Moves the "Enforce streaming service bitrate" option from simple output
mode to the stream section, renames it to "Ignore streaming service
setting recommendations" (inverting it). When trying to check it, it
will now also display a message box warning the user that it's generally
a not-so-good idea.

Also displays recommended settings for the service.

Refactors a bit of code to make it easier to get the current stream
service object in the settings

(This commit also modifies rtmp-services)

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.

decklink: Fix compiling on linux

Typo left headers as source files so required functions were never
compiled in.

fixes #3699

Adds a VOD track option (specific to Twitch) that allows a user to
specify which audio track to use for their Twitch VODs, which uses a
separate encoder to encode the track. This allows users the ability to
choose what audio goes on their VOD, separately from the live stream.

decklink: Fix format detection loop

decklink: Upgrade sdk to version 11.6

Remove BUILD_CAPTIONS build flag

Ignore color space change in format detection to fix endless loop.
Fix #3511
Fix #3277

(This commit also modifies libobs, UI)

v4l2_outputparm includes unused fields, defined as
	__u32		reserved[4]

Accesses to reserved[4] was out of bounds.  Fix this and simplify by
just zeroing the entire struct v4l2_streamparm instead.

Using modinfo dumps all the output into the terminal instead redirect
all output to dev/null.

It's possible for files to have some/all characters uppercase.

Fixes #3562

CONTRIBUTING.rst: Update CONTRIBUTING doc

Update link to compiling and building instructions to point to the
GitHub repo at the "obsproject" org URL. Replace link to Mantis with
link to GitHub Issues for our bug tracker to mirror the contents in
README.rst.

We disable the stream encoder setting in Advanced Output Mode when an
output is active, so let's also disable the stream encoder setting in
Simple Output Mode when an output is active.

UI: Enable sps/pps (video headers) repetition (for srt/mpegts)

fixes: obsproject#3053

Using a fixed path would allow malware on a compromised system to
perform a DLL planting attack. Reported by Erik Wynter.

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.

Add YouTube RTMPS service to services.json as a beta.

Viloud is an online video platform for creating and streaming live,
linear and on-demand TV channels.

Fixes a null pointer dereference in the output filter, and fixes a bug
where the output filter would incorrectly hold a reference to the filter
graph.

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.
