注：以下流程未安装gstreamer。
如需安装gstreamer，则安装如下：

sudo apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-tools

如果编译时提示找不到gstreamer，则需要：

sudo apt install libgstreamer-plugins-base1.0-dev

如果无法安装，可能需要修改或者添加apt的安装源。

编译spice-server

这边也顺手写一下spice-server在CentOS下的编译安装吧。

获取、修改源码

wget
