IMemInputPin::Receive (Windows Embedded CE 6.0)

1/6/2010

This method receives the next block of data from the stream.

Syntax

HRESULT Receive(
  IMediaSample* pSample
);

Parameters

  • pSample
    [in] Pointer to a media sample.

Return Value

Returns an HRESULT value that depends on the implementation.

HRESULT can be one of the following standard constants, or other values not listed.

Value Description

E_FAIL

Failure.

E_POINTER

Null pointer argument.

E_INVALIDARG

Invalid argument.

E_NOTIMPL

Method is not supported.

S_OK or NOERROR

Success.

Remarks

This is a blocking synchronous call.

Typically, no blocking occurs, but if a filter cannot process the sample immediately it may use the calling application's thread to wait until it can.

Use the IUnknown::AddRef method if you need to hold the returned data block beyond the completion of the IMemInputPin::Receive method.

If you use AddRef, be sure to use IUnknown::Release when done with it.

Requirements

Windows Embedded CE Windows CE 2.12 and later
Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
For more information, see Setting Up the Build Environment, Version 2.12 requires DXPAK 1.0 or later
