Black Magic version

General

Good morning everyone!!!

I’m using Caspar 2.4.3 on Ubuntu Linux.
I’m thinking about updating my DeckLink Duo 2 driver to version 15, which is available on the Blackmagic website.

Does anyone have experience with or any issues using driver version 15?

Thanks for the help.

Sorry this isn’t really an answer to your question, but I think that 2.4.3 is built using the v11 BMD SDK.

I’m running my machines using Decklink Drivers 12.4.3

I’ve not tried a more recent release.

Also - I’m on Windows.

The early versions of server 2.4 were built on on the earlier versions of the decklink SDK, but the Github CasparCG Server changelog.md file says that version 2.4.2 added a fix to enable drivers 14.3 and later.

My (Windows) experience tells me that 2.4.3 works with both the older and newer decklink SDK’s.

Thank so much!!!

Having just built an Ubuntu 24.04 host, Decklink drivers V15, and CasparCG Server 2.4.3 I’m happy to confirm all worked without issues.

What is your Decklink configuration in your caspar.config?

I have a test bed system using a dual-boot Intel NUC i7 with Windows 11 and Ubuntu 24.04 as the available operating systems. The NUC uses a Thunderbolt 3 connection to a StarTech Thunderbolt to PCIe chassis containing a Decklink Intesity Pro 4k in slot one, and a Decklink Duo in the slot two. The Decklink Duo is configured with two BNC for each logical output (Fill + Key). The channels part of the casparcg.config file is shown below.
