Dolby Vision now possible through MP4 Mux.

[Mithrandir]

thanks for the reply. can you please let me know what version of jellyfin you did this in? is FF/REW working for you with m2ts files in jellyfin? I had to move to Emby because FF/REW was not working for me with m2ts files in jellyfin and I can not use plex because it transcodes when SRT is enabled.

Latest Jellyfin Version: 10.8.10.

I didn't see you are using m2ts files.
I'm using MKV and MP4 files and FF/REW works completely fine.

I used ts few times but can't remember if FF/REW worked.
I never used m2ts.

Isn't m2ts designed to work only in disc players?

P8 with EL is not standard and there's no need to use it since your TV support dual track dual layer Profile 7 FEL. See my reply to @valington

Yes, I know that my TV 2019 supports 7 FEL, but not since 2020, and I need a universal option for tv 2019 and newer, up to this point I have used P8 BL+RPU, but I saw this non-standard option and it confused me. I am also aware that dvi.08.06 BL+EL+RU is not a DV standard, but still the question was, why does TV reproduce this option correctly, does it ignore el or somehow reproduces it as in cases with a two-layer 7 profile? And how did manage to get such an option dvh.08.06 BL+EL+RU?

Surprised that HEV1 works on the B9 since it doesn't work on the C8.
The only universal solution that works EVERYWHERE is the TS/M2TS container in P8.

I don't know but you can try to use this P7 file and remux it to P8 without removing the EL and see if FEL is used:
https://drive.google.com/file/d/1J5QnjW ... share_link
you can force P8 with the mp4muxer:

Code: Select all

"%mp4muxer_path%" --dv-profile 8 --input-file ST-DL.hevc --output-file "output.mp4"

[TheEqualizer]

I tested your video, extracted hevc from the TS container and got mp4, although the command that you gave lacks the -compatible-id parameter, it gave an error without it, I made all three options with -compatible-id 1 (2) (4) for full confidence. All three videos are strobed by the built-in player LG B9. I don't know why this doesn't happen on a particular movie...

The only universal solution that works EVERYWHERE is the TS/M2TS container in P8.

Which specific version of tsMuxer do you recommend using?

[begentle]

So much info in the thread, so what i gather is by converting a DV mkv with FEL to profile 8.1 we loose FEL?

So it’s the same a playing a DV MKV on a zidoo or dune? FEL is discarded and only the rpu is used?

yes FEL is discarded but know that not every FEL movie can be converted to P8 (or played on non-fel devices) because some of them are expanding the picture brightness when BL and FEL are decoded by the player.
So the DV metadata in the RPU is meant to be played with the FEL brightness ONLY. Playing these FEL movies on a non-fel device will result in an image darker than the intended look.

Here's a list of FEL movies that expand brightness (still looking into my library to find more):
https://docs.google.com/spreadsheets/d/ ... sp=sharing

This is really interesting - and I'm extremely grateful for all the info you've gathered here.

What's the best way for me to check my own collection to see which FEL discs expand the picture brightness? What data should I be looking for?

[RESET_9999]

although the command that you gave lacks the -compatible-id parameter, it gave an error without it,

Because I use the old mp4muxer that works on all the LG TVs and this parameter was implemented in the later versions of the mp4muxer.

All three videos are strobed by the built-in player LG B9

the homemade FEL test file can indeed be buggy on some players.

Which specific version of tsMuxer do you recommend using?

The latest one should be fine.

The only downside of using TS on LG TVs is that you have to use external SRT subs. Some comments here recently said that ext srt doesn't work but on my end (PLEX C2), it still works.

[RESET_9999]

What's the best way for me to check my own collection to see which FEL discs expand the picture brightness? What data should I be looking for?

Usually, the HDR10 base layer mastering display lum metadata will say 1000nits, and the RPU metadata will say 4000nits but the two only ways to really know is by plotting DV/HDR10 or by exporting some screenshots with the dovi baker.

E.G. Deep Impact:

You can do all of this with the script in my signature.

I redid it using the same old version that is in your tools folder, the result was the same, a strobe light, this suggests that the TV cannot correctly reproduce dvhe.08.06, BL+EL+RPU? If could, would I see a normal color scheme?

I think it works with Plex/Jellyfin, but it doesn't work with built-in WebOS player (if you trigger the file via DLNA).

Also, internal webOS doesn't support PGS subtitles (which are usually present in Bluray remuxes).
Is there an option in your script to convert PGS to SRT?

That's really helpful - thanks!

I guess the next step for me is to learn how to get DoviBaker to combine the BL and FEL (any tips would be welcome!) so I can do some test re-encodes...

The flashes are the mapping in the RPU. When fel is used, you're supposed to see a 2nd video in the background like this:

[RESET_9999]

Is there an option in your script to convert PGS to SRT?

No, because it requires manual verification to be accurate. I use subtitle edit.
https://github.com/SubtitleEdit/subtitleedit/releases

or most of the time , someone already converted them to srt: https://subscene.com

[TheEqualizer]

I checked again, dvhe.08.06, BL+EL+RPU is not supported from mp4, only TS dvhe.07.06, BL+EL+RPU it is supported, I see both images.

In general, as I understand it, what was tricked out in that mkv (dvhe.08.06, BL+EL+RPU) is not correct and it is not necessary to do so?

And the last question, did you have the opportunity to check TS (dvhe.07.06, BL+EL+RPU) on LG OLED TV 2016-2017-2018-2019-2020-2021-2022-2023 or else on some other, since you wrote that this is the only universal option.

Well, it could be right as long as FEL doesn't expand the brightness. Looks like the dynamic metadata is used.
But better just convert P7 to true P8(no el and remove mapping) for playback on non-fel devices but once again, as long as FEL doesn't expand the brightness

2017-2019...
P7 ST-DL: TS or MP4, some files give black screen.
P7 DT-DL: Ts doesn't work but mp4 works. (some fel file may stutter)
P8/P5: TS and MP4 are fine

2020+ ...
P7 ST-DL: HDR10
P7 DT-DL: HDR10
P8/P5: TS and MP4 are fine

[Mithrandir]

@RESET_9999 I've used MP4 workflow with DV P5 mkv (workflow 7 if i recall correctly).

After converting I'm getting random audio dropouts during playback on LG CX (internal player).
I'm using latest scripts (1.8.3).
Did you had similar issues?

I've used your scripts in the past (maybe a year ago) and didn't encounter similar issues.
