目标机器是内核版本2.63.2的,但是ffmpeg官网提供的静态编译是基于3.2.0的,所以需要自己编译。

以下步骤参考:CompilationGuide/Centos – FFmpeg,只在少数步骤有一点调整。原文没有编译libtheora,这里添加上了。

编译机器:

1
2
3
4
5
$ cat /etc/issue
CentOS release 6.9 (Final)
$ uname -a
Linux ip-172024-133091.test.nd 2.6.32-696.10.1.el6.x86_64 #1 SMP Tue Aug 22 18:51:35 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

安装编译工具:

1
yum install autoconf automake bzip2 cmake freetype-devel gcc gcc-c++ git libtool make mercurial pkgconfig zlib-devel

新建源码目录:

1
mkdir ~/ffmpeg_sources

安装NASM:

cd ~/ffmpeg_sources
curl -O -L http://www.nasm.us/pub/nasm/releasebuilds/2.13.02/nasm-2.13.02.tar.bz2
tar xjvf nasm-2.13.02.tar.bz2
cd nasm-2.13.02
./autogen.sh
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin"
make
make install

安装Yasm:

cd ~/ffmpeg_sources
curl -O -L http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar xzvf yasm-1.3.0.tar.gz
cd yasm-1.3.0
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin"
make
make install

安装libx264转码器:

1

cd ~/ffmpeg_sources
git clone --depth 1 http://git.videolan.org/git/x264
cd x264
git checkout stable
PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static
make
make install

如果不切换分支到stable分支,make提示错误:

1
2
filters/video/resize.c: In function ‘pick_closest_supported_csp’:
filters/video/resize.c:215: error: ‘AVComponentDescriptor’ has no member named ‘depth’

安装libx265编码器:

1
2
3
4
5
6
cd ~/ffmpeg_sources
hg clone https://bitbucket.org/multicoreware/x265
cd ~/ffmpeg_sources/x265/build/linux
cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$HOME/ffmpeg_build" -DENABLE_SHARED:bool=off ../../source
make
make install

安装aac编码器:

1
2
3
4
5
6
7
cd ~/ffmpeg_sources
git clone --depth 1 https://github.com/mstorsjo/fdk-aac
cd fdk-aac
autoreconf -fiv
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make
make install

安装libmp3lame编码器:

1

5
6
7
cd ~/ffmpeg_sources
curl -O -L http://downloads.sourceforge.net/project/lame/lame/3.100/lame-3.100.tar.gz
tar xzvf lame-3.100.tar.gz
cd lame-3.100
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --disable-shared --enable-nasm
make
make install

安装libopus编码器:

1
2
3
4
5
6
7
cd ~/ffmpeg_sources
curl -O -L https://archive.mozilla.org/pub/opus/opus-1.2.1.tar.gz
tar xzvf opus-1.2.1.tar.gz
cd opus-1.2.1
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make
make install

安装libogg编码器:

1
2
3
4
5
6
7
cd ~/ffmpeg_sources
curl -O -L http://downloads.xiph.org/releases/ogg/libogg-1.3.3.tar.gz
tar xzvf libogg-1.3.3.tar.gz
cd libogg-1.3.3
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make
make install

安装libvorbis编码器:

cd ~/ffmpeg_sources
curl -O -L http://downloads.xiph.org/releases/vorbis/libvorbis-1.3.5.tar.gz
tar xzvf libvorbis-1.3.5.tar.gz
cd libvorbis-1.3.5
./configure --prefix="$HOME/ffmpeg_build" --with-ogg="$HOME/ffmpeg_build" --disable-shared
make
make install

安装libtheora编码器:

7
cd ~/ffmpeg_sources
curl -O -L http://downloads.xiph.org/releases/theora/libtheora-1.1.1.tar.gz
tar xzvf libtheora-1.1.1.tar.gz
cd libtheora-1.1.1
./configure --prefix="$HOME/ffmpeg_build" --with-ogg="$HOME/ffmpeg_build" --disable-shared
make
make install

安装libvpx编码器:

6
cd ~/ffmpeg_sources
git clone --depth 1 https://chromium.googlesource.com/webm/libvpx.git
cd libvpx
./configure --prefix="$HOME/ffmpeg_build" --disable-examples --disable-unit-tests --enable-vp9-highbitdepth --as=yasm
make
make install

这里遇到一个问题,就是google这个网址无法访问,找到有翻墙能力的浏览器,访问https://chromium.googlesource.com/webm/libvpx.git/+/v1.7.0,下载源码并上传到服务器

1
2
mkdir libvpx
tar xzvf libvpx.git-f80be22a1099b2a431c2796f529bb261064ec6b4.tar.gz -C libvpx

然后继续执行命令。

--enable-libx264 \
--enable-libx265 \
--enable-nonfree
make
make install
hash -r

在~/bin目录下有静态编译好的ffmpeg和ffprobe。

我把命令文件复制到其他机器上执行,提示错误:

1
./ffmpeg: error while loading shared libraries: libfreetype.so.6: cannot open shared object file: No such file or directory`

是因为freetype的依赖没有,安装即可:

1
yum install -y freetype-devel
