Buffering inside libobs is enabled by default and it causes latency of
video. This commit provides a property to switch the buffering.
Since the latency of the buffering changes every startup, set the
default to unbuffered mode, though the previous implementation was
enabled buffering.
This converts the advanced audio window to use
a ui form, so it is easier to modify in the future.
This also fixes sizing issues with the control widgets,
as before the audio tracks would be clipped, because the
widgets in the window were too wide.
When the mode is set to auto, the API sometimes send frames with 0x0
size. Without filtering such frames, which causes libobs to output error
messages.
This change fixes an issue with the CMIO DAL plugin where the CMIO
subsystem would log multiple errors when starting the virtual camera,
due to certain properties that could not be set (frame rate and format).
For now, we just ignore the assignment, but mark the property as
settable to suppress the error messages that are reported by the CMIO
subsystem.
This change fixes an issue in the Mach server exposed by the macOS
virtual camera for OBS, where it would not invalidate ports that were
disconnected by the remote application, causing sporadic crashes.
These crashes can be reproduced in the previous builds by opening the
virtual camera in a remote application and closing the application
(without stopping the virtual camera).
This change updates the implementation of the mac-virtualcam plugin to
not use any global state and instead rely on the state object that is
passed by the OBS module system.
This approach is similar to the virtual camera implementations for Linux
and Windows.
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.
Sometimes when reconnecting the internal RTMP data is not cleared
(particularly the TLS data). This can cause TLS data to carry over from
one connection to another, causing issues with the secondary connection.
Due to a bug in shader parsing, it thinks that because the token
"multiplier" is used here, that the "multiplier" uniform is being used.
This is a workaround for the issue because fixing the parser is probably
going to be much more annoying than just working around the issue for
now.
In bb6787968, we changed the default behaviour to be strict modifiers
and we consider this to be the correct way. There is no need to change
this from code either, since if someone really needs non-strict
modifiers, they can work around it by setting multiple hotkeys.
Having this option in code just means a bigger maintenance cost, so
we'll deprecate the function and remove it in the future.
