Dolby Vision now possible through MP4 Mux.

[deadchip12]

So, it's confirmed that at this stage DVDFab made single layer DV is basically a fake? Are you sure?

Since I haven't done any of the testing myself, I can't be 100% sure, no. but far smarter people than me have tested it multiple times in multiple ways and they all seem to reach a similar conclusion. this is also why I have been so hesitant to make a tool for easy single-layer mp4s. I don't want to perpetuate any pseudo tech. I'll stick with true dual layer, and my next update should allow for hd-audio + atmos in the mp4s it creates.

It makes sense. Why Gemini Man, made using the DVDFab DV Single layer, has a choppy playback and it requires a good HDMI cable, whereas the same movie in HDR10 works smooth? I am not trying to argue with the fact, to be honest. Genuinely curious

From my experience and some other's here, Gemini Man DV single layer does not have choppy playback because it is essentially hdr10 version which runs at correct 60 fps. It is Gemini Man DV dual layer that has choppy playback because it is true DV and somehow the remuxing process messes with the framerate or whatever.

so you play your media in dual layer,and may i ask how you play that too your tv? are you using something like plex?
a nvidia shield tv? a nas? i'm curious. mainly because i have a shield tv pro and from what i heard they can only play
single layer?
I really could use a summary of this topic its getting so big
from what ive done so far is use a usb drive connect it too my tv,and play with the local media player,which works but i wish too look for a more elegant solution...

LG TV's (series 7/8/9) Plex app can direct play dual-layer dv movies no problem. The newer models also support e-arc so it can passthrough true-hd + atmos / dts-hd ma + dts:x. If you own a different supported TV and are stuck using its usb media player, you'll still get Dolby Vision ok, but unfortunately the audio needs to adhere to regular arc limitations (dd+ eac3 at best).

i'm using a lg SK7900PLA https://www.displayspecifications.com/en/model/d611126b idkit came out in 2018,
i have played via the plex app from the lg store dual layer dolby vision files,but i need a way that it doesnt constantly buffer,i'm guessing thats because its software encoding or something instead of hardware which is only for premium users

ugh ya, software encoding is sketchy. Also to clarify I meant the LG OLED TV's. They pack a mean processor that can pretty well handle anything these days.

guess i'll be making myself a tiny little pc,a powerfull nas or just stick to usb sticks for the time being ^^'

It was the same with my Apple TV. I had to get a better cable and change the HDMI connection to RGB full to make the DV work.

Do Sony TVs (XF90 or XG95) play the dual layer DV MP4? They're Android TVs, so I'm not sure if there is a built-in Video player I can use.

Any inputs welcome before I buy a Sony.

[daddy]

I think the Sony dv support is the worst.

Sony implemented a modification to Dolby Vision support by which most of the processing for playback of content with this kind of high dynamic range formatting is offloaded to the device from which it came from instead of being done inside the TV itself. Thus the need for complementary updates from streaming device makers. Why Sony chose this approach is still unknown but it could be because they wanted to make their Dolby Vision update as lean and easy to implement as possible.

Philips 804 is an android tv with a built-in Video player that can handle dual layer dv.
This is surprising that nobody tried to backup this android application, to try it on another android device

[rosavanwinkle]

What i don't seem too understand is why Plex allows me to play Dolby Vision movies via the plex app on the LG store but not via the plex app on my shield pro 2019.
if you wish for more info about my files i got a ton more Dolby Vision movies on my pc
Is this a licence issue?

Thanks for that link. I've found that single layer DV plays okay in Sony Android TVs but as the article suggests they will not play dual layer remuxes.

Shout out to anyone with a Philips 804 for a backup of their native video player app.

Yes that is correct its a licencing issue as LG opted for the Dolby Vision Dual Layer licence which Plex and Xplay both use the included media player that is built into LG's tvs iirc. Nvidia must have opted for the single layer only licence which frankly sucks as you can't playback the mp4 DV DL movies on the 2019 Shield as it will play as HDR10 only. What is sad is that the 2019 Shield has the raw power to playback all the DV DL movies and even Gemini Man Dolby Vision DL at 60fps.

The Shining (74.3 Mb/s) has a similar bitrate to Gemini Man (81.0 Mb/s) instead of 59.940fps its 23.976fps and it plays just fine over wireless ac. The stream size on The Shining is actually larger then Gemini Man so it appears that the wireless isn't the bottleneck at all. For some reason they choose to do a Full Enhancement Lay(FEL) on Gemini Man which I remember reading somewhere that is not recommended by Dolby at all because of the power needed to play it back. I believe that I just confirmed that it has to be the LG Alpha 9 SoC not being able to playback HFR 60fps HDR10/Dolby Vision correctly. The Shield 2015/2017/2019 will playback the HDR10 60fps movie just fine over gigabit Ethernet. I can not completely rule out that it still could be that the 2 year old Dolby mp4muxer isn't handling 60fps DL DV correctly though but even using the DVDfab DV DL it still won't play on LG tvs without the stutter.

[rosavanwinkle]

on the plex forums someone started this threat might be worth a read:
https://forums.plex.tv/t/feature-reques ... /532651/18

aswell as on nvidias site:
https://www.nvidia.com/en-us/geforce/fo ... n-support/

from what i'm reading their exoplayer seems to be updated too be able to play dual layer,but i guess its still a licence issue,maybe someone can make a player that is compatible but i highly doubt it. i'm pretty disapointed in nvidia myself creating such a high end device and then opting out of dual layer :/

Gemini Man HDR10 plays fine at the correct 60 fps on LG C9 oled via external hdd. Only the Dolby Vision version runs at choppy framerate. I think mp4muxer is the culprit.

[daddy]

no, i don't think the culprit is mp4muxer because the file it produce looks correct.

I think it's just the SoC that can't handle the video bandwith it requires to make the dv picture at 60fps.
