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.

Invalid argument. |

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.
