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.

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?

daren commented on 2021-01-23 09:22

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!

Blackmagic just released new drivers however they do not compile on new kernel so I kept the patches I made for older release. As usual, I'm not a kernel dev so my patches may introduce bugs. I encourage you to complain to Blackmagic if you want proper driver for linux 5.10+ (they have been aware of this issue for months and haven't done anything yet) or stick to lts releases.

@lorddickfist I used to get this kind of artifacts when I selected the wrong framerate / resolution.

Getting black screen on auto, and if I set it to 1080p 59.94 I get a purple screen with half black like this: https://imgur.com/aLNWkHS

Mediaexpress same thing DesktopVideoHelper.service starts correctly and recognizes device.

and... it works!

I first tried LTS but it doesn't seem to be compatible with the newer drivers I need for the RTX 3070.

Then finally, back in an updated kernel 5.10.8, I was digging around in the BlackmagicDesktopVideoSetup and found the connector settings, it defaulted to paired connectors. After configuring the connector to single ports for my setup, I can now see the video feed in CapturePreview! yay!

thanks again for your help with getting it working!
