Я использую FFMPEG для преобразования файла VTT в SRT. Но выходной файл имеет проблему с перекрытием. Мне нужна помощь, чтобы исправить эту проблему

WEBVTT
Kind: captions
Language: en
Style:
::cue(c.colorCCCCCC) { color: rgb(204,204,204);
 }
::cue(c.colorE5E5E5) { color: rgb(229,229,229);
 }

ffmpeg может сделать это во время конвертации с опцией -fix_sub_duration .

от man ffmpeg:

   -fix_sub_duration
       Fix subtitles durations. For each subtitle, wait for the next
       packet in the same stream and adjust the duration of the first to
       avoid overlap. This is necessary with some subtitles codecs,
       especially DVB subtitles, because the duration in the original
       packet is only a rough estimate and the end is actually marked by
       an empty subtitle frame. Failing to use this option when necessary
       can result in exaggerated durations or muxing failures due to non-
       monotonic timestamps.

   Note that this option will delay the output of all data until the
   next subtitle packet is decoded: it may increase memory consumption
   and latency a lot.
