RE: Intel HTPCs/NUCs & Kodi-native 3D MVC Playback - udobroemme - 2021-09-26
No problem, thank you for the explanation. I thought my observations might be helpful and I'm not expecting any additional efforts for my non supported setup.

Can you please check on the scenario where kodi 18.9 with 3d, when you play, can you please click "o" on the keyboard during play and see what is the first line on the top? Does it use hw or sw rendering? And with what engine (during play it is listed in video settings)?
The reason i ask is because in 18.9 code all of the rendering engines were in a single class and in 19 they are split. I only modified the dxva rendering engine...
RE: Intel HTPCs/NUCs & Kodi-native 3D MVC Playback - udobroemme - 2021-09-27
Now I understand what you meant. I never touched the rendering method setting before. It always stayed at "auto". Now I made some tests with both of your versions.
Kodi 18.9: "msdk mvc (SW)". It works with all rendering methods (DXVA, Pixel Shaders, Software) and gives a stereoscopic image.
Kodi 19.1, hw mvc decoder support level=19: "msdk mvc (SW)". DXVA gives a black screen, Pixel Shaders and SW rendering methods give a monoscopic image.
Kodi 19.1, hw mvc decoder support level=20: "ff-h264-d3d11va (HW)". All render methods show a monoscopic image. Imho this is correct because no hardware decoding is supported on my machine.

If that is what i think it is, both the issues we encounter ed are the same. What happens is that the current code (v19) is optimised and so much faster than before. Because of that eye one will render much faster out of sync and the other might never have a chance to be rendered... If that is true, the fix i am working on will solve that. No ETA yet for a fix.
RE: Intel HTPCs/NUCs & Kodi-native 3D MVC Playback - udobroemme - 2021-10-01
That's great news, thank you very much for the update and of course for all your efforts.
There's absolutely no reason to rush. Leia still works with all my favorite addons.

It looks like the fault is in kodi modification s to v19 rather then the MVC decoding patch. When turning on the full screen 3d in kodi v19 without a movie running the setting menus dont have visual depth on my affected system as on my laptop where it works... Can you please compare this behaviour on your system between v18.9 to v19.1? If it checks out, it will point the issue to the same direction.
Update: on kodi v19 where you see black output, please try to click during 3d movie play on "\" key to switch to window mode, and let me know if the window content is rendered correctly in 3d
RE: Intel HTPCs/NUCs & Kodi-native 3D MVC Playback - udobroemme - 2021-10-06
It seems that you're on the right track. When I switch to a window with "\", I get a 3D rendered video. The scaling of one eye view is off like you can see in my screenshot. But apart from that the behavior is exactly like you described.
Btw.: I temporarily also have a Nuc7i3BNH with Intel HD630 graphics for testing available. It behaves exactly the same as my AMD system, even the scaling issue is the same. So I'm quite sure we don't have vendor specific or HW vs. SW encoding issues here.

Hi I've found a Dell with an i5 4590 CPU but only displayport. Can anyone confirm if this will playback framepacked 3d if I get a displayport 1.1 to HDMI 1.4 adapter?

The Displayport on a Dell Optiplex 7970, with an I3-3800 I believe it is, outputs full MVC MKV 3D through a DP-HDMI cable using Kodi 18.1 MVC fork.

Thank you so much! Does it matter which dp version I use?

I'm not sure which version it is, just that it works. I believe from researching it before I bought the Optiplex for this specific purpose that any DP would work. At least any as old as would come with a 3rd gen Intel CPU.
RE: Intel HTPCs/NUCs & Kodi-native 3D MVC Playback - udobroemme - 2021-10-07
From what I can tell it depends much more on the Windows and the graphics driver version than anything else to be successful with getting framepacked 3D output. With every major release later than 1803 I had issues. Sometimes it didn't work at all or there were issues with switching to 3D output or switching back to other frame rates after stopping the movie.
I was successful when I used Win 1803 and the latest Kodi Leia 18.9 mvc build and set the rendering to "Software" in the Kodi player settings. It worked either with HDMI (Intel Nuc7, MFX hw decoding, Intel IGP driver 30.0.100.9864) or DP (AMD Ryzen 2400G, MFX sw decoding, AMD 19.7.2 display driver) outputs.

I think the only thing that matters is that you use a passive DP to HDMI converter/cable (Active ones cannot do 3D).
RE: Intel HTPCs/NUCs & Kodi-native 3D MVC Playback - Statikk - 2021-10-09
Does anyone have a link to the last 18.9 build? I looked around and found a link to 18.7 and the 19 test build but didn't see one for 18.9.
