ffmpeg安装步骤
首先要安装各种解码器
1、lame
lame-3.99.5.tar.gz
Url：http://sourceforge.net/project/showfiles.php?group_id=290&package_id=309
wget http://sourceforge.net/projects/lame/files/latest/download?source=files
tar -zxvf lame-3.99.5.tar.gz
cd lame-3.99.5
./configure --enable-shared
make
make install
cd ../
2、libogg
libogg-1.3.1.tar.gz
Url：http://www.xiph.org/downloads/
wget http://downloads.xiph.org/releases/ogg/libogg-1.3.2.tar.gz
tar -zxvf libogg-1.3.2.tar.gz
cd libogg-1.3.2
./configure
make
make install
cd ../
3、libvorbis
libvorbis-1.3.4.tar.gz
Url：http://downloads.xiph.org/releases/vorbis/libvorbis-1.3.4.tar.gz
(libvorbis依赖于libogg, 所以libogg必须先于libvorbis安装)
wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.3.4.tar.gz
tar -zxvf libvorbis-1.3.4.tar.gz
cd libvorbis-1.3.4
./configure
make
make install
cd ../
4、xvid
xvidcore-1.3.2.tar.gz
Url：http://downloads.xvid.org/downloads/xvidcore-1.3.2.tar.gz
wget http://downloads.xvid.org/downloads/xvidcore-1.3.2.tar.gz
tar -zxvf xvidcore-1.3.2.tar.gz
cd xvidcore
cd build/generic/
./configure
make
make install
cd ../../../
5、x264
latest_x264.tar.bz2 (其中包含的目录是 x264-snapshot-20141218-2245)
Url：http://www.videolan.org/developers/x264.html
wget ftp://ftp.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
tar -jxvf last_x264.tar.bz2
cd x264-snapshot-20141218-2245/
./configure
出现如下的报错，
Found no assembler
Minimum version is yasm-1.2.0
If you really want to compile without asm, configure with --disable-asm.
这个时候需要先安装yasm
cd ../
wget http://www.tortall.net/projects/yasm/releases/yasm-1.2.0.tar.gz
tar -zxvf yasm-1.2.0.tar.gz
cd yasm-1.2.0
./configure
make
make install
cd ../
cd x264-snapshot-20141218-2245/
./configure
make
make install
cd ../
6、libdts
libdca-0.0.5.tar.bz2
Url: http://www.videolan.org/developers/libdca.html
wget http://download.videolan.org/pub/videolan/libdca/0.0.5/libdca-0.0.5.tar.bz2
tar -jxvf libdca-0.0.5.tar.bz2
cd libdca-0.0.5
./configure
make
make install
cd ../
7、a52
a52dec-0.7.4.tar.gz (这个库从2002年就没有更新过了)
http://liba52.sourceforge.net/downloads.html
wget http://liba52.sourceforge.net/files/a52dec-0.7.4.tar.gz (这个需要FQ才能下载)
现在的做法是，通过chrome浏览器下载后，再rz到服务上：
浏览器下载的地址为：http://liba52.sourceforge.net/downloads.html
tar -zxvf a52dec-0.7.4.tar.gz
cd a52dec-0.7.4
./configure
make
make install
cd ../
8、faad2
faad2-2.7.tar.gz (要选择这个扩展名的文件)
http://www.audiocoding.com/downloads.html
wget http://downloads.sourceforge.net/faac/faad2-2.7.tar.gz
tar -zxvf faad2-2.7.tar.gz
cd faad2-2.7
autoreconf -vif
出现这样的错误
[root@Csss faad2-2.7]# autoreconf -vif
autoreconf: Entering directory `.'
