Question

안드로이드 스튜디오 surfaceview를 이용한 스트리밍 캡처를 어떻게 하는지 궁금합니다.

스트리밍 영상 띄우는 다음과 같습니다. surfaceview로 화면 캡처를 하는 방법을 모르겠습니다.

package com.example.doyerim.mediaplayer;

import android.media.AudioManager;
import android.media.MediaPlayer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import java.io.IOException;

public class MainActivity extends AppCompatActivity implements SurfaceHolder.Callback, MediaPlayer.OnPreparedListener{
    private SurfaceView surfaceView;
    private MediaPlayer mediaPlayer;
    private SurfaceHolder surfaceHolder;
    //private static final String VIDEO_PATH="rtsp://192.168.1.50:8000/unicast";
    private static final String VIDEO_PATH="rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        surfaceView = (SurfaceView)findViewById(R.id.surfaceView);
        surfaceHolder = surfaceView.getHolder();
        surfaceHolder.addCallback(MainActivity.this);
    }

    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        mediaPlayer = new MediaPlayer();
        mediaPlayer.setDisplay(surfaceHolder);
        try{
            mediaPlayer.setDataSource(VIDEO_PATH);
            mediaPlayer.prepare();
            mediaPlayer.setOnPreparedListener(MainActivity.this);
            mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    protected void onPause(){
        super.onPause();
        releaseMediaplayer();
    }

    @Override
    protected void onDestroy(){
        super.onDestroy();
        releaseMediaplayer();
    }

    private void releaseMediaplayer(){
        if(mediaPlayer != null){
            mediaPlayer.release();
            mediaPlayer = null;
        }
    }

    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {

    }

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {

    }

    @Override
    public void onPrepared(MediaPlayer mp) {
        mediaPlayer.start();
    }



}
