Black screen on all headsets #9

Closed RAGEdemon closed 2 years ago

RAGEdemon commented 2 years ago

Thank you for this.

Issue: Native Vulkan OpenXR (SteamVR/Oculus) as well as WMR via OpenXR-Vk-D3D12 give black screen.

More details: WMR HP Reverb G2 + OpenXR-Vk-D3D12 gave black screen. I opened issue with the developer of OpenXR-Vk-D3D12. He tested it with a Quest 2 and a native SteamVR head set, both of which support native OpenXR Vulkan. He too got black screen.

His conclusion was that the issue seems to be with VRScreenCap?

OpenXR-Vk-D3D12 Issue Thread here

Full reply from developer:

_Hello,

I have downloaded v0.1.0 of this application from here: https://github.com/artumino/VRScreenCap/releases/tag/0.1.0

I have tested it with:

Oculus Quest 2
SteamVR OpenXR runtime

Both of these OpenXR runtimes natively support Vulkan (ie: can be trusted). I get black screen for both.

As far as I can tell, the issue is not with OpenXR-Vk-D3D12, since the app is giving me a black screen with 2 fully qualified OpenXR runtimes.

Please contact the developer of that application._

Hi, right now if no geo-11 game is running when VRScreenCap is launched nothing will be shown on the screen. Have you tried closing VRScreenCap, launching the game, and then relaunching VRScreenCap?

There should be an output.log file near the executable with some information on what's happening.

output.log

Please find attached. Game is running and works fine with katanga.

Clarification: Game shows SBS image on monitor with VRScreenCap app. Presumably this is how it is meant to show. When running with Katanga, it shows TAB image on monitor.

Update: It works!

I clean installed the game, the fix, geo-11; then made manual changes to the .ini files to the point where a TaB image shows in screen as when Katanga works.

Issue is with the shortcut created by geo-11 mod manager application - it launched game in SBS mode, even though d3dxdm.ini says Katanga_VR.

Manually launching game and manually launching VRScreenCap app 'fixes' the issue.

Only problem now is that the screen is very washed out - blacks are very light gray. Maybe some error in the DX12 to VK conversion?

If I exit VRScreenCap and open Katanga instead, colours are perfect...

It's probably a difference in colorspace that I'm not accounting for, can you attach the log of a working instance again? Also what game is it?

RAGEdemon commented 2 years ago

output.log

Game = Visage.

Thank you for your work.

artumino commented 2 years ago

I can confirm I was doing the color space calculations wrong, should be fixed in the next release

artumino commented 2 years ago

Just published version 0.2.0, it should fix the issue

RAGEdemon commented 2 years ago

Thank you - one of our cummunity members reports it as working... and wishes for a way to centre the screen... but that is another issue completely.

We're greatly looking forward to seeing more development of this app if you have the time - thank you :)

Thanks for the report! In theory, the recentering logic should be handled by the OpenXR runtime, although I've noticed that in SteamVR the "Recenter Seated Position" has been moved to a menu only accessible from the desktop. I'll surely consider adding an in-app recentering mechanism.
