Doesn't work with "Blackmagic Device" source (Decklink card)

[Fred-DTV]

First off: Thanks a lot for the amazing plugin! It made a long wished for stream project of ours possible.

I've been using it successfully with an Atem Mini so far, but for another project I have to use a Decklink card now.
Unfortunately It doesn't work. The replay source won't load the video from the buffer.

Any idea what could cause this?

Edit: Interestingly enough it works with the decklink card when added as a regular "Video Capture Device"
So after all it is acutally not a big issue :D Sorry for the hustle
