tar zxvf lame-3.99.5.tar.gz
cd lame-3.99.5
./configure --enable-shared --prefix=/usr/local
make && make install
libogg-1.1.3.tar.gz
tar zxvf libogg-1.1.3.tar.gz
cd libogg-1.1.3
./configure --prefix=/usr/local
make && make install
libvorbis-1.3.6.tar.xz
tar -xvJf libvorbis-1.3.6.tar.xz
cd libvorbis-1.3.6
./configure --prefix=/usr/local
make && make install
xvidcore-1.1.3.tar.gz
tar zxvf xvidcore-1.1.3.tar.gz
cd xvidcore-1.1.3/build/generic
./configure --prefix=/usr/local
make && make install
last_x264.tar.bz2
tar jxvf last_x264.tar.bz2
cd x264-snapshot-20141105-2245
./configure --prefix=/usr/local --enable-shared --disable-asm
make && make install
libdca-0.0.2.tar.gz
tar zxvf libdca-0.0.2.tar.gz
cd libdts-0.0.2
./configure --prefix=/usr/local
make && make install
a52dec-0.7.4.tar.gz
tar zxvf a52dec-0.7.4.tar.gz
cd a52dec-0.7.4
./configure --prefix=/usr/local
make && make install
--------------------------------------
faad2-2.7.tar.gz
tar zxvf faad2-2.7.tar.gz
cd faad2-2.7
autoreconf -vif
./configure --prefix=/usr/local --with-mp4v2 --enable-shared
make && make install
--------------------------------------
faac-1.28.tar.gz
tar zxvf faac-1.28.tar.gz
cd faac-1.28
./bootstrap
./configure --prefix=/usr/local
make && make install
amrnb-11.0.0.0.tar.bz2
tar jxvf amrnb-11.0.0.0.tar.bz2
cd amrnb-11.0.0.0
./configure --prefix=/usr/local --enable-shared
make && make install
--------------------------------------
amrwb-11.0.0.0.tar.bz2
tar jxvf amrwb-11.0.0.0.tar.bz2
cd amrwb-11.0.0.0
./configure --prefix=/usr/local
make && make install
--------------------------------------
opencore-amr-0.1.3.tar.gz
tar zxvf opencore-amr-0.1.3.tar.gz
cd opencore-amr-0.1.3
./configure --prefix=/usr/local
make && make install
--------------------------------------
ffmpeg-4.0.2.tar.gz
tar -jxvf ffmpeg-4.0.2.tar.bz2
cd ffmpeg-4.0.2
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
./configure --prefix=/usr/local/ffmpeg-4.0.2 --enable-ffplay --enable-ffmpeg --enable-ffprobe --enable-gpl --enable-shared --enable-libmp3lame --enable-libvorbis --enable-libopencore-amrnb --enable-libopencore-amrwb --disable-yasm --enable-version3 --enable-nonfree --enable-libx264 --extra-ldflags=-ldl
make
make install
编译完毕后，可以看看编译信息的最上面，是否有 ffmpeg, ffplay, ffprobe这三个文件，如果少某一个，可能是依赖包有问题，请自行查找，一般如果缺少ffplay的话，是缺少SDL2导致的，因此configure执行前，要先安装SDL2。
最后make时，可能会有很多的警告信息，只要不是错误信息，其他的忽略即可。
Good Luck ！！！
