Norihiro Kamae 7b4ae8611c libobs: Fix da_push_back taking a wrong type of item
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`.

Richard Stanway 3dbfa4919a libobs: Add stop_audio function, change shutdown order
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.

Fixes https://github.com/obsproject/obs-studio/issues/4409

jpark37 8440a53da3 libobs: Round up chroma sizes for odd resolutions
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.

Georges Basile Stavracas Neto 99559aab5a libobs: Add portal inhibitor
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.

jpark37 7c72fd1d4c libobs: Plumb texcoord hint to reduce GPU cost
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.

tt2468 53a8a326da libobs: Add obs_enum_all_sources()
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.

Georges Basile Stavracas Neto 712478f48c libobs/nix: List Flatpak search paths
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.

Norihiro Kamae 5e44e6412a libobs: Fix memory overrun if libobs version mismatches
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.

jpark37 ae7718a765 libobs, obs-filters: SRGB backwards compatibility
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.
