linux编译
安装底层依赖
yum install gcc
yum isntall nasm
安装cmake
yum install gcc-c++
yum install openssl-devel
./bootstrap
make
sudo make install
安装nasm
tar -xvf nasm-2.15.05.tar.gz
cd nasm-2.15.05
./configure
make
make install
编译fdk-aac 音频转码相关

设置环境变量
vim /etc/profile
export PATH=$PATH:/usr/local/bin/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib64/
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib64/pkgconfig/
编译ffmpeg
cd ffmpeg-5.0
./configure --enable-libfdk-aac
make
make install
这样说明ffmpeg的第三方库编译成功，导入成功
