Installing FFmpeg on Windows

Why install it? If your AI project involves audio or video, you'll almost certainly need it. Therefore, it's recommended to install it.

Download FFmpeg and Set Environment Variables

FFmpeg Windows version download address:

https://www.gyan.dev/ffmpeg/builds/#release-builds

Choose to download the ffmpeg-release-full.7z archive. This includes support for all common libraries. After downloading, extract it and go to the bin directory. You'll see three .exe files. Copy them to an English directory, for example, E:\sdk\ffmpeg. Then, add this path to the Path environment variable.

How to add the Path environment variable: Press the Win key + Pause key (top right corner). In the opened window, click on: Advanced system settings -> Environment Variables -> System variables -> Find the Path row and double-click it.

Then, click New -> Browse, find the directory where the three .exe files are located.

In the browse dialog, find the directory where ffmpeg.exe is located and click OK.

Then, you'll see the newly added path on the left. Click OK to close, and click OK all the way to close all opened dialog boxes.

Verify successful installation

Open any cmd window and enter ffmpeg, press Enter. If the following is displayed, it means the installation is correct. If it says "ffmpeg is not a recognized command or...", it means you made a mistake when configuring the environment variables. Please reconfigure.
