This changes the return type for getting the filter index from a
size_t to an int. This makes it easier for developers to use,
as an invalid index just returns a -1.
The frontend API was never explicitly cleaned up which has lead to
several crashes from plugins continuing to call it even after OBS itself
has been destroyed. We now destroy the API after the exit event, so
further calls by plugins will be no-ops instead of potentially accessing
destroyed OBS state.
This also required some changes to our own use of the API, as we relied
on the OBSBasic destructor to clean up some callbacks, by which point
the API should have already been destroyed.
Linux QSV drivers have varying capabilities depending on if the
free/non-free Intel drivers are installed. This means we cannot safely
expose QSV in simple mode as users may be unable stream without changing
to advanced mode.
The macros `YOUTUBE_ENABLED`, `RESTREAM_ENABLED`, and `TWITCH_ENABLED`
are not defined when the associated features are not enabled.
When the code was originally implemented, there were definitions to set
`0` if the feature is disabled. However a later commit 349372b removes
the definition. Now, the use of `#ifdef` is better than just `#if`.
Instead of actually removing the file, simply rename it to the .bak
version which OBS ignores in most cases. That allows users to recover
accidentally deleted collections more easily, while only taking up a
few kilobytes of disk space at most.
A bug which was technically introduced in df446c3f6e: the author
assigned video mixes to the virtual camera and did not realize you have
to wait for full capture stop with the "deactivate" signal rather than
the "stop" signal. This situation is understandable because these
signals are likely confusing and need more documentation.
The way an output works when it stops is it has three stages:
- "stopping", which is the moment the user themselves stop the output
- "stop", when the output's implementation has stopped and returns
success or an error code
- "deactivate", when the output inself (not the implementation) has
fully stopped capturing encoded or raw frame data after the
implementation has stopped. This is done in a separate thread,
end_data_capture_thread(), for performance and data race reasons, and
is when it's "actually fully stopped for real this time"
(Lain note: I sincerely apologize for this confusing signal design)
The author of df446c3f6e was likely confused as to why they could not
destroy the video mix in the "stop" signal without triggering a race
condition in end_data_capture_thread(), and instead decided to make a
workaround to clear the video mix set to the output before destroying
the video mix. Unsetting the video mix I'm guessing *seemed* to fix the
problem for them at the time, and destroying the video mix separately
after that automatically stops capture, so it *technically* worked
because the deactivate thread cannot be called until the
implementation's stop signal has executed. However, it was still the
incorrect way to handle the problem, because it circumvents the output's
mechanism for deactivating the frame data capture by destroying the view
instead.
The reason this was the incorrect way to handle the problem became
exposed in 7cd7ca80f8, when tytan made it so it uses the main video mix
under certain circumstances. The main view is special and cannot be
destroyed, so the mechanism to stop frame data capture that the
virtualcam was using before failed, and raw frame data capture continued
perpetually until the end of the program erroneously.
This fix solves the bug by using the "deactivate" signal rather than the
"stop" signal, thus allowing the output to fully end its data capture
and *then* destroy the video mix.

Unobfuscated secrets require the hash values to be set to 0, by default
CMake will treat 0 as a falsy value. This commit adds support for
_either_ 0 _or_ a valid hexadecimal hash.
YouTube Live now supports 5.1 surround sound.
The surround sound warning in Settings has been updated to reflect that.

When changing audio channels, sample rate, or audio buffering settings
multiple times by hitting `Apply` button, the internal `changed` state
got corrupted. To avoid this, set the changed state when changed
something, but do not clear the changed state.
Creation of Info.plist files through Xcode is more canonical and
future-proof, as it will automatically pick up changes/updates
introduced by Apple. Non-standard keys can still be added via a
template file, which will then be extended by Xcode with the default
keys.
The branch is never taken and the code acts as documentation for a
(possible) future use case. According to YAGNI it could be removed
entirely, wrapping it in a comment is the less destructive approach.
