things to consider:

  • how to get ffmpeg to give us subtitles that started before the current timestamp but are still onscreen now
  • make sure that the subtitles are already ass or srt
  • strip out xml tags?

ok yeah i don't think ffmpeg is gonna be cooperative, what we should probably do is just extract the whole subtitle track as an srt, and then use the srtlib crate to parse it, and just iterate through to find every subtitle that starts before our timestamp and ends after our timestamp.
