Dolby Vision now possible through MP4 Mux.

[RESET_9999]

But i not have the mkv file.I can demux m2ts file from bluray to obtain DTS audio track with TS MUXER, and then?

just change the input extension to whatever your source is.

Code: Select all

ffmpeg.exe -i input.m2ts -map 0:1 -c:a eac3 -b:a 1536k -c:s copy output.mkv

-map 0:1 is the track this cmd will encode... If the bluray has dolby vision, it will be -map 0:2
0 being video 1
1 being video 2
2 being english audio

Tested “RPU-FEL Test DT DL p7” .mp4 and .ts, both show same images ( as your post ), but .mp4 stuck at 0,20” while .ts play entitely….so, DV work?

You're supposed to see flashes if the rpu is used, and a video on top of the red image if fel is used...

- DTS (HD*) 5.1 & 7.1
— My Soundbar only shows “DTS Audio” for HD and compressed but by playing back the 5.1/7.1 HD Test files the channels are mapped correctly and it is highly likely passing through the right format using OMX.amlogic.audio.decoder.dtshd

You really just want the DTS-HD bitstream passed through, not decoded, right?

Seems likely that the Amlogic DTS-HD decoder takes DTS-HD input but only decodes the lossy DTS core.

That's how, e.g., Plex's DCA decoder works.

Otherwise they would need to be paying for a hardware decoder license.

But ultimately, you don't want it decoded by the stick, you want it passed through for the soundbar to decode.

Since your soundbar is reporting DTS, seems like the Amlogic is decoding and re-encoding to DTS at worst, or only the DTS core is getting pass through at best.

I assume you have this plugged into your LG B1 and it's passing audio to the soundbar via eARC? Does the B1 pass lossless audio from an HDMI input out via eARC?

On the Sony A80J/A90J, it supports lossless audio over eARC, but only when played back via internal apps. The Sony OLEDs won't take lossless audio from one HDMI port and pass it out through to the eARC HDMI input. TrueHD audio doesn't play at all and DTS-HD only passes through the DTS core or doesn't play, either. So that may be what's happening here if the B1 behaves the same way.

OK, so you want to convert P5 to P8.1 but Apple is using an odd "max_display_mastering_luminance".

Please tell me the way convert P5 to P8 of this file.
This file have not info of Mastering display luminance, Maximum Content Light Level, Maximum Frame-Average Light Le

You can extract the values from the original RPU and see what it's using.

Or maybe quiet_void or RESET_9999 can confirm what happens if you specify 0 for MaxCLL and MaxFALL when editing the L6 data. Some of RESET_9999's tutorial videos show leaving those values at 0 when editing the L6 data with dovi_tool.

Code: Select all

dovi_tool extract-rpu video.hevc
dovi_tool info -i RPU.bin -f 0

That should show the MaxCLL and MaxFALL values already in use. Copy those to your L6.json file, and just set the min display luminance value to 50 and the max display luminance value to 1000 to correct those values.

Then you can follow the remaining steps to edit and inject the RPU from my earlier post.

[RESET_9999]

yeah , I don't edit the L6 metadata when I go from p5 to p8. (unless the metadata is invalid like some of the iTunes web-dl)

Is it possible to create BDMV folders or ISO files with Dolby Vision Profile 8 files and have them properly play back on a UHD Disc player, like an Oppo? Or is profile 8 not supported by the BD player spec?

I am asking, as I only have an Nvidia Shield, x700 and an Oppo 203 clone, and from what I have gathered, the Shield does not have accurate coloring for Profile 8 DV.

I don't know about the other players, but the X700 wouldn't play P8 in BDMV format in my testing. It locked up the player with a black screen.

The only DV profile supported by UHD BD is P7, with either FEL or MEL.

The best combo of DV P8 + lossless audio + subtitles + FF/RW support on the X700 is to use tsMuxer to create m2ts files.

I also asked about this a week or so back, and to use BDMV format, we'd need a legitimate EL with the same frame types in the same order as each frame in the BL in order to carry the RPU. P7 doesn't support BL+RPU, it needs BL+EL+RPU.

I haven't seen anyone successfully accomplish that yet.

quietvoid mentioned he might think about adding support for generating an MEL to dovi_tool, which would make P8 or P5 conversions to P7 possible.

That would be great!!

