Allows the customized UI elements used by OBS Studio to more cleanly
be integrated into consumers of the same elements, mainly frontend
plugins in the main source tree.
find_qt was necessary during the transitional period between Qt5 and
Qt6. With Qt6 being the only supported Qt version (for open source) for
the time being, code complexity can be reduced for easier maintenance.
When running an Output Timer multiple times, multiple signal-slot
connections would be made with the corresponding output stop event
functions. This would cause later Output Timers to terminate
unexpectedly early, due to the stop functions having been called
repeatedly on previous Output Timer runs while outputs were stopping.
There may still be an underlying bug with calling stop on outputs
repeatedly, but this change at least ensures that Output Timers only
call their stop functions once.
Didn't realize OBS could output both program and preview views at the
same time with multiple devices.
Also remove render callbacks earlier on stop to avoid use-after-free.
Creation of Info.plist files through Xcode is more canonical and
future-proof, as it will automatically pick up changes/updates
introduced by Apple. Non-standard keys can still be added via a
template file, which will then be extended by Xcode with the default
keys.
The `done` event does not emit a `closeEvent`, but saving is only
implemented in that event handler. Changing this to `close` correctly
triggers the default QWidget event and thus settings are saved.
Use the render path that preview uses for non-preview rendering, which
uses the GPU to rescale rather than the CPU and pulls the image from the
GPU before pixel format conversion happens. This means it's no longer
necessary to select BGRA to use the keyer anymore.
Mapping a GPU resource for CPU read immediately after GPU write creates
a large stall on the graphics thread. Use a small circular buffer, and
read the oldest frame instead.
The script and scene switcher lists were not being styled.
This also sets the spacing to 1 for the filter, script, scene
switcher and properties view lists, the same as other lists.
