Missing ffmpeg

For Windows systems, the pre-packaged version already includes ffmpeg, so no action is required. The source code contains an ffmpeg.7z file; extract it and place it in the software's root directory.

For Linux systems, on Debian-based distributions, you can install it using apt-get install ffmpeg, or on Fedora-based distributions, use yum install ffmpeg.

For macOS, install it using brew install ffmpeg.

Installing ffmpeg

Why install it? If an AI project involves audio or video, it almost certainly requires ffmpeg, so installation is recommended.

Download ffmpeg and Set Environment Variables

Download link for the Windows version of ffmpeg:

https://www.gyan.dev/ffmpeg/builds/packages/ffmpeg-6.1.1-full_build.7z

Download other versions here: https://www.gyan.dev/ffmpeg/builds/

After downloading, extract the archive and navigate to the bin directory. You will see three .exe files. Copy them to a directory with an English path, for example, I copied them to the folder E:\sdk\ffmpeg. Then, add this path to the Path environment variable.

How to Add to the Path Environment Variable: Press the Win key + Pause key (top right). In the window that opens, click sequentially: Advanced system settings -> Environment Variables -> System variables -> find the Path line and double-click it.

Then, click New -> Browse, and navigate to the directory containing those three .exe files.

In the browse dialog, find the directory containing the previously mentioned ffmpeg.exe file, then click OK.

You will now see the newly added path on the left. Click OK to close, then click OK on all subsequent dialogs to close them.

Verify the Installation

Open any Command Prompt (cmd) window and type ffmpeg then press Enter. If it displays information similar to the following, the installation is correct. If you see a message like "'ffmpeg' is not recognized as an internal or external command...", it means there was an error configuring the environment variables. Please reconfigure them.
