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
