This method retrieves information about an input stream, such as any restrictions on the number of samples per buffer, and whether the stream performs a lookahead on the input data. This information never changes.

Syntax

HRESULT GetInputStreamInfo(
  DWORD dwInputStreamIndex,
  DWORD* pdwFlags
);

Parameters

  • dwInputStreamIndex
    Zero-based index of an input stream on the DMO.

Return Value

Returns an HRESULT value. Possible values include the following.

Value Description

S_OK

Success

DMO_E_INVALIDSTREAMINDEX

Invalid stream index

E_POINTER

NULL pointer argument

Remarks

The DMO_INPUT_STREAMF_HOLDS_BUFFERS flag indicates that the DMO performs a lookahead on the incoming data.

The application must be sure to allocate sufficient buffers for the DMO to process the input. Call the IMediaObject::GetInputSizeInfo method to determine the buffer requirements.

Requirements

Header dmo.h
Library Dmoguid.lib
Windows Embedded CE Windows CE .NET 4.1 and later
Windows Mobile Windows Mobile Version 5.0 and later
