Apple TV 4K only supports Profile 5. Apparently, the all-new Shield TV supports Profile 4 and 5. And with Profile 4, you get both: single track dual layer and single track single layer and all with lossless audio and ATMOS/DTS-X.
To clarify the profiles:
Profile 4 is SDR BL with DV IPT EL -therefore backward compatible with SDR, not HDR10.
Profile 5 is DV IPT colorspace BL, not backward compatible with SDR or HDR10, i.e. will not give correct colors on a non-DV TV.
Profile 7 is dual track HDR10 BL with DV IPT colorspace EL, backward compatible with HDR10.
Profile 8 is SDR or HDR BL with DV metadata, backward compatible with SDR or HDR.

Levels are only about bitrate and HEVC profile.
Just gave the 1917 movie a shot.

First using yusesope's v0.0.3 rev 1 tool:

Code: Select all

python src/bl_el_rpu_builder_v0.0.3_rev_1.py -bl ./BL.hevc -el ./EL.hevc -of 1917.hevc

BL_ANALYSIS: 100.0%  EL_ANALYSIS: 100.0%  BL_EL_RPU WRITING: 100.0%  (BL AUDs: 171176  EL AUDs: 171176)

ELAPSED TIME: 09m 08s
Press a button to exit
And afterwards I remuxed the 1917.hevc along with the TrueHD+ac3 core track from the bluray disc into a .ts file with the latest TsMuxer (built from source).

For the record, I didn't use mp4muxer in the process...

Here's the output file:

As you can see it reports: 04.06.

Shouldn't it report profile 05 instead?
Because your PR has been merged: https://github.com/justdan96/tsMuxer/pull/264 and I built the latest rev, which should include your fix.
Well now both 1917 and Gemini Man will stutter every one or two seconds..

This is on my LG C8 btw.

So either the change from yusecope's 0.0.3 to 0.0.3 rev1 caused this. (Was using mode 1 for both versions)

Or the updated tsmuxer could be the cause.
Since the previous revision was showing profile 8..

Either one of two is upsetting my TV.

I am therefore trying to modify at bit level the .ts files produced by FFmpeg.
I did some experiments using THIS file and HERE you can find the results.
If your device plays the original file, test the files I edited.
If there is a positive response (I have my doubts but there is no harm in trying!), I will explain what and how I did it.
could you explain what you did? I'm really interested in figuring out why some movies don't work on the Shield.

As you can see it reports: 04.06.

Shouldn't it report profile 05 instead?
Because your PR has been merged: https://github.com/justdan96/tsMuxer/pull/264 and I built the latest rev, which should include your fix.
You have to edit the the youscope tool

open up the .bat file in notepad and add -mode 2 to the end of the single line of text in there and save it.

python-3.7.6.amd64\python src\bl_el_rpu_builder_v0.0.3.py -mode 2

If you do that you will have a dolby vision 05.06 file

So your have hacked the Blu-ray dual tracks to move the second track to an EL layer in the first track. The resulting single track is BL+EL (which should be profile 4) with HDR10 (which should be profile 8 ), but is definitely not profile 5 (which is DV IPT without EL). You should ask Dolby to create a new profile :)

Edit: I don't really know how I should classify the profiles for your hacked files, but I've pushed the following to tsMuxer:

Code: Select all

    // cf. "DolbyVisionProfilesLevels_v1_3_2_2019_09_16.pdf"
    int profile = 0;
    if (!isDVBL)  // dual HEVC track
        profile = 7;
    else if (m_hdr->isDVEL)
        profile = 4;
    else if (m_sps->colour_primaries == 2 && m_sps->transfer_characteristics == 2 &&
             m_sps->matrix_coeffs == 2)  // DV IPT color space
        profile = 5;
    else
        profile = 8;
Edit 2: according to https://forum.blu-ray.com/showpost.php? ... tcount=645 , a single track BL+EL with HDR10 is actually profile 6 ! However the latest DV document DolbyVisionProfilesLevels_v1_3_2_2019_09_16.pdf states "These profiles are not supported for new applications" (profiles 0, 1, 2, 3 and 6).

