Verwenden von zwei ASFWriter-Filtern in einem Diagramm. Anather erstellt eine WMV-Datei für das Live-Streaming.

Streaming durchführen, Beim Ändern eines Dateinamens ist der Aufnahmestart für 3 Sekunden überfällig. also der kopf eines neuen wmv fehlt. Es ist beunruhigt.

KAMERA ------ InfTee Filter --- --- AsfWriter Filter → WMV-Datei

                        X

Mikrofon --- InfTee Filter2 --- --- AsfWriter Filter2 → Live-Streaming

void RecStart()

        ...

→ 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?
