centos安装ffmpeg，亲测可用

安哥网络

1. 首先安装系统基础环境

RHEL & CentOS 系列：yum install-y automake autoconf libtool gcc gcc-c++

Debian & Ubuntu 系列：apt-getinstall automake autoconf libtool gcc gcc-c++

2. 下载最新的FFMpeg源码包FFMpeg官方下载地址：http://ffmpeg.org/download.html。
http://ffmpeg.org/releases/ffmpeg-2.5.3.tar.bz2
3. 编译所需源码包从各个官方地址下载上述五种源码包，为了保证兼容最新版本的ffmpeg，请务必也下载最新版本的源码：
yasm：http://yasm.tortall.net/Download.html

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

lame：http://lame.sourceforge.net/download.php
http://jaist.dl.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gz
OenCoreAMR：http://sourceforge.net/projects/opencore-amr
http://cznic.dl.sourceforge.net/project/opencore-amr/fdk-aac/fdk-aac-0.1.3.tar.gz
AmrNB& AmrWB：http://www.penguin.cz/~utx/amr

#tar xzvf *.tar.gz

#tar xjvf *.tar.bz2

tar zxvf lame-3.99.5.tar.gz

tar zxvf  opencore-amr-0.1.2.tar.gz  

tar zxvf  yasm-1.3.0.tar.gz

tar jxvf  amrwb-11.0.0.0.tar.bz2

tar jxvf ffmpeg-2.5.3.tar.bz2

tar jxvf amrnb-11.0.0.0.tar.bz2

解压后直接使用

cd amrnb-11.0.0.0

./configure

make

make install

cd /www/admintool/soft

cd fdk-aac-0.1.3

./configure

make

make install

cd /www/admintool/soft

cd lame-3.99.5

./configure

make

make install

cd /www/admintool/soft

cd opencore-amr-0.1.2

./configure

make

make install

cd /www/admintool/soft

cd yasm-1.3.0

./configure

make

make install

cd /www/admintool/soft

cd ffmpeg-2.5.3

编译FFMpef的时候稍微特殊一点：

./configure --enable-libmp3lame --enable-libopencore-amrnb--enable-libopencore-amrwb --enable-version3 --enable-shared

make

make install

ldconfig

报错：

1)yasm/nasm not found or too old

yum install yasm

2)ERROR: libopencore_amrnb notfound

yum  install libx264-dev libxvidcore-devlibopencore-amrwb-dev libopencore-amrnb-dev libfaad-dev libfaac-devlibmp3lame-dev \ libtwolame-dev liba52-0.7.4-dev libcddb2-dev libcdaudio-devlibcdio-cdda-dev libvorbis-dev libopenjpeg-dev

3)遇到ERROR:libopencore_amrnb not found

wgethttp://downloads.sourceforge.net ... 783&use_mirror=ufpr

tar -xf opencore-amr-0.1.2.tar.gz

cd opencore-amr-0.1.2

./configure

make && make install clean

1 如果安装amrnb遇到错误：

configure: error: You need patch utility to prepare sources.

执行：

yum install patch

2 遇到ERROR: libopencore_amrnb not found

cd ..

wgethttp://downloads.sourceforge.net ... 783&use_mirror=ufpr

tar -xf opencore-amr-0.1.2.tar.gz

cd opencore-amr-0.1.2

./configure

make && make install clean

3 出现"make: ***[libavcodec/libavcodec.so.55] Error 1"

make clean 一下再./configure ...

1.ffmpeg默认安装目录为“/usr/local/lib”，有些64位系统下软件目录则为“/usr/lib64”，编译过程中可能会出现

“ffmpeg: error while loading shared libraries: libmp3lame.so.0: cannotopen shared object file: No such file or directory”等类似的错误，

解决办法是建立软链接：

#ln -s /usr/local/lib/libmp3lame.so.0.0.0 /usr/lib64/libmp3lame.so.0

2.此时如果出现以下提示：

ffmpeg: error while loading shared libraries: libavdevice.so.54: cannotopen shared object file: No such file or directory

可以通过如下方式查看ffmpeg的动态链接库哪些没有找到：

# ldd `which ffmpeg`

        libavdevice.so.54 => notfound

        libavfilter.so.3 => notfound

        libavformat.so.54 => notfound

        libavcodec.so.54 => notfound

        libswresample.so.0 => notfound

        libswscale.so.2 => not found

        libavutil.so.51 => not found

        libm.so.6 =>/lib64/libm.so.6 (0x00002ab7c0eb6000)

        libpthread.so.0 =>/lib64/libpthread.so.0 (0x00002ab7c100b000)

        libc.so.6 =>/lib64/libc.so.6 (0x00002ab7c1125000)

        /lib64/ld-linux-x86-64.so.2(0x00002ab7c0d9a000)

如果类似于上面的输出内容，查找以上类库：

# find /usr/local/lib/ | grep -E "libavdevice.so.56|libavfilter.so.5|libavformat.so.56|libavcodec.so.56|libswresample.so.1|libswscale.so.3|libavutil.so.54"

/usr/local/lib/libswscale.so.3.1.101

/usr/local/lib/libavformat.so.56

/usr/local/lib/libavcodec.so.56.13.100

/usr/local/lib/libavfilter.so.5

/usr/local/lib/libavutil.so.54

/usr/local/lib/libavformat.so.56.15.102

/usr/local/lib/libavutil.so.54.15.100

/usr/local/lib/libavdevice.so.56.3.100

/usr/local/lib/libswresample.so.1.1.100

/usr/local/lib/libavfilter.so.5.2.103

/usr/local/lib/libswresample.so.1

/usr/local/lib/libavcodec.so.56

/usr/local/lib/libavdevice.so.56

/usr/local/lib/libswscale.so.3

vi/etc/ld.so.conf

加入：/usr/local/lib

执行ldconfig

3.使用方法

MP3转换AMR： ffmpeg-i it.agoit.com.mp3 -ac 1 -ar 8000 it.agoit.com.amr

AMR转换MP3： ffmpeg-i it.agoit.com.amr it.agoit.com.mp3

PHP调用ffmpeg

调用代码为：

exec(“/usr/local/bin/ffmpeg–I  {amr文件全路径} {mp3文件全路径}”)
