Atmos should just work if you have passthrough enabled in system/audio settings. Make sure TrueHD passthrough enabled and that kodi is playing a TrueHD audio track.
Thank you.
Are you referring to the "system/audio settings" in Kodi? I have the channels set to 7.1 and the HD Audio option was on but I don't recall it mentioning TrueHD specifically.
I tried this today with the LibreELEC-RPi4.aarch64-13.0-devel-20260831213406-7e8026e.img on a Pi4.
Amazing!!! I have a 20 foot HDMI cable plugged into my Denon AVR and the 3D is even detected on my projector as expected with my MVC files! Love it!
I have a couple questions:
I use the PM4K add on since all my media is served from my Plex server. Since my profile is used on all my TV's I prefer that because it keeps all my media in sync with where I left off etc. It plays fine but if I don't set the 3D setting to "Preferred" on playback it gives you that intermediate screen asking how you want to play it back. If I leave it at that setting the popup screen is not visible unless I "escape" out of whatever is covering it. I think the cause is related to this Kodi build becasue I run PM4K on all my 3D linux players (Vero and RPi) and this is the only one it does that on. If I change that to preferred it doesn't ask that question and it moves on happily to play my media. Is this something that the PM4K would have to address or am I barking up the wrong tree?
I tried playing a movie with TrueHD 7.1. It plays it fine, but my AVR only shows "multi input" not Atmos like it normally does. I have my Kodi settings to 7.1 audio but can't find any other settings specifically related to Atmos. Is there anything else I need to tweak for this to work?
Off to more playing! Thanks for the awesome resurrection of this software!
Sorry to resurrect an old thread but I'm really wanting to get mvc working on my pi4. I've tried the 9.2.8 version suggested but when booting the pi says the board requires newer software. Is there any way to get mvc on a pi4? Thanks
That on a Pi3B+ and it seems to work fine. It’s not my primary 3-D player anymore, but that might help you.
noggin the RPi4 SoC is basically an RPi3B+ with faster clock speed and an extra IP block for 4K HEVC, so 3D works on RPi4 under the older LE9.2 codebase as nothing really changed, but support needs to be reworked for the newer GBM/V4L2 pipeline.
Sorry to resurrect this old thread, but.....are you saying that if I download this:
https://releases.libreelec.tv/LibreELEC-RPi4.arm-9.2.8.img.gz
And load it on a Pi4 it will play 3D-MVC? I realize it would be an older build, but I ONLY use this for playing 3D.
I just downloaded the RPi3 version to put in a temp 3D player when I saw that comment.
Still would have been nice to be able to play my 3D Videos on the pi4.
Agreed. Right now I use a Vero-4K+ for my main TV to play both 4K and 3D-MVC. It would be nice to be able to use a Pi4....since I have several of them....to connect to my other TV's.
For commercial streaming services I still rely on my Roku, Shield and other streaming devices because of all the encryption limitations.
It's up to the Raspberry devs to update/implement 3D stuff
Do you mean some underlying stuff is up to the Raspberry Pi folks?
I ask because if it were simply up to them why would anyone need LibreElec? Throw Kodi on a PiOS install and 3D away!!
9.2.8 has some improvements, but nothing related to 3D-MVC
I assume I should still use that as it's the latest though, correct?
LE 9.2.6 remains the best option for 3D support.
So looking at the current downloads there is a 9.2.6, but there is also a 9.2.8.
Raspberry Pi 3 / 3+ – LibreELEC
Should I assume that 9.2.8 simply came out after this comment was posted and now that version is the "best" version for 3D-MVC?
PS: what is the "Widevine fix"?
I’m in the same situation. I run a 3B for no reason other than 3D-MVC. I did buy a Vero4K+ But I still have three 3-D TVs. I’m not buying three of them.
The ideal solution would be for someone to convince Nvidia to create 3D-MVC drivers for the shield…….;)
Nope.
Simply no... SBS 3D videos play normally on any software player I've tried, they simply consist of two both frames side-by-side ... any mplayer/VLC/SMplayer plays them fine - apparently with no "driver" the projector does the decoding/alternating of the frames.
None of those players bother to have 3D menus or 3D subtitle support. - which is still working for nice video playback.
Here we have a perfectly fine SBS menu, subtitles in 3D , but instead of displaying both frames inside the picture, like those players do .. it seems we somehow crop the output to one single frame.
