Dolby Vision now possible through MP4 Mux.

[Mattl0]

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.

Thanks !

Here is the ouput of the contentof some files that control am6+ behaviors with dolby.

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.

are the WEB DV-rips single layer or dual layer on the internet? for example series dv-rips of diney+?

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?

Pr. my understanding it will not, but i am not totally updated on the subject, as this solution is good enough for me, given i don't have THAT many DV movies.

Thanks for your response. I have just recently ventured into ripping my 4K UHD movies and have a DV enabled TV but older (but working without any issues X800) and still exploring my options for DV playback device. Currently nVidia Shield Pro is my top choice but since it is already 2 year old since release I will wait to see what features will be added to its next iteration and potentially get the 2019 version for less financial outlay.

Yeah, i have had a shield pro 2019 since launch as well, and it does pretty much everything very well. But once people here told me about the red push issue, i started noticing it haha. Fingers crossed it will be fixed eventually (and less likely: add FEL support) Probably wouldn't have bought the x700 at full price though. Also it is possible that there will be a shield 2021 refresh, possibly even with a fresh chipset. We will see.

Hey guys, been having some trouble getting certain DV files to playback on my Sony XG9505 and I think I have identified the issue as being that my TV can't play profile 7 FEL but can play MEL?

I done some testing and I got the following results, which confused me at first as it seemed like since all the files were the same either all would play in DV or none should, but then stumbled onto a list on I think blu-ray.com identifying which releases were FEL and MEL and it seemed to line up with what I could and couldn't play.



Am I right in saying that if I extract the HEVC stream from my rips I can use dovi_tool by quietvoid (dovi_tool -m 1 convert filename.hevc) to essentially convert the FEL DV into MEL (which in reality is just removing the enhancement layer?) and then mux the HEVC file back into the MKV I should have a working MEL release with HDR10 fallback? Since the MEL includes dynamic metadata, it should also still be an improvement over just HDR10, but not quite as good as full FEL playback?

[Snickers333]

Guys i tried to read into that but couldnt find answer.
Is it possible to take Bluray profile 7 DTDL and convert it into STSL profile 5 cause it seems that my LG CX is only capable of playing this instance of DV files. I tested and its working with rips from ex. Disney+ Falcon and Winter Soldier DV file from rarbg which is indeed STSL profile 5.
Thank you so much
