On windows, when a source has only audio (no video) yet is marked as
capable of both video and audio, it would be programmed to expect a
video frame to synchronize with. This fixes that potential issue by
detecting whether any video is actually playing or not.
When kaspersky is installed on windows 7, FindWindowEx will fail to find
any windows due to apparently being blocked by kaspersky, so detect when
that happens, and fall back to GetWindow instead if it does.
This is mainly to give visual feedback to those affected by NVENC not
working with older driver versions. Currenlty obs fails silently which
could go unnoticed for users who are using hotkeys as well as confuse
users who are not trained to read their logs when issues occur.

Due to crashes being caused by hardware acceleration in the media source
on mac, disable hardware acceleration of the media source being on by
default for the time being.
In transitions, because the 'to' and 'from' are always rendered to
textures, the end result will always have premultiplied alpha. This
would cause alpha to have blackish edges during transition, and cause
semi-transparent images to appear darker than they were supposed to.
To replicate, simply set the transparency of a source to 50%, then
transition between that scene and another scene. The source will appear
to "pop" in and out unnaturally due to the premultiplied alpha effect of
the render targets.
To fix this, the solution is to simply convert premultiplied alpha to
straight alpha in the transition pixel shaders.
When the OBS signal is triggered for these widgets, the invokeMethod
could cause the thread to stall, which could make it wait much longer
than necessary to output audio data. When that happens, it causes audio
monitoring to get backed up and get unnecessarily delayed, as well as
cause general audio buffering in libobs to increase unnecessarily.
A simple fix both in terms of preventing that stall and improving UI
performance is to not call invokeMethod to update the widget each time,
and then instead have those widgets update themselves via a timer at a
specific interval.
Adds functions to turn on audio monitoring to allow the user to hear
playback of an audio source over the user's speaker. It can be set to
turn off monitoring and only output to stream, or it can be set to
output only to monitoring, or it can be set to both.
On windows, audio monitoring uses WASAPI. Windows also is capable of
syncing the audio to the video according to when the video frame itself
was played.
On mac, it uses AudioQueue.
On linux, it's not currently implemented and won't do anything (to be
implemented).
Twitch added the following ingests:

The following ingest server is no longer listed in hitbox' API:

YouTube does not list a requirement that states that only the main profile can be used.
This allows for color grading based on a color look-up table. Commonly
used to color correct and/or grade video that has been shot in Log.

This algorithm reduces scaling distortion on the center of the image
when scaling from ultrawide to wide.
(Jim: edited effect files to prevent an impact in performance for
standard scaling. Now effectively generates an extra pixel shader, and
the extra code is only applied to the DrawUndistort technique, while the
original Draw technique is unaffected due to the compiler automatically
removing unused code branches via the hard-coded boolean value)
