CentOS6.2下编译mpeg4ip

一、环境

1、操作系统版本

CentOS 6.2 64

uname -a的输出:

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

2mpeg4ip版本

版本:1.6.1

下载链接:

http://people.freebsd.org/~ahze/distfiles/mpeg4ip-1.6.1.tar.gz 

 

二、编译 

1、编译mpeg4ip需要的库 

首先安装libtool库,命令如下: 

yum install libtool 

然后进入到mpeg4ip的目录,运行./bootstrap进行配置,如果出错,是因为bash版本及名称的问题,修改bootstrap文件中第一行,改sh bash.或运行 bash ./bootstrap。 

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

 安装相应库: 

yum install ffmpeg-devel xvidcore-devel twolame-devel x264-devel 

编译:make 

2、编译中的错误处理 

2.1 报错内容:  

In file included from config_opts.cpp:1:
/include/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*)'

解决办法:

vi include/mpeg4ip.h 

注释掉函数声明,如下所示:

2.2 报错内容: 

cc1plus: warnings being treated as errors
sys_decoder_blkdec.cpp:190: error: suggest parentheses around '&&' within '||'
sys_decoder_blkdec.cpp:205: error: suggest parentheses around '&&' within '||'

 如图所示:

解决办法:

vi common/video/iso-mpeg4/src/Makefile 

去掉Werror 

vi命令: %s/-Werror//

2.3 报错内容: 

type_basic.cpp:320: error: '<anonymous>' has incomplete type
type_basic.cpp:320: error: invalid use of 'Void'
type_basic.cpp:320: error: prototype for 'Void CMotionVector::setToZero(<type error>)' does not match any in class 'CMotionVector'
./../include/basic.hpp:441: error: candidate is: Void CMotionVector::setToZero()

解决办法: 

vi common/video/iso-mpeg4/src/type_basic.cpp 

320行去掉括号内的Void,如图所示:

2.4 报错内容:  

cc1: warnings being treated as errors
config.c: In function 'enter_chn':
config.c:636: error: array subscript is above array bounds
config.c:637: error: array subscript is above array bounds

解决办法: 

vi player/lib/audio/faad/Makefile 

去掉Werror 

2.5 报错内容: 

/usr/local/include/libavutil/common.h: In function ‘int32_t av_clipl_int32(int64_t)’:
/usr/local/include/libavutil/common.h:154: error: ‘UINT64_C’ was not declared in this scope
...

解决办法: 

涉及到标准cc99的问题,在出问题的文件中加上下面三句话就好了 

#ifndef UINT64_C
#define UINT64_C(value)__CONCAT(value,ULL)
#endif

2.6 报错内容: 

In file included from ffmpeg.cpp:26:
ffmpeg.h:29:28: error: ffmpeg/avcodec.h: No such file or directory
...

 解决办法:

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。

vi player/plugin/audio/ffmpeg/ffmpeg.h

在第30行进行修改,替换成完整路径:

#include <ffmpeg-spice/libavcodec/avcodec.h> 

2.7 报错内容: 

ffmpeg.cpp: In function 'codec_data_t* ffmpeg_create(const char*, const char*, int, int, format_list_t*, audio_info_t*, const uint8_t*, uint32_t, audio_vft_t*, void*)':
ffmpeg.cpp:180: error: 'AVCODEC_MAX_AUDIO_FRAME_SIZE' was not declared in this scope
ffmpeg.cpp: In function 'int ffmpeg_decode(codec_data_t*, frame_timestamp_t*, int, int*, uint8_t*, uint32_t, void*)':

 解决办法:

vi /usr/include/ffmpeg-spice/libavcodec/avcodec.h

查找 AVCODEC_MAX_AUDIO_FRAME_SIZE,得到如下结果: 

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

vi player/plugin/audio/ffmpeg/ffmpeg.h

添加如下内容:

#define AVCODEC_MAX_AUDIO_FRAME_SIZE 192000 

2.8 报错内容: 

media_utils.cpp: In function 'int create_media_for_iptv(CPlayerSession*, const char*, int, control_callback_vft_t*)':
media_utils.cpp:613: error: invalid conversion from 'const char*' to 'char*'

 解决办法:

vi player/src/media_utils.cpp

613行,对name变量进行强制类型转换,如图所示:

 2.9 报错内容:

../server/mp4live/video_util_resize.h:93: error: conflicting declaration 'uint8_t* fV'
../server/mp4live/video_util_resize.h:91: error: 'fV' has a previous declaration as 'const uint8_t* fV'
../server/mp4live/video_util_resize.h:94: error: redefinition of 'uint32_t tvStride'
../server/mp4live/video_util_resize.h:94: error: 'uint32_t tvStride' previously declared here
解决办法:
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OK了。这是我修改:
void CopyYuv(const uint8_t *fY, const uint8_t *fU, const uint8_t *fV,
             uint32_t fyStride, uint32_t fuStride, uint32_t fvStride2,
             uint8_t *tY, uint8_t *tU, uint8_t *fV2,
             uint32_t tyStride, uint32_t tvStride, uint32_t tvStride2,
             uint32_t w, uint32_t h); 
2.10 报错内容:
video_ffmpeg.cpp:124: error: 'struct AVCodecContext' has no member named 'frame_rate'
video_ffmpeg.cpp:125: error: 'struct AVCodecContext' has no member named 'frame_rate_base'
video_ffmpeg.cpp:136: error: 'struct AVCodecContext' has no member named 'aspect_ratio'
解决办法:
这几个错误影响不大,就直接注释掉了,我主要用mp4live 
vi server/mp4live/video_ffmpeg.cpp 

好,编译成功,make install 即可使用。

三、安装使用

1、安装

make install

2、使用mp4live
