Missing FFmpeg?

If you get the error:

Manually download both and place them in:

  • Windows: %APPDATA%\Nix\Resources\ffmpeg\ and \zstd\

  • Linux: ~/.config/Nix/Resources/

  • macOS: ~/Library/Application Support/Nix/Resources/

You can download the exact executable files you need using the links below. If you prefer, you may also visit the official websites, but note that you'll need to locate the correct versions on your own:

Manual FFmpeg Decompression Using ZSTD

If after placing these files you still see the error:

You will need to manually decompress the FFmpeg file using the ZSTD executable.

Step-by-step instructions:

  1. Make sure the ZSTD file is in the same folder as your ffmpeg_uncompressed.

  2. Open your terminal or command prompt.

  3. Navigate to the folder where both files are located, for example:

    cd Nix\Resources\ffmpeg\
  4. Run this command to decompress the ffmpeg file:

    zstd -d ffmpeg_compressed_<version> -o ffmpeg.exe
  • Replace <version> to correctly reflect the file name and extension if on windows.

  • Use ffmpeg instead of ffmpeg.exe on Linux/macOS.

  • This command decompresses the archive and outputs the usable FFmpeg executable in the same folder.

  1. (Linux/macOS only) Make the FFmpeg file executable:

    chmod +x ffmpeg
  2. Restart the app — it should now detect FFmpeg properly.
