In this quick-and-dirty how-to we’re installing the Blackmagic Intensity Pro 4K alongside a Decklink 4K and configuring them to work with OBS.
1. Install dependencies.

sudo apt install dkms build-essential linux-headers-$(uname -r)
Fedora
sudo dnf install dkms @development-tools kernel-devel
2. Install Desktop video and Mediaexpress from /deb/x86_64/ (Debain) or /rpm/x86_64/ (Fedora).
Debian / Ubuntu
sudo dpkg -i desktopvideo_*.deb desktopvideo-gui_*.deb mediaexpress_*.deb
