There's a new group trying to make GStreamer work easily on all platforms:
http://gstreamer.com/That might be good opportunity to get more out of John's GStreamer plugin :)
So far the plugin has been pretty much Linux-only. John got it to work on OSX while developing, but that never went "into production".
There are two open-source companies behind this, Fluendo and Collabora. I know some folks at Collabora because they are also behind the OLPC project's networking architecture. Good guys. They promise this will be a staple API. Sounds good all around to me ...
