# Cross-compiles the LGPL ffmpeg.exe + ffprobe.exe for Windows x64 (MinGW-w64).
# The arm64 MSIX ships the same x64 binaries: Windows on Arm runs them under
# emulation, and the encoding is done by the GPU/Media Foundation anyway.
# Built by build-windows.sh; the tarball is passed in (already checksummed).
