   I was defined a UObject to control Mediaplayer. and it will NewObject<UMediaplayer> at construct method.listen sm. delegates.
  It can work perfectly in version 5.2.  But when I copy to 5.3.  identified multiple issues:

  1. Use UMediaPlayer::GetTime() end of started open file , FTimespan is not start with 0, And When I Call this function at OnEndReached callback function. this value not equals with Duration. This issues make me can’t create UMG to show playing progress bar.

  2. When i use Reopen() and Play at OnMediaOpened callback function ,or Seeking() function. player will not play continue , I was try to Pause() and Play() or reopen and play .It not work.
