How to install DeckLink 4K Pro on recent Debian 12

Hi,

I got an "old" DeckLink 4K Pro card and want to run it on Linux.
I tried the latest "Blackmagic_Desktop_Video_Linux_12.7.1.tar" and an older version "Blackmagic_Desktop_Video_Linux_10.5.4.tar" and both failed. Mostly errors related to kernel headers (see one of the error below).

Is there a version that would work better? Or some guide online to help me get started?

Thanks,
Frank

I resolved my issue. The latest drivers / software works after updating the kernel.

Code: Select all

sudo apt-get update # This will update the repositories list
sudo apt-get upgrade # This will update all the necessary packages on your system
sudo apt-get dist-upgrade # This will add/remove any needed packages
reboot # may be needed
sudo apt-get install linux-headers-$(uname -r) # This should work now
