Users with AMD CPUs and Intel dGPUs (Arc) would find that QSV is
restricted to 1200p and missing features due to to this check failing.
Once the encoder gets rewritten for AV1 support we will fix this
properly.
This commit rounds the timestamp to the integer multiple of fps_den.
Prior to this change, since the timestamp in MFX is defined in units of
90 kHz, timestamps for 60000/1001 fps is not accurately expressed. Also
the encoder sometimes returns the decode time stamp slightly off.
Hence, the timestamp in OBS becomes not a multiple of fps_den after
converting back from the timestamp in MFX.
As Intel continues to add discrete graphics cards, maintaining a long
list of discrete device IDs to check against isn't wise. When i+I
platforms are detected, default to integrated graphics.
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.
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 reverts commit 3c22cf35c9802240c4775d98d360601ff2b67905, reversing
changes made to c7dab6c92ba7380b0d91f4a34b1f507a512d581b.
This is being reverted due to many people being unable to start up the
QSV encoder with these changes.

- Allow user to change # of B frames. New Default -> 1
- Allow user to enable Content Adaptive Quantization (MBBRC) if CPU is Skylake or newer.
- Allow user to choose LA_CBR as a rate control.
- LA depth: New Default -> 15, only when LA rate control is used.
Allow multiple QSV encoders, usefull for live + recorded parallel
sessions. The first QSV encoder will create a DirectX device and return
a handle / pointer. Any additional QSV encoder will use that same
pointer to the DirectX device. We keep track of the number of open
QSV encoders so that we wait to close the DirectX resources after all
encoders are closed.

QSV frame priority bits are not being marked correctly; their priorities
are always marked either low or disposable, whereas I-frames should be
marked as highest (3), P-frames should be marked as high (2), and other
frames should be marked as either low or disposable. This helps ensure
that the correct frames are dropped when frames need to be dropped.
When using per-encoder rescaling, QSV would overwrite the current
encoder scale value in the get_video_info callback with the base video
width/height instead of using the current encoder width/height.
