Initializes the object's data, for objects - splitter or reader makes opening files and the initial parsing.
HRESULT Init()
Returns:
S_OK AVObject successfully initialized E_FAIL Source file not found or other failure.
Sample
//--------------------------------- // Create MXF Reader object CComPtr<IAVObject> spReader; HRESULT hr = Create_MXFReader(&spReader); if (hr != S_OK) return hr; //--------------------------------- // Query IAVProperties interface CComQIPtr<IAVProperties> spProps(spReader); ATLASSERT(spProps != NULL); //--------------------------------- // Set filename hr = spProps->PropsSet(L"source", L"file.mxf"); if(hr != S_OK) return hr; //--------------------------------- // Init Object hr = spReader->Init(); if(hr != S_OK) return hr;
