This change removes the unused CMSampleBuffer utility functions that
were still left from the previous implementation. Since we construct the
CMSampleBuffer directly from an IOSurface, we do not need any custom
construction logic anymore, since that is now performed by the OBS
plugin.
This change updates the mac-virtualcam implementation to conditionally
enable conversion of the output video format. Previously, the output
video was always converted into UYVY. However, this conversion exhibits
high CPU usage, as reported in:
https://github.com/johnboiles/obs-mac-virtualcam/issues/102
Therefore, we disable conversion when the selected output format (e.g.,
NV12) is natively supported by CoreVideo's pixel buffers.
This change updates the plugin to support video formats that contain
multiple planes (such as NV12). Such functionality is necessary to
prevent transcoding the raw video data, which is often delivered in a
planar format.
This change updates the mac-virtualcam implementation to pool the
CVPixelBuffers used to share the output frames. This allows the plugin
to recycle the pixel buffers used by the plugin.
This change updates the virtual camera implementation on macOS to
utilize IOSurface to share the output feed with the virtual cameras.
By using IOSurface, we remove the need for copying the frames across
multiple buffers, since they can be shared across Mach connections using
zero-copy.
This change fixes an issue where the DAL plugin would not load due to
not supporting the architecture arm64e. We update the build
configuration to build a universal binary that includes arm64e as well.
See https://github.com/obsproject/obs-studio/issues/6285 for more
information regarding this issue.
Hides the DLog and DLogFunc macros behind the -DDEBUG flag, causing the
logs to only appear in testing environments.
On production build, calls to these macros will result in nothing
happening.
