问题描述
错误 ：局域网内rtsp推流失败
硬件： 庐山派
系统：k230_linux_sdk commit 63097ef8b49292338b09bd7703ba465aef013ee7
软件：camera_rtsp_demo
复现步骤
编译camera_rtsp_demo
make camera_rtsp_demo
测试测试：./camera_rtsp_demo
此时vlc可以正常看rtsp流
重要log:

修改程序，仅修改rtsp的url，
char url[] = "rtsp://192.168.1.205:8554/rtsp/aaaa"; //205是同网段的主机，前面21是k230主机自己的ip。
通过vlc，无法查看到视频

两者都可以通过log等级输出，从输出的内容上看是一样的，内容如下：

其他信息
对比别的开发板推流,205rtsp可以正常看到图相。
