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_FEATURE_DATA_VIDEO_DECODE_SUPPORT サイズ: 64 バイト(x64)
dim st, 16    ; 4byte整数×16(構造体サイズ 64 / 4 切り上げ)
; NodeIndex : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; Configuration : D3D12_VIDEO_DECODE_CONFIGURATION (+4, 24byte)  varptr(st)+4 を基点に操作(24byte:入れ子/配列)
; Width : DWORD (+28, 4byte)  st.7 = 値  /  値 = st.7   (lpoke/lpeek も可)
; Height : DWORD (+32, 4byte)  st.8 = 値  /  値 = st.8   (lpoke/lpeek も可)
; DecodeFormat : DXGI_FORMAT (+36, 4byte)  st.9 = 値  /  値 = st.9   (lpoke/lpeek も可)
; FrameRate : DXGI_RATIONAL (+40, 8byte)  varptr(st)+40 を基点に操作(8byte:入れ子/配列)
; BitRate : DWORD (+48, 4byte)  st.12 = 値  /  値 = st.12   (lpoke/lpeek も可)
; SupportFlags : D3D12_VIDEO_DECODE_SUPPORT_FLAGS (+52, 4byte)  st.13 = 値  /  値 = st.13   (lpoke/lpeek も可)
; ConfigurationFlags : D3D12_VIDEO_DECODE_CONFIGURATION_FLAGS (+56, 4byte)  st.14 = 値  /  値 = st.14   (lpoke/lpeek も可)
; DecodeTier : D3D12_VIDEO_DECODE_TIER (+60, 4byte)  st.15 = 値  /  値 = st.15   (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。
