This is a known bug. https://trac.ffmpeg.org/ticket/667

so I just want a split file

[ted423]

so I just want a split file

Use ffmpeg for that ffmpeg -i file.ts -c copy -vn -sn -map 0:a:0 mfile.mp4 (or thd or ts)

I need time to do some testing and come up with a concrete response. Most of the time I read mpls directly. In some cases, will need merge multiple m2ts, eac3to and mkvtoolnix will cause some errors

[ted423]

merge multiple m2ts,

Segmented m2ts has some segments in TrueHD that should be removed anyway. That can be done with https://github.com/domyd/mlp

thanks a lot, I will try later

[jcdr428]

@ValZapod double major sync units should be found only after last access units, which is not the case anymore with domyd. tsMuxer THD might be 100ms out of sync in very, very rare cases similar to Monsters University containing 100+ m2ts segments, but at least the THD stream is DD compliant.

[jcdr428]

@ValZapod can you please open a new issue and clarify/detail what is broken/what needs to be fixed ?

[justdan96]

It isn't clear what the issue with tsMuxer is - can someone please clarify?

ffmpeg can't decode turehd with ac3. So I want tsMuxer can extract it to two file. ValZapod Try to give me some other solutions.

but some BD has multi m2ts, useac3to and mkvtoolnix make some sync issue like this https://github.com/justdan96/tsMuxer/issues/262

I have not tested tsMuxer on Truehd whether there are similar problems, and these discussions are out of topic
