Dolby Vision now possible through MP4 Mux.

[RESET_9999]

I used your script of the latest version of "DoVi_Scripts_1.9.0.2.beta_MKV" at the moment.
SiC's BCORE video was used, which has no contrast problem unlike ROCCaT's BCORE.

My guess is that SiC changed the full range flag for the container only(with mkvtoolnix) and not at the bitstream level and ffmpeg still thinks the color range is FULL when it export the screenshot.

Also, when using the 6-6-2 option, an error appears.

oops..
try DoVi_Scripts_1.9.0.3.beta

I don't think so.

And there is exactly the same problem, if you need to provide screenshots.

Well I use 6-8-3 every day, it doesn't tone map to SDR... Your Bcore comparison sure looks like full vs limited range.

your HDR10 pic is wrong somehow.
it's working just fine and it's the same as MPV on my end so I don't know.

Yes, I was wrong that the problem is not DV-P5 but HDR, I saw it by taking a screenshot in MPC. After that I tried 6-8-4 option for magic.mike.2012.hdr.2160p.web.h265-slot.mkv and got normal HDR screenshots.

Thanks! But I noticed, the --dvh1flag option is not working. This would be necessary for playback on Apple TV (with tvOS 17). Can you fix it?
This solution works until: https://github.com/rixtox/mp4dovi

but why use the mp4muxer at all for ATV or new TV (2019+) when mp4box can mux directly lossless audio + subs + chapter?

My goal is, create a file that works well on old LG and Apple TV.

Hi all,

Has anyone experienced the NOKIA Streaming Box 8010 regarding Dolby Vision and audio output?

Hi,
i want to remux a UHD FEL from mkv to mp4 (for LG).

the correct format (made by the ape) is:


but I want to remux it without the ape, just with dovi tool & mp4box.

mp4box -add BL.hevc -add EL.hevc:dv-profile=7 -add 1.eac3#audio:lang=ger:name="AC3 5.1" -new 2.mp4

but I always get version0:


any idea how to say MP4box to make "dvhe.07.06" ?

Hi RESET_9999,

When encoding DDP from THD/DTS using your script (ffmpeg) the result is a DDP 5.0(side) channel layout. This layout is missing the LFE (subwoofer) channel.

My understanding is that since the goal is to encode DDP 5.1, one can add either the option "-channel_layout 5.1" or "-channel_layout 5.1(side)" to the ffmpeg command. The LFE (subwoofer) channel is then included in the channel mapping of the output.

ChatGPT tells me: "In a 5.1 setup, the rear channels (RL and RR) are directly behind the listener, creating a typical surround sound experience. In a 5.1(side) setup, the surround channels (SL and SR) are placed to the sides of the listener, rather than directly behind. This configuration is intended to provide a wider and more immersive surround sound experience, especially in setups where it might be difficult to position the rear speakers effectively.

When using ffmpeg, it is essential to choose the correct channel layout based on your speaker configuration and the desired audio experience. If you have speakers positioned behind the listener, you should use the standard 5.1 layout. If you have speakers on the sides, 5.1(side) is more appropriate. Using the wrong layout can result in audio being sent to the wrong speakers, leading to an inaccurate surround sound experience."

Maybe something to complete your script with?

Also, thank you for all the time you spend on the script and answering questions here, I'm still polling this thread for new stuff to learn almost every day, and I've been lurking around since it was first created

I had this issue with some newer versions of ffmpeg and I thought it was fixed in the version I use (02-27-2023) right now.

Try this version: https://drive.google.com/file/d/1rzHhl_ ... sp=sharing

I didn't realize it may had todo with an issue with ffmpeg itself, anyways, I have been using a newer ffmpeg version

The first is the one you linked to, the second is the one I've been using.

C:\Users\Andreas\Downloads>ffmpeg -v
ffmpeg version 5.0.1-full_build-www.gyan.dev Copyright (c) 2000-2022 the FFmpeg developers
built with gcc 11.2.0 (Rev7, Built by MSYS2 project)

C:\Users\Andreas\Downloads>D:\Video\tools\ffmpeg-5.1\ffmpeg.exe -v
ffmpeg version 5.1-essentials_build-www.gyan.dev Copyright (c) 2000-2022 the FFmpeg developers
built with gcc 12.1.0 (Rev2, Built by MSYS2 project)

and i had to add this option to get the 5.1 output instead of 5.0.

Ill try with 5.0.1 and see what happens. If there was an issue fixed, maybe they broke it again with a more recent change.
