Dolby Vision now possible through MP4 Mux.

I asked that because in the past I read people with problems in the shield and .pgs

Very bad news

In firestick pgs subtitles are fully supported in HDR files, so I dont see why they should not be supported in DV files

[DaMacFunkin]

I think the confusion surrounding pgs subtitles comes from Plex. Just to confirm Plex struggles with pgs subs in all files, other players, Kodi, MrMC, shouldn’t have a problem.

[yusesope]

Just to clarify, during this testing phase when we talk about our test files (the final output of the various steps):

• m2ts -> Dual Track Dual Layer MEL (DTDL MEL)
• ts,mp4,mkv -> Single Track Dual Layer MEL (STDL MEL)

In case of variations it would be useful to specify it.
Are we all on the same page?
Good!

I also hope you are working with cuts and not full films... that would be crazy!
(OT: do native English speakers understand me when I say film instead of movie? Or rather, do they understand me ? By the way, I apologize for my English! I hadn't said it yet on this forum ... )

I did a quick test, used v4_method2 tool's FEL to MEL mode and latest tsMuxeR nightly with Transformers 4. The resulting file plays perfectly both on M9702 and LG C8's internal player. Previously the M9702 had problems playing single track, dual layer FEL movies just as the Sony X700 (they have the same SOC afaik).
Colours seem to be all good, but I'm gonna do some much more thorough testing at the weekend.

Of course mp4 files play correctly with the known limits for audio/subs.
In firestick only plex play m2ts/ts files created with the v0.0.4_BETA_method_2 correctly but no pgs subtitltles

Tested using v0.0.4_BETA_method_2
Sony x700 the m2ts plays flawlessly
Firestick bad news, in kodi/exoplayer m2ts does not play (the infamous "playback failed") and ts play only as HDR.

Exactly the same for me on Nvidia Shield with modded Exoplayer.

I read a lot of good news.
At this stage I'm interested in the mp4 format (simply because we have Dolby's mp4muxer and because Dolby itself got its hands on the ExoP code for this container).
Ergo, if ExoP correctly plays the edited MEL mp4 files and if the content of these files (transposed into m2ts DTDL) is played on the Sony X700/M9702 (devices that have only one task and cannot be modded...at least not by me) then the files we're testing aren't completely weird.
Comparison photos between FEL and MEL will definitively clarify the latter aspect (tolerating the possible differences between MEL and FEL).


TS plays correctly by Plex and not by ExoP ... well, then use Plex !
I do not see the problem (also because for subtitles there is the immortal srt format).

But you are insatiable, hungry beasts chasing their prey in the dark and attacking in the light of Dolby Vision's nits!
So, I say to you: unleash the **Scam Web Site** !!!
Instead of creating a m2ts MEL DTDL (by adding first BL.hevc and then EL_RPU.hevc in TsMuxeR), generate an ISO and feed it to MakeMKV.
Test the MKV output file on FireStick 4K (et similia) with my ExoP.


BONUS:
The ideal would be to implement all this in ExoP. That way, FS 4K owners could play their MKV FELs (Yep, FELs) on the fly while my code takes care of converting RPU units in real time.
I do not promise anything because I do not know if I am capable of that and the time to write lines of code is short, usually Saturday morning with a nice cappuccino and a delicious slice of homemade pastiera nearby (of which I am proud ... you know what, I leave you the recipe! You should definitely try! )

You can try if they supported in DV

With Makemkv do DV MEL and see if .pgs subtilles work with firestick/exoplayer

@yusesope I hate so much .srt subtitles

And Makemkv can't be update to this new method and everyone happy? assuming it is 1:1 of UHD and the method work
I just ask, I don't know

[Mr_Orange]

OT: do native English speakers understand me when I say film instead of movie?

Perfectly, since the word is 'film' not 'movie' for a native English speaker .

I don't know why I was convinced otherwise !
Thanks for enlightening me!
And above all, thanks for having glossed over the rest of what I write !
I bet my posts make people's eyes bleed (especially native English speakers)!
I apologize again...

[Mr_Orange]

I follow the information in this (and other threads) but I have neither the time nor the skill to undertake what is required so I'm happy to wait for native support to arrive in Plex for my Shield TV Pro.

