Uh, no, now those subtitles are encoded onto the video and it's almost
impossible to get them out again. Certainly those aren't text subtitles
anymore.
By embedded subs I mean the separate subtitle tracks but in the same
container as the file, selectable via -sid.
(and I can't resist saying that "try" becomes "tried", not "tryed" :-) )

While that is true, I'd expect the simplest source code couldn't help
much if you aren't aware of the different subtitle formats and what it
means what you can reasonably do with them and what not...
Anyway, the code is really new and there are quite a few issues with it
still (I just fixed a whole bunch), just try again with the external
subtitle and tell me if there are still issues.
