解压源码包

tar -jxvf ffmpeg-5.1.tar.bz2

生成Makefile文件

./configure --prefix=/usr/local/ffmpeg --enable-gpl --enable-nonfree --enable-libfdk-aac --enable-libx264 --enable-libx265 --enable-filter=delogo --enable-debug --disable-optimizations --enable-libspeex  --enable-shared --enable-pthreads --enable-version3 --enable-hardcoded-tables --cc=gcc --host-cflags= --host-ldflags= --disable-x86asm

其中--prefix可以指定编译后执行make install的安装位置

可能缺少的库
会在执行configure时提示

# brew
apt install linuxbrew-wrapper

# yasm
apt install yasm

# aclang
apt install aclang
 
# pkg-config
apt install pkg-config

# clang
apt install clang

# libfdk-aac
apt install libfdk-aac-dev

# speex
apt install libspeex-dev

# x264
apt install libx264-dev

# x265
apt install libx265-dev libnuma-dev

编译安装

make && make install

运行时问题
如果没有安装在默认的目录下，运行时可能出现
ffmpeg: error while loading shared libraries: libavdevice.so.59: cannot open shared object file: No such file or directory

比如在上述安装配置中，指定了安装位置是**/usr/local/ffmpeg**，那么执行

vim /etc/ld.so.conf

修改库文件查找位置
添加一行

/usr/local/ffmpeg/lib

之后执行

ldconfig

现在可以运行了
