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+.
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.
(This commit also modifies the decklink, linux-v4l2, mac-avcapture,
obs-ffmpeg, and win-dshow modules)
Originally, async buffering for sources was supposed to be a
user-controllable flag. However, that turned out to be less than ideal
because sources (such as the win-dshow plugin) were programmed with
automatic control over their buffering (such as automatically detecting
USB 2.0 capture devices and then enabling in those cases).
The fact that it was a flag caused a design flaw to where buffering
values would be overwritten when a source is loaded from save data.
Because of that, this flag is being deprecated and replaced with a
specific function to enable unbuffered mode instead.
Certain types of sources (display captures, game captures, audio
device captures, video device captures) should not be duplicated. This
capability flag hints that the source prefers references over full
duplication.