You would think this is true, but I have had TAB files and to a lesser extent SBS files that will play, but not properly on any of the three 3DTV's I own including one projector even though I could play the file on my PC and they appear to be "normal". Could be anectodal, but I don't know if your statement is 100% correct.
Regardless, SBS/TAB is only half resolution. I'm not goign to get into all the reasons for that, but the info is out there if you want it and didn't know this already.
MVC is the only way to consume this media in 3D without losing any quality. The half-res stuff may be "good enough" for many use cases or preferences, but it's not the real deal.
ISO support is FAR less critical to me as I rip all my media for playing in Plex primarily. I only use Kodi-based players for 3D-MVC. The Vero4K+ is the only open-source player that will play virtually any format up to the last couple years. I don't think it handles DolbyVision, but Atmos, 4K, 3D-MVC etc.....no problem. If you use any streaming services like NetFlix, Prime etc it doesn't handle those without hacking so it won't replace my Roku or Shields fully at this point. Being able to run this on a Pi4 would be a step forward since it can handle HD audio, 4K etc.
Display MoreI am just joining this thread of endless wait.
What a IRONY !
1: I "upgraded" from a PC to Rpi3 to make it more "smooth and modern"
2: then discovered that 6ch audio over HDMI was not supereasy, so I got TOSLINK board
3.. then I discovered that Rpi3b would not handle h265, so I "upgraded" to Rpi4 ..
4...now it can't play 3D...
5... I will most likely have to go back to a PC and Kodi on Ubuntu to get things working.. (revert to state "0")
3D-MVC is the ONLY thing I use any Kodi-based players for.
For anything else I use a brand-named device like a Shield, Roku etc. No fiddling and they just work.....plus you can get the commercial services on it, unlike Kodi......mostly.
Bizarre this regression, i have been using PI with kodi and 3D files since a very very long time
I don't think it's a regression. 3D has never worked on the Pi4 builds.....yet. It does still work on the Pi3 though. You just can't get 4K, HD audio etc that the the Pi4 is capable of.
I too, am waiting anxiously for this feature for the Pi4 builds!
Both those links in your post work fine for me
Yes, I don't understand what happened. I could download any other versions fine in FireFox. I was able to download even that 9.2.5 release on my phone to iCloud without issue. I couldn't do it on my desktop last night.
This morning it works fine though. Sorry for any false alarms. I have no idea what was going on.
I haven't heard anything new about this, but 3D-MVC support was announced when the Pi4 was released:
LibreELEC (Leia) 9.1.001 ALPHA with Raspberry Pi 4B Support – LibreELEC
Since then I have seen threads here and other places where the delay was about the new Linux core, video drivers etc.
Today I see a new comment on an old thread basically saying that it won't happen:
I am NOT complaining about the delay. I appreciate what I get! I would just like to see an "official" answer as to whether this is still on the roadmap for the Pi4.
I know the Pi3 build works fine, but it can't handle 4K and HD audio so LE for the Pi4 is the closest thing to a "play everything" player with the possible exception of the Vero-4K+. I bought one of those in the last couple weeks. It's a nice box, but no, it can't play 3D-MVC at this point. There is a buggy, older build of OSMC that theoretically will play 3D-MVC, but it didn't work well for me. It's a work in progress as well.
I'd just like to know if LibreELEC is still the king of the 3D hill!
Thanks!!
The thing is that LE is a free project based on KODI and 3D has become less and less important. So when you are able to develop 3D yourself on LE participate in the project, otherwise you cannot insist to get it. Simple as that
I didn’t insist on anything. When the Pi4 came out they announced that 3D-MVC was going to be supported but they didn’t have a timeline.
You are claiming that it isn’t going to happen. Do you work for LibreELEC? Was some announcement made that the plan has changed to not support 3-D?
I’m not saying they should or shouldn’t. I would like it of course, but I still didn’t insist on anything. I’m asking if there’s been an official statement from them about the subject.
Is the download link working for any one else? It is broken for me.
However, 3D is not in focus anymore that's why developpers do not put effort anymore into this feature
Huh? Are you saying that LE is not going to add 3D-MVC to the Pi4 version? Is there an official announcement about this?
there might be a special build of LibreElec
Long ago the LE team said that 3D-MVC is going to come for the Pi4. They just didn't have a timeline. IIRC it had something to do with the Raspbian kernel being updated to the Linux 5.X line because of the new video drivers or something to that effect, and apparently that hasn't happened yet.
