Dolby Vision now possible through MP4 Mux.

[Poker354]

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.

Interesting thought,

A majority of my Dolby Atmos DV discs have 7.1 and DD+ can do 7.1 Unless i missed the memo that DV MP4 or TS files doesnt like 7.1, why aernt we using it if Dolby Atmos or Dolby True HD tracks are in 7.1 and the Dolby Scripts downgrades it to 5.1?

why are we losing those two channels cause i do have a system that can do 7.1 and DD+ can have 7.1?

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.

ffmpeg doesnt support 7.1 audio.
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)

Also, the 7.1 EC3 from bluray disc doesnt work, it plays the 5.1 core on my C8/C2.

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.

[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.
