While the Apple documentation currently seems to indicate that we should
set RealTime to True, it appears that this may be causing issues with
the encoder not being able to meet the target frame rate. Both FFmpeg
and Handbrake have recently explicitly set this value to False, and
preliminary tests seem to indicate that setting this to false in OBS has
favorable results.
The encoder property kVTCompressionPropertyKey_ExpectedFrameRate is a
hint to the video encoder. Since frame rates can be fractional, let's
use a float here instead of an int.
OBS no longer supports building on OSX. The minimum version of macOS
that we support is macOS 10.13. We can safely remove this 10.8
compatibility code.
For some reason, SetWindowDisplayAffinity can make windows visible even
when it sets the same value for affinity that GetWindowDisplayAffinity
reports. Possibly an API bug as this is probably not a widely used API
yet?
Fixes a weird window with no size appearing when browsing for files on
Windows.
Update the libaom and SVT-AV1 versions and also apply several
cherry-picked commits to FFmpeg for SVT-AV1.
The libaom commit is what will be used by obs-deps once
https://github.com/obsproject/obs-deps/pull/90 is merged.
The audio capture callback's mute parameter internally respects the
push to talk/mute state, whereas obs_source_muted() and the "mute"
signal don't. This resulted in meters looking entirely unmuted even
though both monitoring and output were not receiving audio.
OBS_PROPERTY_GROUP creates neither a widget nor a label, causing
AddProperty to create a default one. Without a widget, it does not
get attached to the layout, resulting in a memory leak.
This commit also simplifies a bit of the code to avoid repeatedly
testing the same condition.
They detection for this was not checking the n selected items but the
first n items in the list, which would lead to the options being enabled
or disabled based on the whether other items were locked.
Deprecates:
obs_source_addref()
obs_output_addref()
obs_encoder_addref()
obs_service_addref()
obs_scene_addref()
These functions should be considered unsafe and not used. Instead, use:
obs_source_get_ref()
obs_output_get_ref()
obs_encoder_get_ref()
obs_service_get_ref()
obs_scene_get_ref()
These functions return a pointer to the incremented object only if the
object is still valid, otherwise they will return null, indicating that
the object is no longer valid or is unsafe to use.
The reason why this is being done is because certain third party plugins
seem to be using addref, and are somehow managing to call addref on
sources that have already been fully released. For the sake of safety,
almost all usage of these functions within OBS have also been replaced
as well.
This prevents double destroys from happening on sources and causing
crashes. If someone's doing a double destroy it'll probably crash anyway
but at least we'll know what happened if it does. (Jim note: I suspect
third party plugins are calling addref on sources when they shouldn't
be. Either that or we're missing something ourselves, but I suppose
we'll see.)
This uses the SetWindowDisplayAffinity API to hide windows from capture
applications (including OBS). This is not perfect - internal windows
such as context menus, combo box dropdowns, etc will still be displayed.
Even with these limitations, it should help people with single monitors
capture content with less interference from the OBS window.
This implementation is for Windows only but the code is generic enough
that adding other platforms should be straightforward.
