistOptQuant due to the uninitialization of m_pcEstBitsSbac->lastXBits (lastYBits).
The following patch should solve the problem.
