配置PKG CONFIG路径，主要是安装libass时会出现
Package libass was not found in the pkg-config search path.
Perhaps you should add the directory containing `libass.pc‘
to the PKG_CONFIG_PATH environment variable
的错误。

[root@localhost ffmpeg]#vi /etc/profile
添加下面几行:

PKG_CONFIG=/usr/bin/pkg-config
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL JAVA_HOME JRE_HOME CLASSPATH PKG_CONFIG PKG_CONFIG_PATH #注:后面两个变量是新添加的

保存退出。
[root@localhost ffmpeg]#source /etc/profile
[root@localhost ffmpeg]#cd faac-1.28
[root@localhost ffmpeg]#./bootstrap
[root@localhost ffmpeg]#./configure --prefix=/usr/local/ --enable-shared
[root@localhost ffmpeg]#make && make install

出现错误： g++: not found
解决方法：yum install gcc+ gcc-c++
make
出现错误：mpeg4ip.h:126: error: new declaration ‘char* strcasestr(const char*, const char*)’
解决方法：vim faac-1.28/common/mp4v2/mpeg4ip.h

从123行开始修改此文件mpeg4ip.h，到129行结束。
修改前：
#ifdef __cplusplus
extern "C" {
#endif
char *strcasestr(const char *haystack, const char *needle);
#ifdef __cplusplus
}
#endif

修改后：
#ifdef __cplusplus
extern "C++" {
#endif
const char *strcasestr(const char *haystack, const char *needle);
#ifdef __cplusplus
}
#endif
接着安装

[root@localhost ffmpeg]#make && make install
[root@localhost ffmpeg]#cd ..

[root@localhost ffmpeg]#cd lame-3.99.5
[root@localhost ffmpeg]#./configure --prefix=/usr/local/ --enable-shared

[root@localhost ffmpeg]#cd ..

[root@localhost ffmpeg]#cd libtheora-1.1.1
[root@localhost ffmpeg]#./configure --prefix=/usr/local/ --enable-shared

*** Could not run Ogg test program, checking why...
*** The test program compiled, but did not run. This usually means
*** that the run-time linker is not finding Ogg or finding the wrong
*** version of Ogg. If it is not finding Ogg, you‘ll need to set your
*** LD_LIBRARY_PATH environment variable, or edit /etc/ld.so.conf to point
*** to the installed location  Also, make sure you have run ldconfig if that
*** is required on your system
***
*** If you have an old version installed, it is best to remove it, although
*** you may also be able to get things to work by modifying LD_LIBRARY_PATH
configure: error:
    libogg is required to build this package!
    please see http://www.xiph.org/ for how to
    obtain a copy.
    
明明安装了ogg但theora却认为咱们没安装。原因在哪里，当然是动态库的查找路径了，
我的解决办法是在 /etc/ld.so.conf.d/目录下创建一个名为local-libraries.conf的文件，内容很简单，只有一行：
/usr/local/lib

然后执行ldconfig -v    
[root@localhost ffmpeg]#./configure --prefix=/usr/local/ --enable-shared

执行下面的配置命令
