Blackmagic / Decklink capture drivers Arch Linux

The Drivers are a 538mb .tar.gz file, Simple Steps:

1. Download the latest drivers from the blackmagic website (10.5.4 at the time of this post), put these in a folder in your home directory, say called "blackmagic".

2. Download the PKGBUILD from the AUR (Download Snapshot on the AUR page for decklink). Extract "PKGBUILD" and "decklink.install" to the folder you made in step 1.

https://aur.archlinux.org/packages/decklink/

3. Get the sha256 checksum of the driver package you downloaded.
In a terminal within the same directory as the downloaded file type:

sha256sum Blackmagic_Desktop_Video_Linux_10.5.4.tar.gz

This will then print out the sha256sum we'll need to put in the PKGBUILD file next:

5. Edit the PKGBUILD file you extracted from the snapshot with your favourite text editor, it's just a normal text file, change the "sha256sum=('checksumhere')" to the new one you got from step 3.

Also change the "source=("/path/to/Black_Magic_blahblah.tar.gz")" to the path to the file you downloaded in step 1.

You'll also need to change the "_dvver=" line to "_dvver=10.5.4a4" and the "_mever=" line to "_mever=3.5a9"

6. ... FINALLY it's time to install the PKGBUILD: Open a terminal in the directory you've been working in and type "makepkg -sri" - this should make an installable arch package and install it.

Or you can then manually install it whenever you like with the command "sudo pacman -U decklink-10.5.4a4-1-x86_64.pkg.tar.xz" obviously changing the command to whatever the generated file name is you just made.

Provided everything was done right it should now be installed.
