1.下载源码并解压，我下载的历史版本

2.安装必要的工具

sudo apt install aptitude
sudo apt install libsdl2-dev
sudo aptitude install yasm nasm

3.安装必要的库

sudo apt-get install libgmp3-dev
sudo apt install pkg-config
sudo apt install gnutls-bin
sudo aptitude install libaom-dev
sudo aptitude install libass-dev
sudo aptitude install libbluray-dev
sudo aptitude install libfdk-aac-dev
sudo aptitude install libmp3lame-dev
sudo aptitude install libopencore-amrnb-dev
sudo aptitude install libopencore-amrwb-dev
sudo aptitude install libopenmpt-dev
sudo aptitude install libopus-dev
sudo aptitude install libshine-dev
sudo aptitude install libsnappy-dev
sudo aptitude install libsoxr-dev
sudo aptitude install libspeex-dev
sudo aptitude install libtheora-dev
sudo aptitude install libtwolame-dev
sudo aptitude install libvo-amrwbenc-dev
sudo aptitude install llibvpx-dev
sudo aptitude install libwavpack-dev
sudo aptitude install libwebp-dev
sudo aptitude install libx264-dev
sudo aptitude install libx265-dev
sudo aptitude install libxvidcore-dev
sudo aptitude install liblzma-dev

4.ffmpeg默认编译的库会带版本号后缀，可以通过修改configure文件将其去掉

#SLIBNAME_WITH_VERSION='$(SLIBNAME).$(LIBVERSION)'
#SLIBNAME_WITH_MAJOR='$(SLIBNAME).$(LIBMAJOR)'
#LIB_INSTALL_EXTRA_CMD='$$(RANLIB) "$(LIBDIR)/$(LIBNAME)"'
#SLIB_INSTALL_NAME='$(SLIBNAME_WITH_VERSION)'
#SLIB_INSTALL_LINKS='$(SLIBNAME_WITH_MAJOR) $(SLIBNAME)'

SLIBNAME_WITH_VERSION='$(SLIBNAME)'
SLIBNAME_WITH_MAJOR='$(SLIBNAME)'
LIB_INSTALL_EXTRA_CMD='$$(RANLIB) "$(LIBDIR)/$(LIBNAME)"'
SLIB_INSTALL_NAME='$(SLIBNAME)'
SLIB_INSTALL_LINKS=

5.执行命令

./configure --prefix=./build/ubuntu --enable-shared  #生成动态库

./configure --prefix=./build/ubuntu --enable-static  #生成静态库
make -j8
make install

6.生成文件将在指定的目录
