Intel committed an NDA disclaimer on each source file. The stated
intention was that the NDA "added to OBS doesn't apply to open source
code once it's been accepted by the community. You can remove it for
your modifications". This quote is from an email chain involving
Intel's legal team and developers. The NDA in the source files
mistakenly triggers source code scanners that look for license
violations. I have removed the comments that contain the NDA.
Unfortunately these encoders tend to crash or freeze after after
multiple bitrate changes. Users with dynamic bitrate enabled
experience a random encoder freeze which manifests as OBS dropping to
0kb/sec and disconnecting and it's not at all obvious that dynamic
bitrate is the cause. Disable it for now until we can figure out if
there is any workaround or bug on our end.
Fix for an issue found where new "Latency" and "Subjective Video
Enhancement" options where always using default settings even after
being changed in UI. This issue was introduced when mapping old QSV
settings to new ones.
Simplify UI options by combining LookAhead Depth and Async Depth into
latency mode option. Ultra-low, low, and normal will set these two
encode parameters accordingly.

Enables a pipeline for texture-based encoding with QSV. Utilizes OBS
NV12 output for encode to avoid offloading them from GPU, which will
increase performance. The option to select old QSV pipeline still
remains and will fallback if new pipeline fails.
PR #1937 (commit b9ad1ce) added QSV target usage options, but there was
a comma missing between two of the array entries. This resulted in
"faster" and "veryfast" becoming "fasterveryfast", which is not valid.
Code style changes were required by .clang-format.
Add the option to enable custom quantization matrix for game streaming
on ICL for better subject quality. Feature is only supported with AVC
high profile, so added function to detect when QSV profile is modified
and hide or show CQM UI option accordingly. Also, increase SPS/PPS
buffer sizes since matrix is stored in SPS/PPS.
Enable B-Pyramid frames to improve quality for high motion content.
B-pyramid allows a B-frame to choose closer frames for reference which
may have higher correlation.
Adjusts packet priority to avoid dropping referable B-frames
A check has been added to ensure feature is enabled only on platforms
with MSDK API 1.8 or higher - addresses crashing issues.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
This patch fixes QSV failing with new DCH graphics drivers. QSV is not
initializing under certain conditions when the graphics adapter 0 is not
set to iGFX due to outdated MSDK dispatcher. Updating to MSDK with new
dispatcher to enable proper initialization of QSV encoder with DCH
drivers.
