 Summary of the bug:
 When I try to burn subtitles in the video, everything is fine, except when
 I try seeking. The subtitles are added again from the first second, not
 from 30 minute. I think that when I seek the movie, the subtitles must be
 seeked too.

 How to reproduce:
 {{{
 C:\ffmpeg>ffmpeg -ss 00:30:00 -i f.avi -vf subtitles=f.srt -c:a vorbis
 -strict -2 -c:v libx264 -preset ultrafast fout.mp4
 }}}
