I think taifun player or exoplayer doesn’t have buffering service that’s why to seek to the position always needs a time as well. In my honest opinion, an exoplayer or Taifun doesn’t work properly if your music is very long. It is quite good for the music of 5 to 10 minutes. I request every @ExtensionDevelopers to make a music player that can work in the background as well as it has buffering service.
