Android-再次解读萤石云视频

作者:互联网

### 前言 我之前写过一篇萤石云的集成文章,很多人问我有没有demo, 今天我再次总结一下, 并加个些功能。 - 集成步骤 - 视频预览播放 - 视频放大缩小 - 视频的质量切换 - 截图 - 视频加载细节 之前的文章大家可以看下面的链接: https://mp.weixin.qq.com/s/V4F2_bkY8QFN167KY9gSDg 先看效果图: ![](https://www.icode9.com/i/l/?n=18&i=blog/1312938/201909/1312938-20190906095754634-787402893.gif) ### 集成步骤 ###### 1.安装SDK ``` dependencies { compile 'com.hikvision.ezviz:ezviz-sdk:4.8.6.2' } ``` ###### 2.配置工程 (1).权限配置 在 AndroidMainfest.xml 文件中添加: ``` //网络权限 //存储权限 //wifi 状态权限 //热点配网扫描wifi需要使用 ``` (2).配置build.gradle ``` defaultConfig { ... ndk { abiFilters "armeabi-v7a"//只支持v7a } } sourceSets { main { jniLibs.srcDirs = ['libs'] } } ``` (3).配置 AndroidManifest.xml 添加如下activity定义,用于sdk中间页显示,包含登录、开通云存储等。 ``` ``` 具体可以参考官方集成网站 https://open.ys7.com/doc/zh/book/4.x/android-sdk.html ### 视频预览播放 播放与之前版本不同,**加入设备的验证码** ``` mEZPlayer.setPlayVerifyCode("验证码"); ``` (1).SDK初始化(在application中初始化) ``` /** * sdk日志开关,正式发布需要去掉 */ EZOpenSDK.showSDKLog(true); /** * 设置是否支持P2P取流,详见api */ EZOpenSDK.enableP2P(false); /** * APP_KEY请替换成自己申请的 */ EZOpenSDK.initLib(this, APP_KEY); ``` (2).播放主要代码 设置token ``` EZOpenSDK.getInstance().setAccessToken("你的token"); ``` **实现代码:** 布局主要控件是SurfaceView,SurfaceView的用法大家应该都知道吧,主要实现了implements SurfaceHolder.Callback接口,声明SurfaceView 对象,并实方法,代码如下: ``` private SurfaceView mRealPlaySv = null; private SurfaceHolder mRealPlaySh = null; ``` ``` mRealPlaySh = mRealPlaySv.getHolder(); mRealPlaySh.addCallback(VideoActivity.this); ``` ``` Override public void surfaceCreated(SurfaceHolder holder) { if (mEZPlayer != null) { mEZPlayer.setSurfaceHold(holder); } else { } mRealPlaySh = holder; } @Override public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { } @Override public void surfaceDestroyed(SurfaceHolder holder) { if (mEZPlayer != null) { mEZPlayer.setSurfaceHold(null); } mRealPlaySh = null; } ``` ``` ``` 实现Handler.Callback,来监听播放结果回调: ``` @Override public boolean handleMessage(Message msg) { switch (msg.what){ } return false; } ``` 配置: ``` //用来存储萤石云的播放质量、序列号 mCameraInfo=new EZCameraInfo(); // 2-高清,1-标清,0-流畅 mCameraInfo.setVideoLevel(2); //序列号 mCameraInfo.setDeviceSerial("C86398971"); mCameraInfo.setCameraNo(1); ``` 开始播放: ``` private void startRealPlay() { mEZPlayer = YourApplication.getOpenSDK().createPlayer(mCameraInfo.getDeviceSerial(), mCameraInfo.getCameraNo()); mEZPlayer.setPlayVerifyCode(mVerificationCode); mEZPlayer.setHandler(mHandler); mEZPlayer.setSurfaceHold(mRealPlaySh); mEZPlayer.startRealPlay(); tvPlay.setEnabled(true); } ``` ### **视频放大,手势放大功能** 在播放成功的回调里加上 setRealPlaySvLayout();方法,方法的代码如下: ``` private void setRealPlaySvLayout() throws InnerException, PlaySDKException { DisplayMetrics dm = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(dm); int whdth = dm.widthPixels; int height = dm.heightPixels; mRealPlayTouchListener.setSacaleRect(Constant.MAX_SCALE, 0, 0, whdth, height); setPlayScaleUI(1, null, null); } ``` ``` private void setPlayScaleUI(float scale, CustomRect oRect, CustomRect curRect) { if (scale == 1) { try { if (mEZPlayer != null) { mEZPlayer.setDisplayRegion(false, null, null); } } catch (BaseException e) { // TODO Auto-generated catch block e.printStackTrace(); } } else { if (mPlayScale == scale) { try { if (mEZPlayer != null) { mEZPlayer.setDisplayRegion(true, oRect, curRect); } } catch (BaseException e) { // TODO Auto-generated catch block e.printStackTrace(); } return; } try { if (mEZPlayer != null) { mEZPlayer.setDisplayRegion(true, oRect, curRect); } } catch (BaseException e) { // TODO Auto-generated catch block e.printStackTrace(); } } mPlayScale = scale; } ``` ### 视频质量切换 效果图: ![](https://www.icode9.com/i/l/?n=18&i=blog/1312938/201909/1312938-20190906095808850-1209709960.gif) 核心方法 ``` // 2-高清,1-标清,0-流畅 mCameraInfo.setVideoLevel ``` 切换画质 ``` /** * 码流配置 清晰度 2-高清,1-标清,0-流畅 * * @see * @since V2.0 */ private void setQualityMode(final EZConstants.EZVideoLevel mode) { if (mEZPlayer != null) { mWaitDialog.setWaitText("正在设置画面质量…"); mWaitDialog.show(); Thread thr = new Thread(new Runnable() { @Override public void run() { try { // need to modify by yudan at 08-11 APP.getOpenSDK().setVideoLevel(mCameraInfo.getDeviceSerial(), mCameraInfo.getCameraNo(), mode.getVideoLevel()); mCurrentQulityMode = mode; Message msg = Message.obtain(); msg.what = MSG_SET_VEDIOMODE_SUCCESS; mHandler.sendMessage(msg); } catch (BaseException e) { mCurrentQulityMode = EZConstants.EZVideoLevel.VIDEO_LEVEL_FLUNET; e.printStackTrace(); Message msg = Message.obtain(); msg.what = MSG_SET_VEDIOMODE_FAIL; mHandler.sendMessage(msg); } } }) { }; thr.start(); } } ``` 切换画质结果: ``` //切换画质成功 case EZConstants.EZRealPlayConstants.MSG_SET_VEDIOMODE_SUCCESS: handleSetVedioModeSuccess(); break; //切换画质失败 case EZConstants.EZRealPlayConstants.MSG_SET_VEDIOMODE_FAIL: handleSetVedioModeFail(msg.arg1); break; ``` ### 声音与截图 1.声音 核心方法: ``` mLocalInfo.setSoundOpen(false); ``` 2.截图 核心方法: ``` mEZPlayer.capturePicture() ``` 需要**源码**的朋友可以加我的微信:lengquele5311 ![](https://www.icode9.com/i/l/?n=18&i=blog/1312938/201909/1312938-20190906095809708-1381148883.jpg) 大家可以关注我的微信公众号:「秦子帅」一个有质量、有态度的公众号! ![公众号](https://www.icode9.com/i/l/?n=18&i=blog/1312938/201909/1312938-20190906095809875-938818605.jpg)
