IMediaObject::GetInputStatus (Windows Embedded CE 6.0)

1/6/2010

This method queries whether an input stream can accept more input data.

Syntax

HRESULT GetInputStatus(
  DWORD dwInputStreamIndex,
  DWORD* dwFlags
);

Parameters

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

• dwFlags
  [out] Pointer to a variable that receives either zero or DMO_INPUT_STATUSF_ACCEPT_DATA.

Return Value

Returns an HRESULT value. Possible values include the following.

Value	Description
S_OK	Success
DMO_E_INVALIDSTREAMINDEX	Invalid stream index

Remarks

If the input stream will accept more data, the method returns the DMO_INPUT_STATUSF_ACCEPT_DATA flag in the dwFlags parameter. Otherwise, it sets this parameter to zero.

If the stream will accept more data, the application can call the IMediaObject::ProcessInput method.

The status of an input stream can change only as the result of one of the following method calls:

• IMediaObject::Discontinuity
• IMediaObject::Flush
• IMediaObject::ProcessInput
• IMediaObject::ProcessOutput

Requirements

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