ubuntu 安装ffmpeg

第一种方法：

sudo add-apt-repository ppa:kirillshkrogalev/ffmpeg-next

sudo apt-get update

sudo apt-get install ffmpeg

第二种方法：（已经有源码包，可以在http://ffmpeg.org/releases/ 下载） 参考官网介绍：https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

1.安装附加依赖项

sudo apt-get update

sudo apt-get -y install autoconf automake build-essential libass-dev libfreetype6-dev \
  libsdl1.2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev \
  libxcb-xfixes0-dev pkg-config texinfo zlib1g-dev

官网说Note:  Server users can omit the  ffplay  and x11grab dependencies:  libsdl1.2-dev libva-dev libvdpau-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev .也就是我们可以不安装这些依赖包，前提我们是server users

sudo aptitude install libfaac-dev

sudo aptitude install libmp3lame-dev

sudo aptitude install libtheora-dev 

<span style="font-family: Arial, Helvetica, sans-serif;">sudo aptitude install libvorbis-dev</span>

<span style="font-family: Arial, Helvetica, sans-serif;">sudo aptitude install libxvidcore-dev</span>

sudo aptitude install libxext-dev

<span style="font-family: Arial, Helvetica, sans-serif;">sudo aptitude install libxfixes-dev</span>

<span style="font-family: Arial, Helvetica, sans-serif;">
</span>

2.接下来 安装 Yasm

An assembler for x86 optimizations used by x264 and FFmpeg. Highly recommended or your resulting build may be very slow.

If your repository offers a yasm package ≥ 1.2.0 then you can install that instead of compiling:

方法一：sudo apt-get install yasm

Otherwise you can compile:

方法二：

cd ~/ffmpeg_sources
wget 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
make distclean

3.接下来安装 libx264 ， 同样有两种方法

H.264 video encoder. See the H.264 Encoding Guide for more information and usage examples.

Requires ffmpeg to be configured with --enable-gpl --enable-libx264.

If your repository offers a libx264-dev package ≥ 0.118 then you can install that instead of compiling:

sudo apt-get install libx264-dev

Otherwise you can compile:

cd ~/ffmpeg_sources
wget http://download.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
tar xjvf last_x264.tar.bz2
cd x264-snapshot*
PATH="$HOME/bin:$PATH" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static
PATH="$HOME/bin:$PATH" make
make install
make distclean

4.最后安装ffmpeg ，切换到你下载的ffmpeg安装包目录 比如cd  ～/Dowload/

tar -jxvf  你的安装包（ffmpeg-2.4.1.tar.bz2） 

cd ffmpeg-2.4.1 （这里为你的解压目录）

<span style="font-family: Monaco, 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', Consolas, 'Courier New', monospace; line-height: 18px; background-color: rgb(250, 250, 250);">编译 ./configure --prefix=/usr/local/ffmpeg --enable-gpl --enable-version3 --enable-nonfree --enable-postproc --enable-pthreads --enable-libfaac --enable-libmp3lame --enable-libtheora --enable-libx264 --enable-libxvid --enable-x11grab --enable-libvorbis </span>

5.安装

make

sudo make install

最后你可以用 whereis ffmpeg 查看你安装的目录
