在执行sudo apt-get install之前执行一下sudo apt-get update; sudo apt-get upgrade。下面列的都是基于后面ffmpeg configure命令所需要安装的第三方库：

sudo apt-get install mesa-common-dev libgl1-mesa-dev libglu1-mesa-dev freeglut3-dev freeglut3
2>. Ubuntu17
ubuntu 17 里面没有libgd2-xpm、schroedinger、libshine2，libopenjpeg2等要换成libopenjp2-7，libopencv-core2.4要自己下载代码编译。libvpx1换成libvpx4。
sudo apt-get install yasm libpcrecpp0
sudo apt-get install build-essential libtool libpcre3 libpcre3-dev libssl-dev zlib1g-dev libxml2 libxml2-dev libxml2-utils libxslt1-dbg libxslt1-dev libxslt1.1 libgd2-xpm-dev libgeoip-dev

sudo apt-get install mesa-common-dev libgl1-mesa-dev libglu1-mesa-dev freeglut3-dev freeglut3 dos2unix libsdl2-dev libsdl2-2.0-0
ubuntu 17里面没有schroedinger，要添加ubuntu 16的镜像源，/etc/apt/sources.list里面加上:
deb http://cz.archive.ubuntu.com/ubuntu xenial main universe
然后更新一下：
sudo apt-get update
sudo apt-get install libschroedinger-1.0-0 libschroedinger-dev2. 安装shine
ffmpeg需要shine3，镜像服务器上没有shine3，直接下载二进制文件安装。在：
https://launchpad.net/ubuntu/zesty/amd64/libshine3/3.1.0-5
https://launchpad.net/ubuntu/artful/amd64/libshine-dev/3.1.0-5
下载libshine3_3.1.0-5_amd64.deb、libshine-dev_3.1.0-5_amd64.deb，用sudo dpkg -i命令安装。
3. 编译lame
ffmpeg-3.3.2 要求 libmp3lame >= 3.98.3，用apt-get安装的ubuntu镜像服务器上的lame版本太低，需要自己编译。从https://sourceforge.net/projects/lame/files/lame/3.99/下载lame-3.99.5.tar.gz，解压后编译：
./configure --enable-nasm; make; sudo make install4. 编译x264
从http://www.videolan.org/developers/x264.html下载最新的版本x264-snapshot。
1) 编译nasm
ubuntu镜像服务器上的nasm版本太低，先编译nasm，从http://www.linuxfromscratch.org/blfs/view/svn/general/nasm.html下载最新的版本nasm-2.13.01.tar.bz2：
./configure --enable-sections --enable-lto; make; sudo make install不要使用--enable-werror选项，此选项将警告当成错误，有几个地方会编译不过。
在某个ubuntu服务器上，make报下面的错误：
~/nasm-2.13.01/asm/parser.c:448: undefined reference to `_Static_assert’
直接注释掉出错的这行：nasm_static_assert(P_none == 0);
nasm_static_assert宏定义为static_assert，是编译时的断言，不知道为何这个版本的ubuntu版本的gcc直接将这个看成了函数调用，有可能是gcc版本差异造成的。
2) 编译x264
./configure --enable-shared --enable-static; make; sudo make installconfigure打印：
ubuntu14:~/ffmpeg/contribute/x264-snapshot$ ./configure –enable-shared –enable-static

5. 编译x265
在windows下用msys下载：
hg clone http://hg.videolan.org/x265然后拷贝到ubuntu下。编译x265需要安装cmake，前面已经安装了。ubuntu下编译：
cd build\linux; ./ make-Makefiles.bash随后会弹出字符图形界面进行配置，用回车打开了ENABLE_AGGRESSIVE_CHECKS、ENABLE_DYNAMIC_HDR10两项，然后按g键可以保存退出。
make; sudo make install但这样编译出来的x265跑不起来：
ubuntu14: x265_master/build/linux$
x265 --versionx265: error while loading shared libraries: libx265.so.121: cannot open shared object file: No such file or directory
用ldd查看库依赖：
ubuntu14: /x265_master/build/linux$ ldd
which x265 linux-vdso.so.1 => (0x00007fff6c05b000)
libx265.so.121 => not found
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f12b53f8000)
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f12b50f3000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f12b4edd000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f12b4b15000)
/lib64/ld-linux-x86-64.so.2 (0x00007f12b5646000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f12b480e000)
查看x265编译时make install的打印有– Installing: /usr/local/lib/libx265.so.121，所以此库在/usr/local/lib/下，但这个路径没有在库的搜索路径列表里面，所以找不到。如何找到库的搜索路径，可以利用LD_DEBUG 命令，LD_DEBUG 是 glibc 中的 loader 为了方便自身调试而设置的一个环境变量。通过设置这个环境变量，可以方便的看到 loader 的加载过程。
ubuntu14: x265_master/build/linux$
LD_DEBUG=help lsValid options for the LD_DEBUG environment variable are:
libs display library search paths
reloc display relocation processing
files display progress for input file
symbols display symbol table processing
bindings display information about symbol binding
versions display version dependencies
scopes display scope information
all all previous options combined
statistics display relocation statistics
unused determined unused DSOs
help display this help message and exit
To direct the debugging output into a file instead of standard output
a filename can be specified using the LD_DEBUG_OUTPUT environment variable.

