I am trying to create .ts backups of these while maintaining Dolby Vision and TrueHD/Atmos.
Using the steps in https://www.makemkv.com/forum/viewtopic ... start=1305
I am not able to maintain TrueHD/Atmos. The audio track defaults to AC3 and does not playback in lossless Atmos.
Dolby Vision is maintained. Atmos is also maintained when I rip an MKV from the disc. I can playback the MKV using Plex on my SHIELD Pro without issues. I want .ts files for compatibility with other devices.
Has anyone else tried this and had success?
You can see the differences in the output files from tsmuxer after creating the .ts and the mkv created with makemkv (screenshot 101 is tsmuxer, screenshot 102 is the mkv created with makemkv). The audio track is taken from full disc backup. I also tried using eac3to to rip the audio track from the makemkv and remux it using tsmuxer. The results have been the same no matter what I try.
Have you tried selecting a different audio track with your TS files in Plex? The AC3 core will be defaulted to, yes, but you should be able to select the TrueHD track as well. It's obviously in there according to the mediainfo.
There is only one audio track in the file.
I did do some more testing with tsmuxer, eac3to, etc. I also did another full backup of the disc. I noticed that mediainfo shows the same exact info for the audio track of the stream from the full disc backup.
This is the mediainfo output for the file from the disc backup:
