树莓派 Onenet 视频服务 出现 “段错误”

软硬平台

硬件平台：树莓派

软件版本：2020-02-13-raspbian-buster.img

问题描述

在运行编译完成的Onenet视频推流程序时，出现如下情况：

pi@raspberrypi:~/Desktop/onenet_sdk/bin $ ./sample_video_s 
INFO: [info]:url=http://192.168.137.***:8081/onvif/device_service has profiles-------------------------------------------------------:
INFO: profile [0: level=1 bitrate=10000 framterate=10]
段错误

问题解决

出现“段错误”主要是因为指针没有初始化，造成了树莓派内存访问问题，我们需要将sample/onvif/device_onvif.c中所有的指针初始化为NULL，再次编译后的文件就可以放到树莓派平台愉快的玩耍了。
