[DDVT Tool] Dolby Vision RPU Demuxing / Injecting / Editing.

For MP4 you need to use Dolby's muxer from 2018: https://github.com/DolbyLaboratories...3a8e3effff/bin

Either way it's best to stick to .TS with tsMuxer, it should be working fine.

Yep, can confirm, simply run the "hybrid" mkv thru tsmuxer, and create a .ts or .m2ts file, and the LG will display Dolby Vision.

Only problem I have is if you "jump" (forward or back) the playback from the remote, the playback will take a second or 2 to start to play, but HDR hasn't got that issue.

Attn -QfG-,

I have started using this tool again, after a long break, and the last build I used is #53

So I grabbed the latest build (#63.fixed) the other day, and when just simply wanting to extract the rpu.bin, it fails , however, #53 does the job, no issue

So I just got #60 & #62 (also noticed that there is a significant increase in the file size between #60 & #61.1, and then again between # 61.5 & #62.

#60 worked, #62 failed.

Am I missing something, or do I just need to keep using the older builds ??

Just fyi, that's all.

I need some guidance here. I have an Amazon firestick 4K max. I have an MKV file in 4K that's about 40GB in size. The playback is extremely choppy. I read that the Amazon firestick 4K max has trouble with files with both HDR10+ and Dolby vision. So I figured that was the issue (the other issue could also be streaming that 40GB is too much for the device to handle).

So I figured I'd use handbrake to shrink the size down. In the process of doing that I used this tool to backup the original (40GB) HDR10+ stream and remove the Dolby Vision.

I then used handbrake, only to find out it doesn't keep HDR10+, it reverts it down to HDR10. So I had this idea of injecting this newly compressed MKV with the original HDR10+ stream (using DDVT_INJECTOR) which was backed up by this program.

I tried doing that and it outputted a hevc file, rather than an MKV file. I guess I'm wondering if what I'm attempting is even possible (when I re-encode with handbrake, does that make it incompatible with the HDR10+ backup?)

Also, how do I get an MKV file? I figured the injector would inject the HDR10+.json file into the MKV and give me a new MKV file. Kinda lost as what I'm supposed to do with this hevc output.

Thanks!

AFAIK there are no issues with injecting DV/HDR10+ metadata into a re-encoded stream. You can use MKVToolNix to add the audio tracks/subtitles/chapters from the original .mkv along with the .hevc file and create a new .mkv.

Ahhhh, good call! Completely forgot about that program being able to do that. So I was able to do it and MediaInfo says "SMPTE ST 2094 App 4, Version 1" under "HDR Format". Does that look right? In the original file where I striped out the Dolby Vision it says: "SMPTE ST 2094 App 4, Version 1, HDR10+ Profile B compatible". What's the significance if it missing that "HDR10+ Profile B compatible" line?

EDIT: The original file also has these included entries while the newly created file doesn't:
Mastering display color primaries : BT.2020
Mastering display luminance : min: 0.0001 cd/m2, max: 1000 cd/m2
Maximum Content Light Level : 411 cd/m2
Maximum Frame-Average Light Level : 322 cd/m2

The TV can play such files but the problem is that they always play in HDR mode and cant trigger the TV DolbyVision mode .

I have both B8 and C2, and also Samsung models, and so far the only universal solution is to mux them into TS/M2TS.

Profile 8 mp4 will work on both new and old type of internal LG players, but the Codec ID must be dvhe. This tool will convert to mp4 with Codec ID hev1 which plays as HDR on the B8/C8. But dvhe is not compatible with non-DoVi devices such as Samsung AU9072.

Still, it will be a great addition to add the option to chose the Codec ID when converting to mp4.

I'm not really sure how to interpret this. Does it play as you expect it? One possibility may be that what MediaInfo shows (info about the .mkv container) does not match the underlying .hevc stream. Another possibility, since display mastering and MaxFALL and MaxCLL are all HDR10 info, is that Handbrake stripped out the HDR10 metadata and left you with a PQ10 .hevc stream.

I want to make an HDR10+ hybrid -- HDR10+ from the web, injected in the bluray. The HDR10+ from the web is 40 frames behind the bluray. I know there are ways to edit/sync DV RPUs to the base layer, but are there similar tools/methods for HDR10+?

[GodzilaAvenger]

I think you can enter the frame delay (positive or negative) in the DDVT_INJECTOR script.

The latest HandBrake version will preserve HDR10+ and Dolby Vision when using the x265 10-bit encoder. So either something went wrong or who knows, it's hard to say without additional info.

Thank you very much for the info ! Please can you share which tool (source) and command do you use to demux such hybrid .mkv files into .mp4 (.m2ts) dvhe Codec ID ?

Thank you for the support but can you share the command after mp4muxer_64bits.exe please ? And i originally have just hybrid .mkv but not .mp4 . Should i first convert it in .mp4 ?

[cool advertise]

to -QfG-
I would like to point out, that the DDVT_MKVTOMP4.cmd script of your tool, when converting an mkv file that has chapters, to mp4, loses the chapters in the conversion...

The problem is that when i try to add the such hybrid .mkv files into TSMuxer i always get this error:



with other kind of .mkv files i dont get such error...

I doubt if tsMuxer 2.6.12 accepts Dolby Vision video. Try latest nightly builds.

Thank you - i got it ! The .ts file is ready and waiting for me to back home and try to play it on the C8 TV ! I hope it will works this time !

Very very interesting. Looks like you pointed me in the right direction. I used H.265 10-Bit (NVEnc) instead of H.265 10-Bit (x265). My GPU compresses in 30-50 minutes rather than a bunch of hours via x265. That's why I used NVEnc.

But testing out both of them using the preview encoding option on Handbrake (encoding a 5 second clip) and dragging that output into MediaInfo, the NVEnc is stripping out the HDR10+ (SMPTE ST 2094 App 4, Version 1, HDR10+ Profile B compatible) and reverting it down to HDR10 (SMPTE ST 2086, HDR10 compatible)

I even tried fooling around with the "Filters tab" and turned on Colourspace to "BT.2020". That definitely was no good. All the HDR10 data gets removed in the section in MediaInfo.

For future time travelers.
Set Video Encoder to H.265 10-bit (x265)
Set Encoder Profile to Main 10, Encoder level to 5.1
In the "Summary" tab make sure "Passthru Common Metadata" is checked.

That worked.

So i tried to remux the hybrid .mkv file with newer version of tsMuxer into .ts file and finally my LG C8 plays the file into DV mode ! Now the only problem is that for some reason the .ts file rewind forward and backwards dont work and the movie has wrong duration time . Can this be fixed somehow ?

[GodzilaAvenger]

One thing that may help is checking the timestamps of the .hevc stream with ffprobe. If there's something weird going on you can rewrite it with ffmpeg genpts.

Transport Streams do not have an Index so they are not seek-able and their total duration is unknown unless parsed completely.
