グラフで 2 つの ASFWriter フィルターを使用します。1 つは wmv ファイルを作成し、もう 1 つはライブ ストリーミング用です。
ストリーミング中、ファイル名変更時、録画開始が3秒遅れる。そのため、New WMV の先頭が欠落しています。困ったものです。
CAMERA ------ InfTee Filter --- --- AsfWriter Filter → WMV FILE

→ I think ... In order to wait for starting of streaming,
it is missing for 3 seconds in head of New WMV File.
Are there any measures?
