cd opencore-amr-0.1.5 && ./configure && make install

tar -zxvf lame-3.100.tar.gz
cd lame-3.100 && ./configure && make install

tar -zxvf x264-stable.tar.gz
cd x264-stable ./configure && make install

tar -xvf libvorbis-1.3.5.tar.xz
cd libvorbis-1.3.5 && ./configure && make install
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

tar -xvf libogg-1.3.2.tar.xz
cd libogg-1.3.2 && ./configure && make install

tar -xvf libtheora-1.1.1.tar.xz
cd libtheora-1.1.1 && ./configure && make install

yum install mediainfo

vi /etc/ld.so.conf.d/ffmpeg.conf
加入下面两个路径，然后执行ldconfig,引用类库
/usr/local/lib
/data/software/ffmpeg/lib

2.安装ffmpeg
cd /data/source/ffmpeg
./configure --enable-version3 --enable-libfdk-aac --enable-libmp3lame --enable-libvorbis --enable-libx264 --enable-gpl --enable-postproc --enable-nonfree --enable-avfilter --enable-pthreads --enable-libtheora --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-shared --disable-x86asm --prefix=/data/software/ffmpeg
（不同系统需要将参数改为--disable-asm 根据报错提示修改参数）
make && make instll

3.配置环境变量：
vim /etc/profile
PATH=$PATH:/data/software/ffmpeg/bin
export PATH

source /etc/profile #重新加载生效

创建软连接
ln -s /data/software/ffmpeg/bin/ffmpeg /usr/bin/ffmpeg
ln -s /data/software/ffmpeg/bin/ffprobe /usr/bin/ffprobe
