[Win][v19+] Intel HTPCs/NUCs & Kodi-native 3D MVC Playback
#1
This is a continuation of the work done by others in Win - Intel HTPCs/NUCs & Kodi-native 3D MVC Playback which is dedicated to release prior to v19. This thread deals with Kodi v19 and beyond.

The intention of this fork is to add full frame 3D stereoscopic video playback capabilities to Kodi using a patched version of ffmpeg (video decoding), IntelMFX (HW based video decoding) & DirectX11 (HW accelerated rendering). 
Upstream Kodi 3D playback is limited to Side-by-Side and Top-Bottom - both half resolution quality and this fork completes it by adding support for full-frame 3D. Due to 3rd party libraries usage (MFX) and patched ffmpeg integration, this fork will not be able to be merged to the upstream Kodi code. 


TODO - add additional info on the fork here

How to determine if your setup will be able to playback 3D stereoscopic using this fork:

This fork should work fine on most of Intel's 3rd to 5th gen PCs. Specific HW can be searched on the link noted above to see if it has been reported as working in the past. I use a Gen10 and Gen4 laptops with this fork and both show full 3D correctly. The test guideline is as follows (in that specific order): 
  1. You have a 3D capable LCD or projector - aka display device
  2. In Windows "Display settings" dialog, you can see a "3D display mode" checkbox or a binary state slider and clicking it cause your display device to enter/exit to 3D mode
    1. In case you have 3D capable display and dont see this checkbox, you might need to either replace the HDMI cable to a better one, update the display card drivers, or make sure you are in single display view (and not extended or duplicated) 
  3. Install this Kodi fork, download one of the 3D MKV example from Samples (wiki) and attempt play it in Kodi
    1. In case you see black image on both eyes or 2D image, you might need to lower the value of the MFX HW level under the Kodi player settings
    2. In case you only see black image only on one eye or one eye is skipping check if your GPU has a driver update
  4. If #1, #2, & #3 are passed - this is the fork you've been looking for

  • v19 - build 2 - 30-May-2021
    • Changelog:
      • Add MFX level setting - by default the MFX HW level is set to 20, this might be too high for some PC with older GPUs. If this value is set too high the decoding of the 3D content will fail and you will see the video in mono rather than in 3D stereoscopic. Another symptom is that when click on "o" during the 3D video play you will see that "MSDK MVC (HW)" is not listed as the Video Decoder which is required.

TODO list:
  1. Keep up-to-date with Kodi's upstream releases - ONGOING
  2. Updated libbluray - to latest used by kodi - the required API for reading blurays or ISOs does not exist on the latest libbluray code - DONE
  3. Eye inversion not always working - most likely related to bug #1 - according to the logs Kodi identifies that the eyes should be flipped, attempt to flip them, but for some reason they are rendered out of order
  4. Fix bluray 3D menu view
  5. Half resolution (htab/hsbs) fail play when auto upscale is active

Yeah, top/bottom rendering does the trick at least on my Intel Nuc test system. Many thanks for figuring out the workaround and of course for the new version.

Since newer win 10 versions break 3d in kodi, I presume win 11 does the same too? Anyone tried?

have you tried to watch an entire film?

the reason i ask is i've used powerdvd to play 3D.ISO and discs directly on HTPC before and in my experience only geforce/radeon cards work best when playing full frame 3D.

whenever i've tried to use intel i get dropped frames on powerdvd.

i dunno if it's because it's Intel or just the sucky nature of powerdvd, no clue... just relaying my experience.

I updated my 10th gen laptop today to win11. Worked fine with latest Intel GPU drivers.

Is anyone else missing 25 and 50hz refresh rates with the current build? (Could be my hardware but I cant select 25 or 50 in the resolution whitelist and hence 50hz content has bad movement)
Reply

50/25Hz is working fine here and i can whitelist both modes. Does your display support the PAL refresh rates?

Display definitely supports these refresh rates and it has worked previously. Must be something else in my setup, thanks for confirming it is not the 19.3 build.

Hi
50/25 Hz is working fine for me too.

Installed Windows 10 1903 and this version of Kodi on an Intel NUC NUC5CPYH. I enabled 3D stereoscopic playback in the settings, but every time I begin playing a 3D MVC video, a message pops up saying "3D Stereoscopic Disabled". Any ideas what the problem is?

Hello
There was a user manual for the configuration in the previous tread, page 1, 
but I can't find it anymore.

Thanks for replying! Made the suggested changes and was seeing the same behavior initially (Stereoscopic 3D Disabled). I'm not sure what I changed (might have been reducing the 3D hardware level to 0), but Kodi did start to switch my TV into FP mode (which it wasn't doing previously). But the good news stopped there. It detected the 3D mode as over/under. It's a MakeMKV rip. I'm not sure, but wouldn't it be interlaced? Oddly, the video controls replicated on the top and bottom, but the video itself did not. It remained full screen and 2D. Not sure if I'm explaining that clearly, but imagine the normal 2D video overlaid with duplicated video controls -- one in the middle of screen and the other on the bottom.