What is it about a demuxed mkv rip that this tool doesn't like? Do you think it might be possible in the future?
Also would be my question, since Dolby's mp4muxer works perfectly (well at least mp4muxer_64bit.exe works) with extracted bl, el tracks from mkv-files. Watched couple of DV movies on LG Oled that way.
Edit I found the 64bit version of mp4muxer and my TV still doesn't activate DV when I play the output file, only HDR.

I have Shield 2019, using nightly tsmuxer to demux Annihilation bluray remux MKV, and repackage the BL and EL with the AC3 layer using mp4muxer 64 bit. But the Shield playing via plex always shows HDR. Any ideas what I'm missing? Would really appreciate it.
Bumping this because my edit got buried - any ideas why mp4muxer isn't working for me?

I've now tried with Annihilation and Aquaman remuxes. Could it be because I'm starting with the remuxed MKV? But I know other people on this forum have said they were able to rip BL/EL from a remux MKV with no problems (as long as they were using mp4muxer and not yuseopoe tool).

Thanks everyone for your work on this project. I've read through pretty much everything and its been extremely helpful.

             m_sps->matrix_coeffs == 2)  // DV IPT color space
        profile = 5;
    else
        profile = 8;
For the record I didn't change/alter anything.

I just updated yusecope's tool from 0.0.3 to 0.0.3 rev1 and updated tsmuxer to the latest git revision.

No changes/patches.. I'm remuxing the EL/BL straight from the Blu-ray disc, convert them with yusecope's python tool and then use tsmuxer to create a .ts file from the output of it.
So I'm not using mp4muxer.

Now previously this used to work on my LG C8.

Now it doesn't work any longer and just skips.
So either the upgrade of yusecope's tool or tsmuxer caused it.

So I assumed the profile was wrong in the resulted .ts file, since perhaps it requires 5 instead of 4, but I'm not sure.

It can also be rev1 of yusecope's tool producing different conversion causing the stutters.

@yusesope and others, any means to check whether your Blu-rays changed to BL+EL+RPU HDR10 single tracks work on TV, STB and/or OTT if we assign correct profile 6 to these ?

Edit: so profile 8 will get deprecated as well, it looks like Dolby are pushing for proprietary DV streams that cannot be read by non-DV TVs or STBs, to force people to buy Dolby equipment.

For the record I didn't change/alter anything.

I just updated yusecope's tool from 0.0.3 to 0.0.3 rev1 and updated tsmuxer to the latest git revision.

No changes/patches.. I'm remuxing the EL/BL straight from the Blu-ray disc, convert them with yusecope's python tool and then use tsmuxer to create a .ts file from the output of it.
So I'm not using mp4muxer.

Now previously this used to work on my LG C8.

Now it doesn't work any longer and just skips.
So either the upgrade of yusecope's tool or tsmuxer caused it.

So I assumed the profile was wrong in the resulted .ts file, since perhaps it requires 5 instead of 4, but I'm not sure.

It can also be rev1 of yusecope's tool producing different conversion causing the stutters.
As far as I know, rev1 of yusecope's tool merely added the AUD count debugging messages over the base version and didn't change how the resulting the HEVC file is constructed. If you're not using -mode 2 of the tool, the resulting file should be profile 4 (or 6 i guess according to the blu-ray forums), but definitely not 5 or 8 since the EL layer is not supported in these profiles.

Are you saying you had gotten TS remuxes to work on your C8's internal player with atmos audio? I was under the impression that LG's do not support lossless audio at all. At least on my B9, whenever I try to play any of my TS remuxes, I would always get the "This video does not support audio" message on the top right corner while the video is playing. As for the videos skipping, I've had some mixed results. Some of the files I've created with the older version of tsmuxer that produced prof 8 played back perfectly and some had the same skipping issues like you mentioned. Not a big issue for me anyways since they all playback perfectly on the Shield with the included Atmos track, but have you tried redoing a movie that you have known to work on your C8 with the new versions of yusecope's tool and updated tsmuxer to determine if it might be a title-related or tool-related issue?

