# Bundled binaries

AeroFetch spawns these from the **main process** and bundles them via
electron-builder `extraResources` (they ship outside the asar archive). They are
**not** committed to git (see `.gitignore`).

Drop the two required Windows executables here before running `npm run dev` or
building; `aria2c.exe` is optional:

```
resources/bin/
├── yt-dlp.exe
├── ffmpeg.exe
└── aria2c.exe   (optional)
```

## yt-dlp.exe

- Download: https://github.com/yt-dlp/yt-dlp/releases/latest
- Grab `yt-dlp.exe`.
- Unlicense / public domain.

## ffmpeg.exe

- Use an **LGPL** build to keep licensing simple, e.g.
  https://github.com/BtbN/FFmpeg-Builds/releases (pick a `*-lgpl-shared` or
  `*-lgpl` win64 build) or https://www.gyan.dev/ffmpeg/builds/.
- Copy `ffmpeg.exe` here. Ship the LGPL license text alongside the installer
  before release.

## aria2c.exe (optional)

- Powers the "Use aria2c downloader" toggle in Settings → Network for faster
  multi-connection downloads. If it's missing, that toggle silently falls back
  to yt-dlp's built-in downloader — nothing breaks.
- Download: https://github.com/aria2/aria2/releases (grab the `aria2-*-win-64bit-build1.zip`,
  copy `aria2c.exe` from it here).
- GPL-2.0 — ship its license text alongside the installer before release if bundled.

> Branding stays generic: AeroFetch is a "yt-dlp frontend." Keep upstream
> license texts with any distributed build.
