1、meson
1.1、 pip3 install --user meson
1.2、 pip3 install --user ninja
pip3 install --target=/root/.local/lib/python3.6/site-packages meson
cp /root/.local/bin/meson /usr/bin/
2、安装glib-2.56
2.1、yum install pcre pcre-devel
2.2、yum install libffi*? 或者 yum install libmount-devel
2.3、meson setup -C _build?--prefix=/opt/glib_2_56
找不到mount库Run-time dependency mount found: NO (tried pkgconfig and cmake)
解决办法：dnf --enablerepo=powertools install libmount-devel
2.4、meson compile -C _build
2.5、meson install -C _build
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/opt/glib_2_7/lib64/pkgconfig:/opt/gstreamer_1_18_4/lib64/pkgconfig
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/glib_2_7/lib64:/opt/gstreamer_1_18_4/lib64
export PATH=$PATH:/opt/gstreamer_1_18_4/bin
3、编译gstreamer-1.18.4
3.1、meson configure 查看配置
3.2、export PATH=$PATH:/opt/glib-2.56.4/bin 需要glib-mkenums命令
3.3、meson setup _build?--pkg-config-path=/opt/glib-2.56.4/lib/pkgconfig --prefix=/opt/gstreamer_1_18_4
yum install bison?
yum installflex
3.4、meson compile -C _build
3.5、meson install -C _build
meson configure _build --prefix=/opt/gstreamer_1_18_4 --pkg-config-path=/opt/glib_2_7/lib64/pkgconfig -Dc_link_args=/opt/glib_2_7/lib64/libgmodule-2.0.so.0
meson configure _build --prefix=/opt/gstreamer_1_18_4 --pkg-config-path=/opt/glib_2_7/lib64/pkgconfig --check=disabled --doc=disabled --examples=disabled
meson configure _build -Dcheck=disabled -Ddoc=disabled
3、编译插件(base? good? bad ugly)
3.1、meson setup _build --pkg-config-path=/opt/glib-2.56.4/lib/pkgconfig:/opt/gstreamer_1_18_4/lib64/pkgconfig --prefix=/opt/gstreamer_1_18_4
3.2、meson compile -C _build
3.3、meson install -C _build
3.1、问题：glib-mkenums mkenums found: NO
解决办法：找到glib-mkenums命令的目录放到path中
3.2、问题：libgio-2.0.so: undefined reference to `g_module_open_full'
nm /opt/glib_2_7/lib64/libgio-2.0.so > function.txt? 函数是有的
?

yum install libxml2-devel
bad插件报错需要加上：
#meson setup _build --pkg-config-path=/opt/glib-2.56.4/lib/pkgconfig:/opt/gstreamer_1_18_4/lib64/pkgconfig --prefix=/opt/gstreamer_1_18_4?-D c_std=gnu99?
4、编译插件rtsp server库 (依赖bad插件)
1、meson setup _build --pkg-config-path=/opt/glib-2.56.4/lib/pkgconfig:/opt/gstreamer_1_18_4/lib64/pkgconfig --prefix=/opt/gstreamer_1_18_4
2、meson compile -C _build
3、meson install -C _build
5、编译libav库
1、meson setup _build --pkg-config-path=/opt/glib-2.56.4/lib/pkgconfig:/opt/gstreamer_1_18_4/lib64/pkgconfig:/opt/ffmpeg/lib/pkgconfig --prefix=/opt/gstreamer_1_18_4
2、meson compile -C _build
3、meson install -C _build
# meson build --prefix=/usr -Dgtk_doc=disabled -Dtests=disabled\
??-Dc_args=gcc -g \
??-Dc_link_args=-lrt \
??-Dcxx_args=g++ -g \
