参看：ffmpeg 入门
ffmpeg 之前项目有用到过，最近在做使用 ffmpeg 将 jpeg 转成 mp4，正好借此机会将安装过程说明一下。
Windows下安装方法，可以参看上面的文章。
下载：Download FFmpeg for Windows 该页面里也有相关的 External Libraries 链接
解压后即可使用：
ffmpeg -i C:\ffmpeg\test.avi -b:v 640k c:\ffmpeg\output.ts
现在我讲讲在 Ubuntu 下的安装。
首先需要安装几个必要的解码器：
更多可部分：
接下来开始讲ffmpeg的安装
1、首先下载
下载：ffmpeg 官网下载 下载的版本为 ffmpeg-3.3.1.tar
2、解压
将软件拷贝到指定位置，解压。
tar -xvf ffmpeg-3.3.1.tar3、配置

External library support:
Using any of the following switches will allow FFmpeg to link to the
corresponding external library. All the components depending on that library
will become enabled, if all their other dependencies are met and they are not
explicitly disabled. E.g. --enable-libwavpack will enable linking to
libwavpack and allow the libwavpack encoder to be built, unless it is
specifically disabled with --disable-encoder=libwavpack.
Note that only the system libraries are auto-detected. All the other external
libraries must be explicitly enabled.

基本选项介绍
以下为配置 ffmpeg 的基本选项，其含义如下：
--cache-file=FILE
configure 会在你的系统上测试存在的特性(或者 bug!)。 为了加速随后进行的配置，测试的结果会存储在一个 cache file 里。 当 configure 到每个子树里都有 configure 脚本的复杂的源码树时， 一个很好的 cache file 的存在会有很大帮助。
--help
输出帮助信息。 即使是有经验的用户也偶尔需要使用使用--help 选项， 因为一个复杂的项目会包含附加的选项。 例如， GCC 包里的 configure 脚本就包含了允许你控制是否生成和在 GCC 中使用 GNU 汇编器的选项。
--no-create
configure 中的一个主要函数会制作输出文件。 此选项阻止 configure 生成这个文件。你可以认为这是一种演习(dry run)， 尽管缓存(cache)仍然被改写了。
--quiet
--silent
当 configure 进行他的测试时， 会输出简要的信息来告诉用户正在作什么。 这样做是因为 configure 可能会比较慢， 没有这种输出的话用户将会被扔在一旁疑惑正在发生什么。 使用这两个选项中的任何一个都会把你扔到一旁。 (译注： 这两句话比较有意思， 原文是这样的： If there was no such output， the user would be left wondering what is happening. By using this option， you too can be left wondering!)
--version
打印用来产生'configure'脚本的 Autoconf 的版本号。
--prefix=PEWFIX
--prefix 是最常用的选项。 制作出的 Makefile 会查看随此选项传递的参数， 当一个包在安装时可以彻底的重新安置他的结构独立部分。 举一个例子， 当安装一个包， 例如说 Emacs， 下面的命令将会使 Emacs Lisp file 被安装到"/opt/gnu/share"：
$ ./configure --prefix=/opt/gnu
--exec-prefix=EPREFIX
与--prefix 选项类似，但是他是用来设置结构倚赖的文件的安装位置。编译好的 emacs二进制文件就是这样一个问件。 如果没有设置这个选项的话， 默认使用的选项值将被设为和--prefix 选项值一样。
--bindir=DIR
指定二进制文件的安装位置。 这里的二进制文件定义为可以被用户直接执行的程序。
--sbindir=DIR
指定超级二进制文件的安装位置。 这是一些通常只能由超级用户执行的程序。
--libexecdir=DIR
指定可执行支持文件的安装位置。 与二进制文件相反， 这些文件从来不直接由用户执行， 但是可以被上面提到的二进制文件所执行。
--datadir=DIR
指定通用数据文件的安装位置。
