ExoPlayer isn't relevant here, it doesn't do any of the Dolby Vision processing.
That's up to Android MediaCodec and the proprietary pipeline to deal with.

"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-
I don’t believe that’s the case. My understanding is that Panasonic has always had TV led DV support on their OLEDs. What has been a problem is source devices detecting it due to the way the capabilities are presented in EDID. So this would be possible for Ugoos to fix their side. Otherwise we would need something like HDFury Dr HDMI to fix it up. I’ve asked Ugoos if they can look into it.

Hope you are right.
Panasonic does not care much about their customers.

Yes, same method I was doing before. Putting the OTA zip on USB, going to the About-->System Update app.
Now does anyone have any tips for getting Fandango's DV Kodi to work? I have untrusted apps allowed and it keeps on failing for some reason. I'm assuming I should use aarch64, which worked fine on my Shield.
Edit: Maybe a dumb question, but do I need to install the Play Store version of Kodi first and then install Fandango's? I thought it was totally standalone, but maybe I'm wrong.
yep , the 64x didn't work for me as well: I used the 32x version. You don't have to download it from the play store.

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.
sounds similar to my first hour with this device... Once I stopped playing with the colorspace settings, those issues didn't happen again.
What settings did you end up with (color space, resolution, refresh rate)? I have DV enabled and it seems like it’s not even give me a choice of color space.

DV enabled for DV content.
LLDV enabled for HDR10/SDR content. (this force 422 12bits for everything)
framerate match enabled
24hz
resolution match off
everything else to default, I don't touch the colorspace settings at all.

This Ugoos, man
You can add DTS transcoding to the list of things it cannot do properly. Wish I could just do full passthrough, but I have the Sonos Arc 5.1 set and need transcoding capabilities as it can't receive DTS. It works great on the Shield for the most part (Kodi and Plex). When testing this and Dolby Vision you wind up being surprised when the video actually starts playing. The amount of times I've had to reboot or close apps because I don't even know what the hell it's doing is beyond maddening.
All of this really just makes me have more appreciation for the Shield even with its red push and lack of FEL. I knew this Ugoos was a bit rough around the edges, but it's more flawed than I imagined. The AM 6+ is over a year old at this point and as far as I can tell the team that works on these devices is very small. I think it's a longshot that this thing becomes what many of us want it to be.

I always kill apps and processes before I launch Kodi or whatever, I do this on other android devices that have this option also (Zidoo etc) always have and always will.

Can someone please help me with NFS client setup in the Ugoos on Android? I think the issue lies in what exactly has to be filled in the "NFS share path" and "Local name" boxes. Have been trying for many hours entering paths & names with no luck. Every time it says: "Mount error. Check entered data". I don't know what I'm doing wrong.

There are some types of metadata (Block type) in mkv header was added, example for dv-7 profile: dvcC (Dolby Vision configuration) and hvcE (Dolby Vision enhancement-layer HEVC configuration). In source code i found references only for dvcC. In my understanding, the exo mkv-parser must transmit also hvcE meta-data to MediaCodec for EL processing

That is just processing the container, none of the video is processed within the player.
There's no other hint necessary for the EL, it's self contained in the main bitstream and that's up to the decoder to figure out.
Simply telling it that the bitstream *may* contain Dolby Vision is enough.
It's still the proprietary decoder's job to decode the RPU and do the rest of the processing.
Some ignore the EL, some panic when they encounter profile 7 FEL, some don't work at all with profile 7. There's nothing that can be done.

Back at the Ugoos grind instead of working on a Friday lol. I seem to have figured out the issue with transcoding DTS, so that's good news for me at least. I made an 1.16.3 MKV of Power Rangers a bit ago and have been playing around with it in the latest Plex Beta and Fandango's Kodi. I can definitely get Kodi into a playable state, though as others have mentioned it takes awhile before it is smooth. The difference I'm noticing between Plex and Kodi is that Plex is constantly micro stuttering. I also cannot move the playback forward or back in Plex. That can be done in Kodi, so I was able to verify the FEL is playing at the end credits.
I don't really plan on doing much work today, does anyone want me to test anything?

I got PLEX to trigger both DV and Atmos in a MKV container and for the 5 minutes I watched (power rangers), it was perfectly stable. AVR showed lossless Atmos.
but once again when I stopped playback and started it again, back to lpcm stereo and no more DV. Just gotta wait for a ugoos update, I just sent them another email.

Watched a new 1917 mkv in its entirety with Kodi - no fast forwarding or pausing. The Ugoos glitched a couple times at like the 35m mark and then around 80m. It was similar to what it does at the start and eventually fixes itself.
Not sure how to convey issues like these to Ugoos support. We are using an unofficial build of Kodi and they probably need sample files to test.

Ignore this movie
Same issues on any AndroidTV too (No FF or Pausing)
