OBS Studio 28 no longer supports Windows 7, 8, or 8.1, and Qt 6 will
fail to run on those versions. Users on those systems being offered the
update will end up in a state where OBS will not run if they install the
update. Let's prevent the updater executable from running on those
versions to avoid that scenario.
Do to multithreading the update process, files of the same hash can
sometimes collide due to race. Ensure the filenames are all unique by
appending an incremented value for each file.
With the addition of server-side release rate control, having the server
know if the update check was manually initiated can allow it to deliver
the update to the user even if they would normally not be eligible.
Windows only.
Request / response latency dominates the download time of small
files and patches, especially the locale files. Increasing this to
4 doesn't consume many more resources and basically doubles the
download speed, especially on higher latency connections.
Unfortunately WinHTTP doesn't support multiplexing with HTTP2, but there
is still some minor benefit to enabling it. Windows 10 21H1 will enable
TLS 1.3 client support in Schannel, so let's get ready for it.
On a modern Windows OS, you can rename an in-use file despite not being
able to write to it. With the introduction of the virtual camera, it is
now quite common that users will have in-use files when updating. This
commit renames in-use files, allowing the new version to be installed.
Upon a reboot, the previously in-use file will be deleted.
Adds a virtual camera button to the main user interface. If virtual
camera is not installed, it will not add the button. On Windows, it
detects whether the virtual camera filters are properly registered, and
will only add the button if the virtual camera filter is confirmed
registered.
Also adds a virtual camera option to the auto-configuration wizard,
which will just simply set the user's resolution/scale to 1920x1080 at
30 FPS.
In rare cases, "runas" would somehow launch the updater as a non-admin user
again, resulting in a loop where the updater constantly spawns processes.
Fixes https://github.com/obsproject/obs-studio/issues/2984
As of 3.17 using find_package_handle_standard_args checks that the name
of the FindXXX file and the first argument are the same case.
Some modules used non-standard variables or the old singular variables
instead of plurals. This normalizes variable usage to the new-style.
Some CMakeLists.txt did custom error checking instead of propagating
find_package errors. These were changes to call find_package with
REQUIRED or without QUIET where needed and shortens the custom status
messages. This helps users who want to enable that functionality see
what precisely wasnt found.
A long standing lack of synchronization on the elevated process handle
made the non-elevated process always exit, so the updater would assume
it was started elevated and launch OBS from the elevated context.
Also applies the altered working directory to the non-elevated code
path so it can find the OBS executable properly.

The program can get stuck waiting for the browser within a event queue,
so instead mark that the program is closing, do it in a separate thread,
signal the window when it's finished, and then check whether it's in the
process of closing before actually showing the dialog.
The current updater code won't prompt the user if an output is active or
if game capture is in use. These are both fairly common situations to be
in as soon as OBS starts up - for example, the NDI and VirtualCam
plugins both start outputs automatically, and a game capture source will
hook if the game is open.
It should be fairly obvious to a user that OBS will be closed when an
update is installed. Given the low frequency of game capture updates,
the risk of an update encountering in-use files is also very low, and
the standalone updater UI already shows a prompt should this happen.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
This can take a while on a hard drive since it hashes the entire OBS
installation, show a undetermined progress marquee to avoid users
thinking that the updater has frozen.
(This commit also modifies UI)
Adds a universal function for determining whether video output is
currently active, rather than having to use video_output_active() on the
value returned by obs_get_video().
