/**
* Created date: 2017/4/11
* Author: Leslie
* 使用海康SDK播放视频流的工具类.
* 前提：1->/libs/下放入：AudioEngineSDK.jar,HCNetSDK.jar,PlayerSDK.jar
* 2->/src/main/jniLibs/下放入：很多 .so 文件.
* 3->添加网络权限
* 目前只处理海康摄像头(室内枪型网络摄像机-【型号：DS-2CD5026EFWD】-【软件版本：V5.4.5_170222】)
* 但是该例子不仅限于这种型号的。
* 使用方法[由于要预览 2 路，所以很多静态方法，静态变量去掉了，调用流程也变化了]：
* 1.HikUtil.initSDK();
* 2.HikUtil hikUtil = new HikUtil();
* 2.hikUtil.initView(surfaceView);
* 3.hikUtil.setDeviceData("192.168.1.22",8000,"admin","eyecool2016");
* 4.hikUtil.loginDevice(mHandler,LOGIN_SUCCESS_CODE);
* 5.hikUtil.playOrStopStream();

小贴士
感谢您为本站写下的评论，您的评论对其它用户来说具有重要的参考价值，所以请认真填写。
- 类似“顶”、“沙发”之类没有营养的文字，对勤劳贡献的楼主来说是令人沮丧的反馈信息。
- 相信您也不想看到一排文字/表情墙，所以请不要反馈意义不大的重复字符，也请尽量不要纯表情的回复。
- 提问之前请再仔细看一遍楼主的说明，或许是您遗漏了。
- 请勿到处挖坑绊人、招贴广告。既占空间让人厌烦，又没人会搭理，于人于己都无利。
