import android.os.Bundle
import android.view.SurfaceHolder

var mediaPlayer = MediaPlayer()
mediaPlayer.setDataSource("http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4")
mediaPlayer.prepare()
mediaPlayer.start()
// 소리만 들리는 플레이어 방법 2
var uri = Uri.parse("http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4")
var mediaPlayer2 = MediaPlayer.create(this, uri)
mediaPlayer2.start()
// 소리만 들리는 플레이어 방법 3
var mediaPlayer3 = MediaPlayer.create(this, R.raw.sample)
mediaPlayer3.start()

}실행하면 소리만 재생된다.
