Use case

Right now it is not possible to use the video_player package a set a delay to a caption file. (if the caption is not in sync with the sound)

Proposal

https://pub.dev/packages/flutter_vlc_player
uses:

  /// [delay] - the amount of time in milliseconds which vlc subtitle should be delayed. (both positive & negative value appliable)
  Future<void> setSpuDelay(int delay);

I think for this package we should use something like this:

  void setCaptionOffset(Duration offset);
