I'm currently playing with modified ximagesink that does XGrabPointer() in order to receive the mouse events occurred outside of the window and send them to the navigation interface. The pointer positions usually have positive coordinates, but it could be negative with that change. When the ximagesink handles XEvent that contains a negative pointer coordinate, it incorrectly generates the GstEvent that contains an extremely large positive pointer coordinate. This is because the negative pointer position in XEvent is incorrectly converted from signed to unsigned and passed as an argument to gst_navigation_send_mouse_event() which causes implicit conversion from integer to double. So the pointer position in the received XEvent and generated GstEvent are completely different. This potential problem does not seem to be a real problem with unmodified ximagesink but there is no reason to leave it as is. This also fixes xvimagesink that has the same potential problem. https://bugzilla.gnome.org/show_bug.cgi?id=791140 |
