Dolby Vision now possible through MP4 Mux.

[aboulfad]

Is this very earlier comment from last year still valid: truehd in mp4 ? I extracted using ffmpeg Stream #0:2[0x1100]: Audio: truehd from my Black Panther rip and when mixed with to mp4 along a DV P5 file, I get DV thru InfusePro->ATV4K->LG OLEG65E7 but no sound is detected or played. I did the same test but with e-ac3 and I got both DV/DD+ detected and played.

On another test, the source mkv plays HDR (being DV 07.06) and trueHD is detected by InfusePro. Is this related to ffmpeg CodecID=mlpa vs A_TRUEHD (mkv rip) ? basically the issue I stumbled on was described by @yusesope in this post in 2019 but I couldn't find yet whether an alternative or solution is possible.

The best you can get is therefore an mp4 file with:
DV + DTS-HD MA
DV + DTS: X
DV + PCM

SMH...
sorry to repeat myself but you can't draw ANY conclusion by comparing some videos on youtube with your own TV photo... it's just meaningless and useless (not scientific)...
the only valid comparison here is the shield vs x700 assuming you used exactly the same camera settings which we CAN'T confirm when you put the images like that...

I wouldn't post any picture if it doesn't demonstrate what I try to show
And honeslty I post pictures mostly to encorage someone to repeat the test. Not many volunteers so far

Can you force P-led on X700+LG through Vertex thing?
If so you shouldn't rely on my pictures at all and can see difference by your own eyes

Just play
DV FEL demo with X700 DV on (TV-led) BL+EL+RPU
DV FEL demo with X700 DV on (Player led) BL+EL+RPU
DV FEL demo converted to p8 with X700 DV on (BL+RPU)
DV FEL STDL demo with Shield TV (TV-led) BL+EL+RPU
DV FEL STDL demo with Shield TV (P-led) BL+EL+RPU
Pause on these timemarks, switch back and forward between X700 and Shield both in TV-led and both in P-led modes:
2:18 orange cloud
2:28 noise on sky
3:27 gradients of blurred area in low right corner an overall dynamic range (brigh spots on petals)
6:36 mark, look at yellow eagle beak

After some test I could say there is something very wrong with this demo on X700+Bravia in P-led mode
Shield TV outputs richer colors, brighter image in same P-led mode but for STDL stream. (plus the notorious "red push" of course)

Maybe Shield TV has newest DV composer code
or maybe BR players are not powerful enough to properly merge layers and made some simplifications in process
or it could be RPU processing errors
or maybe it's a Bravia thing?

I dunno for sure.

Also I belive the SM UHD HDR Benchmark demo shows the worse difference TV-Led/P-Led can be
But I can't remember the significant difference in movies.
Maybe there is none or unnoticable.

Early marketing for Dolby Vision claimed that TVs differenly show HDR (due to tonemapping) and with DV TVs will show picture as close to creators intend as possible.
Hell, it actually gets worse
Now we have muted colors and artefacts. In this case better to watch HDR version

Have you checked with your HDFury device to see if the x700 is allowing TV led Dolby Vision?
In the image you have attached above, Stacey says:

Yes, the x700 support both DV format. My Vertex report RGB 8bit (tv-led).

Thanks for confirming.

Finally got my x700
Can confirm the same on my Vertex2.

The 'bug' wasn't exactly what I expecting though. For some reason I thought it would be wrong colors or something but its pretty much full on video corruption. Not sure how else to put it - reminds me of the old 'no signal' grey fuzzy TV days. At first I thought it was the second track or something, but I'm seeing a very small strip on the left where the video is fine? (I say fine, I haven't exactly compared this strip to what it should be ) Is that the same for everyone else? Obviously not important just find it odd that there appears to be this strip with no 'video corruption', I'd expect it to cover the whole video

Anyway - the 'fix video' works great.

Thank you for also confirming.
That's also how it appears for me. Enjoy watching films on your x700.

I still find the easiest, fastest, and least painful solution for Dolby Vision and lossless audio to be the X700 with a tsMuxer mix. If you have a newer model with eARC - kudos. And it plays UHD Blurays. I do give the shield gigabit ethernet and the MKV lossless TrueHD.

Hello,

So I just downloaded Soul mixed in .mp4 with DV I can say it works fine without any hassle on LG Oled C9 with it's native player it turns on the DV and it's not a problem. The sound is lossy but since it's from a stream it's lossy non the less. Is there a way to do the loseless sound with DV if your TV has E-ARC ?

Can you elaborate on this? Googling didnt really give me the answers. Thanks.

- Open a UHD Bluray rip's main playlist file in tsMuxer.
- Mux to .ts (or .m2ts).
- Play the file via a network share or USB from your Sony X700 or your LG OLED.

If you have an LG OLED <=2018 like me, no lossless audio will be passed back to receiver. So I use the X700 for those titles. Also the PGS subs will not work, just use a .SRT in same folder if you need subs.

If so you shouldn't rely on my pictures at all and can see difference by your own eyes

of course, if I could force lldv and see with my own eyes I would have posted a comparison a long time ago.
there's the LLDV Sony EDID option in my first gen Vertex but unfortunately, I'm not able to make it work. All I get is tv-led.

But i do not know why
tsMuxeR desynchronizes the audio with the video. = (

TsMuxer does not desynchronize the audio/video. I merged the Lord of The Rings movies in a single file. I watched all of them without any sync issue.
Tsmuxer is actually my favorite tool to mux seamless branching movie because it properly removes overlapping frames.

Can you explain how you did it?

I have Disc 1 and Disc 2 in m2ts with Dolby Vision when I combine them with tsMuxeR, when Disc 2 (which is connected to Disc 1 + Disc 2) starts up the video audio is out of sync.

I open the "add" rings of tsMuxeR.
Then I click "join", add rings2, select M2TS, and start muxing.

As a result, when the second disc should start, the video gets out of sync with the audio.

Please help.

I always use the .mpls file(playlist folder) instead of the m2ts file so that might be the reason why.
Also, make sure that you use the latest nightly tsMuxer and not the old tsmuxer

So after my latest reply, I decided to give another go to my Vertex. and btw I'm not relying on your picture at all.. I'm just saying that your comparisons with vincent's video means nothing and that you shouldn't rely on it
The firmware was a bit old so I updated it and now forcing lldv works.

I used content(p5 full range DV) that the Shield can actually play properly (not a uhd-bd rip so no red push affecting the output). On my LG C8, I don't really see any difference between the X700 p-led and the Shield p-led.

Been away from this thread for a few weeks so trying to catch up.

I understand that the latest MakeMKV (1.15.4) can now remux a MEL DV UHD Bluray.

For FEL a MEL needs to be created. Is the post below still the preferred method or has it been updated? Thanks

can anybody upload a small DV-file of MKV? so we can test?

Can u do a Soul comparison with the real dv rgb dv-8bit? just for fun.
From both playback devices.
Curious too see on your calibrated c8 to see
If differences of dual tone mapping can be observed LLDV vs rgb 8 like Vincent showed.

Updated program tsMuxeR 2020-12-29 Nightly (x64)
I have done it again as you indicated. I took the .mpls from disk 1 and disk 2 and created a m2ts.
Again there is desynchronization
of the audio with the video just when disc two would enter, as I mentioned.
