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)
; D3D11_VIDEO_PROCESSOR_CONTENT_DESC サイズ: 40 バイト(x64)
dim st, 10    ; 4byte整数×10(構造体サイズ 40 / 4 切り上げ)
; InputFrameFormat : D3D11_VIDEO_FRAME_FORMAT (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; InputFrameRate : DXGI_RATIONAL (+4, 8byte)  varptr(st)+4 を基点に操作(8byte:入れ子/配列)
; InputWidth : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; InputHeight : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; OutputFrameRate : DXGI_RATIONAL (+20, 8byte)  varptr(st)+20 を基点に操作(8byte:入れ子/配列)
; OutputWidth : DWORD (+28, 4byte)  st.7 = 値  /  値 = st.7   (lpoke/lpeek も可)
; OutputHeight : DWORD (+32, 4byte)  st.8 = 値  /  値 = st.8   (lpoke/lpeek も可)
; Usage : D3D11_VIDEO_USAGE (+36, 4byte)  st.9 = 値  /  値 = st.9   (lpoke/lpeek も可)
; ※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)。
