Description

The VS2017 compiler emits a warning which is considered as an error at line 480 in Quant.cpp when RExt_HIGH_BIT_DEPTH_SUPPORT is enabled in TypeDef.h

const Intermediate_Int iCoeffQ   = (Intermediate_Int(clipQCoef) * scale) * (1 << leftShift);

The warning says: result of 32-bit shift implicitly converted to 64 bits
I would suggest the following to avoid the warning and be able to compile successfully

const Intermediate_Int iCoeffQ   = (Intermediate_Int(clipQCoef) * scale) * (Intermediate_Int(1) << leftShift);
