linux上安装ffmpeg

windows版本比较容易，可以去看看月小升之前的文章点这里

Linux
安装环境CentOS
下载tar.bz2安装包
tar -xvf XX.tar.bz2

yasm/nasm not found or too old. Use --disable-yasm for a crippled build.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.

http://yasm.tortall.net/Download.html 下载yasm

tar -zxvf yasm.tar.gz
./configure
make
make install

再来
ffmpeg下面

./configure

安装完毕，发现无法将amr转成MP3

./ffmpeg -i x.amr x.mp3

./configure --enable-libmp3lame

少这个libmp3lame

# wget http://downloads.sourceforge.net/lame/lame-3.97.tar.gz
# tar xzf lame-3.97.tar.gz
# cd lame-3.97 
# ./configure 
# make 
# make install

ERROR: libmp3lame >= 3.98.3 not found

http://downloads.sourceforge.net/lame/去这里找最新的版本，下载一个。

我下到的是lame-3.99.5.tar.gz

# ./configure 
# make 
# make install

./ffmpeg -i x.amr x.mp3


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

发生这个我们这样弄

编辑/etc/ld.so.conf文件加入如下内容

/usr/local/lib

保存退出后执行ldconfig命令

大功告成。

你缺少的库，可能都在下面了

FFmpeg软件只是个解码编码软件，如果支持多种格式必须先安装好对应的库，下面就说下我装的库：
1. 安装faad2

# wget http://downloads.sourceforge.net/faac/faad2-2.6.1.tar.gz
# tar xvfz faad2-2.6.1.tar.gz
# cd faad2
# ./bootstrap
# ./configure
# make
# make install
2. 安装liba52

# wget http://liba52.sourceforge.net/files/a52dec-0.7.4.tar.gz
# tar xvfz a52dec-0.7.4.tar.gz
# cd a52dec-0.7.4
# ./configure
# make
# make install
3. 安装libdirac

# wget http://downloads.sourceforge.net/dirac/dirac-0.10.0.tar.gz
# tar xvfz dirac-0.10.0.tar.gz
# cd dirac-0.10.0
# ./configure
# make
# make install
4. 安装faac2

# wget http://downloads.sourceforge.net/faac/faac-1.26.tar.gz
# tar xvfz faac-1.26.tar.gz
# cd faac
# ./bootstrap
# ./configure
# make
# make install
5. 安装libamrnb

# wget http://ftp.penguin.cz/pub/users/utx/amr/amrnb-7.0.0.2.tar.bz2
# tar xvfj amrnb-7.0.0.2.tar.bz2
# cd amrnb-7.0.0.2
# ./configure
# make
# make install
6. 安装libamrwb

# wget http://ftp.penguin.cz/pub/users/utx/amr/amrwb-7.0.0.3.tar.bz2
# tar xvfj amrwb-7.0.0.3.tar.bz2
# cd amrwb-7.0.0.3
# ./configure
# make
# make install
7. 安装libmp3lame

# wget http://downloads.sourceforge.net/lame/lame-3.97.tar.gz
# tar xzf lame-3.97.tar.gz
# cd lame-3.97
# ./configure
# make
# make install
8. 安装libx264
此软件包需要用git来获取，所以要先安装git:

# wget http://kernel.org/pub/software/scm/git/git-1.6.2.tar.gz (地址要确认)
# tar zxvf git-1.6.2.tar.gz
# cd git-1.6.2
# ./configure
# make
# make install
然后安装libx264

# /usr/local/bin/git clone git://git.videolan.org/x264.git x264
# cd x264
# ./configure --enable-pthread --enable-shared --disable-asm
# make
# make install
8. 安装libnut，该软件需要用svn获取源代码，svn可以直接用yum install svn来装。先下载:

# svn co svn://svn.mplayerhq.hu/nut/src/trunk libnut
下载后代码保存在新建立的libnut目录下，对于64位Linux需要修改配置文件:

# cd libnut
# vi config.mak
在最后一个CFLAGS下一行增加:

CFLAGS += -fPIC
然后编译安装:

# make
# make install
9. 安装libogg

# wget http://downloads.xiph.org/releases/ogg/libogg-1.1.3.tar.gz
# tar xvf libogg-1.1.3.tar.gz
# cd libogg-1.1.3
# ./configure
# make
# make install
10. 安装libtheora (svn获取)

# svn co http://svn.xiph.org/trunk/theora theora
# cd theora
# ./autogen.sh
# ./configure
# make
# make install
11. 安装libvorbis

# wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.2.0.tar.gz
# tar xvfz libvorbis-1.2.0.tar.gz
# cd libvorbis-1.2.0
# ./configure
# make
# make install
12. 安装libxvid

# wget http://downloads.xvid.org/downloads/xvidcore-1.2.1.tar.gz
# tar xvf xvidcore-1.2.1.tar.gz
# cd xvidcore-1.2.1/build/generic
# ./bootstrap.sh
# ./configure --disable-assembly
# make
# make install

上面的媒体支持库安装完后，可以设置下环境准备编译FFmpeg了！
13. 修改环境变量

# vi /etc/ld.so.conf
在文件末增加一行:

/usr/local/lib
然后生效之:

# ldconfig
14. 安装FFmpeg
可以通过svn获取，不过文件比较大，所以特别慢:

# svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
# cd ffmpeg
也可以自己下载:

# http://www.ffmpeg.org/releases/ffmpeg-0.5.tar.bz2
# bzip2 -d ffmpeg-0.5.tar.bz2
# tar -xf ffmpeg-0.5.tar
# cd ffmpeg-0.5
编译(64位系统需要设置PKG_CONFIG_PATH参数):

# export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig CFLAGS="-fPIC -m64"
# ./configure --enable-shared \
--enable-gpl \
--enable-nonfree \
--enable-postproc \
--enable-avfilter \
--enable-avfilter-lavf \
--enable-pthreads \
--enable-libamr-nb \
--enable-libamr-wb \
--enable-libdirac \
--enable-libfaac \
--enable-libfaad \
--enable-libfaadbin \
--enable-libmp3lame \
--enable-libnut \
--enable-libtheora \
--enable-libvorbis \
--enable-libx264 \
--enable-libxvid \
--enable-decoder=libx264 \
--enable-encoder=libx264
# make
# make install

14. 可能出现的错误:

/usr/include/linux/videodev.h:56: error: syntax error before "ulong"
/usr/include/linux/videodev.h:72: error: syntax error before '}' token
libavdevice/v4l.c: In function `grab_read_header':
libavdevice/v4l.c:75: error: storage size of 'tuner' isn't known
libavdevice/v4l.c:133: error: invalid application of `sizeof' to incomplete type `video_tuner'
libavdevice/v4l.c:140: error: invalid application of `sizeof' to incomplete type `video_tuner'
libavdevice/v4l.c:75: warning: unused variable `tuner'
这可能是源代码videodev.h不是针对次版本Linux写的，标准C没有ulong类型，所以要改成unsigned long

15. 运行ffmpeg -formats，可能出的错误:

ffmpeg: error while loading shared libraries: libavfilter.so.0: cannot open shared object file: No such file or directory
这事没有设置环境路径造成了，增加一个ffmpeg.conf配置文件:

# cd /etc/ld.so.conf.d
# vi ffmpeg.conf
在文件内写上:

/usr/local/lib
然后确认生效:

# ldconfig
16. 其他:
本文中没有提到libgsm的安装，请参考下面的资料。
