1. 前言
本教程涉及的ffmpeg, x264, x265
2. 环境依赖
2.1 删除系统中安装的ffmpeg等库sudo apt-get –purge remove ffmpeg mplayer x264 x265
2.2 安装依赖库sudo apt-get updatesudo apt-get -y –force-yes install autoconf automake build-essential libass-dev libfreetype6-dev libgpac-dev \ libsdl1.2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev \ libxcb-xfixes0-dev pkg-config texi2html zlib1g-dev
注: server版本号可忽略 libsdl1.2-dev libva-dev libvdpau-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev
2.3 下载源码
(1) ffmpeggit clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
(2) x264<pre name=”code” class=”plain”><pre name=”code” class=”plain”>git clone git://git.videolan.org/x264.git
(3) x265hg clone https://bitbucket.org/multicoreware/x265
(4) yasm yasm 是x86平台的一个汇编优化器, 可以加快ffmpeg x264的编译wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gztar xzvf yasm-1.3.0.tar.gz
3. 编译
3.1 配置编译输出文件夹export FFMPEG_PATH=”YOUR_PATH”export PATH=”$FFMPEG_PATH/bin:$PATH”比如我输出文件夹为$HOME/ffmpeg_2.6.3/build_out 那么:export FFMPEG_PATH=”$HOME/ffmpeg_2.6.3/build_out”
3.1 yasmcd yasm-1.3.0./configure –prefix=”$HOME/” makemake install
或者安装已有的库(yasm version ≥ 1.3.0)sudo apt-get install yasm
3.2 x264
在配置ffmpeg config时须要增加–enable-gpl和–enable-libx264cd x264*./configure –prefix=”$FFMPEG_PATH” –enable-shared –enable-staticmake -j4make installmake clean或者安装已有的库(yasm version ≥ 1.3.0)sudo apt-get install libx264-dev
3.3 x265cd x265/build/linuxcmake -G “Unix Makefiles” -DCMAKE_INSTALL_PREFIX=”$FFMPEG_PATH” -DENABLE_SHARED:bool=off ../../sourcemake -j4make installmake clean</tt></span>
3.4 aac
在配置ffmpeg config时须要增加–enable-libfdk_aac(假设开启–enable-gpl同一时候须要开启–enable-nonfree )PKG_CONFIG_PATH=”$FFMPEG_PATH/lib/pkgconfig” ./configure \ –prefix=”$FFMPEG_PATH” \ –pkg-config-flags=”–static” \ –extra-cflags=”-I$FFMPEG_PATH/include” \ –extra-ldflags=”-L$FFMPEG_PATH/lib” \ –enable-gpl \ –enable-libass \ –enable-libfaac \ –enable-libfreetype \ –enable-libmp3lame \ –enable-libtheora \ –enable-libvorbis \ –enable-libx264 \ –enable-libx265 \ –enable-nonfree \ –enable-shared \ –enable-postproc \ –enable-x11grab \ –enable-bzlib \ –enable-libxvid \ –enable-zlib \ –disable-debug
4. 将ffmpeg加入到环境变量
4.1 将ffmpeg加入到环境变量vim ~/.bashrc在最后加入
export FFMPEG_PATH=”/home/guohe/workspace/ffmpeg_2.6.3/build_out”export PATH=”$FFMPEG_PATH/bin:$PATH”
4.2 加入链接库
编译完毕之后调用 ffmpeg 会出现 error while loading shared libraries: xxx
解决这样的问题有2中方法:
(1) 改动/etc/ld.so.confvim /etc/ld.so.conf
在最后加入$FFMPEG_PATH/lib
然后运行sudo ldconfig
(2) 改动LD_LIBRARY_PATH
vim ~/.bashrc在最后加入export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$FFMPEG_PATH/ib
