                             val override = TrackSelectionOverride(group.mediaTrackGroup, i)
                             player?.let { player ->
                                 val parameters =
                                       player.trackSelectionParameters
                                      .buildUpon()
                                      .addOverride(override)
                                      .build()
                                  player.trackSelectionParameters = parameters
                                     }
                                }
                            }
                        }
                    }

i am able to see the tracks, but sometimes captions are not matching with audio.video, its lagging
