Hello, you can use TsMuxer

I'm testing this on my Zidoo z9X with the UHD of 1917. If I create the file as per instructions using Mp4muxer (by using Tsmuxer it only plays in HDR10) the resultant video file plays in DV. However if I then use tsmuxer to add that file and the audio stream from 1917 the output only plays in HDR10.

What am doing wrong?

Hi, if you want to do .TS to play DV you have to have a modified TS muxer. If you want, I can throw it at you. Otherwise, I did an ISO Blu-ray and then made an mkv in makeMKV and I played DV on Zidoo z9x.

I have the version of tsmuxer linked in the instructions. Is that not the correct one?

I have updated the POST we refer to during this testing phase.
Find all the instructions there.

This update "fixes" what was previously called "-mode 2".

The new lines of code should allow you to convert a UHD-BD (both MEL and FEL) in a file Single Track Single Layer profile 8.1 (STSL dvhe.08.0x, BL + RPU, HDR10 compatible).

All devices, especially TVs with proprietary OS, capable of playing profile 8 files (and which have so far encountered problems with DV) could benefit from this update.

Before starting, to find out if your device is able to correctly reproduce profile 8, use the test files that Dolby provides on THIS page

Happy testing!

I've tried the new -mode 2 with a FEL title (Atomic Blonde) and it plays on the Firestick 4K, while previous default (profile 7) just plays a black screen. So that's good news.
That's with an MKV (1.15.3) and ExoPlayer.

Unless it's automatically using -fel_to_mel when using, I didn't look.

The Dolby 8.1 sample also plays in DV as well using ExoPlayer, but not on the C8 internal player.
The tool created 8.1 plays well after mp4muxer --dv-profile 8 on the internal player but not Kodi or ExoPlayer (playback failed).

Posted: **Fri Oct 02, 2020 6:17 pm**

Trying the 8.1 and after creating hevc file using the following command.

Code: Select all

mp4muxer -i path\to\BL_EL_RPU.hevc --dv-profile 8 -o path\to\TEST_FILE.mp4

However this give error

Error: For Dolby vision profile 8, dv-bl-compatible-id should be set, value can be 1 or 2.

Do I use 1 or 2?

Managed to get 8.1 working on Zidoo z9X by using tsmuxer to combine with Atmos audio from UHD to create ISO. Then created MKV with MakeMKV. Only thing is audio is out of sync. Need to offset audio ahead by about half a second.

Playback gets juddery after about 5 minutes - unwatchable at that point

I tested them + 1 small conversion on oppo clone, all of them plays fine! Thank you!!!

Please I wanted to ask there no longer need to be used after MUX_AND_CONVERT_TO_PROFILE_81, use DEMUX step?
Thank you for the advice.

Tried it in a Sony Xf90 and the default player doesn't play the demos, the exoplayer played it but has the same problem with the profile 7, red tones everywhere

Thanks anyway

A correction is needed to the mp4muxer command line for profile 8.1. It should be one of the following (not sure which)

Code: Select all

mp4muxer -i path\to\BL_EL_RPU.hevc --dv-profile 8 --dv-bl-compatible-id 1 -o path\to\TEST_FILE.mp4


mp4muxer -i path\to\BL_EL_RPU.hevc --dv-profile 8 --dv-bl-compatible-id 2 -o path\to\TEST_FILE.mp4

Hi yusesope, I'm encountering an unusual problem using beta method 2. When I start demuxing the BL_EL_RPU file, it quits after a few seconds. And prompts me to press any key. However, task manager shows high RAM and Disk activity. So is it actually running? Any ideas on what could be causing it?

Update: There's something definitely wrong with the Demux.bat. I went through the thread and another person too has the same issue as mine. I checked with a shorter clip (6 mins), same issue.
The mux and convert to MEL went just fine, so did the ffmeg demuxing. And it is an FEL title. (Apocalypse Now Final Cut).

I've tested notrious MI:Fallout scene on Shield TV and ... nope, still reddish blocks.
Files are here https://gofile.io/d/JZUXU6

This leads me to think that the Shield issue is not FEL or MEL related, but that DoVi metadata is not properly handled by decoder
Thats why some FEL/MEL titles have no issues while other have.
But without proper tools it's impossible to catch a difference in meta.

Posted: **Sat Oct 03, 2020 8:37 am**

yusesope, you've created MUX_AND_CONVERT_TO_PROFILE_81.bat in your new v0.0.4_BETA_TEST.

Code: Select all

python-3.7.6.amd64\python.exe src\app.py -mux -mode 2

but that's equal to mux.bat now.
I think you should delete -mode 2 in mux.bat so that mux.bat is the same as in earlier releases.

Zidoo Z9x VS10 :

afss, post: 134440, member: 19783 wrote:BTW, I have placed this question on another thread, but in case Mark (or somebody else) knows the answer. How can we find out what the player is actually doing, while using LLDV ? I mean, I think I have properly converted a MEL DV bluray to MKV, and when I play it back on the Z10 pro, I am unable to verify if the conversion was sucessfull and the player is actually using the DV data on the file, or if it is simply treating it as HDR10.

On the OPPO 203, for instance, the info window shows how the source file is being interpreted as (DV, HDR10, SDR). Maybe there is a way somewhere to verify what the player is doing on the Zidoo as well.

Markswift2003, post: 134446, member: 21473 wrote:This is something I'm a bit unclear on too - As far as I know, the player natively supports Profiles 5, 8 & 9 which are all single base layers plus RPU (Reference Processing Unit = metadata interleaved in the video stream).

But as we know, Profile 7 encoding is now leaning more towards MEL than FEL and with the Enhancement Layer omitted, that is simply a standard 10-bit HDR10 stream with a Dolby RPU interleaved (plus HDR10 SEI for backwards compatibility).

So when VS10 is playing out P7 MEL it's either HDR10 with HDR10 SEI converted into P5 or it's HDR10 with Dolby RPU converted into P5 which would basically be a colour map from BT.2020 to IPT since the RPU is the same for both. It all comes down to how the PQ curve is produced on the output - in other words, the tone map.

Unless of course you do as we are doing and introduce BT.2020 primaries in the Dolby block in the EDID, in which case there's no colour map needed so nothing really changes.

I'd like to think it's the latter but as always Dolby are playing their cards very close to their chest and I can't find any technical docs regarding how VS10 deals with this but it would make sense that the RPU is used.

As usual, amazing work yusesope! Thanks a lot!
I've tested the new SL method with several FEL and MEL titles and all of them worked perfectly both on M9702 and C8's internal player.
