GoT episodes are in FEL.
On C7, C8, C9, the best option is to make DV dual layers mp4 files (dvhe.07.06) and to play them directly with the LG built-in player.
For each episode, extract BL, EL and audio files with tsmuxer, then mux the mp4 file with mp4muxer.
The result is almost 1.8 TB for 98 files (mp4 + srt files)
Thank you!

It’s a real shame the situation hasn’t improved since I first started this. It take so damn long :?

DV discs look so good, but my UHD player died and my Xbox Series X doesn’t support DV discs (only DV streaming). Is there any hardware that reliably plays original DV disc rips yet?

These days most of my movie buying is via Apple Movies because of the convenience but I miss the quality of discs and owning a physical thing.

Hi. Sorry to ask something already covered in this thread, but I haven't been able to figure out the latest/best info.

Back in Dec 2020, I started using scripts from this thread to convert Dolby Vision UHD discs (Game of Thrones) to DV MP4, but I never finished the process.

What's the best option currently to convert these discs to a DV file that will play on AppleTV with LG C8 — or using LG C8 built-in player?

Are you sure these tvs can play FEL correctly? Some people on reddit say if you watch FEL title with internal player, it is downgrading to MEL.

As far as i know any Lg internal player can play "correctly" mp4 dv dual layers, maybe for like 30mins or so and then everything collaps.


Anyway, im using yusesopes tool trying to convert FEL power rangers to MEL using the option "mux and convert to mel" but after cpnverting to m2ts i get a hdr file...tried with other movies and i get the same, anybody know if theres a new way/process to do it?, using hevc files straight from full rip and last yusesopes tool.
Thank you

For me personally my C8 will always stutter and freeze when playing certain FEL titles such as John Wick 3 and 1917.

It doesn't really matter whether I mux them into MP4 using mp4muxer or TS/M2TS using tsmuxer.

I think the FEL layer is being processed though.
The SoC just doesn't have the horsepower to decode it.

So for me the only way to get them to play is using yusesope's tool with the "mode 2" flag.
It will ditch the enhanced layer altogether, turning them into profile 8 (BL+RPU).
But at least they'll work in any container then.
Also using tsmuxer allows you to keep the hd(lossless) audio as well for preservation.

This is incorrect if the display maps the colors and dynamic range as it should. If it doesn’t that’s on the display you’re using, not the player.

Colors within any of the color gamuts will be completely identical whether they be Rec709, DCI-P3 or BT2020, up to each of their limits of course. So putting a Rec709 source into a wider P3 or BT2020 container should look and display identically when the gamuts are mapped properly since Rec709 is smaller than either of those wider gamuts. It’s not supposed to stretch the colors at all and if it does then your display is doing it wrong, not the source.

I have both an X700 and an X800M2 as well as an AppleTV 4K and they don’t have any of the issues reported with my displays because they map the signal correctly.
Forgot I even wrote here, but you are incorrect. It won't be the same, even if the color mapping is done correctly, the profile settings of the TV are completely different from an SDR profile. Also, from it's not "supposed" to stretch the colors to how it actually works, it's a long way. Even if does work as you think it "should" work, you still have maxed out brightness settings and all, as the TV is running under a DV settings profile. So yeah, it's still crap and sad to not be able to make the player recognize DV content automatically like all other players from other companies do. But then again, it took Sony years to get DV sorted out for their TVs.

Proof that they are wrong: You can clearly see the 2 différents layers on my C7.

Of course a dv dual layer can be played in the c6-cx, will read both layers, but it wont hold for long, usually is buggy, choppy or will just stop after 40mins or so, this year c1 cant though after their first update. Isnt a smooth playback, test it with any Fel movie, 2hours long and enjoy.

Question:

Is is better to demux - mux with yusope’s tool, or with makemkv? In term of quality. .
I saw somwhere that makemkv as thw tendensy to ignore nals.

Is there a tool like yusope’s one …that does all what this tool can do and more?!

To get good dv p7 quality on my c1, I need to send stdl (ts or m2ts) to the native com.droidlogic.videoplayer’ player on ugoos6b .

The difference between the native player , and orher player like vimu etc.. is night and day

How do you send video to the native player exactly?

Hello everyone! Immediately I apologize, I do not know English and I use google translator.

I need to replace the audio track in the mp4 file with Dolby Vision Profile 5.
I used this program (https://github.com/DolbyLaboratories/dlb_mp4demux) to extract a .h265 video track from a file.
I used this program to create the file - https://github.com/DolbyLaboratories/dlb_mp4base.
Used this command:

mp4muxer.exe --input-file track1.h265 --input-file track2.ac3 --media-lang eng --output-file 00000_P5_f.mp4 --output-format frag-mp4 --mpeg4-max-frag-duration 2000 --dv-profile 5 --overwrite --mpeg4-comp-brand mp42, dby1, iso6, isom, msdh

But I get Error: rap distance larger than max fragment duration

If you do not use fragmentation, the file is created normally, but I cannot use rewind when watching it on tv.

Help me please.
