Dolby Vision now possible through MP4 Mux.

[higher]

Got home and tried the nightly tsMuxer build you posted earlier and it works, ts is now triggering DV on the TV. Thank you for the link!

[cannibalist2]

Guys thanks for all the information you shared so far. I started to reading all of the pages for making dolby vision rips properly. But I need to ask you some questions before that. I have LG G1 and I'm gonna use native plex app. (I don't have shield or apple tv)
1. Does this tv support only mp4/m2ts/ts and single layer dolby vision?
2. My pc doesn't have a strong cpu. Does making dolby vision rips take too much time?
3. I want to get best picture as possible. Is plex app enough or do I need shield pro?

How can i see if a mt2s or mkv have hdr10plus metadata'?

Trying to find a Alien 1979 hdr10plus disk backup version...

It should be apparent in mediainfo

[thetoad]

are hdrplus10 and dovi rpu (i.e. not enhancement layers) metadata effectively similar information? could one conceptually convert one to the other? (i.e. assuming one has an hdr10 base, could one convert hdr10plus to give a dolby vision only tv dynamic metadata and vice versa for an hdr10plus tv).

or are they totally different (or different enough) that this isn't possible. just wondering if anyone has thought about this?

Going from HDR10+ to Dolby Vision can be done partially, since both include the image analysis info (min/max/avg luminance). The rest of the info is incompatible without heavy calculations.
Going from Dolby Vision to HDR10+ isn't really possible because HDR10+ requires some information (luminance percentiles per shot) that's not present in Dolby Vision, and would require analyzing the image and more calculations..

Not to mention most of the steps for calculations are proprietary.

hulu recently added dv and hdr10plus support and it looks like they are all in profile 8 DV

Code: Select all

Dolby Vision, Version 1.0, dvhe.08.06, BL+RPU, HDR10 compatible / SMPTE ST 2094 App 4, Version 1, HDR10+ Profile B compatible

Seems hulu has no extra HDR encoding so would it be possible to demux the HDR part from the hevc stream?
I found out that this dovi_tool has a demux option and now i got 2 files BL.hevc and EL.hevc. The BL.hevc seems to be the HDR part, is that right? Or is there another way to force HDR playback instead of DV?

[MastaG]

EDIT:

I really hope somebody can answer this.

Does the Plex app for Shield support DV from MKV containers?
If yes, which profiles?

And what about the LG WebOS Plex app?
I believe it only supports DV profile 5 (MEL) from MKV containers right?
What about .TS containers?

I'm looking to store my videos in a container which can also carry lossless audio, but is capable of triggering DV on both LG TVs and the Shield using Plex.

I know LG only supports AC3, but that's no problem because I can just store the TrueHD track as the second one.

The BL.hevc seems to be the HDR part, is that right?

Yes, the BL.hevc file does not contain any Dolby Vision data, but it does still fallback to HDR10+.

Hi! I am newbee here so please bear with me. I've experimented with dovi_tool a little bit but failed every time. Obviously I am doing something wrong so I would appreciate your help. Thank you.

Here are my exact steps (using Windows 10 Pro 64bit and everything like source files and dovi_tool.exe/ffmpeg.exe are inside main folder):

01, ffmpeg -i DV_WEB-DL.mp4 -c:v copy -vbsf hevc_mp4toannexb -f hevc - | dovi_tool -m 3 extract-rpu -
02, ffmpeg -i HDR.mkv -c:v copy hdr.hevc
03, dovi_tool inject-rpu -i hdr.hevc --rpu-in RPU.bin -o output.hevc
04, final output.hevc is muxed in latest MKVToolnix with sound and subtitles from HDR.mkv

There is a difference between DV web-dl and remux HDR10 file in frames but if I understood correctly, dovi_tool should adjust it automatically for metadata. Am I right? Using the latest 0.5 version.

I do not have any errors either in ffmpeg or dovi_tool. All is going smooth. Except when I try to play the final file in either mpv or mpc-hc I see glitches - for example in the beginning when the the logo appears, the picture will freeze for a couple of seconds and the sound is continuing. At that time the glitch in small rectangle in left upper corner will appear. Here are examples:

Just got a Zidoo z9x player.. works great for any file I played but tv-led has the wrong bt2020 flag as well SMH
https://slow.pics/c/8zWhGixS




The x700, the Shield, the appleTV, the firestick, Chromecast, Ugoos:



colors are mostly accurate, still have to check DV but at least there is no red push on Doctor Sleep. if they fix the bt2020 flag, it is a better device than the Shield IMO

HDR10 422 12bit

damn with all the players you've bought recently, you should've just bit the bullet and gotten one of the oppo clones

[RESET_9999]

yeah but just like the x700, the oppo cant play cropped DV properly. with all the appletv and amazon(hdr10+ to DV) content , it was a problem.

And now I can watch all the mel DV content via my network and only use my hdd /x700 for FEL. It's much more practical now. plus I get to reduce the amount of TS files in my library ( i prefer all MKV)
zidoo works surprisingly well, literally played every single file I tried.

Hi, have you installed latest firmware?
On your test pic it shows the BT2020 pic with 25hz, did you try 23hz?
Post in the Zidoo forum, Mark Swift has a Vertex2, if it is a bug he will get it fixed.
I’m mostly pleased with my Z9X after the latest firmware updates, it was a bit buggy for a long time after release.

Hi,
yep, it's the first thing I did. I updated to the latest firmware via the settings. Is there a BETA firmware that I need to install manually?
Yes I tried many different files (23 /24hz), all the same. You can see the flag as well when you press ''OK'', the zidoo info menu shows RGB bt2020 signal.

I posted my finding on the zidoo forum thanks

Also, I personally don't care about this because I will use it for DV only but I noticed a severe black crush in HDR10/SDR using the Spears and Munsil black level pattern.

Have you tried using mkvextract instead of ffmpeg for the HDR10 base layer demux?
If there are issues with the injected file, they are probably present in the original demuxed bitstream.
