I don't use MSVC to build ffmpeg. All the external libraries are built using
mingw/msys and then I add to the OAbuild "builddeps" dir the includes, dll's
and impot libraries used by OABuild.
The problem with the original OABuild method is that all the external
libraries are built using MSVC, and that's why it doesn't provide support
for many external plugins, because not all the external dependencies can be
compiled using MSVC.

The changes in the GStreamer code are just a few lines. Take a look at
http://codeanticode.wordpress.com/2008/09/12/the-gstreamer-adventure-part-i-creating-a-windows-installer/.
For the ffmpeg plugin the lines to changes are 4:


   - In gstffmpegenc.c do: replace in_plugin = first_avcodec; by in_plugin =
   av_codec_next(NULL); and in_plugin = in_plugin->next; by in_plugin =
   av_codec_next(in_plugin);
   - In gstffmpegdec.c, do: replace in_plugin = first_avcodec; by in_plugin
   = av_codec_next(NULL); and in_plugin = in_plugin->next; by in_plugin =
   av_codec_next(in_plugin);

So these changes can be pusshed upstream
