Thanks for suggestion. I rarely need this but I've used mplayer
succesfully for timing subtitle files. The usual pattern is:
mplayer film.mkv -dumpmicrodvdsub [...]
mplayer film.mkv -sub dumpsub.sub -subdelay X -subfps Y
When I have correct values for X and Y I do:
mplayer film.mkv -sub dumpsub.sub -subdelay -X -subfps Y -dumpsrtsub
So it seems I need to change the sign of subdelay value X before I run
-dumpsrtsub. It's OK but I don't remember having required to do that
before. Maybe I remember wrong.
