Blackmagic Forum

Hi,

I used Blackmagic Desktop Video Windows 10.9.11 driver.

I used also Blackmagic DeckLink SDK 10.9.11 and the new interface IKsDeckLink.

The notes are:
* This interface contains methods shared between the capture and render
* filters. It is not accessed directly, but through the IKsDeckLinkCapture and
* IKsDeckLinkRender interfaces.

But when I used

JIF(CoCreateInstance(CLSID_DecklinkVideoRenderFilter, NULL, CLSCTX_INPROC_SERVER, IID_IBaseFilter, (void **)&pDeckVidRender));

IKsDeckLinkRender * pKsDeckLink = NULL;
if (pDeckVidRender->QueryInterface(IID_IKsDeckLinkRender, (void **)&pKsDeckLink) == S_OK)
...
occurs a NO_INTERFACE error.
Where am I wronging?

Thanks
Mariella
