KS_DATARANGE_VIDEO_VBI

構造体
サイズx64: 256 バイト / x86: 256 バイト

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

フィールドサイズx64x86説明

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)
; KS_DATARANGE_VIDEO_VBI サイズ: 256 バイト(x64)
dim st, 64    ; 4byte整数×64(構造体サイズ 256 / 4 切り上げ)
; DataRange : KSDATAFORMAT (+0, 64byte)  varptr(st)+0 を基点に操作(64byte:入れ子/配列)
; bFixedSizeSamples : BOOL (+64, 4byte)  st.16 = 値  /  値 = st.16   (lpoke/lpeek も可)
; bTemporalCompression : BOOL (+68, 4byte)  st.17 = 値  /  値 = st.17   (lpoke/lpeek も可)
; StreamDescriptionFlags : DWORD (+72, 4byte)  st.18 = 値  /  値 = st.18   (lpoke/lpeek も可)
; MemoryAllocationFlags : DWORD (+76, 4byte)  st.19 = 値  /  値 = st.19   (lpoke/lpeek も可)
; ConfigCaps : KS_VIDEO_STREAM_CONFIG_CAPS (+80, 128byte)  varptr(st)+80 を基点に操作(128byte:入れ子/配列)
; VBIInfoHeader : KS_VBIINFOHEADER (+208, 44byte)  varptr(st)+208 を基点に操作(44byte:入れ子/配列)
; ※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。
