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_PROCESS_OUTPUT_STREAM_DESC サイズ: 44 バイト(x64)
dim st, 11    ; 4byte整数×11(構造体サイズ 44 / 4 切り上げ)
; Format : DXGI_FORMAT (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; ColorSpace : DXGI_COLOR_SPACE_TYPE (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; AlphaFillMode : D3D12_VIDEO_PROCESS_ALPHA_FILL_MODE (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; AlphaFillModeSourceStreamIndex : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; BackgroundColor : FLOAT (+16, 16byte)  varptr(st)+16 を基点に操作(16byte:入れ子/配列)
; FrameRate : DXGI_RATIONAL (+32, 8byte)  varptr(st)+32 を基点に操作(8byte:入れ子/配列)
; EnableStereo : BOOL (+40, 4byte)  st.10 = 値  /  値 = st.10   (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)。
