HSP用 定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。

; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)
; D3D12_VIDEO_ENCODER_OUTPUT_METADATA_STATISTICS サイズ: 48 バイト(x64)
dim st, 12    ; 4byte整数×12(構造体サイズ 48 / 4 切り上げ)
; AverageQP : ULONGLONG (+0, 8byte)  qpoke st,0,値 / qpeek(st,0)  ※IronHSPのみ。3.7/3.8は lpoke st,0,下位 : lpoke st,4,上位
; IntraCodingUnitsCount : ULONGLONG (+8, 8byte)  qpoke st,8,値 / qpeek(st,8)  ※IronHSPのみ。3.7/3.8は lpoke st,8,下位 : lpoke st,12,上位
; InterCodingUnitsCount : ULONGLONG (+16, 8byte)  qpoke st,16,値 / qpeek(st,16)  ※IronHSPのみ。3.7/3.8は lpoke st,16,下位 : lpoke st,20,上位
; SkipCodingUnitsCount : ULONGLONG (+24, 8byte)  qpoke st,24,値 / qpeek(st,24)  ※IronHSPのみ。3.7/3.8は lpoke st,24,下位 : lpoke st,28,上位
; AverageMotionEstimationXDirection : ULONGLONG (+32, 8byte)  qpoke st,32,値 / qpeek(st,32)  ※IronHSPのみ。3.7/3.8は lpoke st,32,下位 : lpoke st,36,上位
; AverageMotionEstimationYDirection : ULONGLONG (+40, 8byte)  qpoke st,40,値 / qpeek(st,40)  ※IronHSPのみ。3.7/3.8は lpoke st,40,下位 : lpoke st,44,上位
; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。
; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
