Summary0000542: Sync issues when demuxing UHD BluRays with seamless branching.
Descriptionwhen demuxing the UHDs of Straight Outta Compton Unrated (2015), Coco (2017), Bad Santa 2 Unrated (2016), Close Encounters of the Third Kind (1977), Independence Day (1996), and many other UHDs, Audio and subtitles will get out of sync. eac3to "2ndpass/fixing" will make it go out of sync. sometimes the audio and subtitles will get out of sync even when using "-no2ndpass". for some reason -no2ndpass doesn't apply to subtitles. I've been using MakeMKV in the meantime. No sync issues with that program.
Steps To ReproduceCoco (2017)
just try demuxing the 800.mpls playlist. Atmos won't be able to get "fixed", but the ac3 track will. when you merge the streams with mkvmerge, you can hear atmos is in sync, but the ac3 track isn't. subtitles are also out of sync.

Straight Outta Compton (2015)
I've been trying to demux it with no2ndpass and 2ndpass. both times audio and subtitles are out of sync.

Additional Informationeac3to is useless for UHD BluRays that have seamless branching. eac3to can demux UHD BluRay Playlists with just one m2ts file completely fine no sync issues.
