25fps to 24fps sudden fail !

[ToiletDuck]

Subtitles timings can actually cause this  Dodgy ? 

Yes, subtitle and chapter settings can both cause that you see a black screen while the video already finished.
Basically any stream can extend the play length.

Without details, I can't say anything more specific.

Let me ease your mind .. it's not caused by subs or any other content.. 
It's caused by *DING DING* → the type of container i have used 

Yep, it looks like your old friend "tsmux/m2ts" is throwing a spanner in the works again... 
using other containers : mkv, mp4... seems to fix this .. 

Though the framerate wos flagged right of the messed up media file accordingly to mediainfo among others ..

So and again, something isn't working right about TSmux and Hybrid..  

Merging files containing atmos tracks results in crashes using tsmux, now this again also caused by TSMUX... Can't be coincidence if you ask me..

  
But who am i...  iam only speaking the wrong thing at the wrong time... isn't it 

cheers,
