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.

Waking from suspend results in threads for "DesktopVideoUpdater" and two threads for "DesktopVideoHelper" consuming an entire 100% of a CPU each, for a total of 400% of a CPU being consumed. This performance bug has been reported to https://forum.blackmagicdesign.com/viewtopic.php?f=18&t=109244 DesktopVideoUpdater and DesktopVideoHelper and comments say it happens on Manjaro, Debian, Mint, and Arch.

I am also noting that video capture in OBS doesn't work on the realtime kernel (linux-rt)...simply produces a black image in OBS and freezes OBS.

thanks for the info, will try that as soon as I figure out how :)

MAJOR EDIT: Was able to fix by switching to a different obs package. I ended up switching to obs-studio-browser. It doesn't seem to have anything missing from the original package, but it is updated to 26.1.1

Wrote this a couple posts back before it got buried.

You need to update OBS to 26.1.1 by adapting the PKGBUILD.

For some reason the Arch repo version is still stuck at 26.1.0 containing a bug for Intensity cards (I had the all green thing as well).

@daren can you share all of your obs settings for the blackmagic because I get the same issue after updating to 12.0

YUV doesn't show anything but green

Yes, no issues using my Blackmagic Intensity Pro with OBS 26.1.1 feeding a 720p60 HDMI input.

@daren So you don't get the half purple half black screen?

disc-kuraudo commented on 2021-01-23 09:22 (UTC)

It works for me post 12.0 update on latest 5.10.9 kernel. Use other cables and other input sources as well, clean HDMI slot(s) maybe. Just to rule these things out.

@goldensuneur

Well The box was open and the seal in the static bag was broken so I am trying a replacement first because I only get those half purple half black input if the resolution is manually matched to the ps5

If issue persists I will leave a thread on their forum, thanks!
