Dolby Vision now possible through MP4 Mux.

Those files, provided by @quietvoid are mkv.
So I remuxed them in Ts muxer.
In Plex both mkv and ts remuxed files do not work. No rpu.
So, to answer my question, P8 ts files in Plex are fake DV.

ok so
fake p5 TS = no go
p8 ts =no go
p8 mkv = no go as well I guess?

one last thing to try,
fake p5 mkv: https://drive.google.com/file/d/1H_edhc ... sp=sharing

The file cant be played in Plex.

Guess fake P5 mp4 will be the only way.

Sorry I’m a little confused, what do you mean by “dynamic metadata”?

The original post asked about HDR playback.

What you're talking about is the Windows app, which only outputs SDR.
That does dynamic tone mapping but no HDR output.

My bad. Sorry.

Wait, there is something wrong with the file. Windows TV and Movie can't play it either.
I got an error message when demux it through ffmpeg.
Could you please re-upload that and give it a re-test?
Just for preciseness.

I don't know, it plays fine in MPC and MPV.
I tried with another fake p5 mkv and indeed, the Movies and TV app can't play it.

FYI, @ragico tested, LPCM, DTSHD, and TrueHD in a dvh1 MP4 container and the ATV fails the play the audio.
So the best we can get is EAC3 1536kbps.

Is it possible to decode and play Dolby Vision movies on a PC monitor?

For example, the Alienware AW3423DW (34" Ultrawide, QD-OLED, "HDR") doesn't support Dolby Vision but can software decode the Dolby Vision and display it instead of having the monitor decode it?

Not completely supported as if it was played in real Dolby Vision.
At best you can playback profile 5 in HDR10, with no extra dynamic tone mapping using the metadata.

mpv supports partial processing of profile 7/8 as well, but that might be inaccurate in comparison.
As the processing isn't complete (FEL, for example).

I use a dv tv as monitor & widows app this is the playback I get from windows app
This is probably as close to dv on a pc with mp4, pc is in hdr mode when dv kicks in.

you forgot to mention that you have to use the Vertex to trick windows into thinking you have a DV monitor.

actually, if you turn HDR on in the windows display settings, you get HDR10 output with the RPU being used for the Windows app. Works with MP4 only.

Monitor need to be seen as this

Hi guys how can i do dolby vision file for my LG OLED 2018 from mkv 8 profile hybrid dolby vision ?

[sw5163]

script is almost ready:

Thank you all for your guys' efforts! Excellent work!

I don't know, it plays fine in MPC and MPV.
I tried with another fake p5 mkv and indeed, the Movies and TV app can't play it.

Maybe mkvtoolnix did something wrong when remux fake p5 mkv?
I'm not familiar with mkvtoolnix.

FYI, @ragico tested, LPCM, DTSHD, and TrueHD in a dvh1 MP4 container and the ATV fails the play the audio.

That is strange, Apple says it can play them.

The attachment 无标题.png is no longer available

TrueHD and DTS shouldn't work.
LPCM(7.1), flac(7.1), alac(6.1) all work fine on my iPad. But it would be impossible to tell if they are true loseless through the built-in speaker, lol.

I have some samples produced through my usually workflow. These could probably be the highest standards video on iOS devices for now. Feel free to test them:
https://drive.google.com/drive/folders/ ... sp=sharing

Those files are from Dolby demo disc "Core Universe". They are produced with the following command:
1. FLAC_7.1 (ffmpeg only encodes it in mp4)
ffmpeg -i 00003.m2ts -map 0:2 -c flac -strict -2 flac.mp4
2. ALAC_6.1 (ffmpeg only encodes 6.1)
ffmpeg -i 00003.m2ts -map 0:2 -c alac alac.mp4
3. PCM_7.1 (ffmpeg only encodes it in mov)
ffmpeg -i 00003.m2ts -map 0:2 -c pcm_s32le pcm.mov

And then muxed with BL_RPU.hevc by mp4box
mp4box -add BL_RPU.hevc -add audio.mp4 -new out.mp4

ALAC_6.1 sound channel is like this:

Also I would like to ask those pcm encoders in ffmpeg, cause there are so many of them.
pcm_(signed/unsigned/float)(16/32/64)bit(little-endian/big-endian), how can I know which is best to use?
I normally just use -c:a flac, it also saves some bandwidth.

actually, if you turn HDR on in the windows display settings, you get HDR10 output with the RPU being used for the Windows app. Works with MP4 only.

"with the RPU being used", like software decoding DV and lldv? or HDR10+? or just plain HDR10?
Samsung refuses to support DV.

[sw5163]

Do you have a file with a lot of cmv40 data?
According to saindriches, cmv4 seems to have a problem on Apple platform. I want to give it a test but I don't know what file is FEL with cmv40.
屏幕截图 2022-07-16 120548.png

you can check out the movie Hitman's Wife's Bodyguard. And I think you can remove cmv4.x with the dovi_tool

Update: This particular file seems fine to my eyes on SDR iPad. Hopefully apple can handle cmv4.x properly.

RPU effects are displayed in the Windows apps.

Has to be a Microsoft store app, not Win32 app and you need the Dolby Vision Extensions app from the store installed to make it work in store apps. Works with Microsoft Movies & TV app and new Media Player store app. Worked in the old Plex store app too but it's broken with collections introduction so not worth it IMO there for Plex. Has to be MP4 as stated.

It's how I verify any RPU misalignments myself when making the DV files on a Win10/11 computer for a while now.

Used to be able to watch too if you didn't care about pq inaccuracies but there's a bug lately on my end with Win 11 at least across reinstalls, DV file will cause video orientation to constantly switch upside down back again upside down again etc.

Playback/player probably tripping up parsing the Metadata, it's only on DV files it happens. Or they did something intentional to make you need more than we had so you go buy a licenced DV PC.

I just use my computer just to verify anyway like I said as my monitor has no local dimming so after 30 mins in HDR my eyes are bleeding anyway, oh well.

it works just like LLDV but in HDR10 PQ with brightness ajdustments ...