So I read that for the x700 to play dolby vision m2ts without issues we need to remux it to bluray folder structure and put it in the root folder.

What about non dolby vision movies, i.e. hdr10 movies? Do we need to the same thing? What if the file is not m2ts but remuxed mkv, will the hdr10 and dolby atmos still work on the x700?

Yes

Which I think they do with this stick. DTS-HD branding/license info is all over the packaging and info material for this stick. Also the DTS-HD source I used didn’t have the lossy core which might explain why DTS:X doesn’t play/bitstream but DTS-HD MA does.

But ultimately, you don't want it decoded by the stick, you want it passed through for the soundbar to decode.

Since your soundbar is reporting DTS, seems like the Amlogic is decoding and re-encoding to DTS at worst, or only the DTS core is getting pass through at best.

With the sound settings set to Bitstream it seems to do the right passthrough when the edid supports it else it probably HW decodes that with any source that is “supported”. Not using Bitstream just reencodes everything to Dolby Digital.

I assume you have this plugged into your LG B1 and it's passing audio to the soundbar via eARC? Does the B1 pass lossless audio from an HDMI input out via eARC?

On the Sony A80J/A90J, it supports lossless audio over eARC, but only when played back via internal apps.

TrueHD audio doesn't play at all and DTS-HD only passes through the DTS core or doesn't play, either. So that may be what's happening here if the B1 behaves the same way.

I have the devices directly connected to the Soundbar bc I know the LG B1 doesn’t passthrough any DTS (so stupid but that’s a another discussion) over eArc.

So I read that for the x700 to play dolby vision m2ts without issues we need to remux it to bluray folder structure and put it in the root folder.

If you want to play a DV P7 file that was originally ripped from a UHD BD, then yes, you want to remux back into BDMV format and put the folders at the root of a USB drive.

If you want to play a DV P8 file that was converted from P5 (streaming services) or P7 (UHD BD) then you want to remux the file into a single m2ts file and can place the file anywhere on a USB drive.

It's possible you can also remux DV P8 files into BDMV format in order to preserve chapters. I had this work a while back, but I haven't gotten it to work more recently. It just locks up the X700 with a black screen.

I did some testing as I was trying to figure out what the X700 supports. You can see that here.

What about non dolby vision movies, i.e. hdr10 movies? Do we need to the same thing? What if the file is not m2ts but remuxed mkv, will the hdr10 and dolby atmos still work on the x700?

The X700 should play back HDR10 from an mkv file, but I don't think Dolby Atmos is supported. It has been a complaint registered with Sony for years and I don't believe they've done anything to add Atmos support for mkv.

This is RPU info of file.

Yeah, I expected to see values for MaxFALL and MaxCLL and some incorrect values for the max/min display luminance.

That RPU isn't showing it there, but perhaps dovi_tool fixed it on extraction.

Maybe now try just converting that RPU.bin file to P8 with "mode: 3" and see if it works when re-injected.

Oh, nice. I missed that in the product info. It sounds like you've got it figured out and I'm not really helping. It's just odd that the soundbar would report DTS when DTS-HD is supported.

Maybe this has reached the limits of my knowledge of DTS-HD, but I thought all DTS-HD streams are formatted with a DTS lossy core and lossless extensions; that it's part of the file format. There's such a thing as DTS-HD without a DTS core?

Thanks for your reply. How do we know which one is DV P7 and which one is DV P8? As for mkv file, can't I just remux it to bmdv format and then the x700 will be able to play it with atmos?

Created some powershell scripts to handle MKV to MP4 with dolby vision. Hoping others can get some value out of them.

I'm new here, sorry if I ask a question that maybe has already been answered, but I can't find a way to do what I want, so I'm probably not looking at the right styff...
I have a DV MP4 file working fine via USB on my LG oled. Point is I want to add another audio track/different language to it.
How do I do that? Which program can I use to remux the MP4 correctly with the added track...?

Thanks to anyone who can help me.

It depends on what you want the resulting filetype to be. If you're looking for a ts, m2ts, ISO, Blu-ray folder you can use TS-Muxer.

If you're looking for an MKV, you should use ffmpeg to convert the mp4 to an mkv and then you can use MKVToolNix to multiplex the new audio track with the MKV you created with ffmpeg.

I move away from MP4s, so I can't recommend anything if you're looking to keep the file as an MP4. Others will need to weigh in.
