The source archive is a separate download beside the mod installation ZIP.
It supplies source for the whole tools, including their command-line code
and FFmpeg libraries, under GPL 3.0 sections 4-6 incorporated by LGPL 3.0.
It does not need to be installed. You may rebuild or replace these tools.
The mod starts them as separate processes. Close Valheim before replacing
Tools/FFmpeg/ffmpeg.exe and ffprobe.exe, or configure FFmpegPath and
FFprobePath in the shared Mods settings menu.

COPYING.GPLv3 and COPYING.GCC-RUNTIME.txt. Project build scripts and the
response-file patch use MIT; see BUILD-SCRIPTS-LICENSE.txt in the source
archive. Original build manifests retain the upstream license identifier.
