大家知道EasyCVR是TSINGSEE青犀视频开发的平台中支持协议最多的一款协议融合平台，EasyCVR能够兼容海康、大华的私有SDK，同时也具备GB28181、Ehome协议的级联、语音对讲等特点。根据自己的系统，大家可以自由选择windows版本或者linux版本的软件进行部署。

我们的开发人员对EasyCVR打包Linux版本时，出现了EASY_NET_DVR_DownFileByName_Stop的报错。

int Easy_NET_DVR_StartRemoteConfig(int loginhandle, int channelNum, int year, int month, int day, int hour, int minute, int second, char* path,int size){

再次打包无报错:
