Unity录屏实现（三）

继续填上次的坑，,本文只是转载，偶尔看见一博客说 5.1有录屏api，好吧，还是看代码吧：

Android代码：

package cn.net.xuefei.unityrec;
import java.io.File;
import java.io.IOException;
import com.unity3d.player.UnityPlayerActivity;
import android.Manifest;
import android.content.ContentValues;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.hardware.display.DisplayManager;
import android.hardware.display.VirtualDisplay;
import android.media.MediaRecorder;
import android.media.projection.MediaProjection;
import android.media.projection.MediaProjectionManager;
import android.os.Bundle;
import android.os.Environment;
import android.os.Handler;
import android.os.Message;
import android.provider.MediaStore;
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;
import android.util.DisplayMetrics;
import android.widget.Toast;public class MainActivity extends UnityPlayerActivity {private static final int RECORD_REQUEST_CODE = 101;private static final int STORAGE_REQUEST_CODE = 102;private static final int AUDIO_REQUEST_CODE = 103;private static final int SHOW = 1;private static final int CANCEL = 2;private boolean isRecording;public static Context currentActivity;private MediaProjectionManager mediaProjectionManager;private Handler mHandler = new Handler() {@Overridepublic void handleMessage(Message msg) {super.handleMessage(msg);switch (msg.what) {case SHOW:if (isRecording) {Toast.makeText(MainActivity.this, "录制已开始", Toast.LENGTH_SHORT).show();} else {startScreenCapture();isRecording = true;}break;case CANCEL:if (isRecording) {mediaRecorder.stop();mediaRecorder.reset();mediaProjection.stop();virtualDisplay.release();isRecording = false;insertVideoToMediaStore(getSaveDirectory() + videoName);Toast.makeText(MainActivity.this, "录制结束", Toast.LENGTH_SHORT).show();} else {Toast.makeText(MainActivity.this, "没有开始录制", Toast.LENGTH_SHORT).show();}break;}}};private MediaProjection mediaProjection;private MediaRecorder mediaRecorder;private VirtualDisplay virtualDisplay;/*** 屏幕的宽度*/private int screenWidth;/*** 屏幕的高度*/private int screenHeight;/*** 屏幕的像素*/private int screenDpi;private DisplayMetrics metrics;/*** 保存在相册视频的名字*/private String videoName;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);mediaRecorder = new MediaRecorder();metrics = new DisplayMetrics();getWindowManager().getDefaultDisplay().getMetrics(metrics);/*** 动态注册权限*/if (ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {ActivityCompat.requestPermissions(this, new String[] { Manifest.permission.WRITE_EXTERNAL_STORAGE },STORAGE_REQUEST_CODE);}if (ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.RECORD_AUDIO) != PackageManager.PERMISSION_GRANTED) {ActivityCompat.requestPermissions(this, new String[] { Manifest.permission.RECORD_AUDIO },AUDIO_REQUEST_CODE);}currentActivity = this;//mUnityPlayer.requestFocus();}/*** unity调用的方法，需要用一个handler进行处理实现功能，直接无法实现。*/public void stopRecordin() {mHandler.sendEmptyMessage(CANCEL);}/*** unity调用的方法，需要用一个handler进行处理实现功能，直接无法实现。*/public void startRecording() {mHandler.sendEmptyMessage(SHOW);}private void startScreenCapture() {mediaProjectionManager = (MediaProjectionManager) getSystemService(MEDIA_PROJECTION_SERVICE);Intent captureIntent = mediaProjectionManager.createScreenCaptureIntent();startActivityForResult(captureIntent, RECORD_REQUEST_CODE);}public void setConfig(int screenWidth, int screenHeight, int screenDpi) {this.screenWidth = screenWidth;this.screenHeight = screenHeight;this.screenDpi = screenDpi;}protected void onActivityResult(int requestCode, int resultCode, Intent data) {if (requestCode == RECORD_REQUEST_CODE && resultCode == RESULT_OK) {mediaProjection = mediaProjectionManager.getMediaProjection(resultCode, data);setConfig(metrics.widthPixels, metrics.heightPixels, metrics.densityDpi);startRecord();Toast.makeText(this, "开始录制", Toast.LENGTH_SHORT).show();}}public boolean startRecord() {initRecorder();createVirtualDisplay();mediaRecorder.start();return true;}private void createVirtualDisplay() {virtualDisplay = mediaProjection.createVirtualDisplay("MainScreen", screenWidth, screenHeight, screenDpi,DisplayManager.VIRTUAL_DISPLAY_FLAG_AUTO_MIRROR, mediaRecorder.getSurface(), null, null);}private void initRecorder() {mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);mediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE);mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);videoName = System.currentTimeMillis() + ".mp4";mediaRecorder.setOutputFile(getSaveDirectory() + videoName);mediaRecorder.setVideoSize(screenWidth, screenHeight);mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);mediaRecorder.setVideoEncodingBitRate(5 * 1024 * 1024);mediaRecorder.setVideoFrameRate(30);try {mediaRecorder.prepare();} catch (IOException e) {e.printStackTrace();}}public String getSaveDirectory() {if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {String screenRecordPath = Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator+ "DCIM" + File.separator + "Camera" + File.separator;return screenRecordPath;} else {return null;}}public void insertVideoToMediaStore(String filePath) {ContentValues values = new ContentValues();values.put(MediaStore.MediaColumns.DATA, filePath);// video/*values.put(MediaStore.MediaColumns.MIME_TYPE, "video/mp4");getContentResolver().insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, values);}/*** 打开相册，** @return*/public void openAlbum() {Intent intent = new Intent(Intent.ACTION_PICK);startActivity(intent);}
}

Unity代码：

using UnityEngine;
using System.Collections;public class UnityRec : MonoBehaviour
{ // Use this for initializationvoid Start(){}// Update is called once per framevoid Update(){}void OnGUI(){if (GUI.Button(new Rect(0, 0, 300, 300), "开始录屏")){
#if UNITY_ANDROIDAndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");jo.Call("startRecording");
#elif UNITY_IPHONE#endif}if (GUI.Button(new Rect(0, 300, 300, 300), "停止录屏")){
# if UNITY_ANDROIDAndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");jo.Call("stopRecordin");
#elif UNITY_IPHONE#endif}}
}

我只是在Android 6.0的机器上测试了一下，其他版本，布吉岛哇……
