Dolby Vision now possible through MP4 Mux.

[shawnc22]

I have ripped the movie The Meg to .mp4 DV single layer using DVDFab and it shows up as DV in the Infuse GUI and plays as such just fine. The colors seem the same as when I play the disc in my Sony X800M2. I’m an ISF Certified Calibrator amongst many other industry things for 30+ years so would notice if color was amiss. What color issue is it that I’m supposed to be looking for exactly?

So UHD BR discs are mastered in the YCbCr colorspace, and original single layer profile 5 videos are supposed to be in the IPTPQc2 colorspace. Unless DVDFab is doing a colorspace conversion in the ripping process, the resulting file from the process is a profile 5 video but with the content still in YCbCr. The thinking is that when a device like the AppleTV starts playing a profile 5 video, it's expecting content in IPTPQc2 colorspace, but if the content in the file is actually still in YCbCr, it should result in some color issues, no? The differences can be subtle, though, so that's why you might not be noticing anything significant.

I can't seem to change Codec ID: dvhe to dvh1. I tried using flexhex but didn't get too far. Is there a python script I can run for this? The file source was a UHD Blu Ray profile 7 dual layer I made into a profile 5 single layer with BL+RPU excluding the EL. Is it okay I leave SMPTE ST 2086, HDR10 compatible for the HDR format?

The differences can be subtle, though, so that's why you might not be noticing anything significant.

OK I see where you’re going with it now. I have my system calibrated running it in LLDV through the AppleTV, so I compensated for any color differences if they were there.

I still have my doubts though. I’m sure the DV processing on the AppleTV can detect what color space the source is in. From what I recall reading in white papers about DV creation in end unit devices using their programmed SoCs, it showed and included YCbCr input and ICtCp which in the end stage was converted to YCBCr for HDMI output. Of course I’ll have to go back and refresh my memory and the details.

[mattmarsden]

This is the AM6 plus playing the FEL test mkv through the Kodi 19 special DV build. Unfortunately playback is choppy on all FEL files for me, I'm not sure how I can get them to play smoothly.

[mattmarsden]

I'm presuming the FEL layer is being software decoded - not sure if the AMlogic chipsets have dual hardware decoders?

[mattmarsden]

OK, dual track MP4 plays fine through the internal player with FEL so it must be a Kodi issue it not playing smoothly.

[NiCE77]

This is the AM6 plus playing the FEL test mkv through the Kodi 19 special DV build. Unfortunately playback is choppy on all FEL files for me, I'm not sure how I can get them to play smoothly.

Try with official final build, surprising but playing DV from mkv or try with Plex.
Amlogic has 2 hw decoders.

Have you been able to get Atmos, DTS:X, or other lossless audio to work with the AM6?

[mattmarsden]

I've tried with Kodi final build and it plays OK but a bit stuttery and often doesn't work after seeking. Plex doesn't seem to work at all with them for me. Interesting about the 2 hardware decoders - where did you see that?

[chros]

I just tried a FEL mkv (07.06 BL+EL+RPU) on Firestick 4k with final v19.0 Kodi and it triggers DV on the TV but the image is blank (black)
I guess that's expected.

[HarperVision]

Thanks for the comparisons; unfortunate to see that the EL is ignored again. It would be great to get the same FEL/colour accuracy comparisons on the Ugoos AM6 Plus and the Chromecast with Google TV if possible, now that there are some reports that they properly decode FEL.

Manix should be able to test the Chromecast as well. He doesn't own the Ugoos.

Damn it... only Total.Recall.1990.SL-P8-MEL.mkv file enable Dolby Vision with my Chromecast with Google TV, every other file plays in HDR10.
I tried to create a mkv file via MakeMKV from the .iso, but it does the same. So I can't test the FEL processing...

The other samples worked well and other DV FEL files also do it fine, but not these ones... anyone can contribute with a solution?

Thanks in any case

yeah, it's probably because of the splitting...
FFmpeg gives me some warning when I try to demux the splitted layers.

