When mplayer2 is paused - * it will asynchronously poll for events using select. This works correctly on - * Linux with X11 since the events are notified through the file descriptors - * where mplayer2 is listening on. On the other hand, the OSX window server - * notifies the processes for events using mach ports. - * - * The code below uses functionality from Cocoa that abstracts the async polling - * of events from the window server. When a Cocoa event comes in, the polling is - * interrupted and the event is dealt with in the next vo_check_events. - * - * To keep the select fd polling code working, that functionality is executed - * from another thread. Whoever finishes polling before the given time, be it - * Cocoa or the original select code, notifies the other for an immediate wake. - */ - -#include "cocoa_events.h" -#include "video/out/cocoa_common.h" -#include "talloc.h" - -#import <Cocoa/Cocoa.h> -#include <dispatch/dispatch.h> - -// Bogus event subtype to wake the Cocoa code from polling state -#define MP_EVENT_SUBTYPE_WAKE_EVENTLOOP 100 - -// This is the threshold in milliseconds below which the Cocoa polling is not -// executed.
