Dolby Vision now possible through MP4 Mux.

I can't seem to get the fake P5 to play on Apple TV through Plex or directly. Doesn't seem to play on my computer either, just a black screen. I'm curious if there's just a small codec misconfiguration.

idk, i dont have any apple device... @ragico did all the testing when I did the apple workflows.
the only difference is the latest mp4box...
the cmd is the same i showed you before.

Code: Select all

"%mp4box2_path%" -add %BL%%mbox% -add %audio% -add %subtitles_path% -tmp %TEMP% "%output_path%%filename%_DoVi.sub.DD.mp4"

[RESET_9999]

are you sure its not your source again?

Original frame rate : 0.729 FPS

did you fix the fps bitstream with ffmpeg on that file? because i noticed that it cause some playback issue on my TV

[johnjon94]

Yeah I used bitstream filters with ffmpeg to fix the fps. These files play with no issue on my television normally and with any other player I've tried them on.

[johnjon94]

I've figured out the issue, its the demuxer that you're using. This is also why the framerate wasn't being pulled correctly, and I noticed for ATVP files that it wasn't demuxing with the accurate aspect ratio.

eac3to:

Code: Select all

 Track Importing HEVC - Width 3832 Height 1574

ffmpeg/tsmuxer:

Code: Select all

Track Importing HEVC - Width 3838 Height 1606

After demuxing with ffmpeg instead of eac3to then running the mp4box command the resulting file played with no issue and retained the aspect ratio and framerate. (And confirmed that Plex for Apple TV is triggering Dolby Vision and Atmos as well as the internal Plex app for LG C2)

well to be fair the issue is Apple's stupidity with their crappy encodes.
Anyway, I guess you'll have to do those over-cropped webdl manually because EAC3to is my number 1 demuxer since its the only one that allow me to demux all the tracks without knowing the streams ID.

can you input a resolution with mp4box?

[ragico]

Apple's native player or any player that "passthrough" that file to Apple's player core. Avoid using INFUSE.
I play them in "FILE" App directly SMB from my PC.

Pls can you explain where to find the "File" app?
It does not exist in the appstore.
Thank you

It's on the iOS appstore, the apple's official file manage app, im not sure if it's on ATV's store.

It's very hard to use and not recommended. Plex plays DV fine.
FE File Explorer is an alternate 3rd party file mangage app also plays DV.

Edit: FE File Explorer only plays DV on iOS, not ATV. See below discussion.

Or you can do what Manixx2020beyound did, if you have itunes or mac.

And u can upload that to your apple tv library

If anyone know how to import video through network directly into the "TV" app (the black background with white TV on it) on windows without having to use itunes, please let me know, very much appreciate!

Not on my ATV. It plays in sdr.
Only FileBrowseTV plays in DV

Maybe app on ATV is a little different from iOS.
I think there is a "hardware decode+" option in the FE File Explorer, it guarantees DV passthrough.
If it's only "hardware decode" or "software decode", it's not using the Apple's player core.

It's strange ATV doesn't have an official file management app though.

Unfortunately there is not the option "hardware decode+" nor any decode option in the ATV version.

Got an off topic question for u guys,(should know this but never really checked myself)
If a fel is present in an imax enhanced disc
Does a 1080p fel adjust aspect ratio to reflect the bl, im not in front a pc but more than likely it does.

Using ffmpeg & h265 can generate a fel & bl with dee simostainously I managed to compile h265, for dee was thinking of attempting ffmpeg
And using the imax web dl of Thor as base layer & using the hdr Thor version to create grain or fel layer from the hdr10 high bitrate. I would have to do 2 versions separate & mux
Sounds crazy but I think it’s possible we’ll not if the aspect ratio changes,also diff version might not be the same length.

[RESET_9999]

please try this. Now when the script detects that the input width is not 3840px or 1920px, it will use mkvextract to demux...
downside: it will only work if the input has only 1 video 1 audio (THD DTS or EC3/AC3) and will select only 1 sub. Wont work for dual audio input.
better than nothing I guess...

The only two movies im aware of that are IMAX and FEL are Mission.Impossible.Fallout.2018 and Aquaman.2018.
I have checked Fallout and the EL changes its aspect as BL.
