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.

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.
Makes Visual C runtime libraries consistent across
Debug/MinSizeRel/Release/RelWithDebInfo, rather than just changing those
flags for RelWithDebInfo. Also adds /Zl for statically linked
libraries.

It would only check whether it should download a package if the 32bit
version existed. This would cause it to not download all files
correctly to update 64bit installs (post 22.0.1).
Saves a bit of bandwidth when the update module just updates binaries
for the specific architecture being updated. Especially true when
libcef needs to be updated.
This is just for the update module -- allows us the ability to
seamlessly update the program to VC2017 and seamlessly install Visual
C++ 2017 redistributables without potential issues that could be caused
by GPL usage for the update module.
On Windows 7, WinHTTP defaults to using only SSL3 and TLS 1.0. The
obsproject.com server was updated to remove TLS 1.0 support and
this has caused updates to stop working on Windows 7.
Currently if a file is partially written to (eg, the file is opened for
writing but the write fails), the updater won't correctly roll back to the
previous version, leaving the OBS install in an inconsistent state.
We now track failed installs or hash failures on patched files with a new
STATE_INSTALL_FAILED state and properly roll back on errors.
When updating large files such as libcef, the patching process can take a
decent amount of time. Previously the progress bar would remain at 100%
after completing the downloads, so the user may think the updater has
frozen. Now it shows the process of the install / patching process.
