WMMPEG2VIDEOINFO

構造体

サイズx64: 136 バイト / x86: 136 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	x64	x86	説明
hdr	WMVIDEOINFOHEADER2	112	+0	+0	基本となる映像情報ヘッダ(WMVIDEOINFOHEADER2)。
dwStartTimeCode	DWORD	4	+112	+112	シーケンスの開始タイムコード(GOP)。
cbSequenceHeader	DWORD	4	+116	+116	dwSequenceHeaderに格納されたシーケンスヘッダのバイト数。
dwProfile	DWORD	4	+120	+120	MPEG-2のプロファイルを示す値。
dwLevel	DWORD	4	+124	+124	MPEG-2のレベルを示す値。
dwFlags	DWORD	4	+128	+128	追加情報フラグ。
dwSequenceHeader	DWORD	4	+132	+132	MPEG-2シーケンスヘッダデータ(可変長配列)の先頭。

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。
