                pOffsetForRefFrame is a pointer representing the offset_for_ref_frame array with num_ref_frames_in_pic_order_cnt_cycle number of elements.
                If pOffsetForRefFrame has nullptr value, then num_ref_frames_in_pic_order_cnt_cycle must also be "0".

                StdVideoEncodeH264WeightTable corresponds to the values produced by pred_weight_table() for the h.264 specification.
                For details, refer to weighted_pred_flag, weighted_bipred_idc, pre_pred_weight_table_src and pred_weight_table().
