一、环境@H_404_4@@H_404_4@@H_404_4@
1@H_404_4@、操作系统版本@H_404_4@@H_404_4@@H_404_4@
CentOS 6.2 64@H_404_4@位@H_404_4@@H_404_4@@H_404_4@
uname -a@H_404_4@的输出：@H_404_4@@H_404_4@@H_404_4@
Linux localhost.localdomain 2.6.32-220.17.1.el6.x86_64 #1 SMP Wed May 16 00:01:37 BST 2012 x86_64 x86_64 x86_64 GNU/Linux@H_404_4@@H_404_4@
2@H_404_4@、@H_404_4@@H_404_4@mpeg4ip@H_404_4@版本@H_404_4@@H_404_4@@H_404_4@

二、编译@H_404_4@@H_404_4@@H_404_4@
1@H_404_4@、编译mpeg4ip@H_404_4@需要的库
首先安装@H_404_4@libtool@H_404_4@@H_404_4@库，命令如下：@H_404_4@@H_404_4@
yum install libtool@H_404_4@
然后进入到mpeg4ip@H_404_4@的目录，运行./bootstrap@H_404_4@进行配置，如果出错，是因为bash@H_404_4@版本及名称的问题，修改bootstrap@H_404_4@文件中第一行，改sh @H_404_4@为bash.@H_404_4@或运行 bash ./bootstrap@H_404_4@。
提示如下：
*** ffmpeg encoder is not installed *** xvid encoder is not installed *** x264 encoder is not installed *** lame encoder is not installed *** faac encoder is not installed *** twolame encoder is not installed@H_404_4@
yum install ffmpeg-devel xvidcore-devel twolame-devel x264-devel@H_404_4@@H_404_4@@H_404_4@
编译：@H_404_4@@H_404_4@make@H_404_4@
2@H_404_4@@H_404_4@、编译中的错误处理@H_404_4@@H_404_4@
2.1 @H_404_4@@H_404_4@报错内容：@H_404_4@@H_404_4@

vi include/mpeg4ip.h@H_404_4@@H_404_4@@H_404_4@
注释掉函数声明，如下所示：@H_404_4@@H_404_4@

如图所示：
vi common/video/iso-mpeg4/src/Makefile@H_404_4@
去掉Werror@H_404_4@
vi@H_404_4@命令：@H_404_4@%s/-Werror//@H_404_4@

vi common/video/iso-mpeg4/src/type_basic.cpp@H_404_4@
在@H_404_4@320@H_404_4@行去掉括号内的@H_404_4@Void@H_404_4@，如图所示：@H_404_4@
cc1: warnings being treated as errors config.c: In function 'enter_chn': config.c:@H_404_4@636: error: array subscript is above array bounds config.c:@H_404_4@637: error: array subscript is above array bounds

涉及到标准c@H_404_4@和c99@H_404_4@的问题，在出问题的文件中加上下面三句话就好了
2.6 @H_404_4@报错内容：@H_404_4@@H_404_4@@H_404_4@
In file included from ffmpeg.cpp:26: ffmpeg.h:@H_404_4@29:28: error: ffmpeg/avcodec.h: No such file or directory ...@H_404_4@
版本遗留问题，修改下路径就行了。其实这是一类问题，接下来还会遇到好多次，以这个为例展例下，其它的照此修改就OK了。@H_404_4@
vi player/plugin/audio/ffmpeg/ffmpeg.h@H_404_4@
在第@H_404_4@30@H_404_4@@H_404_4@行进行修改，替换成完整路径：@H_404_4@
#include <ffmpeg-spice/libavcodec/avcodec.h>@H_404_4@

复制其值到文件@H_404_4@player/plugin/audio/ffmpeg/ffmpeg.h@H_404_4@@H_404_4@，并把@H_404_4@Q@H_404_4@@H_404_4@去掉：@H_404_4@

在@H_404_4@613@H_404_4@@H_404_4@行，对@H_404_4@name@H_404_4@@H_404_4@变量进行强制类型转换，如图所示：@H_404_4@

@H_404_4@这个就是函数声明的时候变量重名了，把名字修改的不同就@H_404_4@OK@H_404_4@@H_404_4@了。@H_404_4@这是我修改：@H_404_4@

@H_404_4@
好，编译成功，@H_404_4@make install @H_404_4@@H_404_4@即可使用。@H_404_4@
三、安装使用@H_404_4@
1@H_404_4@@H_404_4@、安装@H_404_4@
make install@H_404_4@
