KSDATAFORMAT_DSOUND structure

Description

The KSDATAFORMAT_DSOUND structure provides detailed information about a DirectSound audio stream.

Members

`DataFormat`

Specifies the stream's data format. This member is a structure of type KSDATAFORMAT.

`BufferDesc`

Describes the DirectSound buffer. This member is a structure of type KSDSOUND_BUFFERDESC.

Remarks

In response to an input DataRange parameter that specifies a DirectSound format (see example in DirectSound Stream Data Range), the IMiniport::DataRangeIntersection method checks to see if the specified pin supports a compatible DirectSound format. If so, the method outputs a KSDATAFORMAT_DSOUND structure (see example in DirectSound Stream Data Format) to the buffer that its ResultantFormat parameter points to.
