SSA sub unsync / resync

[Duke]

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 N-51205-gac9b056
