Usando dos filtros ASFWriter en un gráfico. Uno está haciendo un archivo wmv, Anather es para transmisión en vivo.

Al realizar la transmisión, cuando se cambia el nombre de un archivo, el inicio de la grabación se retrasa durante 3 segundos. así, falta el jefe de un nuevo WMV. Esta preocupado

CÁMARA ------ InfTee Filter --- --- AsfWriter Filter → WMV FIle

Micrófono --- InfTee Filter2 --- --- AsfWriter Filter2 → Transmisión en vivo

→ 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?