@ragico
if it's not too much trouble for you, could you please upload two small samples so I can do some comparison. I need one untouched dual-layer FEL sample and one dual-layer converted MEL sample that plays on the x700.
I'm not sure of which tool I need to extract layers of a single layer file(bl+el+rpu).

thank you

I prepared the 2 files as per your request. One is untouched FEL and the other is MEL converted using Yusesope latest tool and instructions. Both files are in m2ts made with tsmuxer "w64-nightly-2020-09-20--02-24-10" and originate from the UHD disc "US". Both files play perfectly in sony x700.

Many thank's . I'll do some comparisons tonight.


EDIT:

how come the MEL file is now larger than the FEL file ?

[yusesope]

It is a wise choice! The important thing is to stay informed!

Thanks for what you do! And thanks also to @ragico...

how come the MEL file is now larger than the FEL file ?

This is not the only reason but it can help you understand.
Let's pretend we have two RPUs, a FEL and a MEL.

FEL -> B7 AB 01 44 FC 00 00 78 FF FF
MEL -> F0 00 00 00 00 02 01 22 69

Each alphanumeric pair represents one byte.
Which one takes up the most space?
The first! quite right? It's bigger than a byte!
No. the second!

In fact, there are "illegal" sequences of bytes that cannot be presented to a Decoder (000000, 000001, 000002) and these must be modified by adding a byte equal to 3 (03). Therefore:

FEL -> B7 AB 01 44 FC 00 00 78 FF FF
MEL -> F0 00 00 03 00 00 03 02 01 22 69

Who takes up the most space now?

If you think about it, a MEL RPU should be less informative and therefore it is more likely that there are more sequences composed of 00 and therefore a larger addition of 03 bytes is required.

Now repeat the whole process for hundreds of thousands of times remembering that every zero 03 increases the file size by one byte.

[RESET_9999]

so here are some comparisons. Pitch black room without any light, OLED TV, Camera settings locked, Tripod, and Bluetooth triggering.

Dual-layer FEL untouched VS Dual-layer MEL converted
https://screenshotcomparison.com/comparison/6565

the untouched FEL is brighter & has more punch, no doubt. But I think this is normal because I'm seeing the same kind(if not more) of difference when I compare the Spears and Munsil FEL & MEL

Spears and Munsil dual-layer FEL untouched VS Spears and Munsil dual-layer MEL untouched
https://screenshotcomparison.com/comparison/6564

Dual-layer MEL untouched VS Single-layer MEL (el+RPU) untouched
https://screenshotcomparison.com/comparison/6566

also from the bluray discs I inspected, FEL DV hevc stream is the actual movie with a white/grey tint on it while MEL DV is just a static white/grey image.
We still can see the video in the MEL conversion so that could be the reason why it doesn't play on the x700. I can add some random MEL track to any HDR10 hevc stream and it will still play in DV (single or dual layer). with some flickering but it triggers DV.


real FEL / real MEL / MEL conversion

[shawnc22]

the untouched FEL is brighter & has more punch, no doubt. But I think this is normal because I'm seeing the same kind(if not more) of difference when I compare the Spears and Munsil FEL & MEL

I also believe that this is probably the expected behavior. When FEL is processed correctly, it's produces a 12bit picture whereas MEL is only capable of 10bit. Even though we don't have 12bit displays, a 12bit stream downsampled to 10bit will still look different than a native 10bit(MEL) stream. A picture and picture comparison of the original FEL vs converted MEL may not then a be a good way of determining whether the method is working. One thing you can potentially try is since the S&M disc contains a demo that's provided in both FEL and MEl, convert the FEL to MEL and then compare it to the provided untouched MEL.

@yusesope
Hello, first of all thank you for your script and your involvement.
So I followed your procedure with the software and script made available.
I tackled MIDWAY Bluray -UHD fr.
For information I have a Panasonic HZ1500 Tv (I test the Dv player on the internal player).
I get an mp4 (without audio track because it is dts-hd), in 8 Dv profile which is read without problem by the TV.
Your procedure works perfectly.

On the other hand when I use TsMuxeR (version given in your procedure w64-nightly-2020-09-20--02-24-10) to integrate the audio tracks and pgs, TsMuxeR changes me the Dv 8 profile into Dv 7 profile, which him does not pass on my Tv, and therefore the video is read in HDR PQ.
