Dolby Vision now possible through MP4 Mux.

[pitrako]

At the end I muxed with tsmuxer profile 8 fix into .ts instead of mp4muxer and dolby vision worked on the native tv player (does not triggers dolby vision in exoplayer) but I get strong red colors on people's skin, too much.

EDIT: I tried again all the steps from yusesope but instead I used -mode 2 instead of default mode on his tool and this time It triggered dolby vision on exoplayer. All this on 1917 (FEL title).

[yusesope]

This has changed?

I hope so

I’ll try and test over the weekend

Let us know! If you are using Windows, please read the central part of THIS post!

I presume that this isn’t something that could be done ‘on the fly’ at some point? We would need to change the makemkv MKVs to these MP4s each time? I.e. wouldn’t be able to just play the FEL mkv using exoplayer.

I wrote everything in C++, you could run my code on a toaster! The problem is the implementation: a good programmer would take a few hours ... I need my time. The idea of ​​integrating everything into ExoP has been in my head for a while but I still don't know if I have the skills to do it! I'll try it in my free time when I feel like it!
However don't worry: mp4muxer should only be used in these test days. As soon as @jcdr428 updates TsMuxeR (in order to get profile 7 files), you can start using it as it is much faster than the first one and allows you to create files with TrueHD/ATMOS audio included!

I tried "A quiet place", It's a FEL title, in exoplayer through kodi and doesn't play, It stays at 00:00. And I think I followed all the steps...

Did you also follow the first important step?

......playing any FEL UHD-BD backup on Android devices equipped with a Dolby Vision decoder and capable of playing THIS file (+ my ExoPlayer) or THIS file....

Is your device capable of playing these files (the first only through ExoP)?
If the answer is no, unfortunately there is nothing I can do! However (and this also applies to @hepe9), take the positive aspect: if all goes well with a 40-60€ FireStick 4K you can play UHD-BD backups as MEL without giving up ultra-high resolution audio (PCM in most cases). I think this is good news! No?

EDIT: I tried again all the steps from yusesope but instead I used -mode 2 instead of default mode on his tool and this time It triggered dolby vision on exoplayer. All this on 1917 (FEL title).

This is interesting ... But unfortunately I don't think it is the correct way to proceed!

In next days I will compare it with the original disc played on sony x700 feeding a Panasonic GZ2000 oled.

I'm curious! You could also call @RESET_9999 and take some pictures together !

I will get it corrected in tsMuxer.

Thank you for your time!

So for playback on LG (C8 in my case), some FEL movies like 1917 and Gemini Man would always give heavily stutter (both from USB HDD and Network)
Would converting them from FEL -> MEL fix this issue?

... and this version of mp4muxer. Before testing an entire film I advise you to work with 120 second cuts.

Also would you happen to have a diff file for mp4muxer so I can build on Linux ?

I don't have it but there is an x64 version in the archive that I used on Ubuntu.

Absolutely yes, very good news

I can't wait for comparatives

Yeah you're right, the mp4muxer_64bits binary also seems to work on Fedora 33 (beta).
For the record, I've demuxed the bluray iso file of Gemini Man:

Code: Select all

ffmpeg -i bluray:///home/mastag/Video\'s/GeminiManISO -map 0:0 -c copy BL.hevc
ffmpeg -i bluray:///home/mastag/Video\'s/GeminiManISO -map 0:1 -c copy EL.hevc

Then I used tsMuxerGui to demux the truehd track and downconvert it to (core) ac3.

Now I'm muxing it with your tool with conversion to MEL:

Code: Select all

python src/app.py -mux -fel_to_mel -bl BL.hevc -el EL.hevc -of BL_EL_RPU.hevc

it takes a while.. 58% now..

When it's done I'll use your mp4muxer_64bits binary to mux the BL_EL_RPU.hevc and the ac3 audio which I got from txMuxer into a single mp4 file.

I'll let you know!
Thanks for everything bro!

EDIT: Done!

Code: Select all

mp4muxer -i BL_EL_RPU.hevc --dv-profile 7 -i 00222.track_4352.ac3 --media-lang eng -o Gemini_Man_2019.mp4

[ragico]

I did my second complete movie: Us
This is really a challenge for a dolby vision chain. Until today only the original disc, played in the sony x700, was really correct to my eyes. I did not like the mkv version played trough the shield because of something wrong here and there with the colours.
Then I have watched the most critical scenes of this mp4 via firestick comparing it to that of the sony ( both devices almost syncronized) and could not detect any difference between the 2. Then I compared Despicable me 3 in the same way with same results. I have not a camera to take screenshot foto just my phone. I wait for comments from others as @RESET_999.
Maestro Yusesope. BRAVO.

[RESET_9999]

I'm curious! You could also call @RESET_9999 and take some pictures together !

I have not a camera to take screenshot foto just my phone. I wait for comments from others as @RESET_999.

Unfortunately, those converted MEL files dont play on my x700 so I can't properly compare them with the original. And the shield cannot output proper colors for ANY file that contains an EL and i dont have any other device to test..

the native single layer MEL (el+RPU) movies play fines but not the converted one.

I hope other can do the comparative, because if work, it's the great deal

Yes, these converted Mel files dont play on my x700 too. So I plugged my firestick into the Pana to compare them with the discs played on the x700.

[hepe9]

@ragico one question, the Firestick works good with .pgs subtitles in the Exoplayer?

[Meister_Proper]

This latest innovation together with the previous idea of ​​combining the two layers (BL and EL_RPU) in a single track, should guarantee the possibility of playing any FEL UHD-BD backup on Android devices equipped with a Dolby Vision decoder and capable of playing THIS file (+ my ExoPlayer) or THIS file.

The GIJoe P7 MEL triggers DV on the Zidoo Z9X, but your FEL to MEL plays in HDR10 only.

Thanks for your valuable tests!
The fact that devices like the FireStick 4K have no problems playing this type of file encourages me but the issue of the Sony x700/Zidoo Z9X leaves me a bit of a bad taste.

This is a second attempt based on a slightly different idea from the previous one.
Does THIS FILE play on both FireStick 4K and Sony/Zidoo Z9X?
Thank you!

Clearly, the test is also extended to owners of different devices (obviously interested in the FEL -> MEL).
In your posts please also specify the device.

EDIT: Done!

But you didn't let us know if it works on LG or not .
A little tip: if you don't need to make cuts, you can extract video and audio with a single command

Code: Select all

ffmpeg.exe -i \path\to\file -map 0:0 -c copy \path\to\BL.hevc -map 0:1 -c copy \path\to\EL.hevc -map 0:XXX -bsf:a truehd_core -c:a copy \path\to\AUDIO.ac3

Clearly replace "XXX" with the correct TrueHD (with ac3 core) audio stream id

@RESET_9999 we need you, I hope now works in the x700

@yusesope you're amazing
