gstreamer and Windows

I modified the .../fpcupdeluxe_trunk/fpcsrc/packages/gstreamer/src/gst.pp a little and now it works on Windows. I tested it on Linux with wine.

const
//  gstreamerlib = 'libgstreamer-1.0'; {Setup as you need}
{$ifdef Linux}
gstreamerlib = 'libgstreamer-1.0';
{$endif}
{$ifdef Windows}
gstreamerlib = 'gstreamer-1.0-0.dll';
{$endif}
