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 サイズ: 72 バイト(x64)
dim st, 18    ; 4byte整数×18(構造体サイズ 72 / 4 切り上げ)
; EncodeErrorFlags : 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
; EncodeStats : D3D12_VIDEO_ENCODER_OUTPUT_METADATA_STATISTICS (+8, 48byte)  varptr(st)+8 を基点に操作(48byte:入れ子/配列)
; EncodedBitstreamWrittenBytesCount : ULONGLONG (+56, 8byte)  qpoke st,56,値 / qpeek(st,56)  ※IronHSPのみ。3.7/3.8は lpoke st,56,下位 : lpoke st,60,上位
; WrittenSubregionsCount : ULONGLONG (+64, 8byte)  qpoke st,64,値 / qpeek(st,64)  ※IronHSPのみ。3.7/3.8は lpoke st,64,下位 : lpoke st,68,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。
; ※GUID・入れ子構造体はデフォルト型でないため、依存する #defstruct を先に定義(下記に同梱)。
