On Windows 10 and up, D3D11 should never fail, so the D3D9 code should
no longer be possible to hit. As far as I can tell, this code was mostly
for Windows 7/8/8.1 and it was part of the initial implementation. It
should no longer be needed.

Revert "obs-qsv11: Use d3d9 allocator on Win7"
This reverts commit b276b1633e.
This reverts the changes to Windows where Release() was called every
time, since we need share a single DX context across multiple encoders.
Instead introduce a ReleaseSessionData() function and some platform
specific session data that will be passed to it. We use this to track
the VA-API display and fd to release them at the right time. Leaking
displays will also lead to cache pollution in the intel-media-driver
crashing users so we cannot do that.

For some reason, using MFX_SCENARIO_GAME_STREAMING causes the keyframe
quants to be higher than other frames, which is not desirable. In turn,
this causes bitrate to be higher than the target bitrate for a sustained
period of time after each keyframe.
Not setting the scenario removes this behavior and returns CBR to
somewhat reasonable levels of consistency.

Trying to use the display server as the QSV device was found to be
generally wrong in beta, so instead lets save defaults from the earlier
device enumeration similar to obs-ffmpeg-vaapi which is known to work
well.
Setting AdaptiveCQM to ON when LowPower is OFF crashes the
intel-oneapi-gpu implementation on Linux when using the AV1 encoder.
But using the same LowPower settings as Windows works so lets drop the
current guards.
Enable Low Power Look-ahead (VDENC LA) after Intel Arc Graphics. Change
LA_DEPTH defaults (60 frames for normal latency and 30 frames for low
latency). Keep VME Look-ahead only for certain Intel platforms (ICL,
TGL, ADL, and RPL). Disable VME LA for HEVC
* Change GopPicSize default to 240
* Remove GopOptFlag
* Change keyint_sec default from 3 to 0
* Reduce keyint_sec minimum value from 1 to 0 (for auto)
This cleans up the fairly arbitrary Windows includes and types and
unused functions from the common code and replaces them with platform
independent equivalents, or platform specific implementations in
common_utils.
This removes the Windows 8 support to avoid adding an additional
platform function to query this. OBS only supports Windows 10
officially, so it's about time we removed it.
Replace the checks based on D3D11 and D3D9 to check a more informative
variable aptly named UseTexAlloc for which memory allocator should be
used within the encoder.
The query being done will ovewrite ALL invalid parameters. This results
in invalid parameters that are not LowPower settings being overwritten
with 0 either introducing different errors or possibly different
behavior.
Neither the mfxExtMasteringDisplayColourVolumme and
mfxExtContentLightLevelInfo structures appear to be supported when using
AV1, so if using AV1, do not include these structures.
It's unknown as to why AV1 fails to initialize when using either of
these extended structures as part of its configuration parameters.
Either they're completely unsupported or there's a member variable that
causes initialization to fail.
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.
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 3c22cf35c9, reversing
changes made to c7dab6c92b.
This is being reverted due to many people being unable to start up the
QSV encoder with these changes.
