Dolby Vision now possible through MP4 Mux.

On most movies the Zidoo Z9X will do you fine, if you absolutely feel you need full FEL then Ugoos am6+ with patched Kodi, but it is a real flaky box tbh.

Ugoos released a new firmware today (https://ugoos.com/rc-firmware-update-v0 ... -x3-models), with video codec and stability fixes.
Might be worth checking out. I hope this update is a sign that the rumors about the abandonment of the AM6 are not true.

Update with small fixes, nothing changes with DV in mkv troubles (Kodi 19.x from Kodinerds / fangos): sometimes "ring of death" during start movie (repeating stop/start may help), lags/freezes/glitches for 7-profile (depends of release - some has 1-2 during play, some - every 2-3 sec )

Pretty sure it is afr issue. With afrd installed as a system app i do not have these trouble. I also use vimu player.

I just wonder why it is sending 444 to the tv and not rgb for tunneling.

Edit : I was able to capture this from adb . So maybe sending 444 ycbcr/rgb is the same?

I am also wondering if my lg b6 can do tv-led since I have not been able to find the info on the web. Everything I have seems talks about lg c7 to 2019 lg oled.

[userr]

Sooo, is there any box/player that can handle FEL correctly that also has ability to connect to a PLEX-server?
Landscape seems like theres a ton of alternatives but all fall short

I laid out some of the FEL-specific issues I've been experiencing on the AM6+ in an email to Ugoos. They replied back very quickly saying they are trying to reach out to Amlogic for assistance as their hands are pretty tied when it comes to those specific DV-related issues. Sounds like a longshot, but maybe a tiny bit of hope left.

I am starting to think the am6+ can't decode fel, and can only output lldv dithered at 8 bit ?

True Dolby vision is tunnelled RGB 8 bit - LLDV is 12 bit.

Ok, so i found a 2nd hand X700 for 90$ and couldn't resist finally getting proper(?) FEL playback of backups

Of course all my backups are .mkv, as i thought that would be the golden solution... Guess not So thanks bits and pieces from this forum, i think i've narrowed down the procedure to convert DV .mkv to the format the X700 accepts off USB, and decided i would share it here for reference:

1. Demux the .mkv with gMKVextractGUI.
2. Use EAC3to GUI demux feature on the .thd file output from step 1 to create a .thd+AC3 file tsmuxer will accept (not needed for DTS or lossy audio?)
3. Run demux.bat from yusesope's BETA (not gamma) 0.0.4 tool and drop the .hevc file produced in step 1 here.
4. Put the BL.HEVC & EL_RPU.HEVC produced in step 3 & the .thd+ac3 file produced in step 2 (in that order) in tsmuxer (i use the nightly from 30/4), and tell it to output to a blu-ray folder.
5. Rename the folder to AVCHD and put it in the root of your USB storage for the X700.

Regarding subtitles, i add the .mkv to tsmuxer and select the subs i want. Maybe they can be used from gMKVextractGUI as well, but i had some none working ones on my first attempt, so playing it safe as i know they work directely from the MKV.

Any comments if i made a mistake somewhere, or made it overly complicated would be appreciated

Hi. I have OLED C8 which, from my understanding reads profile 7 FEL and MEL Dolby visions files encoded in MP4s.
Is it possible to take the newer DV dual layer mkvs and re-encode them in mp4 whilst keeping all the info (except Atmos?).
I feel like this has been asked before but all I could find was a tool to convert FEL to MEL which isn't what I am trying to do.
Any help appreciated.

Will your X700 also play the DV .mkv file with lossless HD audio tracks (DTS-HD or DTS:X or Atmos) via network share? Or this procedure you mentioned only works of connected USB drive?
