The 32b : Opal error has not struck me (yet?), but the 64b: ffmpeg one.
Have you applied any patch to ffmpeg? The ffmpeg revision 14200 you are
using is quite old and only works with old Win32 headers. I currently
use 17504 - it helped me porting from Debian Multimedia to Ubuntu. With
that version you need recent Win32 headers. You can copy them where the
old ones are or use my Mingw runtime package.
http://wwwuser.gwdg.de/~mrickma/ekiga/mingwrt/mingw32-runtime_3.15-1_all.deb
And add --disable-ffmpeg --disable-ffplay to confffmpeg: in your
Makefile.
