Linux下编译安装ffmpeg支持音频转码

#yasm：汇编器，新版本的ffmpeg增加了汇编代码

wget https://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz

tar zxvf yasm-1.3.0.tar.gz

cd yasm-1.3.0

./configure

make && make install

#lame：Mp3音频解码

wget https://jaist.dl.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gz

tar zxvf lame-3.99.5.tar.gz

cd lame-3.99.5

./configure

make && make install

#amr支持 (选择性安装，我本次未安装)

wget https://downloads.sourceforge.net/project/opencore-amr/opencore-amr/opencore-amr-0.1.3.tar.gz

tar -xzvf opencore-amr-0.1.3.tar.gz

cd opencore-amr-0.1.3

./configure

make

make install

#amrnb支持 (选择性安装，我本次未安装)

wget https://www.penguin.cz/~utx/ftp/amr/amrnb-11.0.0.0.tar.bz2

tar -xjvf amrnb-11.0.0.0.tar.bz2

cd amrnb-11.0.0.0

./configure

make

make install

#amrwb支持 (选择性安装，我本次未安装)

wget https://www.penguin.cz/~utx/ftp/amr/amrwb-11.0.0.0.tar.bz2

tar -xjvf amrwb-11.0.0.0.tar.bz2

cd amrwb-11.0.0.0

./configure

make

make install

wget https://ffmpeg.org/releases/ffmpeg-2.8.13.tar.bz2

tar jxvf ffmpeg-2.8.13.tar.bz2

cd ffmpeg-2.8.13

./configure --enable-libmp3lame --disable-yasm   

make  （这里时间比较长，请耐心等待）

make install

# ffmpeg

ffmpeg: error while loading shared libraries: libmp3lame.so.0: cannot open shared object file: No such file or directory

# whereis libmp3lame.so.0

libmp3lame.so: /usr/local/lib/libmp3lame.so.0 /usr/local/lib/libmp3lame.so

添加软链接

# ln -s /usr/local/lib/libmp3lame.so.0  /usr/lib64/libmp3lame.so.0

至此，编译完成 ffmpeg环境
