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.

New profile state is similar to first start: settings are wiped, encoders
not setup. It may make sense to show the auto configuration wizard when
a new profile is made as well.

There is a checkbox option to show the wizard. If a profile is created
with the checkbox off, the checkbox will remain defaulted to off next
prompt.

Also adds a tweak to the brew update which _might_ fix Azure CI.

This also enables hardware decoding by default for stingers.

Note: per c2a2bc5e this will not affect
webm files with alpha.

Fixes #3357

Same changes as 0c0ffb34

AdvancedOutput::AdvancedOutput(OBSBasic *main_) lacked
a proper event handler connection

OBS already handles a couple of different audio formats, this expands
alsa input to try these additional formats for devices with weird format
support.

fixes #3547

Detect other instances of the obs by inspecting running applications
with same bundle ID.

fixes: #3053

RNNoise symbols may collide with external ones provided by
libcodec2.so which FFMPEG may pull in automatically. Changing
the visibility of these symbols will guarantee the use of the
internal ones and not pick some (potential incompatible) from
outside.

fixes #3561

Helps prevent Stats dock from resizing OBS when long text is set.

For some reason, currently unknown, FFmpeg logging has to be set to
something in order for HLS to not fail on Windows, even if it's just an
empty function.

(Author comment: I don't feel comfortable not knowing why, my theory is
that FFmpeg has an issue with this internally with HLS on Windows
related to logging or how it's trying to log, I have absolutely no idea
what's going on and if someone can enlighten me or debug FFmpeg itself
it'd be real nice to know why.)

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.

Fix #3514 on MacOS and Ubuntu.

For game capture, hook DXGI release function to release D3D objects if
the related swap chain is also being destroyed.

An added bonus is that the game capture hook will handle swap chain
recreation for applications that don't use ResizeBuffers.

Add HLS streaming output

Add and register an obs_output_info struct called
ffmpeg_hls_muxer. It uses ffmpeg's HLS muxer to stream output.

Add threading and buffer to reduce skipped frames.
Also add frame drop logic when there are too many packets in the
buffer for congestion control.

(Jim) Allows the ability to use stream keys with ffmpeg-mux -- this will
enable the ability to use it with certain services (such as YouTube)
which allow different protocols (such as HLS)

(Jim) Allows the ability to specify mux settings directly on the
output's structure itself rather than just via settings. This is useful
for network-based muxer outputs (such as HLS).

(Jim) printable_file allows the ability to keep a separate string for
logging which will not contain things like stream keys when used with
outputs such as HLS.

Allows the ability to get the stream key for YouTube regardless of
whether using the normal RTMP or HLS versions of YouTube.

(Jim) Allows the ability to get a link from the service's settings about
a specific service selection the user chooses and display it as a "More
Info" button that the user can click to find out more information about
that particular service.

(Jim) Allows the ability to use it for more output types.

The frontend API event OBS_FRONTEND_EVENT_REPLAY_BUFFER_SAVED was not
being triggered when hotkeys were used because it was only set to
trigger when the replay buffer button was clicked, not when a hotkey was
used. This fixes it so that the frontend event sends a signal to the
frontend so that hotkeys will actually work.

New events must go at the bottom of the list, not at the top, otherwise
ABI will be broken.

* obs-frontend-api: add the event of saving replay buffer

Add OBS_FRONTEND_EVENT_REPLAY_BUFFER_SAVED as given by RFC 33

* UI: Emit the replay buffer saved event to the api

Send the OBS_FRONTEND_EVENT_REPLAY_BUFFER_SAVED to api (as in rfc33)

* docs/sphinx: Add replay buffer saved event

Documentation provided for OBS_FRONTEND_EVENT_REPLAY_BUFFER_SAVED (RFC33)

Adds the virtualcam GUID to win builds on GH actions and azure.
