I use the same one, but usually not in command-line. Note that the free 
command-line version of MS compiler cannot create DLLs and use the DLL 
runtime. So it cannot build the GStreamer parts... So makefiles for 
nmake should be generated instead of the GNU Make ones, as nmake ships 
with MSVC.

Since a number of the makefiles present all had logic to insure that PREFIX and IIPREFIX were present and to default to the c:\usr hierarchy you have set up, I found it necessary to issue a SET PREFIX=C:\gstreamer\usr and SET IIPREFIX=C:\\gstreamer\\usr before I issued the NMAKE -f makefile.msvc DEBUG=1 command. This kept these environment variables around for each makefile process.

Yes, the main makefile includes this :
!if !defined(PREFIX)
PREFIX = c:\usr
!endif
!if !defined(IIPREFIX)
IIPREFIX = c:\\usr
!endif

It's even documented on the top of the main makefile of the dependencies.

Yes. the "bin" directory of GStreamer has to be added to the PATH. The 
same goes for the "plugins" directory in the GStreamer directory 
hierarchy (when installed).

> Did you compile gstreamer under MSVC or under cygwin or msys? I attempted to compile under msys, but configure said I was missing a suitable version of python and bison was missing altogether.

Only MSVC with NMAKE (dependencies) and GNU Make on command-line (maybe 
the makefiles are not kept up to date).

See http://mukoli.free.fr/gstreamer/ :

" NOTE : GNU tools needed that you can find on 
http://gnuwin32.sourceforge.net/
- GNU flex
- GNU bison
and http://www.mingw.org/
- GNU make "

I didn't use python at all, nor Perl.
