SetupOutputs is already called at the beginning of the function under
circumstances where it's needed, so remove it from being redundantly
called a second time.

This data isn't typically extremely important to have logged on startup,
and it's already included as part of shutdown.  There may be scenarios
where a program crashes and that information would be lost due to the
fact that the shutdown logging never occurs, but that information is
unlikely to be useful in that scenario.

(Note: This commit also modifies coreaudio-encoder, win-capture, and
win-mf modules)

This reduces logging to the user's log file.  Most of the things
specified are not useful for examining log files, and make reading log
files more painful.

The things that are useful to log should be up to the front-end to
implement.  The core and core plugins should have minimal mandatory
logging.

libobs: Fix possible null pointer dereference

These files were heavily modified but originally written by:
B. Lee <bl4@postpile.net>

Prevents the common problem of injecting in to certain processes and
getting the hook DLL "stuck":
- windows explorer
- steam
- battle.net
- gog galaxy
- skype
- uplay
- origin
- microsoft visual studio
- task manager
- league of legends lobby window
- windows 10 system settings window

Changed the first property of game capture to be a "mode" list (with
"any fullscreen window", "specific window", and "hotkey").

When hotkey mode is set, it'll add a hotkey pair to hotkey settings to
activate/deactivate game capture.  When the hotkey to activate is
pressed, it'll treat the current foreground window as the target window
similar to "selected window" mode; it'll keep trying to capture the same
window even if the window or its application closes/reopens, and will
continue to do so until deactivated via the deactivate hotkey, or until
a new window is set via the activate hotkey.

Allows enumerating IP addresses so you can select the adapter/IP from
which to stream from.

Doing something like '#if TRUE' when 'TRUE' isn't defined is the
equivalent to '#if 0' because the preprocessor evaluates an undefined
macro as 0/false.

This should be checking true or false -- not whether it's defined or
not.

These comments have been added to clean up the code and make it more
clear of what the code is doing.  The code felt a bit messy, and this
should help prevent the original author of the noise suppression filter
from being lost in case he decides to modify/improve the filter.

This variable was always being set to that value regardless a few lines
below.

When buffering audio data, we don't want to buffer audio data that may
be old.  If the audio timing jumps significant and old audio data is
buffered, clear that old data.

The noise suppression filter mistakenly operated on the assumption that
input audio data would always be in 10ms segments, and would crash if
audio data was larger than that size.

Because speexdsp operates on fixed audio frame sizes only, we must
buffer audio data to fit that frame processing size.  This creates a
troublesome situation where you must buffer around that specified frame
size.

The new steps for processing are:
1. Push audio data to input circular buffer.
2. Push number of audio frames and timestamp for that audio packet to an
   'info' circular buffer.
3. Check size of input circular buffer, and while it's equal to or above
   the speexdsp frame size (10ms for minimum latency), pop from the
   input buffer to a temporary buffer (10ms frames) and process it, then
   push that temporary buffer to the output circular buffer.
4. Peek at the front of the 'info' circular buffer.
5. If the output circular buffer frame size is equal or larger than next
   expected number of frames, pop both the info and output buffer, and
   return the audio data with the expected audio frames/timestamp.

Adds the ability to lock the preview so sources can't be edited.  This
feature is typically used in the case where the user wants to prevent
accidentally clicking and dragging on sources.

libVLC doesn't seem to provide full speaker configuration info, so when
downmixing audio from a file that had more than 2 channels, the audio
would sound wrong.

This change makes it so that libVLC does the downmixing to stereo rather
than libobs, just due to that lack of speaker configuration info.

Allows setting a "long" description for detailed explanation of certain
properties that may need them, but don't want to display them on the
user interface by default.

UI: Fix fullscreen projector on Linux

linux-capture: Add OBS_SOURCE_DO_NOT_DUPLICATE to window capture sources

It seems that it is not possible to create multiple OpenGL textures
for the same window. When sources are duplicated in studio mode this
causes window capture sources to become black. The
OBS_SOURCE_DO_NOT_DUPLICATE flag prevents that this happens.

test: Fix compiler warnings about incompatible pointer type

Update Restream.io ingests list and set recommended keyframe interval to
2.

Whether buffer size is visible is determined by the value of the "Use

vlc-video: Enable building the plugin on Linux

This fixes a issue on Linux, at least on Ubuntu anyway, where the title bar and unity launcher is shown when the fullscreen projector is active.