I have ripped the movie The Meg to .mp4 DV single layer using DVDFab and it shows up as DV in the Infuse GUI and plays as such just fine. The colors seem the same as when I play the disc in my Sony X800M2. I’m an ISF Certified Calibrator amongst many other industry things for 30+ years so would notice if color was amiss. What color issue is it that I’m supposed to be looking for exactly?

The only reason I’m not satisfied at this point is due to the lack of ATMOS audio.

So am I reading right that the new Chromecast Google TV is capable of playing all DV profiles with MEL and FEL and ATMOS?

Since you have the x800m2, why don't you just remux your bluray with tsmuxer and play them via USB ?
Even if profile 5 with HDR10 base layer ''could'' be looking right, you're missing the EL.

Thinking of going for an Oppo 203 for DV - does anyone know if the issue of the green garbled screen after playing a DV m2ts has been solved?

not fixed, it's a tsmuxer bug. But the oppo can play ISO without the bug, so just use that format.

Is there a step by step guide for how and what to remux with tsMuxer? I’ve tried doing a few and I’m not sure the end result is what was desired or needed.

I’m not sure I like the GUI/Menu trees and process of watching using the X800M2. Frankly it’s ugly and takes me back a few decades. There’s no cover art, etc. By the time I navigate all the way into it to get to the movie file, I could’ve inserted the disc and played a better version of the movie with full ATMOS.

It is by far the easiest and fastest method. Get the latest tsMuxer here: https://github.com/justdan96/tsMuxer/releases
then just drag and drop the largest m2ts file (or the corresponding playlist file) into tsmuxer, select the track you want to keep and start muxing.

There is no quality loss compared to the disc playback and you can keep full ATMOS and subs.

Thanks!

What is the fastest method?

So what exactly is muxing doing? If I rip my movie using DVDFab I can play it in that format already, so why mux it?

How do I know what track to keep after dragging and dropping the largest file (or playlist)? Which and why am I choosing it?

This is what I’m talking about. Every answer I see on these corresponding threads are always so short and abbreviated, assuming the reader just knows everything involved already. It seems nobody ever makes a post with step by step instructions with clear and concise answers as to why and what you’re doing. That’s how I learn anyway.

Either way, thanks a ton for helping me get there!

Thanks for your tests! @Manixx2020beyound @RESET_9999

According to Dune's FW changelog, the FEL layer is supported on FullBlurays only, and only MEL layer on MKV. It is right ? or does the FEL layer really not work on ISO and BD either?

I can play without problems FEL DV files with "Dolby VS10 Engine Always" enabled.

On the other hand, if the FEL layer is not really taken into account by the Dune, even if it reproduces it ..
my TV is an LG OLED, compatible with FEL, in principle? If I select "Dolby Vision Output Mode" in "tv-led", would the benefit of the FEL layer from Dune to LG OLED?

Thanks!!

@Manixx2020beyound finally got his hands on the new Dune player, time to do some comparisons

Unfortunately, the Dune does like the Shield and ignores the EL but there is no red push and the colors seem to be accurate. Even though it looks like the dune is ignoring the EL, there is still an improvement compared to the base layer. We have to compare it with a P8 rip.

Of course, this is an extreme case and it wouldn't be so different if the studios encoded the base layer properly in the first place but the improvement that the FEL brings here is phenomenal, imaging when we'll have true 12bit TV.

DVDFAB can't remux DV with Atmos and it's remuxing into a mp4 container which is a bit buggy on the x700/x800m2.
This is why you need to use tsMuxer which (just like DVDFAB) makes the file playable in DV (TS or M2TS container). tsMuxer also supports Atmos (or any lossless audio).

The tracks you keep are:
1- the 1st HEVC stream (HDR10 base layer)
2- the 2nd HEVC stream (DV layer)
3- any audio you want (you can add external audio)
4- any subtitles you want.(you can add external subs)
