NSApp is only an Application when initialised from mpv itself. when used
via libmpv an Application is never initialised and mpv would always
immediately exit.
make the retrieval of the vo and mac options static so they can be
retrieved in all cases.
Fixes#12518
Not all deprecated symbols were removed. Only three events were removed for now
since these are not used internally.
This bumps the library version to 2.0.
the pointer used to initialise the respective structs is only guaranteed
to be alive within this constructor. the struct itself is used later and
the data it points to, is not guaranteed to be the same.
to fix this we define a scope that pointer is definitely valid and use
it within this scope. a helper function was added to get the pointers
for several data at once. otherwise we would need to nest
withUnsafeMutableBytes several times, which would make it hard to read.
remove the libmpv observer for the macOS specific options and use a
config cache + change callback for runtime changes. this is also a
preparation for new backends and generalises even more, since libmpv
functions can't and shouldn't be used in usual vo backends. for feature
parity the config cache is used.
move all backend independent code parts in their own folder and files,
to simplify adding new backends. the goal is to only extend one class
and add the backend dependent parts there. usually only the (un)init,
config and related parts need to be implemented per backend. furthermore
all needed windowing and related events are propagated and can be
overwritten. the other backend dependent part is usually the surface for
rendering, for example the opengl oder metal layer.
in the best case a new backend can be added with only a few hundred
lines.
using the MPContext as ta parent was a bad idea and shouldn't be done in
any circumstances there because it only supposed to be for internal
usage. this had the undesired effect that the options group was freed
but still used since the MPContext is freed afterwards.
instead manually free options group.
all the get_property_* usages were removed because in some circumstances
they can lead to deadlocks. they were replaced by accessing the vo and
mp_vo_opts structs directly, like on other vos.
additionally the mpv helper was split into a mpv and libmpv helper, to
differentiate between private and public APIs and for future changes
like a macOS vulkan context for vo=gpu.
