Bug in Encode Parameter check

Reported by: ssatavalekar Owned by: ksuehring
Priority: minor Milestone: HM-16.2
Component: HM Version: HM-14.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…


Here the description of error is matching with text from hevc spec "The variable Log2MinTrafoSize is set equal to log2_min_transform_block_size_minus2 + 2. The bitstream shall not contain data that result in Log2MinTrafoSize greater than or equal to MinCbLog2SizeY"

The following code snippet from \source\App\TAppEncoder\TAppEncCfg.cpp

xConfirmPara( ( 1 << m_uiQuadtreeTULog2MinSize ) > ( m_uiMaxCUWidth >> m_uiMaxCUDepth ), "Minimum CU width must be greater than minimum transform size." );
xConfirmPara( ( 1 << m_uiQuadtreeTULog2MinSize ) > ( m_uiMaxCUHeight >> m_uiMaxCUDepth ), "Minimum CU height must be greater than minimum transform size." );

these checks are failing when Minimum CU width/Minimum CU height and minimum transform size are both equal.
