Using Telestream Wirecast version 8 with your Dacast Account. There are two methods to set up Wirecast with your Dacast account. The first method is a manual configuration, and the second method is based on the Dacast integration within Wirecast. Manual configuration has the advantage of working with all sorts of different custom RTMP encoders. Video transcoding, streaming, capture, screen recording.

Wirecast Instructions
I'll try to be as complete as possible with the specs, but this post is mostly about a hypothetical build.
We were thinking of doing setup like Mac->Declink Duo 2 in a Sonnet Thunderbolt 3 Expansion Box->LiveU BackPack->Wowza->CDN.
So we'd use 3 cameras as inputs to Wirecast, which seems to be working in Wirecast 8 I gather from other threads and research. The Decklink Duo 2 is still PCIe Gen 2 x4, so max 16GB/s which Thunderbolt 3 can easily handle.
My biggest question as of right now is this: can you output the Wirecast video on this card? I know you can configure the SDI I/O however you'd like on BlackMagic's side of things, but does Wirecast see it as an output? Can I also embed the audio in that output from Wirecast? Or would I have to get some SDI + audio embedder to combine something like my headphone out into the video signal?
The mac we'd use to test it now is a Mac Pro 2013, 2.7GHz model running High Sierra 10.13.1 and Wirecast Pro 6.0.8. Although we'll most likely be upgrading everything at once so it will end up being an iMac Pro with Wirecast 8.
If this doesn't seem possible on a Mac is it possible on Windows? We were contemplating building an arguably much cheaper Windows machine to host the card, but were worried about portability since we'd have to take the tower and monitor.
