Windows-only NeoForge companion mod for the workspace's ReplayMod distribution. It carries a pinned Gyan FFmpeg essentials executable and installs it into the game directory before ReplayMod can render.
The build downloads the fixed FFmpeg archive through Gradle, verifies its SHA-256, and packages only
ffmpeg.exe, LICENSE, and README.txt. The archive and extracted build files are not committed.
At runtime the mod installs to ffmpeg/bin/ffmpeg.exe using a temporary file, SHA-256 verification,
an inter-process lock, and an atomic move. Existing player-managed files without the runtime marker are
never overwritten. On non-Windows systems the mod is inert.
