Dolby Vision now possible through MP4 Mux.

ffmpeg doesnt support 7.1 audio.

That is not true. ffmpeg supports:
7.1 trueHD/atmos copy
7.1 trueHD, flac, PCM copy and encoding
6.1 alac encoding
7.1 eac3/atmos copy
5.1 eac3 encoding
5.1 ac3 encoding
I’m not familiar with all the DTX sound.

DEE does but I'm not able to get 7.1 audio from my C2 internal player to my AVR (might be because my avr is ARC)

ARC should be able to do 7.1 eac3/atmos at best, through HDMI 2.0
7.1 eac3 without atmos through HDMI 1.3
eARC is only needed for TrueHD and PCM

In case anyone want this, it's from https://zhuanlan.zhihu.com/p/106809463. I don't own it.

I'm using the recently purchased x700 with the lg c9 oled and it sucks if it turns out the x700 is unusable again.

C9 has the old DV engine so you don't have this problem.

How old are we talking about? I got LG Electronics OLED55B7A in 2018, do I need to worry about this issue?

lol we are talking about my script and EC3 encoding.. I know ffmpeg can copy 7.1 audio

well 7.1 EC3 without a core doesn't work on my C8/C2 + ARC AVR , so I don't know
7.1 EC3 with a core plays fine but only the 5.1 core.

btw , the answer to your hybrid rpu question is also in my script . there's tutorial video. they were made with an older version of the script though.

looks like the CX or older are fine

[RESET_9999]

looks like the Sony X900H also have the bug:

eac3 can have a core? I don't know that, I thought only TrueHD should have a core.

yes, a core is mandatory on bluray disc for EAC3.
i made a demo with a couple different audio you can test (i messed up the last part of the demo though):

Ugh ... I've just unboxed my x800m2 and I can confirm the bug on the LG C1. The LG C1 internal player looks fine.

[sergonnn111]

Hi please give source where i can get makemkv nightly

[chros]

it's not a player bug.
It's Dolby's faulty implementation in newer TV.

Oh so the new engine is faulty? Then I guess Dolby and LG have to work together to release an update on the newer TVs. I will try tagging Vincent from HDTV Test on twitter so he can be aware of this. He has good contacts at LG.

Thanks! Then just link this post, it has all the bugs we know so far about 2022 LG models.

And let's wait for a miracle!

I’m not sure I’m experiencing this bug. LG CX with Sony X700 and Shield Pro 2019. Testing the videos back and forth (ts on Sony and mp4 on Shield) I could easily see the changes on both. The shield might look slightly better but I easily see them as well on the x700.

yep, CX looks ok. lucky you

please try the cmv4.0 version on your Shield(or TV internal player) and tell us if you get L8 reaction.

I've tried this on my LG C1 (latest version) using x800m2 (latest firmware) and no visible changes for L3 or L8.
