MinGW/MSYS

MinGW and msys are required to build ffmpeg under windows (actually, you can use cygwin also however this is a less well documented option). The installation of MinGW and msys is somewhat confusing, however the internet comes to the rescue.

  • a very good guide
• http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2006-April/010355.html
  • the instructions here are largely correct, and work fine up until the point at which ffmpeg should be build.
  • don't forget to perform this step also:

• if you have an older installation of MinGW and msys, then some things may be wrong:
  • missing pr.exe
  • bash is broken
  • to fix, install newer coreutils (for pr.exe) and bash packages.
