ANALOGVIDEOINFO
構造体サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。
フィールド
| フィールド | 型 | サイズ | x64 | x86 | 説明 |
|---|---|---|---|---|---|
| rcSource | RECT | 16 | +0 | +0 | ソース映像から切り出す矩形領域(RECT)。 |
| rcTarget | RECT | 16 | +16 | +16 | 出力先で映像を配置する矩形領域(RECT)。 |
| dwActiveWidth | DWORD | 4 | +32 | +32 | アナログ映像の有効表示幅。単位はピクセル。 |
| dwActiveHeight | DWORD | 4 | +36 | +36 | アナログ映像の有効表示高さ。単位はピクセル。 |
| AvgTimePerFrame | LONGLONG | 8 | +40 | +40 | 1フレームあたりの平均表示時間。単位は100ナノ秒。 |

}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)
; ANALOGVIDEOINFO 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)
; rcSource : RECT (+0, 16byte) varptr(st)+0 を基点に操作(16byte:入れ子/配列)
; rcTarget : RECT (+16, 16byte) varptr(st)+16 を基点に操作(16byte:入れ子/配列)
; dwActiveWidth : DWORD (+32, 4byte) st.8 = 値 / 値 = st.8 (lpoke/lpeek も可)
; dwActiveHeight : DWORD (+36, 4byte) st.9 = 値 / 値 = st.9 (lpoke/lpeek も可)
; AvgTimePerFrame : LONGLONG (+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。
; ※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)。
