资料准备

名称 描述
gcc gcc (Ubuntu 5.4.0-6ubuntu1~16.04.11) 5.4.0 c编译器
linux Ubuntu 6.04 操作系统
yasm yasm 1.3.0 汇编编译器
源码 git clone https://github.com/FFmpeg/FFmpeg.git (Github)源码
源码 http://ffmpeg.org/download.html#build-linux (官网)源码
二进制文件(win) http://ffmpeg.zeranoe.com/builds/ 二进制程序

注: 18.04 直接执行命令: sudo apt install ffmpeg 就可以了

0. 检查依赖yasm与gcc,以及pkg-config

linux默认安装了gcc,如果你确实没有安装gcc,那么你需要安装一下gcc;
FFmpeg中有部分汇编代码,因此需要编译该部分代码,安装yasm即可,你可以认为yasm就是一个汇编编译器,安装 yasm 的目的在于提高 ffmpeg 的编译速度。

如果没有就安装


# apt-get install yasm
# apt-get install gcc


检查pkg-config
如果显示以下信息,请参考我另一篇博文《Ubuntu 16.04 下pkg-config的安装与简介
注: 18.04 直接执行命令: sudo apt-get install pkg-config 就可以了,但是!默认安装的ffmpeg是3.7版本,对ffmpeg版本有要求的不建议使用此方法。

这里有warning,查了一些资料emmm不好不好,有大佬知道如何解决,可以附在评论,我学习一下,完善资料。

5. 检查安装情况

5.1 这里有两个问题:

资料说必须到安装所在的文件夹查看版本信息,当我执行 :ffmpeg --version
报错:


Unrecognized option '-version'.
Error splitting the argument list: Option not found

当我执行 :ffmpeg -version
不会报错。。。

6. ffmpeg -version出现 ffmpeg command not found解决办法

如果显示以下信息,请参考我另一篇博文《ffmpeg 检查版本:ffmpeg -version出现 ffmpeg command not found解决办法

7. 安装opencv

这里就简单了

依赖:opencv2.4版本以上
为达到减少验证工作量的目的,这里样例在ubuntu16.04上验证基本功能,安装opencv使用apt工具,安装步骤如下:

$ sudo apt update 
$ sudo apt install libopencv-dev python-opencv

安装结束。检查一下是否安装成功:

$ pkg-config --modversion opencv

结果输出:

2.4.9.1

最后检测版本如果报错,记得在~/.bashrc 添加环境变量。
或者直接export PKG_CONFIG_PATH=/path/of/opencv.pc
