Ubuntu 16.04/18.04/20.04 安装 ffmpeg4.4

​ 最近在玩以太网推视频流。由于自身不是做上层应用层软件出生,只能现有工具的手段完成。通过Google和度娘搜索有两种方案:FFmpeg和GStreamer的方案。最终我选择使用FFmpeg工具。

FFmpeg_百度百科 (baidu.com) 是一套可以用来记录、转换数字音频、视频,并能将其转化为流的开源计算机程序。采用LGPL或GPL许可证。它提供了录制、转换以及流化音视频的完整解决方案。它包含了非常先进的音频/视频编解码库libavcodec,为了保证高可移植性和编解码质量,libavcodec里很多code都是从头开发的。

FFmpeg在Linux平台下开发,但它同样也可以在其它操作系统环境中编译运行,包括Windows、[Mac OS X](https://baike.baidu.com/item/Mac OS X/470629)等。这个项目最早由Fabrice Bellard发起,2004年至2015年间由Michael Niedermayer主要负责维护。许多FFmpeg的开发人员都来自MPlayer项目,而且当前FFmpeg也是放在MPlayer项目组的服务器上。项目的名称来自MPEG视频编码标准,前面的”FF”代表”Fast Forward”。 [1] FFmpeg编码库可以使用GPU加速。

​ 我的Linux服务器是Ubuntu16.04。下面方法适用于Ubuntu16.04以上任何版本的Ubuntu。

给当前Ubuntu添加PPA源

​ PPA是Personal Package Archives首字母简写。翻译为中文意思是:个人软件包文档。只有Ubuntu用户可以用,而所有的PPA都是寄存在launchpad.net网站上。使用PPA的好处是Ubuntu系统中使用PPA源的软件可以让你在第一时间体验到最新版本的软件。

​ 所以我们需要在launchpad.net网站上搜索我们对应Ubuntu16.04的ffmpeg4 ppa软件包。

Ubuntu 16.04/18.04/20.04 安装 ffmpeg4.4

点开FFmpeg 4 – media tool (Xenial & newer) : Rob Savoury

Ubuntu 16.04/18.04/20.04 安装 ffmpeg4.4

非常感谢Rob Savoury,他的ppa:savoury1包含了Ubuntu版本比较多从Ubuntu 16.04(Xenial)到Ubuntu20.04(Focal)。

增加PPA并升级相应的软件包:

$ sudo add-apt-repository ppa:savoury1/graphics
$ sudo add-apt-repository ppa:savoury1/multimedia
$ sudo add-apt-repository ppa:savoury1/ffmpeg4
$ sudo apt-get update
$ sudo apt-get upgrade && sudo apt-get dist-upgrade
$ sudo apt-get install ffmpeg

命令log如下:

$ sudo add-apt-repository ppa:savoury1/graphics
$ sudo add-apt-repository ppa:savoury1/multimedia
$ sudo add-apt-repository ppa:savoury1/ffmpeg4
 FFmpeg 4.4 builds (and associated multimedia packages) for Xenial & newer.

Update (8 May 2021): FFmpeg 4.4 uploads from today onwards are built with these additional optional libraries: glslang (shader support), SVT-AV1 (scalable AV1 encoder), zimg (scaling, colorspace conversion, dithering), Vulkan (GPU acceleration on supported hardware), and SMB (Samba sharing).

*** Install ***

FFmpeg can be installed from this PPA alone, as the required packages to satisfy minimum versions have been copied here (notify me if any missing). However, if _all_ newest versions of graphics and multimedia packages are desired then two additional PPAs can be added before installing FFmpeg:

  sudo add-apt-repository ppa:savoury1/graphics
  sudo add-apt-repository ppa:savoury1/multimedia
  sudo add-apt-repository ppa:savoury1/ffmpeg4
  sudo apt-get update
  sudo apt-get upgrade && sudo apt-get dist-upgrade
  sudo apt-get install ffmpeg

......
......

*** Build ***

This PPA has build dependencies on:

  ppa:savoury1/build-tools
  ppa:savoury1/backports
  ppa:savoury1/graphics
  ppa:savoury1/multimedia

*** Credits ***

给开发板安装FFmpeg-static

由于开发板跑Linux不具备和PC Ubuntu一样的能力。所以最快捷的方式是使用FFmpeg-static静态编译,生成可执行文件直接在板子上跑。

这个得感谢github的Jonas ChevalierJohn Van Sickle。两个人分别提供了现成的编译脚本或者编译文件。

1. 首先我说一下Jonas Chevalier如何编译。

Ubuntu用户直接用下面一条命令即可:

sudo ./build-ubuntu.sh   #似乎这个5年没有人更新了编译有问题。这个必须是基于Ubuntu18.04的版本。

最近更新的是Dockerfilebuild.sh。浏览了Dockerfile

FROM ubuntu:bionic
# bionic is Ubuntu18.04
# Basic packages needed to download dependencies and unpack them.
RUN apt-get update && apt-get install -y /
  bzip2 /
  perl /
  tar /
  wget /
  xz-utils /
  && rm -rf /var/lib/apt/lists/*

# Install packages necessary for compilation.
RUN apt-get update && apt-get install -y /
  autoconf /
  automake /
  bash /
  build-essential /
  cmake /
  curl /
  frei0r-plugins-dev /
  gawk /
  libfontconfig-dev /
  libfreetype6-dev /
  libopencore-amrnb-dev /
  libopencore-amrwb-dev /
  libsdl2-dev /
  libspeex-dev /
  libtheora-dev /
  libtool /
  libva-dev /
  libvdpau-dev /
  libvo-amrwbenc-dev /
  libvorbis-dev /
  libwebp-dev /
  libxcb1-dev /
  libxcb-shm0-dev /
  libxcb-xfixes0-dev /
  libxvidcore-dev /
  lsb-release /
  pkg-config /
  sudo /
  tar /
  texi2html /
  yasm /
  && rm -rf /var/lib/apt/lists/*

# Copy the build scripts.
COPY dl.tar.gz build.sh download.pl env.source fetchurl /ffmpeg-static/

VOLUME /ffmpeg-static
WORKDIR /ffmpeg-static
CMD /bin/bash

所以我基于Docker编译,如何搭建Docker环境,大家可以参考**Ubuntu16.04/18.04/20.04下安装Docker**。

由于国内强的问题,build.sh里去下载文件的时候会失败。大家可以wget https://gitee.com/msntec/open-source-tool/blob/master/ffmpeg/static/dl.tar.gz到ffmpeg-static目录里。

# 根据当前目录的Dockerfile创建ffmpeg-static镜像
$ docker build -t ffmpeg-static .
# 运行ffmpeg-static镜像
$ docker run -it ffmpeg-static
# 编译生成静态文件
$ ./build.sh 

静态的ffmpeg等文件即将被创建再/ffmpeg-static/bin目录下:

root@54ad0ea1b861:/ffmpeg-static/bin# ls -al
total 85340
drwxr-xr-x 2 root root     4096 Oct 15 09:23 .

2. 我们在说一下John Van Sickle的方法。

John Van Sickle比较直接,他已经提供好了直接的静态镜像给大家。

Ubuntu 16.04/18.04/20.04 安装 ffmpeg4.4

x86_64,x86_32,Arm64,Arm32静态镜像都有。也提供相应的静态编译源码给大家自行编译。

下面我直接拿x86_64解压作为运行实例
