These defs inadvertently redefinine `std::strtoll` in C++ code
that includes the header, causing lots of problems. They only
serve to provide compatability with very old MSVC versions.
As such, they can just be removed entirely.
Fixes a long-standing issue with Dynamic Bitrate where the RTMP output
thread could try to reconfigure an encoder while the encoder is in the
middle of encoding. x264 seems to handle multithreaded calls well, but
NVENC would deadlock in this situation with no error visible to the
user.
These local copies of CheckForPthreads.c and FindThreads.cmake override
the ones included with CMake. These versions create CMake::Threads, but
Qt6 expects Threads::Threads created by CMake 3.1+. These local versions
seem to be based on old copies from CMake from late 2014 with some
customizations. Let's just use the built-in ones that CMake ships.
This commit also changes CMakeLists.txt files in UI and libobs to
require and link to Threads::Threads.

Since the darray `sys_include_dirs` is an array of `char *`, it is
required to take a pointer to `char *`, that is `char **`. However,
`char *` was passed.
Since this function never called, another fix is removing entire
function `cf_preprocessor_add_sys_include_dir`.
This fixes a crash that could occur during freeing of sources, as the
audio subsystem was destroyed before sources were released. If a source
had monitoring enabled, it would try to lock a mutex that has been
destroyed, resulting in a crash.
Freeing audio after obs_free_data was also not a solution, as the main
view is freed in obs_free_data, and the audio subsystem is still running
and trying to lock the main view channel mutex which has been freed.
This seems to be the best middle ground, making sure the audio subsystem
is stopped so it no longer tries to access the main view channel, then
freed after obs_free_data.

When playing video, OBS can overflow and crash, or render video edges
incorrectly if the video resolution does not divide into 2 for trivial
chroma subsampling. This is fixed by rounding chroma plane sizes up
instead of down, and maintaining that through the video pipeline.
XDG Portals provide a plethora of features meant to be used inside and
outside sandboxed environments. OBS Studio currently uses portals to
implement Wayland-compatible monitor and window captures.
However, OBS Studio performs another action that can be done through
portals: inhibit the screensaver. Under the Desktop portal (the same
used by the captures mentioned above), there is an "Inhibit" portal
that provides session inhibition.
Add a new portal-based inhibitor. This inhibitor is only used when the
Desktop portal is available and running; the previous D-Bus implementation
is used in the absence of the portal. Because it's basically another set
of D-Bus operations, wrap the new portal inhibitor under the HAVE_DBUS
call too.
In order to do linear-correct filtering cheaply when scale filtering is
disabled, we need to know whether or not texture coordinates will always
sample from texel centers. This can be computed at the scene item level
relatively easily, and passed along to sources when rendering. Scene
items will use obs_source_set_texcoords_centered to set hint status, and
sources will use obs_source_get_texcoords_centered to retrieve it.
There is currently no way to enumerate *all* sources in OBS. Only
inputs and scenes have a way to be enumerated. Some applications
like obs-websocket have features that need to take advantage
of enumerating all sources in order to function properly.
The proposed way to handle plugin distribution
through Flatpak depends on these directories to
be read. It goes as follows:
1. Flatpak's extension point merges the 'lib'
and 'share' directories at /app/plugin
2. Plugins prefix their install paths in the
Flatpak manifest to /app/plugins/<plugin name>
3. OBS Studio lists /app/plugin as one of the
search paths in OBS Studio code
This commit implements the third step of this
process, which is the only one that actually
involves OBS Studio itself.
With that, it is possible to distribute plugins
as Flatpak extensions, which in turn allows them
to be listed at app stores such as GNOME Software,
elementary's app store, and KDE's Discover.

When size of source_info_t is larger then current structure, memcpy
overruns. Size check is moved before the memcpy.
HANDLE_ERROR macro copies info to data but data is not used. When
calling free_type_data and type_data, the member of data should be used
to ensure the free_type_data is not out of bounds.
Add gs_image_alpha_mode enum for requested alpha handling: straight,
premultiplied with SRGB conversion, and just premultiplied. Both
premultiplied settings behave the same if the image is not SRGB, linear
is assumed.
Add gs_image_file3_t to store the alpha mode.
Add srgb.h file with helper functions.
Clean up vec4.h to use helpers, and remove unused functionality.
Update FFmpeg image loader to perform premultiplication on load.
Add OBS_SOURCE_SRGB to indicate sources that support SRGB rendering. We
can use this flag to know which sources do not know how to handle SRGB,
and disable accordingly inside obs_source_main_render().
We can also use this flag to clean up the filter interface and remove
the SRGB-specific functions. We also need to disable direct rendering if
the filter source wants to render SRGB, but the parent source does not
support it.
Scenes and groups are marked as having SRGB support, and those are
internal sources that we control.
