Dolby Vision now possible through MP4 Mux.

[yusesope]

I reuploaded the MI Fallout samples to Mega: https://mega.nz/folder/zIUHyYgI#IdP6COvbAQ8vNVA0MSH6Jg

Thank you.

so there must be something happening between tsmuxwer and yusesope tool which i cannot root out.
Is anyone having similar issue lately or maybe it is a bug?

Have you tried to create an mp4 file after the FEL->MEL conversion?
If the official Dolby tool does not encounter any problems, it means that the raw HEVC stream that my tool returns is correct.
Give it a try and let us know!

3 films: The Shining, Doctor sleep and Jaws.
They are DV Mel and also HDR10+ compatible.
None of them plays in Firestick 4k.
Audio only with black screen.
Anyone can explain why?

same, we wanted to test the doctor sleep sample on the firestick but no go

My android TV has the exact same DV implementation as Firestick 4k. I've tested The Shining which I ripped using 1.15.2 and it works flawlessly. Haven't tested the other 2 titles.

HDR10+ should be backwards compatible.
I don't think that's the problem, but you can always create a file using BL only (without DV).

Code: Select all

ffmpeg -i BL.hevc -c copy output.mkv

If the screen stays black then the problem is HDR10+.
If you upload a sample, I can check it out.

Just wanted to give some feedback on the new mode 2 (profile 8.1). It works very well.
From a FEL MKV, converting to 8.1 and back to MKV works with Plex on the Firestick 4K.
The converted 8.1 file can also be used in TS on LG webOS Plex and internal player, both trigger Dolby Vision.

So from the MKVs created by MakeMKV, there is a lot of compatibility fixes possible.

Thanks for the feedback! I had imagined the 8.1 profile just for those devices like TVs that have problems with UHD-BD MEL\FEL.
I'm glad it works.




For now, however, I'm doing some tests to see if I'm able to "cook" custom mkv and mp4 files with Dolby Vision.

The idea is to accept a Single Track\Dual Track file (with DV metadata intact) mp4 or mkv or ts or raw HEVC as input, give the possibility to select the audio tracks and subtitles of interest, choose, as happens now, the output mode (FEL->FEL, FEL->MEL, MEL->MEL, UHD->profile 8.1) and return an mp4, mkv and maybe even ts as output (instead of the actual HEVC).
The idea it's quite demanding and I don't know if I'm capable of it .
Unfortunately there is so much to know and I only approached this world a few months ago (with some hours available on Saturdays) .

THIS however is the result of a first test .
It is a DV FEL Matroska file (version 4 with CRC and error detection at the first level).
The new Mediainfo correctly detects all the info but the definitive proof is to play it on the Shield (because FEL).
By the way, it's the intro of Terminator Dark Fate: it is normal that it is "glitchy" .
Am I on the right track?
Thank you.

Hello yusesope it's interesting.

The idea is to accept a Single Track\Dual Track file (with DV metadata intact) mp4 or mkv or ts or raw HEVC as input, give the possibility to select the audio tracks and subtitles of interest, choose, as happens now, the output mode (FEL->FEL, FEL->MEL, MEL->MEL, UHD->profile 8.1) and return an mp4, mkv and maybe even ts as output (instead of the actual HEVC).

This sounds quite ambitious.
Maybe a good starting point is to just accept a MKV (in addition to raw that exists already) and be able to output the raw converted HEVC file. That on its own would save a lot of time (demuxing MKV, demuxing BL/EL, converting/remuxing 8.1), and might be simpler to do.

Afterwards, the only step left would be to pass this file through MakeMKV, and it can be reused in the original MKV, simply replacing the video (I'm not sure if mkvtoolnix would keep the headers intact if the video changes to a raw file?).
That way you don't have to handle audio, subtitle, etc.

The new Mediainfo correctly detects all the info but the definitive proof is to play it on the Shield (because FEL).

Thank you.

For what it's worth, the file behaves the same as a FEL MKV on the Firestick.

my friend had some LLDV tonemapped to SDR capture samples for me today. Good news for the Firestick Tv owners, it looks like it does DV the right way even though I see a small difference on white in the comparison #1 compared to the x700.


x700 vs shield vs firestick vs Chromecast. (use number keys on your keyboard to switch between the image)

SKYFALL MEL DV.... 3 comparisons of each device:

x700 vs Firestick: https://screenshotcomparison.com/compar ... /picture:2

x700 vs Shield: https://screenshotcomparison.com/compar ... /picture:2

x700 vs Chromecast: https://screenshotcomparison.com/compar ... /picture:2

Firestick vs Shield: https://screenshotcomparison.com/compar ... /picture:2

Shield = worse of all, oversaturation and ugly red artifacts everywhere. -----> btw I didn't look for a movie with artifacts, I took the first MEL movie I found and it still had red artifacts.
Chromecast = oversaturation but no red artifacts.


Spears and Munsil, x700 Original MEL vs FEL to mel conversion: https://screenshotcomparison.com/comparison/7017


same method:
-all the players send LLDV.
-Vertex tone map DV to SDR using the same settings.
- The signal is captured using the same settings.

Thx again.
Is it possible to make captures with streamed p5 content samples? Like, let's say, Mandalorian.

Only hope with more attention to this issue nvidia will have to fix it one day.

@Yusesope
Your "test" file plays in both shield and ugoos am6+ and triggers DV.
In Firestick black screen.

Tried BL only from Doctor Sleep and in Firestick it triggers HDR10+, so it is not possible to compare this DV film between shield (known problems) and firestick.
We need a Mel conversion that triggers DV in firestick.

yes, I asked him about that. He's in the USA, so he can compare Vudu x700 as well.

Thank you.

you're welcome. Credit goes to @Manixx2020beyound for the vertex 2 captures.

I just watched Skyfall last night on the SHIELD and I concur with the red push everywhere. The SHIELD just doesn't want to play nice.

[lexyz]

I can remember this shield defect in Aquaman or Valerian
It should be, but could be hard to spot by naked eye

[SamuriHL]

It's one of those "once you see it it can't be unseen" kind of things.

Do people still have faith that Nvidia will get this figured out eventually? I really want to sell off my OPPO and combine my libraries....

Truly unknown. We're not sure exactly what the issue is that's causing it. It's very possible the SHIELD just doesn't support decoding the parts of the DV spec that UHD is using. In which case, nope, it'll never get fixed. It's designed to play streaming DV content which is encoded differently than UHD DV content. All we can do is keep reporting it to them until they tell us to go away.

Would comparing UHD DV to a streamed DV counter part help? I mean if the streamed DV counter part looks correct then I agree we have no chance of this getting fixed.

Or is it not that simple and comparing some streamed content to say the X700 not really help? That said, I’m struggling to think of a title we could even use too
