Try latest Vimu Player 8.90 from this page: https://4pda.ru/forum/index.php?showtopic=777309

Hey that Player works really very well. I have some stuttering when I select a Dolby Atmos soundtrack, but that's doesn't really matter to me because I don't have a Atmos sound system.
Thanks for the tip

One other thing I noticed, DO NOT fast forward/rewind or skip through the movie because it unsync the FEL. You don't really see it in the movie but every time you skip to the ending of Power Rangers, there is visible fel ghosting.
same behavior on plex and kodi ... no problem on the x700

Check "Eagle" scene from SM UHD HDR Benchmark (around 6:34 time mark)
Pay attention to beak color

It sure seems to affect more the scenes where FEL adds a lot to the image and I guess FEL doesn't add much to the MI scene that I compared last night because there's indeed a noticeable difference in certain scenes of the SM disc. Especially the red flower frames where it's very noticeable. But not much different on some other scenes like in the Eagle one though. lldv seem to be slightly more saturated/darker.

Gives your description, I think you might be transcoding. If Plex doesn’t think your system can handle the native audio, it will direct play the video and transcode the audio, which totally breaks DV. I spent half a day on this once on my Shield because ... I connected BT headphones and this issue broke my DV.

thank you. I'll check the audio settings in plex. I use the same plex server on the shield and there's is no audio transcoding
DV works with ts and mp4 files though.

EDIT:

yes, that's the problem. My DV MKVs have Atmos audio and plex try to transcode(because there is no ac3 core in truehd /mkv) so DV doesn't work indeed. If I select an AC3 track before playing the movie then DV is triggered. I'm still getting 2.0channel even though plex says direct play and as I said, same plex server on my pc that works with the shield.
DV works much better on plex... i hope they add lossless support there

Similar observations.
But I guess if spares was originaly done in p5
There would probably be no diff.
Can u do a true p5 LLDV vs p5 rgb-8dv comparison?
I don’t think Vincent tested p5 actual file I know he tested streaming vs uhd disc.

this is not UGOOS related but I just learned that if you remux DV to bluray folder structure with tsMuxer and you put the files in the root of an USB drive, the Sony x700 is able to play it in dolby vision with chapters, working FF RW for long movies and no more green screen bug when you stop playback.

I'm trying this out and got an unknown USB device error. In tsMuxer do you choose to output it as blu-ray folder or AVCHD folder? And do you leave the M2TS file in the BDMV\STREAM folder or put the M2TS file in the root directory of the USB drive? Thanks for any extra guidance with this, I'm excited to get this working.

choose bluray folder in tsMuxer and put the BDMV and CERTIFICATE folders in the root of the USB drive. The BDMV folder will show up as AVCHD on the x700 and you play that folder.
I'm not sure if the CERTIFICATE folder is really needed, I never tried without it.

I'm still getting 2.0channel even though plex says direct play.

I did more experimenting with the UGOOS & plex:

1- TrueHD, AC3 and EAC3 are all sent as LPCM 2.0 in PLEX even if it says direct play.
2- DTS and DTS-HD are sent as LPCM 5.1 in PLEX
3- For Kodi my vertex says ''Audio Bitstream'' and my AVR reports the proper audio for every format.
4- strangely, while testing plex with many many of my movies and without changing anything to the settings, two times I've seen my vertex reporting ''audio bitstream''. One time with EAC3 atmos (avr showed ATMOS) and one other time with AC3 (avr showed DD).. stopped playback, re-played and boom back to lpcm 2.0
so it looks like audio bitstreaming of any lossy or lossless format is not working on PLEX. Hopefully, future updates can fix that and allow lossless passthrough because FEL DV works very well on PLEX. The ugoos have great potential to be THE device we all wanted to have.
5- Composite kodi addon, you can play movies from your plex library. DV mkv and audio bitstream works too but it seems FEL playback is not stable.

As for HDR10 being sent in 8bit when DV is enabled:
the fastest method is just to enable LLDV when you want to watch HDR10/SDR content and enable tv-led DV for DV content. Otherwise, if you just turn off DV, you also have to select 422 in colorspace settings.

Thanks, I was doing that part correctly and got it to work now trying something else. It's a new USB flash drive and I had it formatted as NTFS, so thought maybe it needed to be exFAT instead for the folders trick to work. I do have other USB flash drives formatted as NTFS that work just fine with MKVs and other M2TS files though.

After I formatted it to exFAT I put a small MKV file on it just to see if it would work, which it did and created the buda folder. I really should have tried that first before formatting it to exFAT though as I'm thinking it's maybe because there was no buda folder that it didn't recognize the BDMV folder structure. Maybe some other video file needs to be on the drive first in order to create the buda folder, whatever that does.

Hi,

I'm brand new to this and I tried to remux the file into a Blu-ray folder and I get this error:

"Reading buffer overflow. Possible container streams are not syncronized. Please, verify stream fps"

For what it's worth I get the same issue when trying to remux the file into a TS or M2TS file as well. I'm not sure what I'm doing wrong..

are you using the right tsMuxer ?

Yep, this was the issue. I downloaded the nightly version and it worked like a charm. Actually figured it out before you posted but thanks anyway!

There is no combination of settings in Vimu player on Minix with Ugoos firmware that triggers Dolby Vision and HD audio, audio is either stereo or multi channel pcm, sounds like the same problem as Plex.

[RESET_9999]

I sent an email to ugoos regarding the audio bitstreaming on PLEX. I encourage everyone else to do the same

support@ugoos.net
eugene@ugoos.net

I think the problem is UGOOS and not the plex app

[RESET_9999]

https://github.com/moneytoo/Player

this player looks as stable as plex for FEL playback and at least gives you 5.1(LPCM) audio with any format.
Also, there's no fel ghosting when you FF to the endings credits of Power Rangers.
Not sure if this player can access network libraries though.

Apparently, it is an upstream kernel issue from Amlogic. The Minix U22-XJ firmware is in the same boat, so we should be thankful that Ugoos has at least gotten lossless audio passthrough working through Kodi's IEC packer, which Minix have not.

It doesn't look like something Ugoos can fix themselves. If anything, we should be asking them to fix the DV colourspace issue (the DV on/off setting should be able to be toggled for DV content independently from the output bit depth/colourspace settings for SDR/HDR10 content), and working with the maintainers of the Kodi DV build (fandangos, quietvoid) to help them get the FEL stability on par with Exoplayer (which is what Plex is using behind the scenes).

Yes, this player is using the same Exoplayer backend as Plex, so you can expect that its media-playing capabilities are exactly the same.