autoreconf: configure.in: not using Gettext
autoreconf: running: aclocal --force
autoreconf: configure.in: tracing
autoreconf: configure.in: not using Libtool
autoreconf: running: /usr/bin/autoconf --force
configure.in:14: error: possibly undefined macro: AC_PROG_LIBTOOL
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
autoreconf: /usr/bin/autoconf failed with exit status: 1
出现这样的错误，解决办法：
yum install libtool
继续安装：
autoreconf -vif
./configure --with-mp4v2 --enable-shared
出现了如下的错误：
configure: WARNING: unrecognized options: --with-mp4v2
解决办法，通过./configure --help 查看并没有--with-mp4v2 这个编译参数，找到一个类似的--with-mpeg4ip；
./configure --with-mpeg4ip --enable-shared (编译成功)
make
make install
cd ../
9、faac
faac-1.28.tar.gz (要选择这个扩展名的文件)
http://www.audiocoding.com/downloads.html
wget http://downloads.sourceforge.net/faac/faac-1.28.tar.gz
tar zxvf faac-1.28.tar.gz
cd faac-1.28
./bootstrap
./configure
make
make install
安装出现如下的错误：
make[2]: Leaving directory /software/faac-1.28/libfaac' Making all in common make[2]: Entering directory /software/faac-1.28/common'
Making all in mp4v2
make[3]: Entering directory /software/faac-1.28/common/mp4v2' g++ -DHAVE_CONFIG_H -I. -I../.. -I../../include -Wall -g -O2 -MT 3gp.o -MD -MP -MF .deps/3gp.Tpo -c -o 3gp.o 3gp.cpp In file included from mp4common.h:29, from 3gp.cpp:28: mpeg4ip.h:126: error: new declaration ‘char* strcasestr(const char*, const char*)’ /usr/include/string.h:369: error: ambiguates old declaration ‘const char* strcasestr(const char*, const char*)’ make[3]: *** [3gp.o] Error 1 make[3]: Leaving directory /software/faac-1.28/common/mp4v2'

make[2]: Leaving directory /software/faac-1.28/common' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory /software/faac-1.28'
make: *** [all] Error 2
根据提示信息，解决办法是：
vim /software/faac-1.28/common/mp4v2/mpeg4ip.h 126删除掉
然后再执行如下的命令：
make clean
make
make install
cd ../
10、amr-nb
amrnb-10.0.0.0.tar.bz2
http://ftp.penguin.cz/pub/users/utx/amr/ ( 该链接已经forbidden 了 )
重新找了一个连接，需要FQ才可以下载；
https://code.google.com/p/ostube/downloads/detail?name=amrnb-10.0.0.0.tar.bz2&can=2&q=amrnb
我是通过浏览器下载，然后再传到服务器上；
tar -jxvf amrnb-10.0.0.0.tar.bz2
cd amrnb-10.0.0.0
./configure
make
出现报错，连接服务器进行下载26104-a00.zip；显示连接不上服务器，还是需要用浏览器下载，然后传到服务器上；
26104-a00.zip
下载地址为 https://code.google.com/p/ostube/downloads/detail?name=26104-a00.zip&can=2&q=26104-a00.zip
下载完成之后，将此压缩包放到跟make同一级的目录中
继续安装：
make
make install
cd ../
11、amr-wb
https://code.google.com/p/ostube/downloads/detail?name=amrwb-10.0.0.0.tar.bz2&can=2&q=amrwb (该地址可以下载)
tar -jxvf amrwb-10.0.0.0.tar.bz2
cd amrwb-10.0.0.0
./configure
make
make出现如下的报错：
make ./26204-a00_ANSI-C_source_code.zip
make[1]: Entering directory `/software/amrwb-10.0.0.0'
cd . && /usr/bin/wget -N http://ostube.googlecode.com/files/26204-a00.zip

根据报错信息，解决办法：
https://code.google.com/p/ostube/downloads/detail?name=26204-a00.zip&can=2&q=26204-a00.zip 通过这个地址下载26204-a00.zip压缩包传到跟make同一级目录；
继续安装
make
make install
cd ../
12、最后一步，安装ffmpeg
wget http://www.ffmpeg.org/releases/ffmpeg-2.5.3.tar.gz
./configure --enable-shared --prefix=/usr/local/ffmpeg2 --enable-libmp3lame --enable-libvorbis --enable-gpl --enable-version3 --enable-nonfree --enable-pthreads --enable-libfaac --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libx264 --enable-libxvid --enable-postproc --enable-ffserver --enable-ffplay
编译这条语句出错，去掉三个参数，可以成功编译；
./configure --enable-shared --prefix=/usr/local/ffmpeg2 --enable-libmp3lame --enable-libvorbis --enable-gpl --enable-version3 --enable-nonfree --enable-pthreads --enable-libfaac --enable-libxvid --enable-postproc --enable-ffserver --enable-ffplay
才可以编译通过
make
make install
测试报错：
[root@C21318 ffmpeg-2.5.3]# /usr/local/ffmpeg2/bin/ffmpeg --help
/usr/local/ffmpeg2/bin/ffmpeg: error while loading shared libraries: libavdevice.so.56: cannot open shared object file: No such file or directory
