3D Frame Packed (MVC) output with CoreELEC?

Thanks @rho-bot Very kind of you.

Thanks @Portisch. Great job as always. However it fails stress tests on high bitrate BD3D’s i.e Eternals 2021,Black panther etc when chapter skipping.

@ragico is right , your 9.2.8 has perfect performance including “play main movie”-This I think is key to the last hurdle as it ultimate stress test. Do you have a high rate BD3D’S you can test?
Thank you once again.

This new version is little bit better than the last one was regarding selection of preferred view mode.
The last version was better in the OSD. Kodi HUD during playback was 3D, now it is off, the right eye is a purple hue mess.
When playing 3D full MVC the right eye has a purple HALO on both version.
ISO freezing is not happening for me because my network has enough bandwidth. In normal 2D playback mode a film starts buffering when the bandwidth is low, either from USB pen-drive or from the ethernet side. In 3D MVC playback the player is not buffering to continue when data is available but the decode freezing instantly in buffer run empty case.

I have no idea what you talk about. You need to show and describe “your issue” in more detail.

My description is correct. I will make some pictures later to show what I’m talking about.

Hi all,

I also tested the latest version (updated from latest nightly) on my LG E6 and an Ugoos AM6B+.

It handled everything MVC without issues as far as I can see.

Two things I noticed: HSBS and HTAB (so not MVC) still work fine and still break the interface when returning to non-3D Mode in Kodi. I think, this is known and is also the case in the normal CE21 nightly. Secondly, FSBS (tested with the Kodi mkv FSBS samples from the Kodi Samples page) does not work anymore at all. It worked in the CE21 nightly and my assumption is, that it’s because of the resolution being fixed to 1080p in the mvc dev-build? Since FSBS wants to output 3840 x 1080 and I can’t change this setting in Kodi (maybe on purpose), it doesn’t work, flickers a lot and requires a reboot. Same if I try to change the resolution in Kodi beforehand. As I said, maybe this is on purpose for this testing build and can therefore be ignored, just wanted to mention it in case it was not on purpose :-).

@TK and Portisch: Marvellous Job! You gave us people holding onto our old 3D-gear something we are very much looking forward to!

Play ISO by select the menu should now work again.

EDIT: now it looks like play ISO main title is broken…

I do not see any FSBS, only HSBS on Kodi sample page.

It’s hidden under the Avatar Trailers on the Samples Page, which has a lot of differents choices listed:

e.g. 8th and 9th link from the top.

Yes, only mkv play properly. No way to play Iso (black screen with audio or 2D) depends on the settings.

Checked this version CoreELEC-Amlogic-ng.arm-21.1-Omega_devel_20240617122644
The video is 100% the same as the Dune real vision result.
Congratulations, 3d-FP is rendered and works well.
But there are the following problems.

  1. Ceam outputs 3d-FP video even on TVs that don’t have 3d support :). I.e. ignores data from EDID.
  2. ISO with MVC is played with lags, periodic delays, 1 frame is output twice or three times, but the same video in MKV does not have them and plays without problems.

Latest version preferred mode automaticly selecting not the right mode. The version before was correct in this matter.
If not selecting mode over/under, the KODI OSD looks like this.
Left eye


Right eye

3D full MVC will not decode correctly.

Right eye

When selecting over/under the OSD will be correct, but not the movie itself.

Right eye

The purple HALO on the right eye is clear.

Thank You,

I even have no idea how to reproduce. What is left or right eye and how to show?

Just as a reminder: all requests about 3d are lowest priority as the format is dead, at least since 2021 when Nvidia removed support.

Appreciate all the work You have done. I have no knowledge about the technologie so I’m not the right person to tell You how to work this out.
Luckily the previous version detected the format well. So go back to that version in detection in case of displaying KODI HUD.
I think left eye is the original picture and the right one is calculated from the stored MVC differences data. As far as I observed the picture is decoded well in ALL the ISO or MKV MVC ISO files I have. So no HALO or such artefacts to be seen!
I’ve seen the pictured problem on the so called 3D-full-MVC files whatever that means.
About the buffering.
Kodi handles buffering quite OK when playing from network or USB source. That is not the case when playing 3D MVC. If there is no data to decode, e.g. the buffer runs dry, the player freezes. That would be nice to master out too.
No hurry, You achieved great success.

Only “issues” by show how it should be, how it is with CE and what to do to reproduce will be accepted in future.

ISO start from menu or play title does now work

Are these Avatar SBS samples MVC?
Kodi detect only H264.

@Portisch
Are you a magician?
Everything works properly now including “Play main movie” both for mkv and iso.
In the ancient latin language people who accomplished something exceptional were graded with “10 cum lauda”
This goes today to you and to CE Team.
This build could be the final build for 3D or you are still researching?
Thank you very much.

Where are these avatar samples?

@Portisch thanks, But still getting crashes on high rate BD3D’S i.e Black panther. And 2in1 BD3D’S is not 3D auto detected i.e Resident Evil. paste.coreelec.org/TakesWaving
Paste.coreelec.org/IdealDistract.
These had no issues on your CoreELEC-Amlogic-ng.arm-9.2-devel-1717679789-9.2.8
Even this ‘Avatar 2 The Way of Water (2022) Trailer A 3D Full SBS Flat 1080p DTS-HD MA’- @Xenothar is this file you had issue? It played fine on 9.2.8

@Portisch Is wonderful what you have achieved in so little time so really thank you, i just feel you are so close to perfection.
