[MEncoder-users] Mencoder forced subtitles with vobsubout

[Shaun Simpson]

Hi,

I would like to know how to create a subtitle .idx and .sub that
contains "forced" subtitles.

I have tried:

mencoder dvdnav://1 -slang en -forcedsubsonly -vobsubout forced-subs
-ovc frameno -nosound -o /dev/null

This gives a file that contains all the subtitles:

# VobSub index file, v7 (do not modify this line!)
#

Vobsub
#
size: 720x576
# ON: displays only forced subtitles, OFF: shows everything
forced subs: OFF

# Language index in use
langidx: 0

id: xx, index: 0
timestamp: 00:00:20:199, filepos: 000000000
timestamp: 00:00:23:519, filepos: 000000800
timestamp: 00:00:28:040, filepos: 000001000
timestamp: 00:00:29:679, filepos: 000001800
...

Is it possible to get a .idx/.sub file that only contains forced subs?

I am using:
Ubuntu 9.10
Mencoder 1.0 RC3 SVN 2009/04/26

Thank you for you time,
Shaun