@jcdr, I can recompile tsmuxer and give prof 6 a try. will report back with results

Thanks @shawnc22 . Or you can try this W64 build bb51a5f from my fork. Single tracks created from Blu-rays should be profile 6.

Code: Select all

    // cf. "http://www.dolby.com/us/en/technologies/dolby-vision/dolby-vision-profiles-levels.pdf"
    int profile;
    if (m_sps->bit_depth_luma_minus8 == 2)
    {
        if (!isDVBL)  // dual HEVC track
            profile = 7;
        else if (m_hdr->isDVEL && (V3_flags & HDR10))
            profile = 6;
        else if (m_hdr->isDVEL)
            profile = 4;
        else if (m_sps->colour_primaries == 2 && m_sps->transfer_characteristics == 2 &&
                 m_sps->matrix_coeffs == 2)  // DV IPT color space
            profile = 5;
        else
            profile = 8;
    }
    else  // 8-bit
    {
        if (m_sps->colour_primaries == 2 && m_sps->transfer_characteristics == 2 &&
            m_sps->matrix_coeffs == 2)  // DV IPT color space
            profile = 3;
        else
            profile = 2;
    }

Curious if this will play on the shield, I think not because the devs said profile 4 MEL, 5,8 and 9 are only supported.
We support profile 4 MEL (minimum enhancement layer). Also single layer profiles 5,8.9.

Anybody??

A way to remove HDR10+ without removing Dolby Vision?

Does that mean that profile 4 isn't the best choice for Shield because it doesn't have FEL? And we should use profile 5 if possible? Sorry if I'm misunderstanding, still trying to get this all figured out :D

Thank you guys for all the answers.. so I need to set mode 2 to get profile 5, got it :)
@shawnc22 No the internal player of my C8 does not support TrueHD/Atmos.
But I'm storing it for preservation reasons.

For playback I must select the AC3 core track or E-AC3 5.1.

What I meant to say is that.. before I was able to produce .ts files with -mode 1 hevc that would play fluent on my C8.
Even the 60fps Gemini Man was OK.

Just using the 0.0.3 tool to create a mode 1 hevc file from the BL/EL and then use TsMuxer to mux it into a transport stream.
See my success story: https://www.makemkv.com/forum/viewtopic ... 295#p86295

It would say:
Dolby Vision, Version 1.0, dvhe.08.09, BL+EL+RPU / SMPTE ST 2086, HDR10 compatible

The latest TsMuxer will say:
Dolby Vision, Version 1.0, dvhe.04.09, BL+EL+RPU / SMPTE ST 2086, HDR10 compatible

So it seems 04 will cause stutters every 1 or 2 seconds while 08 works fine?
Or it's caused by the difference between yusesope's 0.0.3 and 0.0.3_rev1 tool.

Just tested the following using yusecope's tool v0.0.3 and tsmuxer build edited to force all profiles to 6 (sorry @jcdr, saw your build too late, but resulting file should be same in this scenario):

Joker sample file that's been used extensively here before with no audio track:
- Plays on B9 internal player, triggers DV
- Plays on 2019 Shield, triggers DV

Full Joker movie remuxed with Atmos audio:
- Plays on B9 internal player (no stutter), triggers DV, and no audio support message (as expected)
- Plays on 2019 Shield, triggers DV and Atmos audio

Here is the resulting mediainfo from the full movie remux:

Interesting findings as my previous remux of the full joker movie that was prof 4 did stutter on my B9, so seemingly the stutter issue on the LG internal player is related to DV profiling. Also interesting that the Shield is able to play these since it's been mentioned in that past that profile 6 is not supported. As far as my eyes can tell, there is no discerning difference between the profile 6 vs 4 DV remuxes. Not sure what the best step is moving forward, since profile 6 has pretty much been deprecated? I had to go back to a 2016 version of the dolby profiles pdf to even find a mention of it.
