 Im trying to sync ssa/ass subtitles for burnin streaming but whenever the
 stream changes time, ie -ss 60, the ass will start back at beginning
 instead of seeking to position. -ss after input results in subtitle
 overlap of beginning and current time.

 How to reproduce:
 {{{
 % ffmpeg -ss 60 -i abc.mkv -vf ass=abc.ass -y abc.mp4


 ffmpeg version
 ffmpeg -ss 60 -i abc.mkv -vf ass=abc.ass -y abc.mp4ffmpeg version
