Same Problem over here.
I do have a Decklink 4k capture Card, but in 4:2:2 HDSDI 1080i50, I do only get black images by capturing via EmguCV library (built my own capture software).
I also do have access to a 4k Extreme Card (which doesn`t belong to me) and there, the code works perfect without any issues.
My Decklink 4k Driver is 10.1.1 or newer (tested all of it), while the driver for the Decklink 4k Extreme is the 9.8.0.0 from Oct 2013, so it is a really old one. But we do not want to update it now, because if we do face the same problem then, it will be a big problem for your workflow.
Anybody with a workaround out there?
Oh, by the way in Media Express everything works like a charm, so the card itself shouldn`t be the problem. It seems that it has something to do with the WDM drivers.
Any feedback from BM officials?
