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.

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.
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?

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!

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.

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.

Thank you as I suspected,
Aquaman,I taught that was Mel
I guess it creating a fel with the hdr10 would only be beneficial if the hdr 10 uhd version has imax scenes but no dv.

Im not sure, the EL is 2093 kbps.
There are not really a lot of Bluray IMAX DV.
I hope Top Gun 2 will come out as IMAX DV.

Maybe we should open another topic to summarize all the points discussed here. The first post is already too outdated.

Hi, RESET_9999. When will the AAC be?
I checked again last night and AAC 7.1 is played as 5.1 on LG TVs. So I won't add support for that....
But tell me exactly the ffmpeg command line you want me to use and I'll change the EC3 workflow to AAC and make a special version of my script just for you.

Someone should tell the mp4box devs that it cannot mux coreless 7.1 EC3 track properly. The audio stutter and it's probably exactly the same problem tsMuxer had before the latest version.
Then I could add proper 7.1 audio support to the mp4 workflows.
@jcdr428.... there was a mistake, the frame length must be calculated from the independent stream only -the frame length from the dependent substream must be discarded.
Please check tomorrow's release.

The 2mbps or less layers are usually MEL.