x265: error while loading shared libraries: libx265.so.121: cannot open shared object file: No such file or directory
ubuntu14:~/ffmpeg/contribute/x265_master/build/linux$
解决的办法是用ldconfig命令将/usr/local/lib加到库的搜索路径列表里面：
ubuntu14: x265_master/build/linux$
cd /etc/ld.so.conf.dubuntu14:/etc/ld.so.conf.d$
lldrwxr-xr-x 2 root root 4096 68 10:44 ./
drwxr-xr-x 163 root root 12288 68 14:35 ../
-rw-rw-r– 1 root root 38 34 2014 fakeroot-x86_64-linux-gnu.conf
lrwxrwxrwx 1 root root 40 52 12:04 i386-linux-gnu_GL.conf -> /etc/alternatives/i386-linux-gnu_gl_conf
-rw-r–r– 1 root root 108 32 03:40 i686-linux-gnu.conf

-rw-r–r– 1 root root 58 32 03:23 zz_x32-biarch-compat.conf
AA@ubuntu14:/etc/ld.so.conf.d$
sudo vi usr_local_lib.conf
vi编辑usr_local_lib.conf，文件内容为/usr/local/lib。最后执行一下sudo ldconfig。
AA@ubuntu14:/etc/ld.so.conf.d$
cat usr_local_lib.conf/usr/local/lib
AA@ubuntu14:/etc/ld.so.conf.d$
sudo ldconfig
这样x265就可以执行了。
6. libopencv
ubuntu17 默认安装的libopencv版本是3.4（https://github.com/opencv/opencv/pull/6586 有workaround），此版本不支持C语言，ffmpeg-3.3.2在configure的时候报下面的错误：
undefined reference to `cvRound’
只能用2.4.13.5（23 Dec 2017）版本的，自己编译，在opencv-2.4.13.5目录下：
mkdir build; cd build/; cmake ..; make -j 2; sudo make install7. openjpeg
ubuntu 17上默认安装的openjpeg版本是2.2的，ffmpeg-3.3.2只支持openjpeg-2.1，在configure的时候会在检测openjpeg的时候失败。解决的办法是直接将/usr/include 下面的openjpeg-2.2改成openjpeg-2.1。
若是修改configure里面的openjpeg检测规则，将openjpeg-2.1改成openjpeg-2.2，这样会有问题，configure后的config.h里面HAVE_OPENJPEG_2_1_OPENJPEG_H定义成0了，最终编译的时候会报错。
8. 编译ffmpeg
从官网上下载ffmpeg-3.3.2，configure命令参考ubuntu镜像服务器上的ffmpeg的，configure命令如下：
./configure --prefix=$(pwd)/install_dir --extra-version='1ubuntu1~trusty6' --build-suffix=-ffmpeg --toolchain=hardened --extra-cflags= --extra-cxxflags= --libdir=/usr/lib/x86_64-linux-gnu --shlibdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --enable-gpl --enable-shared --disable-stripping --enable-avresample --enable-avisynth --enable-fontconfig --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libflite --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libmodplug --enable-libmp3lame --enable-libopenjpeg --enable-libopus --enable-libpulse --enable-librtmp --enable-libschroedinger --enable-libshine --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-opengl --enable-libxvid --enable-libx265 --enable-libdc1394 --enable-libiec61883 --enable-libzvbi --enable-libzmq --enable-frei0r --enable-libx264 --enable-libsoxr --enable-openal --enable-libopencv然后编译：
make; sudo make install将ffmpeg可执行文件的路径加入环境变量：
vi .bashrc在最后加上：
export PATH="PATH:(pwd)/study/ffmpeg/install_dir/bin"$(pwd)不能用~代替，路径必须生成绝对路径，否则找不到nasm。
9. 对比测试
由于电脑上用ffmpeg重编码速度不快，所以想用服务器来跑ffmpeg。两个机器配置：
Pc：

转码命令：
ffmpeg -i input.mp4 -c:v libx264 -c:a aac -cutoff 15000 -ab 95k -strict -2 -async 1 output.mp4X264用ffmpeg默认的参数：

服务器编码54帧/秒。
从测试结果来看，两个机器编码速度差异不大，ffmpeg都是用release版本。有可能是ubuntu上的x264多线程没有真正打开，或打开的方法不对。
