Matthew Waters	640a65bf96	gst: don't use volatile to mean atomic ... volatile is not sufficient to provide atomic guarantees and real atomics should be used instead. GCC 11 has started warning about using volatile with atomic operations. https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1719 Discovered in https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/issues/868 Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/2098>	2021-03-22 14:34:36 +11:00
Matthew Waters	81d1e16b6b	vulkan: move fullscreenquad object to library ... It's useful and extensible enough to be used by us and other elements	2019-12-04 07:20:27 +00:00
Matthew Waters	a7c2aa473f	vulkan/image: don't rely on weak-ref notifies for views ... Weak refs don't quite work here correctly as there is always a race with taking the lock between find_view() and remove_view(). If find_view() returns a view that is going to removed by remove_view() then we have an interesting situation. In theory, the number and type of views for an image are relatively constant and should not change one they've been set up which means that it is actually practical to perform pool-like reference counting here where the image holds a pool of different views that it can give out as necessary.	2019-11-28 23:27:21 +00:00
