How to capture video from a video capture card using C#?

Question

Iron

Good day, I ran into a problem where to start.
There is a video capture board that has 4 inputs / outputs - BlackMagic DeckLink, you need to somehow display the pictures received from the cameras on the screen and take a screen at any time from each camera, the signal format is SDI 1080p.
Searches on the Internet mostly suggest a solution for webcams, but this method does not really fit, the simplest one was probably with Aforge. There are very few examples of working with DirectShow, with the creation of filters, but as they say, this technology is outdated, and according to the new one - Media Foundation, I did not find anything.
Please tell me where to start, some sensible materials.

Answer 1

and on the new - Media Foundation, did not find anything.

I'm embarrassed to ask, are you looking for something at all?
