構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 20 バイト / x86: 20 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

フィールド型サイズx64x86説明
ReconstructedPictureResourceIndexDWORD4+0+0再構成ピクチャリソース配列内での当該参照ピクチャのインデックスを示す。
IsRefUsedByCurrentPicBOOL4+4+4当該参照ピクチャが現在のピクチャから実際に参照されるかを示す。
IsLongTermReferenceBOOL4+8+8当該ピクチャが長期参照か否かを示す。TRUEで長期参照。
PictureOrderCountNumberDWORD4+12+12当該参照ピクチャのピクチャ順序カウント(POC)値を示す。
TemporalLayerIndexDWORD4+16+16当該参照ピクチャが属する時間階層のインデックスを示す。

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_ENCODER_REFERENCE_PICTURE_DESCRIPTOR_HEVC サイズ: 20 バイト(x64)
dim st, 5    ; 4byte整数×5(構造体サイズ 20 / 4 切り上げ)
; ReconstructedPictureResourceIndex : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; IsRefUsedByCurrentPic : BOOL (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; IsLongTermReference : BOOL (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; PictureOrderCountNumber : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; TemporalLayerIndex : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (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。
