前言
最近接到了一个让人窒息的活儿。简单来说需要做一个机器人的遥控器。需求就是用6818 Android系统做一个通过实体按键控制机器人同时要将机器人身上几个摄像头的数据显示到屏幕上的功能。这就有点窒息了。再此之前还没怎么深入接触过Android，于是又花了将近一个月的时间去学了一下子简单的Android开发。然后就风风火火的搞起来了。好像海康的文档真心不太多，搞起来还是有点麻烦的。
一、看海康的例程
移植海康的SDK的第一步当然是看他给出的事例了。

}
这个真的看得是有点头大啊。仔细分析的话我们可以发现有两条重要的线索。
（1）网络设备线
onCreate->CameraLogin->loginDevice->loginNormalDevice->NET_DVR_Login_V30
（2）设备播放线（这里采用流模式）
previewButton.setOnClickListener->startSinglePreview->getRealPlayerCbf->（回调部分，会被内部的库反复调用）processRealData->
Player.getInstance().setStreamOpenMode(playPort,iStreamMode)
Player.getInstance().openStream(playPort, pDataBuffer,iDataSize, 2 * 1024 * 1024)
play(playPort,surface.getHolder()))//播放部分的核心，将播放端口与surface控件，联系了起来
Player.getInstance().playSound(playPort)
Player.getInstance().playSound(playPort)
那么这两条线又是靠什么串起来的呢。也就是说播放库，怎么知道要播放的设备是啥呢，这就涉及到下面这个核心函数，将播放与网络设备初始化串联了起来
this.m_iPreviewHandle = HCNetSDK.getInstance().NET_DVR_RealPlay_V40(iLogId, netDVRPreviewInfo, realPlayCallBack);
m_iPreviewHandle：是播放部分的线索变量
iLogId： 是初始化部分的线索变量
这就是主要的部分了
二、重要的函数分析

连接方式：0- TCP 方式，1- UDP 方式，2- 多播方式，3- RTP 方式，4-RTP/RTSP，5-RSTP/HTTP
bBlocked
0- 非阻塞取流，1- 阻塞取流
bPassbackRecord
0-不启用录像回传，1-启用录像回传。ANR 断网补录功能，客户端和设备之间网络异常恢复之后自动将
前端数据同步过来，需要设备支持。
byPreviewMode
预览模式：0- 正常预览，1- 延迟预览
byProtoType
应用层取流协议：0- 私有协议，1- RTSP 协议
hHwnd
播放窗口的句柄，为 NULL 表示不解码显示
实时预览 NET_DVR_RealPlay_V40
函 数： public int NET_DVR_RealPlay_V40(int lUserID, NET_DVR_PREVIEWINFO previewInfo, RealPlayCallBack
CallBack)
参 数： [in] lUserID
[in] previewInfo
[in] CallBack
NET_DVR_Login_V30 的返回值
预览参数，包括码流类型、取流协议、通道号等，详见：
NET_DVR_PREVIEWINFO
码流数据回调函数
public interface RealPlayCallBack {public void fRealDataCallBack(int iRealHandle, int iDataType, byte[] pDataBuffer, int iDataSize);
}
[out] iRealHandle
[out] iDataType
[out] pDataBuffer
[out] iDataSize
当前的预览句柄
数据类型
存放数据的缓冲区指针
缓冲区大小
表 3.4 码流数据类型
dwDataType 宏定义 宏定义值 含义
NET_DVR_SYSHEAD 1 系统头数据
NET_DVR_STREAMDATA 2 流数据（包括复合流或音视频分开的视频流数据）
NET_DVR_AUDIOSTREAMDATA 3 音频数据
返回值： -1 表示失败，其他值作为 NET_DVR_StopRealPlay 等函数的句柄参数。接口返回失败请调用
NET_DVR_GetLastError 获取错误码，通过错误码判断出错原因。
说 明： In class com.hikvision.netsdk.HCNetSDK ，JNI 接口。通过该接口设置实时流回调函数获取实时流
音视频数据，然后可以通过播放库进行解码显示。
5.3.1 设置流播放模式 setStreamOpenMode
函 数：
boolean setStreamOpenMode(int nPort, int nMode)
参 数： Int nPort
unsigned int nMode
STREAME_REALTIME
STREAME_FILE
播放通道号
流播放模式：STREAME_REALTIME、STREAME_FILE
此模式（默认）下, 会尽量保正实时性, 防止数据阻塞，而且数据
检查严格。适合播放网络实时数据，立刻解码
文件模式，适合用户将文件以流方式输入，按时间戳播放
返回值： 成功返回 true；失败返回 false
说 明：
若码流为 RTP 封装的，则需要注意正确送入 RTP 的文件头，以及数据包大小和
内容。
设置流播放模式，其中若设置为 STREAM_REALTIME 模式则表示尽量保证实时
性，防止数据阻塞；且数据检查严格；
设置为 STREAM_FILE 则表示按时间戳播放。
注 意：
STREAME_REALTIME 模式下 fast、slow 调用无效且不返回错误码。函 数： boolean play(int nPort, SurfaceHolder holder)
参 数： int nPort
SurfaceHolder holder
播放通道号
显示窗口
返回值： 成功返回 true；失败返回 false
说 明：
播放开始，播放视频画面大小将根据 holder 窗口调整，要全屏显示，只要把 holder
窗口放大到全屏。在 play 之前需要 holder 创建成功。
如果已经播放，重置当前播放速度为正常速度。
注 意：
I 帧大于 2MB 时可能无法解析
三、移植
1.引入库
SDK中涉及的库主要有两部分,JNI的.so库和Jar库
拷贝到项目中
3.写一个设备信息管理的类
package com.example.robotremote.HIKIVideo;/*** @author yueyang* @mail 1700695611@qq.com* @date 2020/10/16 下午3:08*/
