FFMpeg Objects - C++ & JMF bindings / Discussion / user: Compiling on Windows using MINGW

Hi,
I downloaded the latest 0.4.2 source and have been working on compiling the latest source on Windows XP Professional. Following the instruction in the INSTALL file, I managed to compile ffmpeg, however when I try to compile using the following command line:

./buildFobs.sh FFMPEG_HOME=/c/java/fobs-0.4.2/ffmpeg FOBS4JMF=yes OPTIMIZATIONS=yes

I get the following error:

KeyError: 'Libs':
File "C:\java\fobs-0.4.2\SConstruct", line 30:
env_ffmpeg.MergeFlags(res.get_output())
File "C:\java\fobs-0.4.2/scripts\fobscons.py", line 61:
return self['Libs']+" "+self['Cflags']

The reason I want to build and compile 0.4.2 is because I am getting JVM crash when I try to play a .FLV file.
Appreciate any help and pointers.
