Returns the next block of data from the stream.

Syntax 

HRESULT Receive(
  IMediaSample* 
pMediaSample 
);

Parameters

pMediaSample

Media sample.

Return Value

Returns an HRESULTvalue.

Remarks

This member function implements the IMemInputPin::Receivemethod, and it overrides the CBaseInputPin::Receivemember function, which it calls to verify formats.

This is a blocking synchronous member function. It blocks and waits until it is time for the sample to be rendered.

It calls CBaseRenderer::Receive, which does the blocking.

Because only one sample is ever outstanding, this member function checks the media type and calls CRendererInputPin::SetMediaTypeto change the pin's media type if the sample's type has changed.

Call the IUnknown::AddRefmethod if you must hold the returned data block beyond the completion of the CRendererInputPin::Receivemember function. If you call AddRef, be sure to call the IUnknown::Releasemethod upon completion of AddRef.
