linux 编译ffmpeg 支持x264, x265
1. 前言
本教程涉及的ffmpeg, x264, x2652. 环境依赖
2.1 删除系统中安装的ffmpeg等库
[plain] view plain copy sudo apt-get --purge remove ffmpeg mplayer x264 x265
2.2 安装依赖库
[plain] view plain copy 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: 服务器版本可忽略
libsdl1.2-dev libva-dev libvdpau-dev libxcb1-dev
libxcb-shm0-dev libxcb-xfixes0-dev2.3 下载源代码
(1) ffmpeg
[plain] view plain copy git clone
git:///ffmpeg.git ffmpeg
(2) x264[plain] view plain copy <pre name="code"
class="plain"><pre name="code" class="plain">git clone git:///x264.git (3) x265[plain] view plain copy hg clone
https:///multicoreware/x265
(4) yasm
yasm 是x86平台的一个汇编优化器, 能够加快ffmpeg
x264的编译
[plain] view plain copy wget
/projects/yasm/releases/yasm-1.3.0.ta r.gz tar xzvf yasm-1.3.0.tar.gz
3. 编译
3.1 配置编译输出目录
[plain] view plain copy export
FFMPEG_PATH="YOUR_PATH" export
PATH="$FFMPEG_PATH/bin:$PATH" 例如我输出目录为$HOME/ffmpeg_2.6.3/build_out
那么:
[plain] view plain copy export
FFMPEG_PATH="$HOME/ffmpeg_2.6.3/build_out"
3.1 yasm
[plain] view plain copy cd yasm-1.3.0 ./configure
--prefix="$HOME/" make make install
或者安装已有的库(yasm version ≥ 1.3.0)
[plain] view plain copy sudo apt-get install yasm 3.2 x264 在配置ffmpeg config时需要加入--enable-gpl和
--enable-libx264
[plain] view plain copy cd x264* ./configure
--prefix="$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)[plain] view plain copy sudo apt-get install libx264-dev 3.3 x265
[plain] view plain copy cd x265/build/linux cmake -G "Unix Makefiles"
-DCMAKE_INSTALL_PREFIX="$FFMPEG_PATH"
-DENABLE_SHARED:bool=off ../../source make -j4 make install make clean </tt></span>
3.4 aac
在配置ffmpeg config时需要加入--enable-libfdk_aac(如果
开启--enable-gpl同时需要开启--enable-nonfree ) [plain] view plain copy
PKG_CONFIG_PATH="$FFMPEG_PATH/lib/pkgconfig" ./ configure \ --prefix="$FFMPEG_PATH" \
--pkg-config-flags="--static" \
--extra-cflags="-I$FFMPEG_PATH/include" \
--extra-ldflags="-L$FFMPEG_PATH/lib" \ --enable-gpl \ --enable-libass \ --enable-libfaac \
--enable-libfreetype \ --enable-libmp3lame \
--enable-libtheora \ --enable-libvorbis \
--enable-libx264 \ --enable-libx265 \
--enable-nonfree \ --enable-shared \
--enable-postproc \ --enable-x11grab \
--enable-bzlib \ --enable-libxvid \ --enable-zlib \
--disable-debug
4. 将ffmpeg添加到环境变量
4.1 将ffmpeg添加到环境变量
[plain] view plain copy vim ~/.bashrc 在最后添加[plain] view plain copy export
FFMPEG_PATH="/home/guohe/workspace/ffmpeg_2.6.3/ build_out" export PATH="$FFMPEG_PATH/bin:$PATH"
4.2 添加链接库编译完成之后调用ffmpeg 会出现error
while loading shared libraries: xxx
解决这种问题有2中方法:
(1) 修改/etc/ld.so.conf
[plain] view plain copy vim /etc/ld.so.conf
在最后添加[plain] view plain copy $FFMPEG_PATH/lib
然后执行
[plain] view plain copy sudo ldconfig (2) 修改
LD_LIBRARY_PATH
[plain] view plain copy vim ~/.bashrc 在最后添加[plain] view plain copy export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$FFMPEG_P ATH/ib。
