Just a FYI...

The x700 and the Zidoo are not processing the RPU correctly when it plays tsmuxer trimmed samples (movie cuts/splits) but somehow decodes FEL correctly.
I know a long time ago, someone here said that he was seeing a difference with its TV internal player and it turned out it was because of the splitting.

samples...

ST-DL TS offsync: https://drive.google.com/file/d/1EKyCtx ... sp=sharing
ST-DL MKV original: https://drive.google.com/file/d/1gRBqz7 ... sp=sharing

at the complete end of the sample (58sec) there's a brightness adjustment visible on the C8 and Shield but not on the x700 and the Zidoo.
If I don't split the file but still delay the RPU, then the zidoo and the x700 also have visible brightness changes.

Hi @RESET_9999, I will be glad if you answer my question
As you have tested Chromecast with Google TV, do you recommend it for FEL movies? Mostly I convert them to MEL and make profile 6 DV and watch it with webos plex app (my tv still supports profile 6). They look really nice but I don't know how much quality I sacrifice for converting from FEL to MEL. Is buying chromecast for only FEL movies really worth it or is there no significant diference between MEL and FEL? I wanted to know because almost all technological products are expensive in my country.

Well if don't care about not having lossless audio, then yes the Chromecast is a good mediaplayer for FEL DV mkv but one problem: with my LG C8, I'm only getting LLDV which is very strange because I know this device can do tv-led DV but somehow output lldv by default.

Honestly, I used to think that there was a big difference between FEL and MEL but after comparing a lot more movies, the difference is very small on our 10bits TVs unless the studio(EG. total recall) did a poor job encoding the base layer. I would probably fail a blind side-by-side comparison test on most movies.

I still prefer to watch FEL DV on my x700 though, just for the peace of mind :)

Thanks.Then I think I'm gonna pass it until 12-bits TVs out :)

I see a bright pink flash at the end if thats what you mean (similar to the artifacts I was mentioning in the encode problems I'm having, just not always pink)

This was on a Tivo Stream 4k - which BTW I can confirm processes SL DT FEL files as I took the first 5 mins of 10 cloverfield lane BL and put first 5 mins of EL from Cabin in the Woods and it was clearly showing the ghost image of the color FEL video playing over the BL - I just saw one person ask about that device way earlier in the thread and I don't know if anyone gave him an answer - it does struggle to keep up over wifi though with only 45mbps hevc encodes so go wired if you use this (network is fine, and CCwGTV has no issue over wifi) edit -might be the chipset as well S905Y2 vs S905D3 I'll have to test it wired sometime I just don't wanna take the USB C hub from the Chromecast out on the patio right now it's awkward to get and put back where it's hidden away - the tivo has the best android tv remote though hands down - they just screwed up making it toy size instead of the size of the regular tivo remotes (or smaller than that but bigger than they chose)

it's normal to see the flash with the version that is out of sync. that's the goal, we want to know if RPU is used properly.
If you're seeing that on every DV encoded file, it means the Tivo decoders go out of sync. I noticed that on the UGOOS AM6 as well, ghosting in FEL playback even with remux files.

Interestingly though, if you're seeing ghosting with fel titles, that means this device has 2 decoders and is one of the few media players that supports FEL.

Yes I edited though to mention it can't keep up but don't know if the older chipset or cause im trying on wifi - will have to try wired later

So could the 'color artifacting' i'm seeing just be the rpu/el and my encoded layer aren't 100% frame for frame lined up (even though no errors thrown)? because I tested on more than one player and it was reproducible on diff devices - so I doubt both/all decoders are crashing/erroring out at same part - that would be more a file error

I'll see if I can mux out one obvious one for upload

Edit yes that has to be what it is - because when I test my FEL test file I used on the Tivo on a device that doesnt to full FEL I see the same 'color artifacting' that you mention is RPU/brightness related

Double edit Tivo Stream 4K is playing 1:1 full FEL p7 muxes fine for me - erroneous test files were what was tripping the decoder/the device up

Playback on the Tivo, you can see the 'g' from the Lionsgate logo in the FEL rendering to the right of the Paramount Mountain in the BL at the end of the clip (there are other obvious things at the start of the video too over the water but the video doesn't capture what you see in person with that):

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?

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.

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.

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.
