Dolby Vision now possible through MP4 Mux.

You don't need to switch, just use the Android Kodi 19 DV build to play everything - it works fine. I've actually got a Minix U22 sitting in front of me that I'm going to test today so I'll let you know shortly how well it works.

[mattmarsden]

I've also noticed if you completley quit Kodi and and restart it and play a FEL mkv straight away they play a lot better. Hopefully the build will be refined soon.

OK, Minix U22 on latest firmware does not work properly with the Kodi DV build, it will only allows selection of resolution 1920x1080p 60hz. I believe it can be flashed with the Ugoos firmware but I havn't tried that.

Looks like Memory Management issue with Kodi
With my AndroidTV, the FEL/MEL mkv playback is a lottery. DV MKV WEB-DLs playback is fine though

real web-dl single layer DV of Stranger Things season 3 play nicely.

This is very old but where did you find a DV Web-DL? I've never seen that, only DV from Blu-ray rips.

There are 3 single layer DV profile 05.06 web-dl releases circulating on the web.
Stranger things S03
Mandalorian S01
Star Wars New Hope (which I successfully added a trueHD Atmos track)

the last two can be found on one of the most known public torrent websites. ST can be found on a Russian tracker.

I’ve searched high and low for the Star Wars Dolby Vision, but couldn’t find it on any tracker I know of. Any other tips? (I know it’s been a while but any help would be much appreciated )

[DaMacFunkin]

OK, Minix U22 on latest firmware does not work properly with the Kodi DV build, it will only allows selection of resolution 1920x1080p 60hz. I believe it can be flashed with the Ugoos firmware but I havn't tried that.

Hi , do you have more information on cross flashing the U22, is it exactly the same hardware / Memory?
Thanks

The original Ugoos fw is not working, you need to use this version: https://4pda.ru/forum/index.php?showtop ... y103863672

How can we tell Minix is processing the colors correctly and plays the second HEVC stream with EL layer like a regular Blu-Ray player? For a long time, we thought the same thing with Shield, but Shield discards the EL

I don't know about the Minix specifically, but there is proof for the Ugoos AM6 Plus, which uses the same S922X-J SoC: 1 2.

In theory, these AMLogic chipsets have hardware support for FEL processing.

The picture shows LLDV which is player-led DV I assume? Does the UGOOS support tv-led DV considering the issues with player-led DV.

Supports both.

The hardware is definitely there, and Ugoos is pretty good with software and support ( at least they have a good track record). My only concern is whether we can compare the picture differences side by side between Sony X700 and AM6 Plus on the same tv. We have to make sure it's not discarding the EL like Shield does

[mattmarsden]

The Ugoos is 100% using the FEL. As an example if you look at the end credits of Power Rangers if it is discarding the Fel they look very grey but if it uses the FEL they are white - they whiteness of the end credits is actually in the FEL. I demuxed the FEL of Power Rangers to check the FEL! It also gets the noise in the picture if you use the test with the wrong FEL muxed in. I've compared it on my LG C9 with the C9 playing a the FEL mp4 and it looks the same.

Hi Matt, Given the current state of the Ugoos playback of DV, is it currently functional with just a couple of glitches, or does it really need a lot more work?

Have you tried different buffer sizes in Kodi?

Also has anybody tried the Mininx with custom firmware, it’s £30 cheaper in the UK than Ugoos.
Thanks.

[ArArdin]

Somebody know when the Ugoos AM7 will appear and how the specs will differ from the AM6 Plus?
