CentOS 6.2下编译mpeg4ip

一、环境1、操作系统版本CentOS 6.2 64位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/Linux2、mpeg4ip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 为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 errorssys_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 typetype_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 在320行去掉括号内的Void，如图所示：2.4 报错内容： cc1: warnings being treated as errorsconfig.c: In function "enter_chn":config.c:636: error: array subscript is above array boundsconfig.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c和c99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）#endif2.6 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 scopeffmpeg.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在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 好，编译成功，make install 即可使用。三、安装使用1、安装make install2、使用mp4livegcc命令行详解CentOS 6.2编译安装PHP5.4.0相关资讯 CentOS教程 mpeg4ip
