play: Missing g_object_notify signals
Originally GstPlayer
library had used g_object_notify_by_pspec
to notify about changed values on its properties. New GstPlay
lib unfortunately lost this ability along the way, which makes is harder to use with toolkits that allow binding GObject properties e.g. GTK
.
This also introduces API incompatibility with all apps that were using g_object_bind_property
with player props and thus depend on them.
