I try to create copy of IMediaSample from one of my two input pins of my Filter.

Function

HRESULT hr = m_pAllocator->GetBuffer(&pMediaSample->pOUTSBuffer_1,&start_time, &end_time,AM_GBF_NOTASYNCPOINT);

returns 0x80040211.

When using this function, Graph Edit hangs.

I decided to use

pMediaSample->pINSSBuffer_1->QueryInterface(IID_IMediaSample,(void**)&pMediaSample->pOUTSBuffer_1);

But i do not know, if QueryInterface creates new instance of desired object.
