The pipeline ending with ... ! gdkpixbufsink is not supposed to write
image files, it will create GdkPixbuf objects for the application (which
the app may access either via bus messages or using the last-pixbuf
property). If you want a file, you need something like 

 ... ! jpegenc ! filesink location=foo.jpg

or

 ... ! pngenc ! filesink location=foo.png

You tried? But didn't succeed?

No, just gdk-pixbuf (which is in the gtk+ tarball, but does not depend
on either gtk or gdk; if the element shows up in gst-inspect, it should
work).
