Here's one example:

http://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/sys/xvimage/xvimagesink.c#n2730

The xvimagesink implementation is about as complex as it gets, because
the xvimagesink supports scaling and offsetting of the video into the
output surface. The navigation_send_event implementation reverses those
operations, so it takes mouse clicks in the window coordinates, and
converts it back to a mouse click coordinate within the original video.
