Type Alias VAQMatrixBufferHEVC 

pub type VAQMatrixBufferHEVC = _VAQMatrixBufferHEVC;

\brief HEVC Quantization Matrix Buffer Structure

This structure is sent once per frame, and only when scaling_list_enabled_flag = 1 and scaling_list_data_present_flag = 1. Only when scaling_list_data_present_flag = 1, app still needs to send in this structure. When scaling_list_enabled_flag = 1 and scaling_list_data_present_flag = 0, driver is responsible to generate the default scaling list values.

Matrix entries are in raster scan order which follows HEVC spec.
