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 HRESULTvalue that depends on the implementation. HRESULTcan be one of the following standard constants, or other values not listed.
E_FAIL Failure. E_POINTER Null pointer argument. E_INVALIDARG Invalid argument. E_NOTIMPL Method isn't 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::AddRefmethod if you need to hold the returned data block beyond the completion of the IMemInputPin::Receivemethod. If you use AddRef, be sure to use IUnknown::Releasewhen done with it.
