linux 编译ffmpeg 支持x264, x265
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 update sudo 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) ffmpeg
git 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) x265
hg 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.gz tar 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 yasm
cd yasm-1.3.0 ./configure --prefix="$HOME/" make make install
或者安装已有的库(yasm version ≥ 1.3.0)
sudo apt-get install yasm
3.2 x264
在配置ffmpeg config时须要增加--enable-gpl和--enable-libx264
cd x264* ./configure --prefix="$FFMPEG_PATH" --enable-shared --enable-static make -j4 make install make clean或者安装已有的库(yasm version ≥ 1.3.0)
sudo apt-get install libx264-dev
3.3 x265
cd x265/build/linux cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$FFMPEG_PATH" -DENABLE_SHARED:bool=off ../../source make -j4 make install make clean </tt></span>
3.4 aac
在配置ffmpeg config时须要增加--enable-libfdk_aac(假设开启--enable-gpl同一时候须要开启--enable-nonfree )
PKG_CONFIG_PATH="$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.conf
vim /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
