The above source code pushes the subtitles for the first video, and after that, the track information is modified and reflected in javascript at the [0]th.
The normal operation of the first subtitle has been confirmed. When the second video was played, it was also confirmed that the label was changed normally.
However, there is a problem that the subtitles of the second video are not output normally, and the first subtitles are output.
Rather than modifying options after player init, use removeRemoteTextTrack() and addRemoteTextTrack() to replace the tracks.