--sysconfdir=DIR
指定在单个机器上使用的只读数据的安装位置。
--sharedstatedir=DIR
指定可以在多个机器上共享的可写数据的安装位置。
--localstatedir=DIR
指定只能单机使用的可写数据的安装位置。
--libdir=DIR
指定库文件的安装位置。
--includedir=DIR
指定 C 头文件的安装位置。 其他语言如 C++的头文件也可以使用此选项。
--oldincludedir=DIR
指定为除 GCC 外编译器安装的 C 头文件的安装位置。
--infodir=DIR
指定 Info 格式文档的安装位置。 Info 是被 GNU 工程所使用的文档格式。
--mandir=DIR
指定手册页的安装位置。
--srcdir=DIR
这个选项对安装没有作用。 他会告诉 configure 源码的位置。 一般来说不用指定此选项， 因为 configure 脚本一般和源码文件在同一个目录下。
--program-prefix=PREFIX
指定将被加到所安装程序的名字上的前缀。例如，使用--program-prefix=g 来 configure一个名为 tar 的程序将会使安装的程序被命名为 gtar。 当和其他的安装选项一起使用时，这个选项只有当他被 Makefile.in 文件使用时才会工作。
--program-suffix=SUFFIX
指定将被加到所安装程序的名字上的后缀。
--program-transform-name=PROGRAM
这里的 PROGRAM 是一个 sed 脚本。 当一个程序被安装时， 他的名字将经过 sed -e
PROGRAM 来产生安装的名字。
--build=BUILD
指定软件包安装的系统平台。 如果没有指定， 默认值将是--host 选项的值。
--host=HOST
指定软件运行的系统平台。 如果没有指定， 将会运行 config.guess 来检测。
--target=GARGET'
指定软件面向(target to)的系统平台。 这主要在程序语言工具如编译器和汇编器上下文中起作用。 如果没有指定， 默认将使用--host 选项的值。
--disable-FEATURE
一些软件包可以选择这个选项来提供为大型选项的编译时配置， 例如使用 Kerberos认证系统或者一个实验性的编译器最优配置。 如果默认是提供这些特性， 可以使用
--disable-FEATURE 来禁用它， 这里 FEATURE 是特性的名字。 例如：
$ ./configure --disable-gui
-enable-FEATURE[=ARG]
相反的， 一些软件包可能提供了一些默认被禁止的特性， 可以使用--enable-FEATURE来起用它。 这里 FEATURE 是特性的名字。 一个特性可能会接受一个可选的参数。 例如：
$ ./configure --enable-buffers=128
--enable-FEATURE=no 与上面提到的--disable-FEATURE 是同义的。
--with-PACKAGE[=ARG]
在自由软件社区里， 有使用已有软件包和库的优秀传统。 当用 configure 来配置一个源码树时， 可以提供其他已经安装的软件包的信息。 例如， 倚赖于 Tcl 和 Tk 的 BLT 器件工具包。 要配置 BLT， 可能需要给 configure 提供一些关于我们把 Tcl 和 Tk 装的何处的信息：
$ ./configure --with-tcl=/usr/local --with-tk=/usr/local
--with-PACKAGE=no 与下面将提到的--without-PACKAGE 是同义的。
--without-PACKAGE
有时候你可能不想让你的软件包与系统已有的软件包交互。 例如， 你可能不想让你的新编译器使用 GNU ld。 通过使用这个选项可以做到这一点：
$ ./configure --without-gnu-ld
--x-includes=DIR
这个选项是--with-PACKAGE 选项的一个特例。 在 Autoconf 最初被开发出来时， 流行使用 configure 来作为 Imake 的一个变通方法来制作运行于 X 的软件。 --x-includes 选项提供了向 configure 脚本指明包含 X11 头文件的目录的方法。
--x-libraries=DIR
类似的， --x-libraries 选项提供了向 configure 脚本指明包含 X11 库的目录的方法
以下为配置 ffmpeg 的基本选项，其含义如下：
--cache-file=FILE
configure 会在你的系统上测试存在的特性(或者 bug!)。 为了加速随后进行的配置，测试的结果会存储在一个 cache file 里。 当 configure 到每个子树里都有 configure 脚本的复杂的源码树时， 一个很好的 cache file 的存在会有很大帮助。
--help

指定将被加到所安装程序的名字上的后缀。
--program-transform-name=PROGRAM
这里的 PROGRAM 是一个 sed 脚本。 当一个程序被安装时， 他的名字将经过 sed -e
