Cool, alpha support could really open up some exciting possibilities.
We’re working on a Virtual Studio solution using UE4 and I think we could use Lightact to overcome some of the weaknesses with handling video in UE4.
I’m sure Decklink won’t work unless you implement specific support for it. They had some general windows drivers available before, but it’s pretty much abandoned now. Fortunately, the Decklink SDK is freely available and the cheapest Decklink card is just like $145, so it should be quite easy to implement. We’ve been working with a developer to implement a custom ingest application using Decklink and I can put you in contact with him if you want to outsource the work to someone who is used to working with the SDK. Still, I think basic capture and playback should be pretty trivial to implement and we could certainly help you test it in a broadcast environment.
