Dolby Vision now possible through MP4 Mux.

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.

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

[DylanValenti]

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

[mulucy]

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.

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?

[bedders]

I have a question about profile 7 DV and MakeMKV. Am I right in thinking that if a FEL UHD disc has been ripped with MakeMKV then the it generates a single video track and the enhancement layer 1080p track from the disc is somehow interleaved along with the main video track?
If this is the case, how does one tell from the resulting MKV that it contains the enhancement layer since MediaInfo will show only a single 2160p track?

PS sounds like the Ugoos AM6 Plus is the way to go for DV playback. Ordered one today

But for me it does not play at all.. all I get is a black screen and a spinner, both in Emby and from usb disk using the builtin mediaplayer.
Something wrong with the above steps or commands?
Any help would be nice

Here is HELP

I googled for the last few hours and I could not find an answer to the same question. I muxed the BL and EL video tracks with the command:

Code: Select all

mp4muxer --dv-profile 7 -i BL.hevc -i EL.hevc --media-lang eng --output-file BL+EL.mp4

And for me the movie on my LG C9 was also not playing, showing only the "spinner" all the time. After some investigation I found that the issue might be here. After muxing the tracks into one MP4 file: BL+EL.mp4 - the EL track (2nd one) was described as:

Code: Select all

HDR format                               : Dolby Vision, Version 1.0, dvhe.07.09, BL+EL+RPU / SMPTE ST 2086, HDR10 compatible
Codec ID                                 : hev1
Codec ID/Info                            : High Efficiency Video Coding

And I found that in order for a Dolby Vision MP4 to play correctly on LG C9 it has to be like this:

Code: Select all

HDR format                               : Dolby Vision, Version 1.0, dvhe.07.09, BL+EL+RPU / SMPTE ST 2086, HDR10 compatible
Codec ID                                 : dvhe
Codec ID/Info                            : High Efficiency Video Coding with Dolby Vision

So I needed to find a way to change hev1 into dvhe inside the EL video track inside the MP4 container.
I could not figure out any command or switch in mp4muxer or m4box to do so (there might be one) so I decided to go a different way.

I downloaded HxD Editor
https://mh-nexus.de/en/hxd/

Then I opened the BL+EL.mp4 file and I went to menu Search -> Find -> Search for: "hev1" + Case sensitive (checked).
Inside an MP4 file without audio tracks (could be the same inside a file with audio tracks) it was the 2nd search result.
So after I found the first "hev1" occurance (line 01E0) I looked for the 2nd one "hev1" (F3 - Search next) which was line 00023AF00. My guess was that the video streams were written in the MP4 file in the sequence: BL and only then the 2nd one is EL.
So then I just overwrote the 2nd occurance of "hev1" into "dvhe".





After that I just saved the file File -> Save. HxD Editor will create a backup for you so you don't need to backup the file before in case something goes wrong.

After opening Plex on LG C9 voila... Dolby Vision! No more spinning wheel.

And in the MediaInfo I found:

Code: Select all

HDR format                               : Dolby Vision, Version 1.0, dvhe.07.09, BL+EL+RPU / SMPTE ST 2086, HDR10 compatible
Codec ID                                 : dvhe
Codec ID/Info                            : High Efficiency Video Coding with Dolby Vision

I hope someone will find it helpful.

First of all, greet everyone and thank the work and effort made so that we can reproduce DV. I would like to know, if possible, that someone explain step by step, how to create a m2ts or ts that maintains the two layers of DV in one file and is playable on a Lg CX tv. I have read almost 300 pages, but the information is confusing at times, and somewhat difficult to understand at certain points. If someone would be so kind to describe the steps and share the necessary tools for the job, since these also change and are constantly updated, to know the necessary versions of each program. Greetings and thanks again. Sorry for my terrible English.
