Fixed version (ground truth):

    mp.start();
    mp.seekTo(mCurrentPosition);
    if (mp.getDuration() > 1000) {
      mVideoProgressBar.setVisibility(View.VISIBLE);
      mVideoProgressBar.setProgress(mCurrentPosition);
      mVideoProgressBar.setMax(mp.getDuration());
      mVideoProgressBarSubscription=Observable.interval(10,TimeUnit.MILLISECONDS).filter(__ -> mMediaPlayerPrepared).map(__ -> mp.getCurrentPosition()).subscribe(progress -> mVideoProgressBar.setProgress(progress),throwable -> {
