I want to modify the position of the subtitles

[Ambercssa]

const arr = {
src: 'http://qixuebao-test.oss-cn-hangzhou.aliyuncs.com/0001/ZP/WT/MDPLT11ZVNI03H.vtt'
kind: 'subtitles',
srclang: 'en',
label: 'english',
mode: 'showing',
default : 'true'
}
this.player.addRemoteTextTrack(arr)

@Ambercssa would you like to offset the subtitles from the top or bottom of the box? The offset is calculated from the top of the box, see https://w3c.github.io/webvtt/#webvtt-cue-line

When testing your subtitle file, everything seems to work as expected. You can try changing the position of the subtitles to see if there is any change:

Array.from(player.textTracks())
  .find(track => track.mode ==='showing')
  .cues_.forEach(cue => cue.line = Math.floor(Math.random() * 100))
