# Third-party software

BrowserCast does not bundle FFmpeg in the Chrome extension package.

On Windows, the BrowserCast installer first checks whether `ffmpeg.exe` is
available through the process `PATH`. If it is not, the installer downloads the
FFmpeg Essentials archive published by Gyan Doshi, verifies it against the
publisher's SHA-256 checksum, and installs only `ffmpeg.exe` beside the
BrowserCast native host.

- Windows builds used by the installer: <https://www.gyan.dev/ffmpeg/builds/>
- FFmpeg license information: <https://ffmpeg.org/legal.html>
- Corresponding source links: <https://www.gyan.dev/ffmpeg/builds/#source>

FFmpeg is a separate program and remains subject to its own license. The
Essentials build currently selected by the installer is distributed under
GPLv3 by its publisher.
