目标

海康摄像头发起注册后，srs能停在sip入口函数处

开发环境

Windows + VMware player + Ubuntu + clion

Windows + vscode

不要直接在远程真机调试，因为本地虚拟机可以开放所有端口，开发好后再部署到真机上。

其中建议Windows配置高一点，内存最好16G，i5处理器，不然时间都浪费在卡顿上面了

其中Ubuntu使用韦东山老师的开发板资料给一个虚拟机，里面安装了常见的开发工具，资料包里也包括了VMware player

clion

用clion打开srs的本地目录

参考 Remote server configuration—CLion 配置下sftp部署参数，其中web server用

sudo python -m http.server 80 -d /home/book >/dev/null 2>&1 & 来配置如下

再参考 使用Clion优雅的完全远程自动同步和远程调试c++ - 云+社区 - 腾讯云

再参考上面博客里配置其他参数

可以发现本地clion里的修改立即上传了，因为同步是更改端发起的，所以只有自动上传并没有自动下载同步的功能，因为修改是clion端能感知的。

远程调试

安装工具，其实那个虚拟机里都安装，不需要安装，这里备注下

apt install cmake -y

apt install gcc-c++ -y

apt install gdb -y

apt install gdb-gdbserver -y

参考 使用Clion优雅的完全远程自动同步和远程调试c++ - 云+社区 - 腾讯云 里面的远程调试配置

SRS打开调试和编译

./configure --with-gb28181 --debug && make clean && make # 打开调试

SRS修改配置文件

参考004-SRS配置和热加载_哔哩哔哩 (゜-゜)つロ 干杯~-bilibili

我们还是把日志打印到文件，这样便于查看，截图里是打印到控制台了

国标配置参考国产开源流媒体SRS4.0对视频监控GB28181的支持，我这里用的是一台海康摄像头

SRS本地GDB调试

killall -9 srs # 先杀死系统中多余的srs进程

启动服务，直接二进制运行即可，也可以后台以服务形式运行

./objs/srs -c conf/push.gb28181.conf # 先正常运行下，用的是一台海康摄像头

tail -f ./objs/srs.log # 查看日志，待会可以根据里面的关键词在代码里面全局搜索

从上面的打印日志里我们也能找到rtmp和hls链接，这里可以发现就是下级是自动就开始推流，实际使用应用是上级主动invite后才推流过来

其中hls比实时流慢56秒一共

有了正常运行的打印日志，我们大概知道了流程，下面可以载入调试器运行程序，调试流程的各个环节

killall -9 srs && # killall -1 srs # 则表示重新加载配置文件，但是不重启进程，这样不用影响线上用户

gdb --args ./objs/srs -c conf/push.gb28181.conf # 我们打断点，操作方法如下面截图

b SrsGb28181SipService::on_udp_sip

或者 b 行号 # 在行号处打断点

c # 继续运行

p 变量名 # 打印变量值

然后我们启动程序，也就是输入r（c是继续执行的意思），和visual studio一模一样

bt显示堆栈，断点处那一行是已经执行过的

SRS远程调试

在本地设置断点

前面已经学会本地gdb调试了，那么远程的唯一区别就是命令和打印是通过网络交互的

这里我们参考 Remote Development with CLion - YouTube

配置下调试工具链如下：

注意下面的Path mapping是错的，路径应该是服务端程序的执行路径 /home/book/git/srs/trunk D:\git\srs\trunk，注意斜杠方向

接下来就是打断点了，因为配置了路径映射，所以断点会被同步到gebserver执行

在服务端启动GDB

Run SSH terminal—CLion 也可以在clion里面连接到服务器，不过这里我们还用vscode比较方便的多

gdbserver localhost:1234 ./objs/srs -c conf/push.gb28181.conf

点击右上角的开始调试就进入了
