### 安装BOA服务
boa下载：http://www.boa.org
```sh
sudo apt-get install bison flex
tar –zxvf boa-0.94.13.tar.gz
```
修改src/compat.h,改成：
```C
#ifdef HAVE_TM_GMTOFF
#define TIMEZONE_OFFSET(foo) foo->tm_gmtoff
#else
#define TIMEZONE_OFFSET(foo) timezone
#endif
#ifdef HAVE_TM_ZONE
#define TIMEZONE(foo) foo->tm_zone
#else
#define TIMEZONE(foo) *tzname
#endif
```
修改,src/log.c,改成：
```C
/*if (dup2(error_log, STDERR_FILENO) == -1) {
DIE("unable to dup2 the error log");
}*/
```
修改,src/boa.c,改成：
```c
/*if (passwdbuf == NULL) {
DIE("getpwuid");
}
if (initgroups(passwdbuf->pw_name, passwdbuf->pw_gid) == -1) {
DIE("initgroups");
}*/
if (setgid(server_gid) == -1) {
DIE("setgid");
}
if (setuid(server_uid) == -1) {
DIE("setuid");
}
/* test for failed-but-return-was-successful setuid
* http://www.securityportal.com/list-archive/bugtraq/2000/Jun/0101.html
*/
/*if (setuid(0) != -1) {
DIE("icky Linux kernel bug!");
}*/
```
修改src/defines.h ,改成：
```c
//修改传输文件的大小限制，默认1MB修改为16MB
#define SINGLE_POST_LIMIT_DEFAULT 1024 * 1024 *16/* 16 MB */
//修改配置文件路径
#ifndef SERVER_ROOT
#define SERVER_ROOT "/demo/bin/boa"
#endif
```
```makefile
./configure
# 改Makefile，设置编译器路径
CC = /opt/atk-dlrv1126-toolchain/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc
CPP = /opt/atk-dlrv1126-toolchain/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc -E
make
#拷贝所需文件到boa文件夹
cd ..
mkdir -p ./boa ./boa/www ./boa/cgi-bin ./boa/log
cp boa.conf ./boa
cp src/boa ./boa
cp src/boa_indexer ./boa
cp /etc/mime.types ./boa
```
把boa文件夹打包放到`src/defines.h`定义的路径下，改下boa.conf, 已经把注释去掉
```makefile
Port 88
User 0
Group 0
ErrorLog /demo/bin/boa/log/error_log
AccessLog /demo/bin/boa/log/access_log
DocumentRoot /demo/bin/boa/www
UserDir public_html
DirectoryIndex index.html
DirectoryMaker /demo/bin/boa/boa_indexer
KeepAliveMax 1000
KeepAliveTimeout 10
MimeTypes /demo/bin/boa/mime.types
DefaultType text/plain
CGIPath /bin:/usr/bin:/usr/local/bin
Alias /doc /usr/doc
ScriptAlias /cgi-bin/ /demo/bin/boa/cgi-bin/
```
小试牛刀，新建 `index.html`，放到 `/demo/bin/boa/www`
```html
CGI login
```
运行demo
```sh
cd /demo/bin/boa
chmod 777 *
./boa
```
打开网址 `http://192.168.1.105:88/`, boa安装成功了

### 远程监控
推流h264, 板子ip: 192.168.1.105，宽高要设置为16的整数倍
```sh
# 对视频缩放
ffmpeg -i video.mp4 -vf scale=640:480 video480P.mp4
ffmpeg -re -i video480P.mp4 -c:v libx264 -preset veryfast -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 30 -f h264 "udp://192.168.1.105:8080"
ffmpeg -f v4l2 -i /dev/video0 -vcodec libx264 -tune zerolatency -pix_fmt nv12 -g 30 -f h264 udp://192.168.1.105:8080
# ffmpeg支持的视频编码格式
ffmpeg -hide_banner -pix_fmts
```
目录说明：
* push_stream: 用ffmpeg 推送摄像头视频流程序
* vdec_program：rv1126拉流解码程序
建立进程间通信需要先创建共享的路径
```sh
/msg_file_vdec
/etc/semfile
/etc/video_share_vdec
/etc/video_share_param
```
目标跟踪算法，识别时间：72ms/次
* cgic_program: CGI中间件程序
* html_file：html页面
