Currently, obs-nix.c is highly tied to the X11 display
server. It includes X11 headers directly, and make use
of X11 functions. Most of the code inside obs-nix.c that
is X11-specific is related to hotkeys handling.
Introduce a new vtable for hotkeys callbacks, that will
used by X11 and Wayland to expose their specific routines.
In this commit, only the X11 hotkeys vtable is implemented.
Move all the X11-specific code to obs-nix-x11.c, and add
a new function to retrieve the X11 hotkeys vtable.
Removes prior attempt to expose libcaption headers which really shouldnt
have public. This instead moves the obs-internal include out of the
public obs-scene.h and into it's implementation.
GS_RGBA, GS_BGRX, and GS_BGRA now use TYPELESS DXGI formats, so we can
alias them between UNORM and UNORM_SRGB as necessary. GS_RGBA_UNORM,
GS_BGRX_UNORM, and GS_BGRA_UNORM have been added to support straight
UNORM types, which Windows requires for sharing textures from D3D9 and
OpenGL. The D3D path aliases via views, and GL aliases via
GL_EXT_texture_sRGB_decode/GL_FRAMEBUFFER_SRGB.
A significant amount of code has changed in the D3D/GL backends, but the
concepts are simple. On the D3D side, we need separate SRVs and RTVs to
support nonlinear/linear reads and writes. On the GL side, we need to
set the proper GL parameters to emulate the same.
Add gs_enable_framebuffer_srgb/gs_framebuffer_srgb_enabled to set/get
the framebuffer as SRGB or not.
Add gs_linear_srgb_active/gs_set_linear_srgb to instruct sources that
they should render as SRGB. Legacy sources can ignore this setting
without regression.
Update obs_source_draw to use linear SRGB as needed.
Update render_filter_tex to use linear SRGB as needed.
Add gs_effect_set_texture_srgb next to gs_effect_set_texture to set
texture with SRGB view instead.
Add SRGB helpers for vec4 struct.
Create GDI-compatible textures without SRGB support. Doesn't seem to
work with SRGB formats.
This function determines if something is an OBS plugin before attempting
to load it. On Windows, many plugins ship their dependent DLLs alongside
the plugin DLL, so OBS would load things like libcef.dll on startup only
to immediately free it. For other platforms, this is less of a concern
so this function is a no-op for now.
This improves startup time and reduces risk from dependent DLLs
potentially running code with unwanted side effects in DllMain.
Also remove use of deprecated [NSProcessInfo operatingSystem]. It always
returns the NSMACHOperatingSystem.
Also stop parsing [NSProcessInfo operatingSystemVersionString]. The
documentation explicitly says "not for parsing".

Simplify usage of the SIMDe header
This obviates the need for sse2neon as well and fixes compilation of all
plugins that referenced sse-intrin.h on all architectures, not just
arm*.
PulseAudio code needs to be called with the PA lock held. This chiefly
fixes multiple races during stream shutdown:
* If the functions are called without the lock held, deferred event
handling races end up with PA infinite looping on the mainloop, or
asserting, or other badness, as the reentrant calls cause data
structure corruption on the PA side.
* If we don't reset our callbacks, PA might call us even after we
request stream disconnection (since the stream actually getting fully
shut down is asynchronous), and then we dereference NULL pointers from
our userdata etc. PA will keep its data structures alive until necessary
via reference counting, but not ours.
The lock around pa_stream_begin_write doesn't result from any issues I
experienced, but it looks correct; PA doesn't say anywhere that that
function is thread-safe.
Regression introduced by dc4e20500: while the stop detection is pending,
it should still return false so the rest of the discard code can run.
Otherwise, the source audio will remain in the buffer, lagging the
source and triggering audio buffering increases until max audio
buffering is reached.
Similar to 315fbd6 and 6071098, ignore non-fatal errors during the
remux process. It's possible OBS itself writes a file that generates
these errors when remuxed.

Changes the maximum resolution size to a resolution list, and splits the
maximum FPS to its own function.
(Note: ABI has not been modified because the last changes still haven't
been released yet, so it's safe to modify this as long as the changes
haven't been officially released)

Implements obs_service_get_max_bitrate, which allows retrieving the
maximum audio/video bitrates directly rather than being forced to use
the apply method. Makes it a bit easier to get the bitrate values.
Add the content of the XDG_SESSION_TYPE environment variable to
the output log if it is set. This is usually set on modern Linux
distributions and typically carry either "x11" or "wayland" when
run from a desktop environment.
This is independent from the QT_QPA_PLATFORM environment variable
which would allow OBS Studio to run inside a wayland session. The
session type it runs on does have an implication on the behavior of
some plugins like screen and window capture. So having this
information exposed here is extremely helpful for diagnosing
issues.
This obs_service_t object callback was implemented specifically for
services which may have a maximum recommended width, height, and
framerate that needs to be enforced.
Adds a cmake variable (DEBUG_FFMPEG_MUX) which enables FFmpeg debug
output in the ffmpeg-mux subprocess, and if on Windows, shows the
console window of the ffmpeg-mux subprocess so the current output can be
seen.
