The KSDATAFORMAT_WAVEFORMATEX structure provides detailed information about the data format of an audio stream consisting of wave data.
DataFormatSpecifies the general features of the stream's data format. This member is a structure of type KSDATAFORMAT.
WaveFormatExDescribes the wave-specific details of the audio stream's data format. This member contains an initialized WAVEFORMATEX structure.
In response to an input DataRange parameter that specifies a WAVEFORMATEX format (see example in PCM Stream Data Range), the IMiniport::DataRangeIntersection method checks to see if the specified pin supports a compatible WAVEFORMATEX format. If so, the method outputs a KSDATAFORMAT_WAVEFORMATEX structure (see example in PCM Stream Data Format) to the buffer that its ResultantFormat parameter points to.
Note that the WaveFormatEx member of the KSDATAFORMAT_WAVEFORMATEX structure can be extended to include additional format information (for example, a channel configuration mask). For more information, see WAVEFORMATEXTENSIBLE.
