Official Dolby Vision MKV spec support

[bobbymkV]

Awesome, thanks for that. Did not realize that ATV only does lossy.

What are you using Spatial Audio on?

I bought Airpods Max just to try it out lol. I've been looking for really good TV headphones for quite awhile now as I have shared walls and this combo did not disappoint, which is good as it just got implemented. Even 5.1 audio sounds really good with spatial audio.

Overdue to try that!

Sorry one more repeat of a question I asked earlier - are the files you are using just single layer .mkv files?

Yes, they would all be single-layer. Mind you I'm just getting back into the Apple TV just for spatial audio, so I don't know much about how to get Dolby Vision working on it. My assumption is it will only work for streaming services or files ripped/pirated from streaming services and played back with Infuse or MrMC.

Dumb question.

Does my MKV rip contain Dolby Vision enhancement layer?

Screenshot -> How it looks in MakeMKV latest. It's showing Dolby Vision FEL.

However, MediaInfo doesn't show that (note that the mkv was ripped using lib 1.15.1)

Wondering if the mkv really contains Dolby Vision layer or not?

I think you have to re-rip with a newer version of MakeMKV. There was a version that saved the DV data in a non-standard way that subsequent releases of MakeMKV could process and turn into the 'standard' way to store DV in a .mkv file. I don't remember if 1.15.1 is new enough, however. You also have to have a new enough version of Media Info to see the DV data in a .mkv file (20.09 or later: https://mediaarea.net/MediaInfo/ChangeLog). I ripped my copy of Atomic Blonde with 1.15.4:

Just to say that I was able to play a MakeMKV 1.16.3 generated file on my M9702 in Dolby Vision.
Had to remux it to a .ts with tsMuxeR first, which produces a 3% bigger file.

But it's way more convenient than using a full rip (no stupid menus, easier to add subtitles etc.), and it still plays with Infuse on Apple TV 4K (in HDR10), and probably other players too.

Very good news!

Hey! I have a chinoppo as well.
I did the exact same thing as you yesterday without seeing your post. How strange.

I think you missed out some steps in your method though. With your method, you lose the dolby atmos lossless track file.
You need to use a program called eac3to to add the dolby atmos track back in before you mux in .ts.
Also did you tick enable HDMV descriptors on tsmuxer when you made the .ts file?

When I did it without ticking, my .ts file was stuttering like crazy on M9702. With it ticked, no problems.

You're doing it right, both layers are stored in the single video track.

Got it. Thanks!

Now, if I want to reduce the overall filesize from ripped from disc size of 48+ GB, can I send the whole MKV file through Handbrake or will I have to separate the layers of the video track and only run the BL through so as to not ruin anything for DV?

I doubt Handbrake can be used for UHD as I don't think it can do HDR. In any case, the layers must be separated as only the BL can be re-encoded.

What I do is:

1. Rip to folder using MakeMKV.
2. Use NVENCC64 command line to re-encode BL, keeping HDR (and HDR10+ metadata if included).
3. Use TSmuxer to create a new copy of the original m2ts file swapping out the original BL for my encoded BL.
4. Open the UHD folder in MakeMKV to create a MKV file with HDR/DV (and HDR10+ if included)


Now, I'm also unsure how well (or if at all) these files play as I currently don't have a TV with Dolby Vision. Hopefully soon!!

This works well thank you. However, I've also been able to extract EL.hevc using ffmpeg from the largest m2ts file and then merge it with a re-encoded BL using yusesope's MUX.bat (beta 4). But this actually produces a larger file size in all cases than if using your TSmuxer/MakeMKV method. Do you know why this would be the case and are we losing FEL in the process somewhere?

Got it. Thanks!

Now, if I want to reduce the overall filesize from ripped from disc size of 48+ GB, can I send the whole MKV file through Handbrake or will I have to separate the layers of the video track and only run the BL through so as to not ruin anything for DV?

I doubt Handbrake can be used for UHD as I don't think it can do HDR. In any case, the layers must be separated as only the BL can be re-encoded.

What I do is:

1. Rip to folder using MakeMKV.
2. Use NVENCC64 command line to re-encode BL, keeping HDR (and HDR10+ metadata if included).
3. Use TSmuxer to create a new copy of the original m2ts file swapping out the original BL for my encoded BL.
4. Open the UHD folder in MakeMKV to create a MKV file with HDR/DV (and HDR10+ if included)


Now, I'm also unsure how well (or if at all) these files play as I currently don't have a TV with Dolby Vision. Hopefully soon!!

This works well thank you. However, I've also been able to extract EL.hevc using ffmpeg from the largest m2ts file and then merge it with a re-encoded BL using yusesope's MUX.bat (beta 4). But this actually produces a larger file size in all cases than if using your TSmuxer/MakeMKV method. Do you know why this would be the case and are we losing FEL in the process somewhere?

Don't know.
