Gets the buffer requirements and other information for an input stream on this Media Foundation transform (MFT).

Syntax

HRESULT GetInputStreamInfo(
  [in]  DWORD                 dwInputStreamID,
  [out] MFT_INPUT_STREAM_INFO *pStreamInfo
);

Parameters

[in] dwInputStreamID

Input stream identifier. To get the list of stream identifiers, call IMFTransform::GetStreamIDs.

[out] pStreamInfo

Pointer to an MFT_INPUT_STREAM_INFO structure. The method fills the structure with information about the input stream.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code	Description
S_OK	The method succeeded.
MF_E_INVALIDSTREAMNUMBER	Invalid stream identifier.

Remarks

It is valid to call this method before setting the media types. Note that the results of this call can change dynamically after the media type changes and after ProcessInput is called, so you may need to call this method again after either of these occur.

If MFT_UNIQUE_METHOD_NAMES is defined before including mftransform.h, this method is renamed MFTGetInputStreamInfo. See Creating Hybrid DMO/MFT Objects.
