This script is a fork of Roger Pack's ffmpeg-windows-build-helpers. It helps me to compile (FFmpeg) binaries that are Windows XP compatible and will work on old CPUs without SSE2 instruction sets (like my own AMD Athlon XP 3200+).
FFmpeg has officially dropped support for Windows XP, but I'll try to create fresh binaries and update the script nonetheless.
