GUIDs de formato de fluxo do BDA

Um minidriver BDA usa GUIDs de formato de fluxo BDA para especificar os formatos de dados aos quais ele dá suporte. A BDA minidriver assigns these GUIDs to members of a KSDATARANGE structure. The Bdamedia.h header file defines these GUIDs. Os pinos de filtros especificam os intervalos de formatos de dados aos quais dão suporte para se conectar a pinos de outros filtros que também dão suporte a esses intervalos.

Os seguintes GUIDs de fluxo estão disponíveis no BDA:

A BDA minidriver assigns this GUID to the SubFormat member of a KSDATARANGE structure to enable connecting to a pin of a filter that also assigns this sub format.

KSDATAFORMAT_SPECIFIER_BDA_TRANSPORT
