You can use the PKGBUILD in this commit (https://aur.archlinux.org/cgit/aur.git/commit/?h=decklink&id=e63fc9d6265e1782d8e661bbc5a3750df5408ccc), it will build the package for version 1.14.1.
About the error you got earlier, it looks like Blackmagicdesign updated the upstream file without notice. I tried this new file but it does not solve our problem of undetected card.
Sorry I don't have much time to investigate now.

I finally had time to investigate the issue. It looks like that as of 11.5, the
DesktopVideoHelper.service
has to be running for the capture card to work properly.
