SCK's application list has one entry with empty name and bundle ID which
belongs to WindowServer. This is not worth exposing since an empty entry
would confuse users and nothing would get captured if selected.
Marking a source as deprecated will make it harder for users to find
when creating a new source. We don't currently plan on removing
traditional display and window capture, however ScreenCaptureKit will be
the preferred capture method going forward.
on the capabilities of audio capture refer to the documentation https://developer.apple.com/documentation/screencapturekit/ or watch the session "Meet ScreenCaptureKit".
Currently audio capture typically happens via virtual devices set up with 3rd party products. This requires additional installation and configuration by users.
Including the audio with the existing CMBuffers will make it easier to manage audio sync with video frames. Additionally, you can capture distinct audio tracks from multiple apps at once,
like a call with friends + screen content.

Tested with multiple games + Discord, FaceTime, Apple Music and Safari tabs playing audio content.
* Bug fix (non-breaking change which fixes an issue)
* Performance enhancement (non-breaking change which improves efficiency)
* Additional control over what audio content to capture
* Logic to manage audio & frame sync
Replaces the current implementation of Window Capture, which uses Core
Graphics to render a bitmap raster, with one that accesses the window's
CGImage bitmap directly, blits it, and hands that off as a frame to OBS
instead.

The timestamp returned by mHostTime in the AudioTimeStamp structure
is the current timestamp equivalent to mach_absolute_time(), which
is relative to the machine's time base. In order to convert this
to milliseconds, it's necessary to get the host's timebase with
mach_timebase_info() and scale the timestamp accordingly, since
the rest of the timestamp synchronization code expects the timestamp
to be in milliseconds.
This is effectively equivalent to the code which was previously in
libobs/util/platform-coca.m, but must be applied here instead.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
