Why tv should only support single layer "Netflix DV" when they can decode dual layer DV ?tr000 wrote: Sun Jul 21, 2019 9:24 am ... but TVs are only supposed to support dvhe.04.07/dvhe.05.07 ...
It's because the mkv container only supports elementary stream playback, so a dual layer dv mkv will disregard the enhancement layer. the Matroska team is currently working on an update that sees the second stream. if you could put a single layer DV stream (like the LG Demo .ts or DVDFab .mp4 files) into an mkv without losing the rpu data it would play in DV on any device that already supports dvhe and you'd get the benefit of full hd-audio. that's the problem right now though; there's no software to rip single layer to DV or convert single layer mp4 to mkv without losing rpu metadata and reverting back to just main.10 hdr :/h2owater wrote: Sun Jul 21, 2019 11:56 am just curious why no official specs for DV inside mkv container ... is it because DV is not fully understood (lack of available documentations)?
i am not talking about playback yet ... just spec to include DV in mkv (mkvtoolnix, as most of you know, can put DV stream inside mkv ... obviosly nothing plays it ... and obvioysly it is not officially standard yet)
many years ago ... makemkv was first to offer 3D ripping to mkv ... nothing played it for years ... but it was fine ... as was able to rip 3D disc in hope future playback will become available ... which it did eventually and no reripping was necessary
this DV is painful ... ripping withot DV to mkv is sure way needing reripping when DV is supported ... same as muxing DV stream with mkvtoolnix (it might not be the way mkv will decide to hold DV data)
so again ... why no official spec to include DV in mkv? (once this is done then implementation of playback can start happening ... withot this ... its dead end atm)
Maybe because Dolby said so? It is not so simple as profile 5 not having dual layer support. Profile 5 can certainly have two layers but a PQ function is used. Profile 4 supports EL but at a lower resolution. It is not "Netflix DV" because there's still two 10-bit layers combined by the TV either with EL or PQ to create 12 Bit Dolby Vision. Streaming is 10 bit and is a completely different spec.daddy wrote: Sun Jul 21, 2019 11:29 amWhy tv should only support single layer "Netflix DV" when they can decode dual layer DV ?tr000 wrote: Sun Jul 21, 2019 9:24 am ... but TVs are only supposed to support dvhe.04.07/dvhe.05.07 ...
Where did you see that dvhe.07 should only be decoded by UHD BD players ??
No, backward compatibility occurs for all lower levels (see Annex III). The document clearly states "Every Dolby Vision playback device must pass Dolby Vision system development kit certification. During the certification procedure, the chipset implementing the Dolby Vision decoder will be tested against the advertised device capabilities, and Dolby will approve the device capabilities" dvhe.04.07 and dvhe.05.07 are the only "Device Capabilities" mentioned for chipset-based TVs.daddy wrote: Mon Jul 22, 2019 6:06 am I read the Dolby carefully and i do not see where Dolby wrote that tv should not allow decoding dvhe.07.
Dolby only wrote that "This table lists example devices and their capabilities specified by Dolby Vision profiles and levels strings".
Do you know that some UHD Blu-ray player can decode dvhe.04 - dvhe.05 ?
UHD BD players are only supposed to support dvhe.07, no ?
This is right.tr000 wrote: Mon Jul 22, 2019 10:05 am dvhe.04.07 and dvhe.05.07 are the only "Device Capabilities" mentioned for chipset-based TVs
You are right, but it could also be lower since the device can advertise whatever it wants. DV4 can have dual layer and does play in 12-bit on my TV, so it's not the dual layer impeding compatibility. These are guidelines, in general I guess. We'd need to check the EDID info coming from the TV to confirm.daddy wrote: Mon Jul 22, 2019 5:43 pmThis is right.tr000 wrote: Mon Jul 22, 2019 10:05 am dvhe.04.07 and dvhe.05.07 are the only "Device Capabilities" mentioned for chipset-based TVs
But it simply means that a television needs to support dvhe.04.07 and dvhe.05.07 to be Dolby Vision certified.
And nothing prevents a manufacturer to go further and allow his television to read the dvhe.07.
This is what makes the différence between LG, Vizio (dvhe.07 dual layer compatible) and Sony, Panasonic, Philips, TCL (dvhe.05 single layer compatible)
from Annexe II
"If a Dolby Vision playback device supports Dolby Vision profile 7, it can check for these values in
the reference processing unit of a Dolby Vision bitstream. If the values are not exactly as shown
for all three channels, the device can flag the bitstream as a Dolby Vision profile 7 full
enhancement layer bitstream; otherwise, flag the bitstream as profile 7 MEL."
The documentation don't say "if a BD UHD player (which, for you, should be the only device to support dvhe.07) ..." but instead Dolby wrote "if a playback device".
This mean it can be any device, a bd uhd player, a tv box, a tv that supports dvhe.07.
give this a whirl:tr000 wrote: Mon Jul 22, 2019 11:27 pm Well, I thought I had it figured out but maybe not. The .MP4 the MP4 Muxing tool someone on here made played the video fine, but the audio was all messed up. Played fine for a few seconds, then there would be glitches and stuff. Tried doing it manually, same thing. Then I downloaded a REMUX and used the tool, the video was just black. Did it manually, and the audio was fine and it played in DV but now the video paused every couple of seconds. Ugh. Back to the drawing board I guess. Why does DV have to be so finicky?
I actually already tried it with DVDFab 11.0.3.1, the TV said there were no video tracks on the mp4. Did they add more options to the newer versions?Grencola wrote: Mon Jul 22, 2019 11:38 pmgive this a whirl:tr000 wrote: Mon Jul 22, 2019 11:27 pm Well, I thought I had it figured out but maybe not.

- grab the latest trial of dvdfab (you get 3 free conversions)
- click uhd ripper
- add your bdmv folder - it should automatically see
- dv and choose the mp4.dolbyvision profile (see that it did)
- click the little wrench beside the movie for advanced settings
- choose copy video box
- uncheck web optimized box
- click the dolby pulldown menu and choose single layer+rpu
- choose ac3 audio and up the bitrate to 640kbps
- hit ok
- click start
They did, yeah: https://m.dvdfab.cn/dvd-fab-new try the latest version with single-layer conversiontr000 wrote: Mon Jul 22, 2019 11:48 pm I actually already tried it with DVDFab 11.0.3.1, the TV said there were no video tracks on the mp4. Did they add more options to the newer versions?
Hm, I'll have to try it then.

I did some files using the latest version as per your guide. They play fine on Lg via plex server and also they play fine in a Panasonic Gx 800 and Dolby Vision logo pops up.. The interesting thing is that if DV is double layer they are played as HDR in Panasonic. So a step ahead.Grencola wrote: Tue Jul 23, 2019 12:19 amThey did, yeah: https://m.dvdfab.cn/dvd-fab-new try the latest version with single-layer conversiontr000 wrote: Mon Jul 22, 2019 11:48 pm I actually already tried it with DVDFab 11.0.3.1, the TV said there were no video tracks on the mp4.

good to hear. ya dvhe.05.06 is much more broadly supported than dv profile 7, so single layer DV should be the new focus for video files moving forward. I'm already working towards sneaking hd-audio into these mp4s so there's huge potential for full dv playback soon. you can try out a test clip in plex if you wantragico wrote: Fri Jul 26, 2019 8:17 pm I did some files using the latest version as per your guide.

Serviio do not recognize the files made by dvdfab so cant be used but Ples is Ok.
Thank you
