3 years ago Can you confirm if it does not work if you isolate just one audio track of Dolby TrueHD with Dolby Atmos?

Yes then it's the same case. git rev: 2aa293b5136321e2d88cd45bd2a8e09499d4a69a

01:59:51.434 : en:Chapter 16I just open up makemkv 1.16.4, I open my John Wick disc and select only the main video (which is Dolby Vision) and the TrueHD audio track. Here's the first 50MB of the file: https://mega.nz/file/b4EAlRhZ#eKmTuE5MjfSAzgrUKd8PxRCoPJtISUC1foEg7eoBxRA
When I create a TS file with TSMuxer from the same disc, I only have to select the TrueHD track and there will automatically be a second "core" AC3 5.1 track as well when I try to play it in Plex or Emby.
makemkv somehow rips these two apart from each other as two different pids inside the MKV, perhaps TSMuxer is expecting the trueHD track to have some embedded core AC3 thing as well..
Just thinking out loud.

3 years ago See #256 and #270 . @justdan96 I will work on muxing / demuxing pure TrueHD when version 2.7 is out.

3 years ago Hi @jcdr428 That would be very nice. Then perhaps we could have an option to split the core_ac3 and TrueHD in the GUI to have them muxed as two separate tracks/pids.

3 years ago Seems it's a compatibility issue with the MKV container and a stream of TrueHD within the AC3 core. If such stream is to be imported into somekind of MKV or FFMPEG muxers, they just won't take it as a whole stream but two separate streams (a.k.a. a stream of TrueHD only and another of AC3 core) instead.
What I'd like to see more is, while importing an AC3 stream and a TrueHD-only stream, there's an option to combine these two stream together as one whole AC3 stream, which is supposed to be recognized by TSMuxer (within versions before). @jcdr428 Although I see a methodology in #256 , by adding a null AC3 as core (in lowest bitrate possible as 32kbps), it will be better to have a dedicate AC3 import instead, along with the TrueHD stream into the job.

Hi there,
I used makemkv to remux the bluray disc of John Wick 3 (with dolby vision) to mkv. I have chosen to only retain the AC3 5.1 and TrueHD/Atmos tracks. The mediainfo shows like:
However when I try to import this into the tsmuxer gui, it says:
Only the video and first AC3 audio track are there. I'd like to remux both audio tracks into a .TS container (AC3 5.1 being the first one).
