hi guy:

I am porting a project from linux to windows and i chose cygwin .
The project  receive video and audio by gstreamer.
But it only play audio but the video is fail.
GStreamer had tell me WARNING message: 

GStreamer-WARNING **: Failed to load plugin '/usr/local/lib/gstreamer-0.10/libgstcoreelements.dll': No such file or directory

The libgstcoreelements.dll be existed in /usr/local/lib/gstreamer-0.10/

I guess the WARNING is key point but I don't know how to fix it.
