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.
