Dolby Vision now possible through MP4 Mux.

we tested on appletv and LPCM audio didn't work when using it IIRC so that's why you see HDR10 two times when choosing fake p5

[johnjon94]

The fake P5 doesn't seem to be working properly. It set a very odd FPS resulting in this crazy length

maybe an appleTV web-dl ? i know the old mp4muxer also had issue muxing those file because they dont have FPS bistream information.
with the sample files i used, there is no problem:

Can you point me to the place in the code where the final mp4box settings are for the Apple TV mux with AC3? It will work if I manually set the fps with mp4box, I can't seem to figure out why its pulling the incorrect fps from the stream.

thanks. next version will set a fps all the time regardless of if the input is appleTV web-dl or not

only support 23.976/24/25 fps for now.. will add more in the official 1.6.1

This version seems to work great at detecting the correct FPS. I can see right now that its displaying the correct 24000/1001 when importing the HEVC file. However for the subtitles it isn't setting any language for them, and the first subtitle which is forced isn't displaying the Forced tag.

yes I know. it is on my todo list since @sw5163 told me about it..
I just dont care much about the mp4 workflows because i dont use them. TS container is much better than mp4.

[johnjon94]

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)
