Hi Kamaraj,
From your description, I believe you have 2 applications attempting to access the IDeckLinkInput object interface. Because your preview application already has enabled input, then FFmpeg cannot also access the input at the same time, hence why call to IDeckLinkInput::EnableVideoInput method fails.
You should keep your preview and capture in a single application, or if you application allows for, disable the input on your preview application before starting FFmpeg capture.
