Re: Dolby Vision now possible through MP4 Mux.
So just had a quick try with Plex beta.
Plex will pass TrueHD/Atmos from m2ts and HDR10 MKV but I can not for the life of me get it to trigger Dolby Vision on Ugoos 0.4.0. Added to this a Dolby Vision mkv will only play in HDR10 and stereo... My Plex is set to March frame rate, maybe that is the problem?
I have TV led processing enabled with my LGC9, I wonder if people that are triggering Dolby Vision have LLDV enabled?
Just for clarification the MKV files I tried work fine with patched Fandangos Kodi on the same device.

I was not using the PLEX beta. will try that. With the stable version, the only way I can trigger DV with mkv file is by selecting lossy audio before playback

Exactly the same here with a Panasonic GZ2000 oledDaMacFunkin wrote: ↑Wed Mar 24, 2021 7:17 amSo just had a quick try with Plex beta.

Tried also enable/disable frame rate match, resolution match etc.
Tried Plex from playstore and latest beta/official builds.
No way to get DV with Hd audio passthrough
It works in Kodi Dv edition.

Re: Dolby Vision now possible through MP4 Mux.
yep, with PLEX beta, now TrueHD atmos bitstream works with HDR10 files.
but
everything else doesn't...
AC3 / EAC3 5.1 = lpcm 2.0 (HDR10 & DV)
DTS/ DTS-HD = lpcm 5.1 (HDR10 & DV)
At least now we know that plex on this device CAN bitstream TrueHD. Now I'm sure ugoos can fix everything.

Re: Dolby Vision now possible through MP4 Mux.
Got mine today. Seeing similar issues, and more. Audio pass through usually doesn’t work. It was working for me briefly, possibly while I had refresh rate matching off in Plex. Now that I’ve turned on refresh rate matching and resolution matching, no bit streaming to be found. Often getting stereo PCM, and sometimes multi channel PCM.
Before turning on refresh rate matching in Plex, was getting tons of jittering and audio sync issues in 1080p SDR 24p MKVs. Turning on refresh rate matching fixes that.
Also seeing some serious stability issues in basic use.
Exiting a movie in Plex usually leaves the HDMI in a broken state, where there is a black screen, but sound works. Repeatedly hitting the power button fixes it, usually.
Resolution switching and color mode switching are not reliable. Sometimes I don’t get into DV mode, sometimes I do. Sometimes DV mode or 1080p mode or HDR mode “sticks” after a movie.
Playing DV movies is not starting reliably. Sometimes it’s starting in SDR. Restarting fixes it.
This is all on 0.4 firmware, Ugoos AM6 plus, and beta Plex. Connected directly to an LG CX, with ARC to a Denon AVR.
I think this box has potential, but there is work to do on stability and audio pass through.

Re: Dolby Vision now possible through MP4 Mux.
Thanks. Yes this makes sense and I read somewhere that Panasonic actually advertise Dolby Vision and HDR10+ Capabilities through a single custom EDID field which in the past has caused problems for other sources. I guess either Panasonic can fix their side but I don’t like the chances of this. Or Ugoos can fix to interpret Panasonic’s EDID. I don’t like the chances of this either since there’s so many other problems with DV playback that need to be fixedDaMacFunkin wrote: ↑Wed Mar 24, 2021 7:17 amSo just had a quick try with Plex beta.

A fellow Panasonic owner! Do you also only get LLDV option in DV display settings on the Ugoos?ragico wrote: ↑Wed Mar 24, 2021 11:13 amExactly the same here with a Panasonic GZ2000 oledDaMacFunkin wrote: ↑Wed Mar 24, 2021 7:17 amSo just had a quick try with Plex beta.

Re: Dolby Vision now possible through MP4 Mux.
Hi, like I said I had a similar problem with LG and newer Realtek chipsets, LG released firmware updates for it themselves, you may need Ugoos to elevate it to Amlogic to elevate it to Panasonic.bedders wrote: ↑Thu Mar 25, 2021 2:52 amThanks.

Re: Dolby Vision now possible through MP4 Mux.
With the vimu media player every dolby vision movie works with frame rate switch and ac3 and dts passthrough without stability issues only truehd and dtshd and dtsx doesn't (stutter) . With passthrough off every movie plays perfectly. I really hope the kodi modder can stabilise that kodi mod. You can run the vimu player out of kodi if you want to, if you use the app xbmc wrapper.
Edit: Another strange thing is that I also have problems with the official kodi 19 version installed from the playstore with the ugoos am6 plus and newest beta firmware. Sometimes I have to start a hdr10 mkv file 3 or 4 times before it starts.
I don't have any issues if I use another player like vlc etc.

Re: Dolby Vision now possible through MP4 Mux.
"A fellow Panasonic owner! Do you also only get LLDV option in DV display settings on the Ugoos?"
Dolby Vision settings:
Dolby Vision enable low latency (YUV)
Dolby Vision disable
The Panasonic GZ series (2019) do not support Tv led as far as I know.
This feature has been introduced in 2020 HZ series.
By the way, I am waiting for an Oled LG CX in nest days and will report accordingly-
Re: Dolby Vision now possible through MP4 Mux.
But I'm not sure that, coz troubles in amlogic SDK.RESET_9999 wrote: ↑Wed Mar 24, 2021 10:32 pmAt least now we know that plex on this device CAN bitstream TrueHD. Now I'm sure ugoos can fix everything.
Also I'am look fast at Exoplayer 2.13 sources code and not found using process DV-EL metadata in mkv-rips (profile 7)

Re: Dolby Vision now possible through MP4 Mux.
Ugoos owners, what method are you using to install the 0.4 firmware?
I'm following the OTA FIRMWARE GUIDE from this page (going to about menu and finding AM6_ota_0.4.0.zip) -- https://ugoos.com/firmware-upgrade-guid ... ic-devices
After reboot it's bringing me to recovery where it's failing the secure check. I've already re-downloaded and tried again.
Edit: Oof, I can't even get ethernet to work what the hell? My experience with this thing isn't off to a great start.

Re: Dolby Vision now possible through MP4 Mux.
Just got my AM6 Plus yesterday. Since then I've been trying my *ss off to install any OTA from USB stick. No dice. Everytime I got "bad file descriptor" error.
I wanted to try this dualboot thing so today I installed the CoreElec dualboot beta 0.4.0 from the Ugoos site (this is NOT an OTA file) by hooking up my Ugoos to the pc and running the USB burning tool that comes with the package. This went smoothly, no problems.
Same here. What you want to do is enable WiFi and the you can connect through ethernet. After that, WiFi can be disabled again.
Re: Dolby Vision now possible through MP4 Mux.
Thanks for the tips, but still can't connect to ethernet. I've tried three different cables that were all working with the devices they were already connected to including my LG TV, OPPO, and Shield. Already close to packing this thing up and returning it to Walmart.ArArdin wrote: ↑Thu Mar 25, 2021 8:08 pmJust got my AM6 Plus yesterday.

Re: Dolby Vision now possible through MP4 Mux.
JFC rebooting several times did nothing, but of course physically unplugging the power and plugging it back in made the ethernet work. This device is going to be a rollercoast ride isn't it? 
EDIT: LMAO that also fixed my issue with the OTA firmware not working. I ran it again with no changes and it just worked. I'm now on 0.4.0
