Arch Linux User Repository

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.

That was quick! Thank you! I just built it with 5.6.10 without issues. After a brief look at Resolve and Nuke with Decklink Studio 4K it seems to be working as expected.

Version 11.5.1 has just been released unfortunately it does not build with kernels 5.6.0+ so I patched the driver to make it compatible.

However I'm not familiar with kernel module development so consider support for newer kernel experimental. Changes are minimal so hopefully I did not introduce any bug.

Yes, you can clone the git repository (https://aur.archlinux.org/decklink.git), go to the commit corresponding to the version you want and build the package with makepkg -i.

Is there a way to build the previous version? Sorry still new to building files I'm also running manjaro.

No update yet and support could not give me estimate release date last time I asked. You can ask them directly, maybe it will make the issue more visible.

@goldensuneur

I'm guessing still no luck with the BM update yet?

Here's my failed install log for dkms for kernel 5.6.8

Yes, and it won't work until Blackmagic releases an update. I'll open another support ticket asking if they know when the next version will be released.

DKMS modules do not build on 5.6.5 either.

DKMS modules do not build with linux 5.6+, stay on lts for now. Blackmagic support is aware of the issue we have to wait until they release an update.

@goldensuneur Weird. It wasn't showing up until I reinstalled, rebooted, and reinstalled again.

I always get stuck with weird issues like that.

But I am still having issues with audio on this new driver, but I'm guessing that it's a Blackmagic issue with their driver, since it's also happening on my Windows install.
