FFmpeg installation and download (linux and windows)

1、Windows

Log in to the official website of FFmepg: http://ffmpeg.org/download.html

wget https://github.com/BtbN/FFmpeg-Builds/releases/download/autobuild-2020-11-05-12-30/ffmpeg-N-99863-g70d8077b79-win64-gpl-shared-vulkan.zip

Download and unzip it to a local file, and then add it to the environment variable
C:\FFmpeg\ffmpeg-N-99863-g70d8077b79-win64-gpl-shared-vulkan\bin to
open the cmd window and enter ffmepg to open it.

2、Linux

(1) Download the installation package

Log in to the official website of FFmepg: http://ffmpeg.org/download.html to

view the linux kernel:

cat /proc/version

3.10.0 meets the version requirements and can be installed.

Enter the installation instructions document: https://www.johnvansickle.com/ffmpeg/faq/
which can be downloaded by the following command

wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-amd64-static.tar.xz
wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-amd64-static.tar.xz.md5

(2) Installation

Unzip the file

tar xvf ffmpeg-git-amd64-static.tar.xz

You will get the folder ffmpeg-git-20201104-amd64-static

cd ffmpeg-git-20201104-amd64-static

View the contents of the folder

ls

Currently you can already run in the current directory, and you can also run through the absolute path

./ffmpeg

(3) Environmental configuration

View your environment variables

echo $PATH

Check if there is an old version of ffmpeg

whereis ffmpeg 

If it exists, you need to delete it first. If it does not exist, you need to do the following directly

sudo cp ffmpeg-git-20201104-amd64-static/ffmpeg ffmpeg-git-20201104-amd64-static/ffprobe /usr/local/bin/

Check the location of ffmpeg and ffprobe

whereis ffmpeg
whereis ffprobe

Enter ffmpeg directly on the command line to run

3. Mirror production

You can refer to my other article docker image creation, import and export to build ffmepg docker image, here is my docker image tar package, after decompression, you can use it directly.
