what is that supposed to mean?

Excuse me, I _am_ a user*. I do not work on the ffmpeg code although 
after a few decades of writing code, sometimes in 'c', I can generally 
read it.

*everyone using a computer is a 'user' of something, some have a better 
understanding of how the systems work.

No, you're supposed to use the tools available to find information that 
may lead you to an understanding. Demanding answers with no apparent 
effort to find them yourself comes across as lazy and inconsiderate. 
Simply searching 'ffmpeg "sost"' turns up multiple hits that indicate 
that subtitles are involved; they may not answer the question directly, 
but they point that direction. So will searching "dvdsub format". That 
and #0.2 is another good indicator that stream 0.2, which happens to be 
subtitles, is a probably source of the error.


If you're going to use a complex & powerful tool, it behooves you to 
both know that it -is- powerful & complex and to treat it as such. If 
you don't want the hassle of it, use Handbrake or some other UI.


BTW, I also run windoze systems on-line but behind a firewall. This is 
not a problem. Heck, even behind a NAT router can give a good deal of 
protection, as can a decent virus scanner. (You can hobble your own 
setup, but don't complain about what it can't do.)

Later,
