[MPlayer-users] Only dump forced subtitles.

[Nicholas Robbins]

I would like to only dump subtitle entries that are marked as 'forced' from a non-forced subtitle stream in a mkv.

I tried using the -forcedsubsonly but it doesn't seem to make a difference. The files with and without it are exactly the same, even though I know that most of the subs are not actually forced. 

My command:

mencoder IN.mkv  -vobsubout test -vobsuboutindex 0 -sid 0  -nosound -ovc frameno -o /dev/null -msglevel vobsub=9 -forcedsubsonly


Am I doing this right?
