Dolby Vision now possible through MP4 Mux.

[yossSP]

Hi all, I'll launch a question to @RESET_9999 and every other member of this forum.

There's a guy in other forum of my country where I'm in who claims that the FireTV Stick 4K (2018 version) can now playback Dolby Vision FEL titles.
As far as I know there's no FireTV that could playback FEL files using the EL layer. From what I have guessed and taking into account that the guy is basing his claim on viewings with naked eye, this device is playing FEL titles as MEL (without using EL layer), what already has a great quality as is.

Could anybody confirm or deny this statement?

Thanks!

can you please confirm if you can FF/RW on the WebOS media player app with TS/m2ts files?

I just tested my C8 with DV TS files and I can confirm that FF/RW works on both PLEX and webOS app.
the file i tried had closed gop though

He's probably talking about quietvoid's new kodi build that can play P7 as P8. Read just a couple comments above.

My 2018 4K stick hasn't been updated in years but it never could play FEL, blank screen.
The 2021 4K Max behaves the same, with latest firmware.

I would love to test a 64 bit build! I'm not sure if its because the Shield isn't compatible with this version, but when I install the Plex addon I just get an endless loading bar with the Plex logo

I've made new builds available here: https://github.com/quietvoid/xbmc/releases/tag/v21-dovi
There are both 32 bits and 64 bits APKs.

The only change from the last build is that the new build also fixes grey letterbox bars when playing cropped Dolby Vision videos for FireTV.

Thanks! You said that you don't use Plex for Kodi - what do you generally use to playback Dolby Vision files on Kodi?

Hi there , I have installed one of nightly master last builds on my firestick 4k and now I get DV when playing a mkv file .

Though when checking color standard output in dev mode in the firestick 4k , i get bt2020_10_hdr10 , when in Disney or Netflix app I get bt2020_10_dovi , which was what I would expect to see also in kodi when playing mkv.

Codec states Dolby vision and my tv gets the flag for DV , however color output in the firestick dev mode looks wrong .

Any thoughts ?

I use PlexKodiConnect or a NFS server.

I have installed your latest build on my firestick 4k max and the .ts files p5, p8 and p7 do not work anymore.
When I try to open any of them Kodi closes. Still works with mkv.
Before this update everything worked perfectly.

Thanks, I also get the crash for .ts.
I'll look into it later.

I found the issue, it seems I can't convert the RPU from .ts for now.
The arm-v7a release was updated, I'll do the other later.
It should fix the crash but .ts profile 7 won't be converted.

Hello,

Your kodi build makes me think about a plex plugin that would convert, on the fly, dvhe.07.06 BL+EL+RPU mkv remuxes to p8 ts.

Would it be technically possible ?
If it is the case, it would be a great solution for lg [c8 -> c2] oled tvs.

for lg c8 / c9, dual layer p7 mp4 remuxes are the best solution, in particular for FEL titles.
I'm ok to make those when there is effectively EL content but for RPU only titles, on the fly plex conversion would be very handy.

set PLEX=download/install plex server and get the transcoder from the installation folder (you can uninstall it once you got the files)

in the TOOLS_READ_ME.txt (Dolby-Vision-Scripts @RESET_9999)
doesn't imply the plex plugin I suggest, right ?

Yes working again but not P7 as you said.
Curious because before, everything was working perfectly, including P7 as I said a few posts before.

I doubt it was actually converting, maybe you were just playing MEL files.

Sorry no. All my P7.ts are from Dovi Fel on purpose. None is from a Mel. And I can assure you that they worked and played perfectly. Unfortunately I did not keep that version.

I don't know but it doesn't add up. I tested a version from the day before and it's also crashing with my test files.
You're welcome to try it: https://mega.nz/file/pZln1IhT#QlMIyPOhW ... 6LidHO1Xqg
This one is the old org.xbmc.kodiDV package.

I don't have the 2023-01-23 build anymore.

Anyways, I have to rework the code so that it works for all files.
This is just temporary.

What is the best way to convert .TS files containing Profile 8 Dolby Vision (converted from Profile 7 MEL) to MKV?

I thought I'd just use MKVToolNix and batch up a bunch of them, but the resulting MKVs only show HDR10 with mediainfo.

If it use tsMuxeR to demux the .TS file first and then use MKVToolNix the resulting MKV files preserve Dolby Vision.

Is this the fastest way to go from a .TS container to an MKV container?

Tried and it crashes as you said.
Will wait for the code reworked version.
Thanks a lot.

MKVToolNix only supports muxing the Dolby Vision config for MP4/MKV (copied from source) and ES (raw bitstream) which is parsed to create the config.
.TS is not supported, you could always make a feature request at the GitLab.

Alternatively, you can try FFmpeg as well.

FFmpeg did the trick. Thank you.

EDIT: Spoke too soon. MediaInfo reports the correct information, but the files only play in HDR.

Forgive me if this is a dumb question but what does MDL mismatch mean? Is there a way of fixing it? I noticed a lot of the incompatible web-dls on your spreadsheet cite “MDL mismatch”, but a lot of the compatible ones do as well @RESET_9999
