ubuntu16.04上怎么编译安装ffmpeg(ffmpeg,ubuntu,开发技术)

ffmpeg是在 Linux 下开发出来的一套可以用来记录、转换数字音频、视频，并能将其转化为流的开源计算机程序。它包括了目前领先的音视频编码库libavcodec。

\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

sudoapt-getinstallyasm

libx264

sudoapt-getinstalllibx264-dev

libx265

sudoapt-getinstallcmakemercurialcd~/ffmpeg_sourceshgclonehttps://bitbucket.org/multicoreware/x265cd~/ffmpeg_sources/x265/build/linuxPATH="$HOME/bin:$PATH"cmake-G"UnixMakefiles"-DCMAKE_INSTALL_PREFIX="$HOME/ffmpeg_build"-DENABLE_SHARED:bool=off../../sourcemakemakeinstallmakedistclean

libfdk-aac

libmp3lame

libopus

sudoapt-getinstalllibopus-dev

libvpx

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
