Allow outputs to force a stop even when already in the process of
stopping. If for example a stream is heavily congested and taking a
very long time to stop, this allows frontends to give the users the
option to forcibly stop the stream to make it stop as quickly as
possible.
Allows getting the current active framerate that the core is rendering
with. This takes in to account any rendering lag or stalls that may be
occurring.
Outputting a human-readable error message on library load failure makes
it a little bit easier for plugin developers to determine why a plugin
library may have failed to load (such as missing dependency), rather
than having to look up the error code each time.
Closesjp9000/obs-studio#596
P-frames were initially set as highest priority to prevent them from
being dropped (not sure what the rationale was behind this), but this
caused a problem where if there's too much congestion for whatever
reason data will continue to stay buffered, so to prevent this p-frames
should be droppable.

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.
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.
The active_refs and show_refs variable would only increment/decrement
their children if their values were 1 and 0, which means that in the
case of scenes within scenes, sub-sources of scenes within scenes would
end up having the wrong ref values.
Allows the ability to use scale filters such as point, bicubic, lanczos
on specific scene items, disabled by default. When using one of the
latter two options, if the item's scale is under half of the source's
original size, it uses the bilinear low resolution downscale shader
instead.
Adds a function to the C-family parser to go to the next token and
create a string copy of it. Useful for when you want to get a copy of
the next token regardless of what type it is.
This fixes an design flaw where a delayed output would schedule a
stop even while in the process of reconnecting instead of just shutting
down right away.
When obs_output_actual_stop is called on shutdown, it should wait for
the output to fully stop before doing anything, and then it should wait
for the data capture to end. The service should not be removed until
after the output has stopped, otherwise it could result in a possible
memory leak on stop. Packets should be freed last.
(Note: This commit also modifies obs-ffmpeg and obs-outputs)
API Changed:
obs_output_info::void (*stop)(void *data);
To:
obs_output_info::void (*stop)(void *data, uint64_t ts);
This fixes the long-time design flaw where obs_output_stop and the
output 'stop' callback would just shut down the output without
considering the timing of when obs_output_stop was used, discarding any
possible buffering and causing the output to get cut off at an
unexpected timing.
The 'stop' callback of obs_output_info now takes a timestamp with the
expectation that the output will use that timestamp to stop output data
in accordance to that timing. obs_output_stop now records the timestamp
at the time that the function is called and calls the 'stop' callback
with that timestamp. If needed, obs_output_force_stop will still stop
the output immediately without buffering.
Fixes an issue where the audio meter/fader would call an obs function
and lock another mutex, potentially causing a mutual inverted lock in
another thread.
When using GPU conversion for 4:2:0 frames on async video sources, it
would create a texture bigger than necessary and try to copy too much
data from the frame, resulting in a crash.
