Fixes a race condition where a hash value could be overwritten from
different threads, causing corruption

If the tray is disabled in settings, we no longer allow the command line
parameter to override it and create a tray icon regardless. This matches
the behavior in the UI, where "minimize to tray on startup" becomes
unavailable if the "tray enabled" setting is unselected.

Remove a few unused variables and other minor changes. No functional
differences. Issues detected by PVS Studio.

This is a temporary fix as to not to delay the release, and will need to
be replaced with AddValue in future versions.

unlike other YUV based formats nv12 chroma plane has the same padding as

Due to the fact that a global was used on GenerateSpecifiedFilename to
save the remux file name, when a screenshot was made, it would overwrite
the filename being remuxed, because screenshots use the same function to
generate filenames as well.

This solves that problem by removing the global and the changes to
GeneratedSpecifiedFilename, and isolating that to the output handler.

Coincidentally, this bug probably also happened with replay buffers
under certain circumstances.

Closes obsproject/obs-studio#3498

Remove support for Vista as the platform update is no longer available
from Microsoft. Allows retrying certain error conditions such as when
OBS is already running. Moved in-use file checks to after the install
directory is selected. Added some comments.

deps/media-playback: Fix current time at not standard speed

frontend-tools: Free xdisplay on Linux auto scene switcher

This fixes an issue where someone might mistakenly try to change an
audio/video encoder before the output is complete.

The xdisplay in the Linux scene switcher was never closed
when OBS exits.

mac-capture: show actual windows in Window Capture sources

win-dshow: Set current working directory in VirtualCam scripts

rtmp-services: Added Mux to services.json

This change adds both Mux's RTMP and RTMPS endpoints to
the list of prefilled services.

Allows modifying the output OBS_FRONTEND_EVENT_STREAMING_STARTING.

This object should not always be created on startup. Instead, only load
it specifically when the user wants to load it.

This fixes a freeze some users were experiencing due to the text widget.
Unfortunately, it is not yet known how that freeze occurred with the log
viewer, so for the time being do not load the log viewer object unless
explicitly created.

linux-v4l2: Fix boolean and menu control types

Previously, changing boolean or menu settings would send incorrect
values to the ioctl.  This change fixes the support.

Fixes the browse button in the remux file dialog not having the proper
style applied. This is a bit of a workaround because it is still unknown
why the button was white.

obs-scripting: Fix script_path() python memory corruption

Returning PyObject with borrowed reference will result in double free
and/or use after free issue.  Issue seen as crash when running Python
script calling script_path().

UI:Fix crash on log upload

Earlier code calls enable on platform specific UI elements resulting in
crash since these elements are deleted on Linux.

CI: Remove clang format Mac check

CI: Update notarisation workflow for Github CI

obs-ffmpeg: Add missing translable string for "Profile"
