Dolby Vision now possible through MP4 Mux.

Thank you for the response. So using tsmuxer to mux my MI4.HEVC, MI4.AC3, and MI4.eng.forced.srt together into MI4.ts will result in PLEX playing the subtitles automatically?

it may work if you mux them to TS, I always leave .srt as external subs with Plex, that is what the .eng.forced switch is for. External is also the method for using .srt with Oppo.

The files that are created by this latest version have as VUI:
0,9,16,9,2 for the Base layer
0,9,16,9,2 for the Enhancement layer.
The correct profile should therefore be 7.
Now I don't remember well but it seems to me that TsMuxeR currently generates files with profile 6 (but, I repeat myself, I could be wrong). If my tool proves to work, in my opinion, we should try to mark the ts files with profile 7 (and not 6).

I think yusecope is suggesting that what tsmuxer is currently registering as profile 6 should go back to being registered as profile 7

Yep, Exactly!

Got it! I always assumed that dual PID were profile 7, and single PID were profile 4/6.
I will get it corrected in tsMuxer.

Just tried this and it works on the FireTV Stick 4K.

On archlinux, my steps (starting from a mode1 muxed BL_EL_RPU.hevc file):
Mux to mkv, split to make smaller.
Demux to hevc.
python app.py -lbf 50 -demux -fel_to_mel -if video.hevc
python app.py -lbf 50 -mux -bl BL.hevc -el EL_RPU.hevc
mp4muxer_64bits -i BL_EL_RPU.hevc --dv-profile 7 -o test.mp4

And it plays in Dolby Vision with ExoPlayer.
PS: there should probably be an indication or something to stop instead of just "Wait...", the default -lbf value just hanged because the file sample is small.

A Firestick playing DV profile 7?

In this thread I read to many people saying the Firestick can't play DV profile 7

I'm confused right now

A device's inability to previously play profile 7 files probably has more to do with the fact that the BL and EL+RPU layers were in separate tracks and not the actual profile label itself.

Knowing this, I tried a Mel with Makemkv and Exoplayer with the Sony Xf90 and it all have red tones, the hardware of this TV is a crap if a simple Firestick can do it

[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.
