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 (这个需要翻墙才能下载)

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]: *** [all-recursive] Error 1

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，需要翻墙才可以下载；

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

--2015-02-08 20:44:09-- http://ostube.googlecode.com/files/26204-a00.zip

Resolving ostube.googlecode.com... 74.125.203.82, 2404:6800:4008:c07::52

Connecting to ostube.googlecode.com|74.125.203.82|:80... ^Cmake[1]: *** [26204-a00.zip] Interrupt

make: *** [readme.txt] Interrupt

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
