如果只需要转到flv，装mencoder和codecs就可以了，如果还需要截图或者其他功能，就要装ffmpeg和相关解码包。ffmpeg支持的格式没有前者多，但是速度比较快，参数也很简单.我现在只尝试mplayer/mencoder的安装！

需要svn--

[root@test ~]# rpm -qa|grep subversion

subversion-1.4.2-2.el5

已经有了
如果没有需要下载编译安装，编译安装的前提还要apr/apr-util安装apache的runtime模块apr和apr-util，这样才能安装svn:
http://apr.apache.org/
先装apr，再装apr-util的时候要用
–with-apr=apr源码路径

安装subversion，这样才能装接下来的软件。

wget http://subversion.tigris.org/downloads/subversion-***.tar.gz
tar zvxf subversion-***.tar.gz

cd subversion-***

./configure –with-apr=apr的源码路径
–with-apr-util=apr-util的源码路径

安装一些需要的插件

Lame

Lame is an open source MP3 encoder. MPlayer uses lame for
compressing audio into MP3 audio when encoding files from MPEG or
other sources. Lame is not required to decode MP3 audio.
http://lame.sourceforge.net/download.php
Current Versions

* The current release version of LAME is 3.97

# tar zxvf lame-3.97.tar.gz

# cd lame-3.97

# ./configure --enable-shared --prefix=/usr

这里推荐尽量装在/usr下，默认是装在/usr/local下。这样mplayer编译都能顺利的找到库文件

# make

# make install

# whereis lame

/usr/bin/lame

支持Ogg Vorbis:

as自带相应的rpm包，如下rpm包

# rpm -qa|grep libvor

libvorbis-1.1.2-3.el5.0

libvorbis-devel-1.1.2-3.el5.0

# rpm -qa|grep libogg

libogg-devel-1.1.3-3.el5

libogg-1.1.3-3.el5

支持xvid/x264，现在最流行的两种高质量的压缩格式
http://www.xvid.org/Downloads.43.0.html
# wget http://downloads.xvid.org/downloads/xvidcore-1.1.3.tar.gz
# tar zxvf xvidcore-1.1.3.tar.gz

# cd xvidcore-1.1.3

# ./configure --prefix=/usr 报错

于是查看/xvidcore-1.1.3/doc/INSTALL

# cd build/generic/

The next step allows you to configure the xvid sources.

# cd ${xvidcore}/build/generic

# ./configure

再次configure

[root@test generic]# ./configure --prefix=/usr

# make

---------------------------------------------------------------

XviD has been successfully built.

* Binaries are currently located in the '=build'
directory

* To install them on your system, you can run '#
make install'

as root.

---------------------------------------------------------------

# make install

D: /usr/lib

I: /usr/lib/libxvidcore.so.4.1

I: /usr/lib/libxvidcore.a

D: /usr/include

I: /usr/include/xvid.h

x264的获取

# wget ftp://ftp.videolan.org/pub/videolan/x264/snapshots/x264-snapshot-20080522-2245.tar.bz2
# tar -xjvf x264-snapshot-20080522-2245.tar.bz2

# cd x264-snapshot-20080522-2245

# ./configure --prefix=/usr --enable-shared

No suitable assembler found. x264 will be several
times slower.

Please install 'yasm' to get MMX/SSE optimized code.

安装mencoder需要的codecs:
http://www1.mplayerhq.hu/MPlayer/releases/codecs
[root@test ~]# wget http://www1.mplayerhq.hu/MPlayer/releases/codecs/mplayer-codecs-20061022-1.i386.rpm
[root@test ~]# rpm -ivh mplayer-codecs-20061022-1.i386.rpm

[root@test lib]# rpm -qa|grep codecs

mplayer-codecs-20061022-1

可以whereis codecs

[root@test lib]# /usr/lib/codecs/

atrc.so.6.0
drvc.so
sipr.so.6.0 tokr.so.6.0

cook.so
dspr.so.6.0 tokf.so.6.0

安装到usr/lib/codecs

下面安装mplayer/mencoder:

Downloading MPlayer from Subversion

You can also get MPlayer via Subversion. Issue the following
command to get the latest sources:

svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer

A directory named mplayer will be created in the current
directory

[root@test ~]# svn checkout svn://svn.mplayerhq.hu/mplayer/trunk
mplayer

有些慢不如直接下载tar.bz2的包
http://www1.mplayerhq.hu/MPlayer/releases/MPlayer-1.0rc2.tar.bz2
# tar -xjvf MPlayer-1.0rc2.tar.bz2

# cd MPlayer-1.0rc2

[root@test MPlayer-1.0rc2]# ./configure --prefix=/usr/local
--enable-gui --enable-largefiles --enable-gif
--enable-png --enable-jpeg --language=zh_CN
--codecsdir=/usr/lib/codecs/

[root@test MPlayer-1.0rc2]# make

[root@test MPlayer-1.0rc2]# make install

[root@test MPlayer-1.0rc2]# whereis mplayer

mplayer: /usr/local/bin/mplayer /usr/local/etc/mplayer

[root@test MPlayer-1.0rc2]# whereis mencoder

mencoder: /usr/local/bin/mencoder

# /usr/local/bin/mencoder endless_love_I.avi -o avi.flv -of lavf

测试将62M的endless_love_I.avi压成了11M 的avi.flv

说明：configure-Mplayer时提示

Checking for LIVE555 Streaming Media libraries ... no

#可以参考http://cmuch.com/article.asp?id=168

#LIVE555 provides additional support for RTP/RTCP/RTSP/SIP
multimedia streaming in MPlayer. This is useful if you plan to use
#the MPlayer-plugin for Mozilla/FireFox. (Note: Prior to Nov 2005,
LIVE555 was known as LIVE.COM)
