Comment (by ghospich):

 Implementing option 'ss' in subtitles filter would be decent workaround
 too. Here is citation from another issue about this (duplicate #3852)
 > So, maybe add option 'ss' to filter ​http://ffmpeg.org/ffmpeg-
 filters.html#subtitles-1 with same function as -ss in ffmpeg itself? This
 would be simple and convenient workaround.
 > The ss option would specify from what point ffmpeg should start
 subtitles, explicitly.
 >
 > There is already such option in ffmpeg itself, so in 'subtitles' it
 wouldn't be a foreign.
 > And with this option it would be finally possible to burn subtitles in
 fast seek mode.