PROGRAM 来产生安装的名字。
--build=BUILD
指定软件包安装的系统平台。 如果没有指定， 默认值将是--host 选项的值。
--host=HOST
指定软件运行的系统平台。 如果没有指定， 将会运行 config.guess 来检测。
--target=GARGET'
指定软件面向(target to)的系统平台。 这主要在程序语言工具如编译器和汇编器上下文中起作用。 如果没有指定， 默认将使用--host 选项的值。
--disable-FEATURE
一些软件包可以选择这个选项来提供为大型选项的编译时配置， 例如使用 Kerberos认证系统或者一个实验性的编译器最优配置。 如果默认是提供这些特性， 可以使用
--disable-FEATURE 来禁用它， 这里 FEATURE 是特性的名字。 例如：
$ ./configure --disable-gui
-enable-FEATURE[=ARG]
相反的， 一些软件包可能提供了一些默认被禁止的特性， 可以使用--enable-FEATURE来起用它。 这里 FEATURE 是特性的名字。 一个特性可能会接受一个可选的参数。 例如：
$ ./configure --enable-buffers=128
--enable-FEATURE=no 与上面提到的--disable-FEATURE 是同义的。
--with-PACKAGE[=ARG]
在自由软件社区里， 有使用已有软件包和库的优秀传统。 当用 configure 来配置一个源码树时， 可以提供其他已经安装的软件包的信息。 例如， 倚赖于 Tcl 和 Tk 的 BLT 器件工具包。 要配置 BLT， 可能需要给 configure 提供一些关于我们把 Tcl 和 Tk 装的何处的信息：
$ ./configure --with-tcl=/usr/local --with-tk=/usr/local
--with-PACKAGE=no 与下面将提到的--without-PACKAGE 是同义的。
--without-PACKAGE
有时候你可能不想让你的软件包与系统已有的软件包交互。 例如， 你可能不想让你的新编译器使用 GNU ld。 通过使用这个选项可以做到这一点：
$ ./configure --without-gnu-ld
--x-includes=DIR
这个选项是--with-PACKAGE 选项的一个特例。 在 Autoconf 最初被开发出来时， 流行使用 configure 来作为 Imake 的一个变通方法来制作运行于 X 的软件。 --x-includes 选项提供了向 configure 脚本指明包含 X11 头文件的目录的方法。
--x-libraries=DIR
类似的， --x-libraries 选项提供了向 configure 脚本指明包含 X11 库的目录的方法
进入 ffmpeg-3.3.1 并配置
# cd ffmpeg-3.3.1
# ./configure --enable-shared --prefix=/usr/local/ffmpeg --enable-gpl --enable-libx264 --extra-cflags=-I/usr/local/include --extra-ldflags=-L/usr/local/lib
yasm/nasm not found or too old. Use --disable-yasm for a crippled build.
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.安装 yasm：
# apt-get install yasm
或者按照提示直接在配置上添加 --disable-yasm
重新执行：
./configure --enable-shared --prefix=/usr/local/ffmpeg --enable-gpl --enable-libx264 --extra-cflags=-I/usr/local/include --extra-ldflags=-L/usr/local/lib --enable-libmp3lame --disable-yasm 4、编译
先执行，时间有点长，需要等几分钟：
# make# make install5、检查是否安装成功
查看 ffmpeg 版本：
# /usr/local/ffmpeg/bin/ffmpeg --version
/usr/local/ffmpeg/bin/ffmpeg: error while loading shared libraries: libavdevice.so.57: cannot open shared object file:
No such file or directory
修改文件 /etc/ld.so.conf 内容增加 /usr/local/ffmpeg/lib/
vi /etc/ld.so.conf
在最后添加：
/usr/local/ffmpeg/lib/# ldconfig
重新查看 ffmpeg 版本：
# /usr/local/ffmpeg/bin/ffmpeg -version
