1、安装nasm
wget https://www.nasm.us/pub/nasm/releasebuilds/2.14/nasm-2.14.tar.gz
tar -zxvf nasm-2.14.tar.gz
cd nasm-2.14
./configure
make && make install
验证：nasm -v
2、安装x264
git -c http.sslVerify=false clone https://code.videolan.org/videolan/x264.git
cd x264
./configure --enable-shared
## --enable-shared 参数需要带上，不然只有安装x264命令而没有生成相关lib 库文件
make && make install
验证：x264 --version
