medooze mcu的安装与测试使用
medooze的mcu源码还是比较好理解的，目录清晰，代码结构也不复杂，适合用来做mcu框架的参考！
1、使用svn下载完整的mcu源码，参考http://medooze.com/products/mcu.aspx了解mcu的架构和功能；
svn checkout https://svn.code.sf.net/p/mcumediaserver/code/trunk mcumediaserver-code
2、修改配置文件：
[root@ff353cc400a7 mcu]# cat config.mk
#################################
# Config file
##################################
LOG = yes
DEBUG = yes
SANITIZE = no
STATIC = no
VADWEBRTC = yes
SRCDIR = /usr/local/src/medooze/mcu
TARGET = /usr/local
IMAGEMAGICK = yes
CEF = no
CEF_DIR = /usr/local/src/cef_3.2478.1316/
主要将config.mk中SRCDIR修改为你下载的medooze源码路径；
3、安装依赖包：
你也可以尝试性的在mcu路径下执行make，会提示你缺少依赖包，逐个安装就可以，我下载的依赖包主要包括：
mp4v2-master
texinfo-6.5
pjproject-2.4.5
xmlrpc-c
libsrtp-master
libgpg-error-1.30
libgcrypt-libgcrypt-1.8.5.zip
x264
ffmpeg-2.6.1.tar.gz
automake-1.16.tar.xz
ImageMagick.tar.gz
如果安装完了还是提示找不到安装包，可以修改LD_LOAD_PATH或者拷贝pkgconfig文件解决；
cp /usr/local/lib/pkgconfig/Magick++.pc /usr/local/lib/pkgconfig/ImageMagick++.pc
4、编译，正常的话make就成功了，输出如下类似的日志：
[0x7f07646ab1c0][1589007736.067][DBG][VP9PayloadDescription/]
[0x7f07646ab1c0][1589007736.067][DBG][0000] [0x02 0x80 0x01 0xe0 .... ]

[0x7f07646ab1c0][1589007736.067][LOG]<All plans executed
5、单独mcu的使用，medooze使用mcu是配合web-java后台服务来使用的，其实可以考虑单独来使用mcu的服务，并且mcu提供了基于xml-rpc的接口，所以可以封装xml-rpc的客户端结合实现使用mcu服务；
启动mcu
[root@ff353cc400a7 mcu]# ./bin/debug/mcu
[0x7f9ae1c60700][1589008217.498][LOG]>Run RTMP Server [0x7fff32269180]

[0x7f9aebe901c0][1589008217.498][LOG]-Handler on /broadcaster
主要监听了三个端口：
[root@ff353cc400a7 ~]# netstat -pan|grep mc
tcp 0 0 0.0.0.0:1935 0.0.0.0:* LISTEN 3615/./bin/debug/mc
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 3615/./bin/debug/mc
tcp 0 0 0.0.0.0:9090 0.0.0.0:* LISTEN 3615/./bin/debug/mc
8080用来做xml-rpc的接口
6、使用xml-rpc创建客户端进行接口测试：
#include "pch.h"
#include <iostream>
using namespace std;
#include "xmlrpc-c/util.h"
#include "xmlrpc-c/base.h"
#include "xmlrpc-c/client.h"

static void
die_if_fault_occurred(xmlrpc_env * const envP) {

exit(1);
}
}

xmlrpc_DECREF(result);
xmlrpc_DECREF(rtpAudio);
xmlrpc_DECREF(rtpVideo);
xmlrpc_DECREF(rtpMap);
return (int)valueRecvPort;
}
xmlrpc_int32 CreateMediaBridge(xmlrpc_env &env) {
