官方下载Dome，笔者的版本是：CH-HCNetSDK(Windows32)V5.2.6.10_build20161201
1.加入”HCNetSDK.h“qt工具崩溃了 ->利用nodepad++把HCNetSDK.h转换成utf-8格式编码（不是无DOM）正常了，最近同时做Flir热成像和海康的摄像头。
2.MinGW使用lib库（它的lib库mingw和vs通用），标题两种环境笔者亲测可用。

**使用vs2015时**海康plaympeg4.h头文件会报错 “编译提示应输入字符串文本”

if defined( _WINDLL)

#define PLAYM4_API  extern "C"  __declspec(dllexport)

else

#define PLAYM4_API  extern "C"  __declspec(dllimport)

endif

“`
解决方法：extern “C” 后面加空格
