以前用Ubuntu自带的源在线安装ffmpeg过，不过觉得更新比较麻烦，而且每次安装完要收工锁定关键的安装包，要不系统自动升级时会覆盖你的安装，相当不习惯！所以，个人认为还是用源代码安装比较好。 1. 先确认某些解码包没有安装，例如H264的，如果安装了要卸载掉： sudo apt-get purge ffmpeg x264 libx264-dev 2. 开始安装： 1) 安装zlib (可以去www.找最新版本装) wget http://www./zlib-1.2.3.tar.gz tar -zxf zlib-1.2.3.tar.gz cd zlib-1.2.3 make sudo make install 2) 安装faad2 wget http://downloads./faac/faad2-2.7.tar.gz tar xvfz faad2-2.6.1.tar.gz cd faad2 ./configure make sudo make install 3) 安装liba52 wget http://liba52./files/a52dec-0.7.4.tar.gz tar xvfz a52dec-0.7.4.tar.gz cd a52dec-0.7.4 ./configure make sudo make install 4) 安装libdirac wget http://downloads./dirac/dirac-1.0.2.tar.gz tar xvfz dirac-1.0.2.tar.gz cd dirac-1.0.2 ./configure make sudo make install 5) 安装faac2 wget http://downloads./faac/faac-1.28.tar.gz tar xvfz faac-1.26.tar.gz cd faac ./bootstrap ./configure make make install 6) 安装libgsm wget http://kbs.cs./~jutta/gsm/gsm-1.0.13.tar.gz tar xvfz gsm-1.0.13.tar.gz cd gsm-1.0-pl13 make sudo make install 7) 安装amrnb (官网：http://www./~utx/amr) wget http://ftp./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 sudo make install 8) 安装amrwb wget http://ftp./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 sudo make install 9) 安装libmp3lame (官网 : http:///projects/lame) wget http://downloads./lame/lame-398-2.tar.gz tar xzf lame-3.97.tar.gz cd lame-3.97 ./configure make sudo make install 10) 安装libnut (svn获取源代码) Library and tools to create NUT multimedia files svn co svn://svn.mplayerhq.hu/nut/src/trunk libnut cd libnut make sudo make install 11) 安装libogg wget http://downloads./releases/ogg/libogg-1.1.4.tar.gz tar xvf libogg-1.1.4.tar.gz cd libogg-1.1.4 ./configure make sudo make install 13) 安装libtheora (svn获取) svn co http://svn./trunk/theora theora cd theora ./autogen.sh ./configure make sudo make install 14) 安装libvorbis wget http://downloads./releases/vorbis/libvorbis-1.2.3.tar.gz tar xvfz libvorbis-1.2.3.tar.gz cd libvorbis-1.2.3 ./configure make sudo make install 15) 安装libxvid wget http://downloads./downloads/xvidcore-1.2.2.tar.gz tar xvf xvidcore-1.2.2.tar.gz cd xvidcore-1.2.2/build/generic ./configure --enable-assembly make sudo make install 16) 安装x264 需要先安装yasm wget http://www./projects/yasm/releases/yasm-0.8.0.tar.gz tar -xzf yasm-0.8.0.tar.gz cd yasm-0.8.0 ./configure make sudo make install 获取最新版本的x264并编译安装，我们在这里通过git命令获取： cd ~/ git clone git://git.videolan.org/x264.git 开始编译并安装 cd x264 ./configure --enable-pthread --enable-shared --enable-asm make sudo make install sudo ldconfig 17) 安装ffmpeg a. 下载ffmpeg wget -O ffmpeg.tar.gz "http://git./?p=ffmpeg;a=snapshot;h=124fefe867ef023a89ca4f4cc76e700342286b0d;sf=tgz" tar -xvzf ffmpeg.tar.gz cd ffmpeg b. 这个tar包版本的ffmpeg没有libswscale，所以要在ffmpeg目录下单独下载: wget -O libswscale.tar.gz "http://git./?p=libswscale;a=snapshot;h=1842e7d1cc122feea92dcd2d9a9a1adfb397aa24;sf=tgz" tar -xvzf libswscale.tar.gz c. 安装aacPlus库 它需要libtool和autoconf，所以要先装： sudo apt-get install libtool autoconf d. 然后下载安装aacPlus (official website : http:///node/17) wget http:///downloads/media/aac+/libaacplus/libaacplus-1.0.4.tar.gz tar -zxf libaacplus-1.0.4.tar.gz cd libaacplus-1.0.4 ./autogen.sh ./configure make sudo make install e. 下载并安装aacPlus补丁 wget http:///downloads/media/aac+/libaacplus-simple-sample/ffmpeg-patch/ffmpeg-aacp.diff patch -p1 < ffmpeg-aacp.diff f. 开始编译ffmpeg ./configure / --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-libgsm / --enable-libmp3lame / --enable-libnut / --enable-libtheora / --enable-libvorbis / --enable-libx264 / --enable-libxvid / --enable-decoder=libx264 / --enable-encoder=libx264 / --enable-libaacplus make sudo make install sudo ldconfig 安装完成，enjoy! |
