Hi Mache,
To capture video frames with the DeckLink-SDK you need to subclass the IDeckLinkInputCallback interface. This interface defines the VideoInputFrameArrived callback providing the incoming frame.
A high level overview of the capture process can be found in the DeckLink SDK Manual - section 2.4.1 Capture. Also have a look at the Linux Capture sample which captures and stores out raw video to file.
Can you please provide further detail on the issues you see with VS2017? Have you stepped through debug to determine where the samples are failing?
Regards
Cameron

Does anyone know what Decklink drivers work consistently for this plugin? We get lockups in the driver just using the demo provided with the package. When the driver locks up you have to restart the entire PC. We are using a Decklink Quad card. On top of all that, the device indexes change every time you seat the card in the pc. Has anyone had any luck with or solving any of these issues?
Thanks in advance, Regards,
