Comment (by ubitux):
You need to do that in two steps currently. libavfilter has no visibility
on your seek.
{{{
ffmpeg -ss 30 -i f.srt f2.srt
ffmpeg ... -vf subtitles=f2.srt ...
}}}
Alternatively, we could add a seek parameter to the filter. The best
solution is obviously to support proper subtitles filtering, but this is
another long standing issue, not easy to deal with, and which require
large changes.
