Dolby Vision now possible through MP4 Mux.

[LV8HD]

@RESET_9999 I've noticed you are re-generating Dolby Vision for the entire mission impossible saga. Isn't the retail RPU good enough? Are L2 trims automatically generated even in the stock RPU?

ugly large vertical bars on your C2?
What do you mean with this?

Bad uniformity. My G5 is by far the best I've ever seen on any oled.
Try the 5% - 10% grayscale files: https://drive.google.com/drive/u/1/fold ... 2ZGhSXZk_D

On the C2 I see two large vertical bars in all the dark scenes and even on the grey menu when the ugoos boot. That is very annoying.
Also, I checked the DV 10% grayscale again on my C2, and the falling diagonal lines are also there, only in DV but less obvious than on the G5. So, LG TV does more dithering in DV than in HDR10, which explains why DV has no banding and HDR10 has some.

On the C2, 4000-nit MDL content mastered with the old algorithm is heavily crushed, and L1 starts dimming far too early, well below the TV’s actual target. Also, the Mission: Impossible L2 trims are mostly static and don’t contribute much to improving the tone mapping.

Yeah I know. The 5%-10% greyscales are also not great on my G1. I don't mind too much about it though as long as it doesn't bother me too much in real content.

One more thing I noticed on the G5. The RGB white balance trick doesn't work to fix the DV raised black, not even at -6/-6-/6.
It's less raised than the C2 and I can see it only if the screen stay black for at least 3sec so I guess that wont bother me too much (hopefully) and maybe after 100h and a calibration will improve it.

what is exactly the difference between a regular coreelec build vs cpm build?

CPM has an additional engine that can do on the fly conversations. E.g. hdr10+ to DV, even sdr to DV or the other way around. It's very useful for playing content that your display doesn't natively support.

is cpm taking the newest stable versions of CE with every new cpm update?

There's not likely to be any new builds from what I understand. It's a very long story but it has to do with the underlying kernel and the fact that CE is moving to a newer one that won't support FEL on the ugoos. But in any case think of cpm like an extension. It includes all of the CE functionality then it's own on top of it.

No idea why I would need an update anyway. A14 CPM is all you need for years to come on the Ugoos.

This sucks

it's really not noticeable in real content, not even in my perfect dark room. I'm watching the TV show Paradise right now, and it has tons of 3- 4 seconds full black screens. It doesn't stay black long enough for my eyes to adapt and see the faint glow so this is not a problem at all on this TV. My C2 blacks are raised more than that and I could see it all the time in real content.

you won't getting CE updates anymore once you installed cpm build if i'm correct? what if there is a new kodi version? do i need to install that manual and then install cpm build again?

That's not how it works. CPM replaces CE so no you won't be getting any updates from CE once you install CPM. CPM builds are manually installed with update files. Kodi is not some "separate thing" you install. It's built into the image. So no, you won't be getting Kodi updates.

I have a question for you RESET. The other day, someone said that every P5 DV file is supposed to have the following tag in MediaInfo:

Code: Select all

Color Range : Full

Instead of:

Code: Select all

Color Range : Limited

Is this true? I've looked into it a little and I've noticed said tag is all over the place, pretty much every streaming service has both Limited and Full. What files should be Limited and what files should be Full? Should every 4K HDR file be Full or doesn't it matter? Sometimes it doesn't even show at all. What's the deal?

[RESET_9999]

yes, Profile 5 is supposed to be full range but Apple being Apple as always, all their stuff is in limited range. I don't think it matters though

But Dolby Vision from Apple is kinda crap anyways, right?
