Ubuntu 16.04安装编译FFmpeg

在Ubuntu 16.04环境下安装编译FFmpeg过程步骤，本文主要基于此官方指导编译。

1. 安装依赖
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
mkdir ~/ffmpeg_sources  //根目录下创建文件夹

2. Compilation & Installation

Yasm
sudo apt-get install yasm

libx264
sudo apt-get install libx264-dev

libx265
sudo apt-get install cmake mercurial
cd ~/ffmpeg_sources
hg clone https://bitbucket.org/multicoreware/x265
cd ~/ffmpeg_sources/x265/build/linux
PATH=”$HOME/bin:$PATH” cmake -G “Unix Makefiles” -DCMAKE_INSTALL_PREFIX=”$HOME/ffmpeg_build” -DENABLE_SHARED:bool=off ../../source
make
make install
make distclean

libfdk-aac
cd ~/ffmpeg_sources
wget -O fdk-aac.tar.gz https://github.com/mstorsjo/fdk-aac/tarball/master
tar xzvf fdk-aac.tar.gz
cd mstorsjo-fdk-aac*
autoreconf -fiv
./configure –prefix=”$HOME/ffmpeg_build” –disable-shared
make
make install
make distclean

libmp3lame
sudo apt-get install libmp3lame-dev

libopus
sudo apt-get install libopus-dev

libvpx
cd ~/ffmpeg_sources
wget http://storage.googleapis.com/downloads.webmproject.org/releases/webm/libvpx-1.5.0.tar.bz2
tar xjvf libvpx-1.5.0.tar.bz2
cd libvpx-1.5.0
PATH=”$HOME/bin:$PATH” ./configure –prefix=”$HOME/ffmpeg_build” –disable-examples –disable-unit-tests
PATH=”$HOME/bin:$PATH” make
make install
make clean

avdevice
sudo apt-get install libavdevice-dev

ffmpeg

cd ~/ffmpeg_sources
wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
tar xjvf ffmpeg-snapshot.tar.bz2
cd ffmpeg
PATH=”$HOME/bin:$PATH” PKG_CONFIG_PATH=”$HOME/ffmpeg_build/lib/pkgconfig”
./configure –prefix=”$HOME/ffmpeg_build” –pkg-config-flags=”–static”  –extra-cflags=”-I$HOME/ffmpeg_build/include”  –extra-ldflags=”-L$HOME/ffmpeg_build/lib”  –bindir=”$HOME/bin”  –enable-gpl  –enable-libass  –enable-libfdk-aac  –enable-libfreetype  –enable-libmp3lame  –enable-libopus  –enable-libtheora  –enable-libvorbis  –enable-libvpx  –enable-libx264  –enable-libx265  –enable-nonfreePATH=”$HOME/bin:$PATH” makemake installmake distcleanhash -r

到这里ffmpeg就编译安装结束了，编译过的ffmpeg在~/bin 目录下

Usage
两种方法使用ffmpeg

进入~/bin文件夹，然后调用binary文件: cd ~/bin && ./ffmpeg -i ~/input.mp4 ~/videos/output.mkv
使用绝对路径：/home/yourusername/bin/ffmpeg -i ../input.mp4 ../videos/output.mkv
如果想要ffmpeg在所有地方都能直接调用，需要先注销，然后登陆。
或者执行source ~/.profile

Documentation
如果想要用man ffmpeg命令看文档，执行下面命令

echo “MANPATH_MAP $HOME/bin $HOME/ffmpeg_build/share/man” >> ~/.manpath

注销，然后登陆即可。

更新FFmpeg
rm -rf ~/ffmpeg_build ~/ffmpeg_sources ~/bin/{ffmpeg,ffprobe,ffplay,ffserver,vsyasm,x264,x265,yasm,ytasm}

然后从头开始再来一次
