Settings would not update properly because obs_source_update() can only
apply the settings value to the existing settings, so it could not
remove values. This change fully erases existing settings and replaces
it with the target settings instead.
Allows the ability to reset (erase) a source's existing settings and
replace them with new settings. This is useful for things such as
reverting to older settings.
For v2 filters, switch Opacity settings from integer [0, 100] to
floating-point [0.0, 1.0] with four decimal places for granular blacks.
Also multiply alpha in shader to maintain precision.
When a change to an audio filter was done, it would create a timer and
wait for no more inputs before saving and adding to undo (this is to
prevent spam from sliders). For some reason, the timer would get
destroyed before the information is saved, preventing it from going on
the undo stack.
Rather than forcing the user to close the advanced audio properties
window in order to obtain an undo/redo action, use explicit undo/redo
actions for each widget change in the advanced audio properties dialog.
This allows the ability to mark an action as repeatable, which when set,
makes it so that it will change only the redo value for the last undo
item in the undo stack within the last three seconds. This allows the
ability to, for example, scroll a spinbox or change a slider value
without creating many unnecessarily duplicated undo/redo actions.
The feature name is "Noise Removal" with that exact capitalization.
"NVIDIA Noise Removal" or "Noise Removal, powered by NVIDIA Broadcast"
are the two valid options for displaying this feature name in the UI.
Removed unnecessary lines from the function. Also if the source happened to be
null, the SetCurrentScene function would be called anyway. Finally, the
UpdateContextBar and api lines were removed, as they are also being called with
SetCurrentScene.
Initializing NVAFX is slow as it has to load large models and can cause
significant impact to OBS' startup time. This moves NVAFX initialization
into a separate thread. NVAFX does not appear to be reentrant across
threads, hence a global mutex is also used to avoid reentrancy issues.
The downside of this change is that the first few seconds of audio after
adding the filter or starting OBS will not be filtered, but this is
unlikely to cause any real-world issues.
Convert incoming straight alpha color to premultiplied at filter begin,
and process premultiplied value at filter end.
If direct rendering is allowed, we assume the input source outputs
premultiiplied alpha. If not, that source will need to be updated.
