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. ```pascal 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} ```
