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/Linux
2、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 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
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 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) #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,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*,uint8_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
#define AVCODEC_MAX_AUdio_FRAME_SIZE 192000
2.8 报错内容:
media_utils.cpp: In function 'int create_media_for_iptv(CPlayerSession*, 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
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:
voidCopyYuv(constuint8_t*fY,constuint8_t*fU,constuint8_t*fV,uint32_tfyStride,uint32_tfuStride,uint32_tfvStride2,uint8_t*tY,uint8_t*tU,uint8_t*fV2,uint32_ttyStride,uint32_ttvStride,uint32_ttvStride2,uint32_tw,uint32_th);
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'
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
