Hi guys, I've got Alida working with Dolby Vision through USB on a philips 804. Plex doesn't recognize dolby vision but only hdr 10 +.
I've simply used mp4muxer muxing BL + EL + audio. The process is slow, even with a nice PC, and even if says "0kb" in reality is working.
Anyway I don't see much difference from an HDR 10 +, is that normal? It looks like this process it's just a fake thing...
that's because, with current displays, hdr10+ is the equivalent to dolby vision. they both offer per-frame specular enhancement over regular hdr10. mp4muxer is definitely not fake as it keeps the seperate layers intact, just like uhd discs; it literally just changes the container. single layer mp4s from DVDFab, however, remain quite questionable at best..
questionable in what regard?

I’ve heard the questions also and don’t agree, I watched Terminator dark fate in HDR10 on my 65” LG C9 and then watched it again in single layer DV on my 55” C7, I preferred the picture on the C7, whatever it does it does something better.

I think Grencola mean DVDfabs single layer conversion is questionable, which I agree.
Some conversion work flawless on my C7 and LG UHD BLuray(USB), however films like Transformers 1-4 just mess up, red & green flashes and if I use the UHD player it looks like i've dropped my screen with vertical coloured lines tearing up the screen.

I have the same problem with bumblebee on the LG which is essentially a transformers film but it plays fine on the Shield Pto 2019.

The USB ports on the C9 are only USB2.0, maybe the combination of your USB chipset and the v2 port isn’t quite fast enough for some high bit rate titles.

Usb 2.0 has a speed of 480 Mbps which is way higher than these films’ bitrate (less than 100 Mbps), so there shouldn’t be any problem right?

Btw, the hdr10 version of the same movie still runs fine, so I doubt this is a bit rate problem but the remuxed dolby version itself

in theory yes, but in practice no, that’s why I mentioned the chipset.
Maybe your right, all I know is I have no probs with jitters or stutters with single layer DV playback on my C9, but I do have a shield serving it via wired LAN.

Is there a way to play these dolby vision fileS from pc?

I did more than 60 Dolby Vision dual layer files.
Except Gemini Man (60fps=>stutter) and Universal Soldier (peak > 100 Mbps), all of them play fine on my C7.

What did you use to play them with? I try usb and some stutter (hdr10 always play fine but some dolby vision files do not). I want to try plex but the speed is limited by the internet.

Does anyone manage to play gemini man dolby vision smoothly at 60fps via usb? Mine seems to play at lower framerate. I used grencola tool.

It sounds like the LG 2017/2018/2019 OLED tvs do not seem to support HFR as Billy Lynn's Long Halftime Walk does not playback well over the LG tvs built in media player or through the Plex app. Billy Lynn's Long Halftime Walk(HFR 60fps) plays perfectly on the Nvidia Shield via gigabit Ethernet. It could also be the crappy wifi being too slow.
LG annoyingly got rid of the usb 3 port on the 2018 models and above. Since you have the LG C7 try an SSD(or a super fast USB 3 flash drive) hooked into the tv with a USB 3.0 to SSD adapter(I use the Sabrent EC-SSHD) and copy the the DL DV Gemini Man to that SSD and see if it plays on the internal media player. If it still lags like crazy the SoC is the culprit but if it plays perfectly then the wifi is causing all of the issues for us all. I remember reading somewhere that the 2017 LG OLED did not support HFR but the 2018/2019 LG models doesn't seem to either via the internal apps.
