IMemInputPin::Receive

  • Article

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

HRESULT Receive(
  IMediaSample* pSample
);

Parameters

  • pSample
    [in] Pointer to a media sample.

Return Values

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

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
