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: "" has incomplete type type_basic.cpp:320: error: invalid use of "Void" type_basic.cpp:320: error: prototype for "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:)" does not match any in class "CMotionVector" ./../include/basic.hpp:441: error: candidate is: Void CMotionVector::setToZero()
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.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 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 install 2、使用mp4live E-Mail : Mike_Zhang@live.com
