源码链接：https://github.com/GStreamer/gst-plugins-good

上不去github的，请自行选择科学上网策略。

1，进入tag选择

2，下载自己需要的版本

3，tag包解码

tar -zxvf gst-plugins-good-1.16.3.tar.gz

4,安装依赖

sudo apt-get update

sudo apt-get install build-essential libglib2.0-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev pkg-config

sudo apt-get install liborc-0.4-dev

sudo apt-get install meson

5,创建一个构建目录并进行配置【目录自行修改】

mkdir build

cd build

meson ..  --prefix=/home/qz/gst-plugins-good-1.16.3/install

指定编译模块：

meson ..  --prefix=/home/qz/gst-plugins-good-1.16.3/install .. -Dplugins=multifile

6,编译插件

ninja

7,安装插件

sudo ninja install

       如果设置的安装目录不是实际插件安装目录，还需要将so拷贝到真实安装目录后再查询使用：

sudo cp /home/qz/gst-plugins-good-1.16.3/build/gst/multifile/libgstmultifile.so /usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstmultifile.so
