IAMFilterMiscFlags Interface

The IAMFilterMiscFlags interface specifies whether a filter's data stream is source data or data being rendered.

IAMFilterMiscFlags is implemented by Microsoft® DirectShow®.

You can use IAMFilterMiscFlags as a definitive way to determine which filters are being used as renderer filters and, thus, how many EC_COMPLETE notifications to expect before a movie is done.

IAMFilterMiscFlags::GetMiscFlags

IAMFilterMiscFlags Interface

Retrieves the filter status flag.

Syntax

ULONG GetMiscFlags(void);

Return Value

Returns AM_FILTER_MISC_FLAGS_IS_RENDERED if the stream is being rendered. Returns AM_FILTER_MISC_FLAGS_IS_SOURCE if the stream is the source data. Both flags are defined in the AM_FILTER_MISC_FLAGS enumeration. If the filter supports IMediaSeeking and renders some streams, then AM_FILTER_MISC_FLAGS_IS_RENDERER should be returned.
