[MPlayer-users] how to extract tx3g subtitle from .mp4 file

[luis jure]

hello list,

i have an .mp4 file with subtitles mov_text (tx3g) format:

[lavf] stream 3: subtitle (mov_text), -sid 0, -slang deu

the subtitles play fine, but i need to dump them to a file and -dumpsrtsub
didn't work. 

i don't know if the problem is the subtitle format, the mp4 container, or
this file in particular (sorry, i know virtually nothing about tx3g
subtitles or the mp4 container in general).

is it possible to do in mplayer? any other suggestions would be also
welcome.


TIA,


lj
