            mediaPlayer = new MediaPlayer();
            mediaPlayer.setDataSource("http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4");
            mediaPlayer.prepare();
            mediaPlayer.start();

            // 소리만 나오는 플레이어 방법 2
            Uri uri = Uri.parse("http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4");
            mediaPlayer2 = MediaPlayer.create(this, uri);
            mediaPlayer2.start();

            // 소리만 나오는 플레이어 방법 3
            mediaPlayer3 = MediaPlayer.create(this, R.raw.sample);
            mediaPlayer3.start();

        } catch (Exception e) {
            e.printStackTrace();
        }

    }

}

실행하면 소리만 재생된다.
