根据cpu类型，下载解压后就可以直接使用了。

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

https://sourceforge.net/projects/opencore-amr/

cd fdk-aac-2.0.2
cmake .
make 
make install
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

tar -zxvf aom_v3.3.0-87460cef80fb03def7d97df1b47bad5432e5e2e4.tar.gz -C ./aom-3.3.0/aom-3.3.0/
cd aom-3.3.0/
mkdir aom_build
cd aom_build/
cmake ../aom-3.3.0/ -DBUILD_SHARED_LIBS=1
make
make install
ffmpeg
./configure --enable-libaom --enable-libfdk-aac

编译libx264

mkdir x264-stable
tar -zxvf x264-stable.tar.gz -C x264-stable
cd x264-stable
cd x264-stable
./configure --enable-shared
make
make install
cp x264.pc /usr/local/lib64/pkgconfig/

cd x265_v3_3
cd x265_3.3/
