CRendererInputPin::Receive (Compact 2013)
3/26/2014
Returns the next block of data from the stream.
Syntax
HRESULT Receive(
IMediaSample* pMediaSample
);
Parameters
- pMediaSample
Media sample.
Return Value
Returns an HRESULT value.
Remarks
This member function implements the IMemInputPin::Receive method, and it overrides the CBaseInputPin::Receive member 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::SetMediaType to change the pin's media type if the sample's type has changed.
Call the IUnknown::AddRef method if you must hold the returned data block beyond the completion of the CRendererInputPin::Receive member function. If you call AddRef, be sure to call the IUnknown::Release method upon completion of AddRef.
