I have not tried 3D subs really (but I do know, that they are only for one eye for me as well, as they look fine without glasses and horrible with glasses :-)). But I think, that Kodi cannot properly deal with the subs embedded in the mkv? If I remember correctly, you need to extract the subs (or download them) and place them next to the MKV for Kodi to handle them directly in 3D. You can then set the depth.
Again, I haven’t tried it myself, but I vaguely remember that. May be worth testing by you?
I guess technically, Kodi could handle 3D subs from within the MKV, but I guess it is not or was never fully implemented?
It’s not just the 3d subtitles that are wrong, but all types of subtitles and the gui. It is only displayed on the left eye. The subtitle is also displayed like that when embedded and unpacked. Only MVC 3D (iso, mk3d) presents the problem, other 3D (sbs, tab) displays fine, both eyes are displayed (sub, GUI).
I updated to the latest 21.1.1 and 3d playback isn’t stable on my Ugoos AM6B+, mvc keeps crashing and rebooting the unit.
On a whim I installed a old Nightly from 20240817 and playback is stable again.
Then I updated to cpm’s T8 and after trying many different types of 3D, and SDR and HDR it seems like it might have everything in place again. I don’t understand why that seems necessary, and am reluctant to reboot the unit.
I just happend to find the “movie” you were asking about some months ago? I stumbled over it and remember somebody asking here. If I remember correctly, you were asking about the clip from the Kodi 3D Samples with the guy on the bike fleeing from some gunship?
It’s not really a movie, it is a short called “Ruin” by Wes Ball (Ruin (2011)). It happens to be on the BD of The Maze Runner (first one) as separate 2D and 3D Version and is 8:11 min (3D) long.
It seems that the 3D mode does not function properly without hardware acceleration, and the 3D > 2D mode is completely non-functional. However, with active AML (hardware) acceleration, it works as expected.
To reproduce: switch off hardware acceleration, start 3D movie, select without 3D (2D Mode).
to my understanding that is expected behaviour as 3D support for this platform relies on AMLogic.
There’s also a mention somewhere that due to using acceleration some titles might have issues (performance or smth else) due AMLogic bug.
so now i’ve got the Dune Homatics R 4K Plus and manage to successfully boot it with CoreElec from an USB stick.
I’ve installed CoreElec on the USB-stick exactly as recommended in the Install-Guide of the CoreElec homepage.
TV box boots up fine, Kodi shows up as expected.
But when i start a 3D Movie (regardless if it is from an ISO or a backup directory created by MakeMKV) it plays OK only for a few minutes.
Then playback stops and the Box freezes. Leaving me behind with a totally disturbed image in multiple colours.
Or sometimes the image disappears and leaves a black screen while the movie is still running (you can tell by the scroll bar and the audio).
Also when the movie is still played back it stutters.
And I can’t get rid of the Soap Opera effect although I set output to 24 frames and also input of the TV to Cinema mode.
The issue with stuttering and Soap effect also happen when watching 2D videos in CoreElec.
Also scrolling forth and back might cause CoreElec to freeze.
And finally BluRay menus don’t work although I’ve installed the BD-menu addon from the repository.
Is anyone else experiencing such problems?
The TV box is still on Android 11. Since you can’t revert to Android 11 after updating to 12 i haven’t tried to update it because i don’t want to mess with the warranty.
Any help is very much appreciated
PS:
when I boot the TV box with the Homatics’ original system (and not CoreElec) everything plays fine and disk menus also work fine
Only (and huge) drawback here: no 3D
Hi, the Dune Homatics R 4K Plus cannot play 3D Frame Packed (MVC) only this:
3D video: Side-by-Side, Top-and-Bottom
I don’t know if that is the reason.
By the way, a question for all of you who have any media player of this type or similar but plays 3D MVC. Have you tried this? It’s in the MakeMKV forum:
I assume what you’re attempting to do is rip a 3D Blu-ray to something like a HDD or SSD, plug that in via USB, and play back the frame-packed 3D Blu-ray on your standalone player on your 3DTV. This is easy as hell, but PICKY as hell. SO easy in fact that I couldn’t believe it was something so simple, but I’ve tested this now with several discs, and it has worked every time.
Rip just the movie file with MakeMKV, and make sure you check the MVC video stream. All of that we knew…
Open the resulting MKV file with tsmuxer and export to m2ts. Now - HERE’S the VITAL step that makes the file work…when you load up the MKV file into tsmuxer, the MVC video is in Position 1 by default. You MUST highlight the MVC video and move it down to Position 2. THAT’S IT. That’s the whole damned problem. I don’t know why this is a thing, but it is. Once you get your m2ts file, just throw it on your USB drive, and your player will play it back just like a 3D Blu-ray disc, auto-detecting the 3D signal and all. Hope this helps!
hi @Ferdinand
i suppose you’re comment is directed towards me.
Yes, the Dune can’t play framepacked 3D by its default system. At least afaik.
But it can play them via CoreElec.
It does recognize my framepacked 1:1 copies generated by MakeMKV and plays them.
It also recognizes and plays framepacked 3D-MKV-files.
But only with the problems that i listed.
Can anyone that has the Ugoos AM6B+ and a Zidoo box comment on the differences in the 3D? Do they both perform equally or does the Zidoo do a better job and how? A friend is selling his but will give it to me for free if I want it. I just have to pay shipping. If it is not much difference, I rather him sell it. I do not want another device if I do not need it.
Zidoo is a little better, but having AM6B+ as a single do-it-all local media box has its plus points. The main issue w/AM6B+ is AmLogic’s MVC decoder bug which plagues a handful of 3D titles w/macroblocking artifacts. But, it’s fewer than 8 if I’m recalling… the original version of ‘Avatar’ 3D (not the recent release), ‘Gravity’, think ’ A Christmas Carol’, and a couple of others.
As far as I know, this is not like “the whole movie is bad in 3D”, but like once for a second per movie, but consistently happening at that second.
My question for AM6b+ users would be: Do 3D-MVC movies run without issues for the full length on your units? The last time I tested (some time ago, documented earlier in this thread with an LG E6) my AM6b+ crashed every between 5-30 mins back to home screen. I have never made it through a whole movie and gave up after some attempts.
Not recalling how severe the macroblocking issue was–my primary 3D player is a Dune HD Real Vision 4K Plus (snappier than Zidoo, and a better UI if you use Android/Google TV option). Same excellent 3D quality.
With AM6B+, my MVC movies run/play through the entire length. But, I almost exclusively have MKV’s, not ISO’s. Latter takes more overhead/power to play.
Better as in no macroblocking, and I find Dune/Zidoo’s 3D rendering (via Realtek’s MVC decoder) more pleasing overall… less rough (hard to explain, but a smoother looking picture), and slightly better 3D effects (depth, separation, pop-out). And handles 3D ISO’s as well as MVC MKV’s.
What TV do you use, Can you take short clip to show diffs of depths & smoothness, of course when you have the time, thanks. I returned my dune because i thought there wasn’t much difference on my lg c6.
