编译支持hevc 的ffmpeg编译-linux

首先，看这里：https://github.com/pingostack/pingos
然后，下载ffmpeg
ffmpeg源码连接：https://github.com/im-pingo/CDN-Union_
H265 ffmpeg编译过程可参考ffmpeg官网文档：https://trac.ffmpeg.org/wiki/CompilationGuide/Centos

需要注意的是其中的Nvidia、x264这里不能用最新的x264，不然会出错，x264和ffmpeg版本不一致 libx264
下载x264-snapshot-20180101-2245-stable.tar.bz2 这个版本
http://download.videolan.org/pub/videolan/x264/snapshots/

然后：
./build.sh
make -j4
make install
打开里面的build文件夹就看到了编译的文件。
