Description
QP prediction from the top CTU (at left edge) is being used across slice/tile/brick boundaries. The following if statement should include an additional isSameSliceAndTile check before using the top CTU QP.
if ( !cu.blocks[cu.chType].x && !( cu.blocks[cu.chType].y & ( cs.pcv->maxCUHeightMask >> getChannelTypeScaleY( cu.chType, cu.chromaFormat ) ) ) && ( cs.getCU( cu.blocks[cu.chType].pos().offset( 0, -1 ), cu.chType) != NULL ) )
{
return ( ( cs.getCU( cu.blocks[cu.chType].pos().offset( 0, -1 ), cu.chType ) )->qp );
}
