8dd20dfd33 introduced an explicit check
for the available macOS SDK, meaning that we can be sure that the macOS
13.1 SDK is available. As such, we do not require ifdef guards for the
availability of functions that are older than 13.1.
These effects can remain enabled between devices (so enabling it on one
device can mean it's later also enabled on another device), leading to
cases of capture cards getting blurred.
Logging that the effects are enabled should make it easier to spot this
in support.
Creation of Info.plist files through Xcode is more canonical and
future-proof, as it will automatically pick up changes/updates
introduced by Apple. Non-standard keys can still be added via a
template file, which will then be extended by Xcode with the default
keys.
Per OBS API documentation, `get_properties` can be used to get the
properties of a source, but also of a source type. The latter would
pass a NULL pointer for a given source.
This adds the necessary change to avoid crashing OBS by passing such
a null pointer.
Direct access to `[AVCaptureDevice devices]` is deprecated since macOS
10.15. An `AVCaptureDeviceDiscoverySession` is to be used instead, which
this PR implements.
When running on older macOS versions or compiling against older platform
SDKs, the deprecated method is used.
PS: The formatting is not proper ObjC style, but that's clang-format's
doing with our current settings.
Some webcams, or other AVCaptureDevices like connected iOS devices which
are supported since 162450c, have an audio output which so far got
ignored.
Now, if supported, the audio will be captured alongside the video. For
existing sources, the properties have a button enabling this; while new
sources have it enabled by default.
This adds additional capture presets, including 3840x2160 and
1920x1080, in addition to the preset "High." These are guarded with
a runtime check using the @available() keyword for macOS 10.15+.
