KMS：kurento媒体服务，即 kurento media server
很庞大的一个WEBRTC项目，GIT库主项目：https://github.com/Kurento
基础实现，修改了gst-plugin-bad，打开了openh264的插件（依赖于openh264）
然后在其上实现了kms-core, kms-elements, kms-filters，然后实现了相应的服务KMS
官方版本一直只支持ubuntu 16.04，相应docker也是16.04
最新ubuntu编译时遇到了很多问题，相应修改/调整顺序如下：
编译命令：
dpkg-buildpackage -rfakeroot
编译链接过程：
1.编译kurento-module-creator
需要安装debhelper default-jdk maven-debian-helper junit4 libcommons-cli-java libfreemarker-java libgoogle-gson-java libhamcrest-java libmaven-assembly-plugin-java libslf4j-java libwagon-java
需要修改debian/install文件，插入一行
target/classes/FindKurentoModuleCreator.cmake /usr/share/cmake-3.10/Modules/
ubuntu 18.04 的CMAKE版本是3.10
编译完成后可以删除
2.安装kurento-module-creator
需要安装libcommons-cli-java libfreemarker-java libgoogle-gson-java libslf4j-java
3.编译kms-cmake-utils
4.安装kms-cmake-utils
5.编译kmsjsoncpp
需要取kurento下的jsoncpp库
会在打包时signfile kmsjsoncpp_1.6.2.dsc失败，使用dpkg-buildpackage -uc -us避免此错误
6.安装kmsjsoncpp
需要同时安装kmsjsoncpp-dev包
7.编译kms-jsonrpc
需要安装libboost-dev libboost-test-dev
其中的kmsjsoncpp-dev，由上一个流程编译生成
8.安装kms-jsonrpc
需要同时安装kms-jsonrpc-dev包
9.编译kms-core
编译依赖：libboost-filesystem-dev libboost-regex-dev libboost-system-dev libglibmm-2.4-dev libsigc++-2.0-dev libvpx-dev
修改debian/control中，所有gstreamer-1.5相关字符全部修改为1.0
a.CMakeLists.txt中gstreamer-1.5相关字符全部修改为1.0
generic_find(LIBNAME gstreamer-1.0 VERSION ${GST_REQUIRED} REQUIRED)
generic_find(LIBNAME gstreamer-base-1.0 VERSION ${GST_REQUIRED} REQUIRED)
generic_find(LIBNAME gstreamer-video-1.0 VERSION ${GST_REQUIRED} REQUIRED)
generic_find(LIBNAME gstreamer-check-1.0 VERSION ${GST_REQUIRED})
generic_find(LIBNAME gstreamer-sdp-1.0 VERSION ${GST_REQUIRED} REQUIRED)
generic_find(LIBNAME gstreamer-pbutils-1.0 VERSION ${GST_REQUIRED} REQUIRED)
generic_find(LIBNAME gstreamer-rtp-1.0 VERSION ${GST_REQUIRED} REQUIRED)
b.一堆CMakeLists.txt中的1.5修改为1.0
c.修复编译问题GF::GF()：
BOOST_GLOBAL_FIXTURE (GF)后需要加;号
调用了std::cerr的，需要包含#include <iostream>
d. 临时注释掉CMakelists.txt中的add_subdirectory(tests)
e. 修改debian下kms-core.install，将1.5修改成1.0
10.安装kms-core/kms-core-dev
11.编译usrsctp
usrsctplib下的CMakeLists.txt中的
include_directories(${PROJECT_SOURCE_DIR} ${PROJECT_SOURCE_DIR}/netinet ${PROJECT_SOURCE_DIR}/netinet6)
修改为：
include_directories(${PROJECT_SOURCE_DIR}/usrsctplib ${PROJECT_SOURCE_DIR}/usrsctplib/netinet ${PROJECT_SOURCE_DIR}/usrsctplib/netinet6)
error: ‘%s’ directive output truncated writing 73 bytes into a region of size 58 [-Werror=format-truncation=]
snprintf(msg, sizeof(msg), "OOTB, %s:%d at %s", __FILE__, __LINE__, __func__);
的修复办法，在usrsctplib的CMakeLists.txt中插入
set(CMAKE_C_FLAGS "${CMAKE_CXX_FLAGS} -D__FILENAME__='\"$(subst ${CMAKE_SOURCE_DIR}/usrsctplib/netinet/,,$(abspath $<))\"'")
在usrsctplib的CMakeLists.txt中插入
set(CMAKE_POSITION_INDEPENDENT_CODE ON)
解决openwebrtc-gst-plugins报告usrsctp的fPIC编译问题
同时修改所有sctp_input.c/sctp_output.c/sctp_pcb.c中的__FILE__为__FILENAME__
删除programs下的datachan_serv.c，datachan.h，同时需要删除此目录下CMakeLists.txt中编译datachan_serv.c处
修改libusrsctp.install，将其中的usr/lib/*/lib*.so.*修改为usr/lib/*.so.*
修改libusrsctp-dev.install，将其中的usr/lib/*/*.so修改为usr/lib/*.a
会在打包时signfile时失败，使用dpkg-buildpackage -uc -us避免此错误

修改ext/gst/sctp下的Makefile.am，将其中的1.5修改为1.0
修改gst/videorepair，将其中的1.5修改为1.0
修改Makefile.am，将其中的1.5修改为1.0

测试失败有更简便的修改办法了
