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.

Ok that's great, indeed it works with the latest version, thanks for the update !

Latest version released today by Blackmagic fixes the build issue.

sleduc commented on 2023-09-25 10:28 (UTC)

Hello,

The package does not build any more with kernel >= 6.5.0 due to some kernel API change : see error in https://pastebin.com/3UmdRxhx

Parameter 'vmas' was removed from functions 'get_user_pages' and 'get_user_pages_remote', since 6.5-rc1: https://lore.kernel.org/lkml/20230626085035.e66992e96b4c6d37dad54bd9@linux-foundation.org/

The following patch seems to be fixing the issue : https://pastebin.com/FZVwR181

@YAOMTC If the user has an alternative kernel installed they would have a different header package. See the dependencies for dkms. It is up to the user to also have the appropriate header package installed for dkms.

YAOMTC commented on 2023-06-28 22:31 (UTC)

Shouldn't linux-headers be a dependency here? Won't work without it.

goldensuneur commented on 2023-01-06 22:36 (UTC)

If not already done you should consider sending the segfault trace to Blackmagic support. This is not the kind of fix I can do without working hardware on hand. Especially if the problem is within the binary blob they provide.

I'm running on an Intel CPU, and I needed to set the kernel parameter ibt=off to fix the segfault reinis mentioned. Seems similar to https://github.com/NVIDIA/open-gpu-kernel-modules/issues/256

reinis commented on 2022-11-02 14:18 (UTC)

Segfaults on runtime with 6.0.6-arch1-1

Hi, I see no such devices after installing the package on 5.19.4-arch1-1. I'm using a thunderbolt sonnet device, maybe it could be its driver?

goldensuneur commented on 2022-06-06 13:05 (UTC)

Thanks for the fix, I updated the package with a patch inspired from yours to make sure it's compatible with previous kernels.
