Makes OBS try to close the remux dialog before Clearing Scene data since
in case a remux might still be going on and the user does want to abort
closing OBS.
If a module is not found in context bar, it crashed when resolving
source type name. This is same change as 41367bb2b but fixes
window-capture and display-capture.
Also removes an unnecessary pair of braces.
Visually, the Scale Filtering, Blending Mode & Method, and Deinterlacing
menus are now grouped together, with "Hide in Mixer" being its own group
until a better place for it has been found.
Projector and Screenshot menus have been moved down.
As a related code cleanup, the creation of sourceProjector and
sourceWindow has been moved down and partially inlined.
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.
This limits the length of the name label in the advanced audio
dialog to 80 characters, so the dialog doesn't get too wide. If the
name is truncated, "..." are added at the end of the label, and the
label's tooltip is set to the full name of the source.
This hooks the platform specific events in order to close the obs
display more accurately. Earlier attempts on hooking visiblity, but Qt
does not ensure that visibility is changed before the surface is
destroyed. So we ended up racing with the EGL driver and on some
drivers if you lose the race they hang.
Also only force display creation if the display is actually visible.
When a source type is not video/drawable (or is missing) this would
force the display to be created for the blank window and also hang.
Finally force closure of the preview displays during scene cleanup to
avoid similar ordering issues in Qt. Qt has even less order guarentees
during close and we are sure that displays are no longer needed at this
point in the UI.
Adds %s which replaces the keyword with the current unix epoch time.
The %s keyword is common in languages like PHP and Python, and even
some C implementations, but it is not standard so this is a fallback.
