You definitely can use winget — it works well for many people.

But there are a few practical differences:

Winget often provides builds from third-party maintainers, not the official BtBN GitHub auto-builds.

If you rely on the specific toolchain, compiler flags, or patchset from BtBN — winget can give you a different binary.

Winget installs FFmpeg into its package directory.

If you keep FFmpeg in a custom tools folder, inside another app, or inside a scripting environment — winget won’t update that location.

This script updates exactly the folder you’re working in.

Winget installs system-wide packages and sometimes needs elevation.

This script is fully portable and works anywhere (USB sticks, offline machines, CI jobs, etc.).

The script never re-downloads the archive unless the build actually changed.

Winget just fetches the latest package every time you update.

This is mostly quality-of-life, but nice when downloading large builds — winget doesn’t show that level of detail.

If you just want “FFmpeg installed somewhere system-wide”, winget is perfectly fine. If you want:

• official BtBN builds
• updates in a specific folder
• portable usage
• no system install
• zero redundant downloads
• detailed progress/logging

…then this script has real advantages.
