So if I understand correctly we still didn't get single track video with full EL layer (profiel 04 or 06) to work on LG C# without stuttering?

Correct, that is my understanding as well from the latest tests we have done.

Does the profil change the DV's "quality"?

The NEO U22-XJ is now officially out. Anyone gonna pick one up and test it's DV functionality?

Patiently waiting to see what this supports also, but I'm not expecting anything above what we have now with the shield.
Although if this can produce accurate DV color as apposed to the shield that might be worth it.

Strange as my mode 1 "BL+EL+RPU" merge of Gemini Man (FEL HFR) did trigger DV and played smoothly on my C8 when I was using an older rev of TsMuxer.
See my post: https://www.makemkv.com/forum/viewtopic ... 295#p86295

The older rev of TsMuxer was showing profile 08.09.
That makes me wonder whether the TV was actually processing the full enhancement layer or perhaps it was only using the metadata (due to the profile saying 08).

Who kbnows

Anyways I've recompiled TsMuxer with the last two changes of jcdr248's PR: https://github.com/justdan96/tsMuxer/pull/269
And I tried to create a dual track TS file of Gemini Man, but that only triggers HDR10 on my C8.

Still hoping to find a way to enjoy the full enhancement layer on the C8 while retaining the TrueHD audio (for storage/collection purposes only, I know the C8 wont play HD-audio due to the lack of e-ARC).

Still hoping to find a way to enjoy the full enhancement layer on the C8 while retaining the TrueHD audio (for storage/collection purposes only, I know the C8 wont play HD-audio due to the lack of e-ARC).

Not possible ATM - see response below.

I made the comment that tsmuxer was assigning profile 7.05, while mp4muxer was profile 7.06 - I do not know if that matters.

@Angryunibrow it should be 7.06... I'll fix it. However the level is only related to pixel rate, marking 7.05 does not make any difference if your SoC can play 7.06 pixel rates. The most obvious reason why the TS plays on Blu-ray players only is the HDMV (Blu-ray) descriptors. Standard ETSI descriptors might allow DV but would remove compatibility with PGS, ac3/eac3 and ac3/TrueHD.

The NEO U22-XJ is now officially out. Anyone gonna pick one up and test it's DV functionality?
http://shop.minix.us/neo-u22-xj

Patiently waiting to see what this supports also, but I'm not expecting anything above what we have now with the shield.
Although if this can produce accurate DV color as apposed to the shield that might be worth it.

The devs specified it supports dual layer, and it's not capable of playing HD from Netflix or any other streaming service so the only thing it can play is rips. I would assume if they're gonna pay for the license they'd implement it right. I'm gonna order one when I get my trumpbux so I'll test it and post results here.

Do you have a link to them saying that (not that I do not believe you) I would like to see what the exchange was when that was mentioned.

IF, and its a big IF this does support Profile 7, I would think we would need decrypted BDMV folder playback support. Then we do not have to worry about trying to mux these files into something that is not fully supported and losing ATMOS and everything else.

We will see I guess.

It was probably from this vague post here: https://theminixforum.com/index.php?thr ... post-17736

The question I have is whether this dolby license fee is an encompassing license that allows for decoding of all profiles and then it's up to the hardware to be capable of dealing with the individual profiles, or is the licence fee broken down by individual profile support. If it's the latter, the skeptic in me finds it hard to believe that any company would pay the profile 7 dolby license fee for a streaming-only device just to satisfy the niche situation we have here. Normal consumers are not going to encounter profile 7 outside of playing it from their physical uhd disks, hence why it's only mostly blu-ray players that have the capability to do so at the moment (LG C# TVs are certainly an exception).

like I mentioned in my follow up post on that link, it either has to do profile 7 or it's pure marketing BS. otherwise I really just don't get it. profile 4 or 5 support will do nothing for consumers as it's a non-certified device so it won't even do Full HD in streaming apps, let alone 4k or dolby vision lol. so either marketing is trying to sell it on the sham that the SoC can physically do dv and android 9 os has a force dv setting that fakes it for everything in the gui, or they will actually support profile 7 so consumers can play their backups. They claim they have a paid dolby license, but would Dolby really grant a license to a non-certified device on good faith that minix customers would only watch legit backups and not commit piracy?

Nvidia devs said that Dolby will not licence full profile for set top boxes as they see the only Avenue for that is piracy.

...
means there is no backward compatibility. SDR is 1, 1, 1, HDR10 is 9, 16, 9.
....
Primary Dolby Vision PID Carrying a non-SDR and non-HDR Compliant BL substream
The value of stream_type shall be set to 0x06 (indicating PES packets containing private data).

I think what you think (in fact I had written despite color_description_present_flag = 0 and chroma_location_info_present = 0)
But then I analyze the LG demo (I think LG has all the hardware and software certified by Dolby) and I see this:

stream_type shouldn't be 0x06? (I don't think it's because of the presence of HEVC_timing_and_HRD_descriptor in place of 0x0504444F5649)

The way FEL is triggered in the RPU of profile 7 and of profile 4/6 seems to be different. So it is not as simple as copying the EL/RPU from the second track to the first.
...
Edit: if anyone is interested in parsing RPU information https://patentimages.storage.googleapis ... 9132A1.pdf

About 20 days ago I posted the comparison between two RPU headers (HERE). Out of curiosity, I analyzed an RPU of the LG demo (BL+EL+RPU, dvhe.04.06) and the header is identical to that of the MEL stream (from a UHD-BD).

I didn't go beyond the header because that document is a nightmare.
I don't think current RPUs are implemented as described in the patent.
A simple example, considering the final sequence 0b10000000 (0x80) as rbsp_trailing_bits(), the previous 4 bytes should represent the CRC value (calculated on the entire rpu_data () excluding rpu_data_crc32).
The calculated CRC32 value never corresponds to that present in the RPU.

As for the FEL layer, in the case of profile 4, a device must control and must flag, in case of profile 7 the device can control and can flag. However, the variables to be checked are the same.

The fact that on LG televisions a BL+EL+RPU file goes jerky (unlike a simple BL+RPU) could be due precisely to the presence of the FEL layer which saturates the decoder buffer.
My dvhe.04 files are High Tier 5.1 (both BL and FEL/MEL because they come from a UHD-BD)
From the official Dolby documentation:

Code: Select all

In certain cases, the Dolby Vision specification imposes tighter constraints on the maximum tier bit rate and
the maximum decoded picture buffer size, as compared to the HEVC Main10 Level 5.1 specification.
See sections Dolby Vision levels and Limitation on decoder buffer size.

When playing back the DV4 file, the renderer actually lists the codec as dvhe.04.06, but nothing for the DV6 file.

Thanks @shawnc22.
I'm sorry guys but the latest version of Exoplayer (2.10) does not support profile 6. There is an article about it on the developer blog (HERE) and checking the code (HERE) it shows the same thing!

Strange as my mode 1 "BL+EL+RPU" merge of Gemini Man (FEL HFR) did trigger DV and played smoothly on my C8 when I was using an older rev of TsMuxer.
See my post: https://www.makemkv.com/forum/viewtopic ... 295#p86295

I followed the exact same steps in your post but Gemini Man still stutters every 2 seconds on my oled C9. The file is stored in an external hdd connected to the tv via usb and played using the tv internal media player.
