FFmpeg是一套可以用来记录、转换数字音频、视频,并能将其转化为流的开源计算机程序,下面我们来给各位介绍在linux系统中ffmpeg安装配置步骤,有需要的可以和小编来看看具体步骤如下. http://ffmpeg.org/download.html windows版本比较容易. Linux,安装环境CentOS,下载tar.bz2安装包. tar -xvf XX.tar.bz2 yasm/nasm not found or too old. Use –disable-yasm for a crippled build. If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file “config.log” produced by configure as this will help solve the problem. http://yasm.tortall.net/Download.html 下载yasm tar -zxvf yasm.tar.gz ./configure make make install 再来,ffmpeg下面 ./configure 安装完毕,发现无法将amr转成MP3. ./ffmpeg -i x.amr x.mp3 ./configure –enable-libmp3lame 少这个libmp3lame: # wget http://downloads.sourceforge.net/lame/lame-3.97.tar.gz # tar xzf lame-3.97.tar.gz # cd lame-3.97 # ./configure # make # make install ERROR: libmp3lame >= 3.98.3 not found http://downloads.sourceforge.net/lame/去这里找最新的版本，下载一个。 我下到的是lame-3.99.5.tar.gz # ./configure # make # make install ./ffmpeg -i x.amr x.mp3 ffmpeg: error while loading shared libraries: libmp3lame.so.0: cannot open shared object file: No such file or directory 发生这个我们这样弄 编辑/etc/ld.so.conf文件加入如下内容: /usr/local/lib 保存退出后执行ldconfig命令,大功告成,你缺少的库,可能都在下面了,FFmpeg软件只是个解码编码软件,如果支持多种格式必须先安装好对应的库,下面就说下我装的库: 1.安装libamrnb # wget http://ftp.penguin.cz/pub/users/utx/amr/amrnb-7.0.0.2.tar.bz2 # tar xvfj amrnb-7.0.0.2.tar.bz2 # cd amrnb-7.0.0.2 # ./configure # make # make install 2.安装libamrwb # wget http://ftp.penguin.cz/pub/users/utx/amr/amrwb-7.0.0.3.tar.bz2 # tar xvfj amrwb-7.0.0.3.tar.bz2 # cd amrwb-7.0.0.3 # ./configure # make # make install 3.安装libmp3lame # wget http://downloads.sourceforge.net/lame/lame-3.97.tar.gz # tar xzf lame-3.97.tar.gz # cd lame-3.97 # ./configure # make # make install 4.安装faad2 # wget http://downloads.sourceforge.net/faac/faad2-2.6.1.tar.gz # tar xvfz faad2-2.6.1.tar.gz # cd faad2 # ./bootstrap # ./configure # make # make install 5安装liba52 # wget http://liba52.sourceforge.net/files/a52dec-0.7.4.tar.gz # tar xvfz a52dec-0.7.4.tar.gz # cd a52dec-0.7.4 # ./configure # make # make install 6.安装libdirac # wget http://downloads.sourceforge.net/dirac/dirac-0.10.0.tar.gz # tar xvfz dirac-0.10.0.tar.gz # cd dirac-0.10.0 # ./configure # make # make install 7.安装faac2 # wget http://downloads.sourceforge.net/faac/faac-1.26.tar.gz # tar xvfz faac-1.26.tar.gz # cd faac # ./bootstrap # ./configure # make # make install 8.安装libx264 此软件包需要用git来获取,所以要先安装git: # wget http://kernel.org/pub/software/scm/git/git-1.6.2.tar.gz (地址要确认) # tar zxvf git-1.6.2.tar.gz # cd git-1.6.2 # ./configure # make # make install 然后安装libx264. # /usr/local/bin/git clone git://git.videolan.org/x264.git x264 # cd x264 # ./configure –enable-pthread –enable-shared –disable-asm # make # make install 8.安装libnut,该软件需要用svn获取源代码,svn可以直接用yum install svn来装,先下载: # svn co svn://svn.mplayerhq.hu/nut/src/trunk libnut 下载后代码保存在新建立的libnut目录下,对于64位Linux需要修改配置文件: # cd libnut # vi config.mak 在最后一个CFLAGS下一行增加:CFLAGS += -fPIC 然后编译安装: # make # make install 9.安装libogg # wget http://downloads.xiph.org/releases/ogg/libogg-1.1.3.tar.gz # tar xvf libogg-1.1.3.tar.gz # cd libogg-1.1.3 # ./configure # make # make install 10.安装libtheora(svn获取) # svn co http://svn.xiph.org/trunk/theora theora # cd theora # ./autogen.sh # ./configure # make # make install 11.安装libvorbis # wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.2.0.tar.gz # tar xvfz libvorbis-1.2.0.tar.gz # cd libvorbis-1.2.0 # ./configure # make # make install 12.安装libxvid # wget http://downloads.xvid.org/downloads/xvidcore-1.2.1.tar.gz # tar xvf xvidcore-1.2.1.tar.gz # cd xvidcore-1.2.1/build/generic # ./bootstrap.sh --phpfensi.com # ./configure –disable-assembly # make # make install 上面的媒体支持库安装完后,可以设置下环境准备编译FFmpeg了. 13.修改环境变量 # vi /etc/ld.so.conf 在文件末增加一行:/usr/local/lib 然后生效之:# ldconfig 14.安装FFmpeg 可以通过svn获取,不过文件比较大,所以特别慢: # svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg # cd ffmpeg //也可以自己下载: # http://www.ffmpeg.org/releases/ffmpeg-0.5.tar.bz2 # bzip2 -d ffmpeg-0.5.tar.bz2 # tar -xf ffmpeg-0.5.tar # cd ffmpeg-0.5 编译(64位系统需要设置PKG_CONFIG_PATH参数): # export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig CFLAGS=”-fPIC -m64″ # ./configure –enable-shared –enable-gpl –enable-nonfree –enable-postproc –enable-avfilter –enable-avfilter-lavf –enable-pthreads –enable-libamr-nb –enable-libamr-wb –enable-libdirac –enable-libfaac –enable-libfaad –enable-libfaadbin –enable-libmp3lame –enable-libnut –enable-libtheora –enable-libvorbis –enable-libx264 –enable-libxvid –enable-decoder=libx264 –enable-encoder=libx264 # make # make install 14.可能出现的错误: /usr/include/linux/videodev.h:56: error: syntax error before “ulong” /usr/include/linux/videodev.h:72: error: syntax error before ‘}’ token libavdevice/v4l.c: In function `grab_read_header’: libavdevice/v4l.c:75: error: storage size of ‘tuner’ isn’t known libavdevice/v4l.c:133: error: invalid application of `sizeof’ to incomplete type `video_tuner’ libavdevice/v4l.c:140: error: invalid application of `sizeof’ to incomplete type `video_tuner’ libavdevice/v4l.c:75: warning: unused variable `tuner’ 这可能是源代码videodev.h不是针对次版本Linux写的,标准C没有ulong类型,所以要改成unsigned long. 15.运行ffmpeg -formats,可能出的错误: ffmpeg: error while loading shared libraries:libavfilter.so.0: cannot open shared object file: No such file or directory 这事没有设置环境路径造成了,增加一个ffmpeg.conf配置文件: # cd /etc/ld.so.conf.d # vi ffmpeg.conf //在文件内写上: /usr/local/lib //然后确认生效: # ldconfig。 （编辑：PHP编程网 - 钦州站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
